Why?** + +The project I'm most proud of is [**DotVerse**](https://github.com/alaotach/dotverse), a realtime multiplayer pixel-art metaverse. But honestly, what I'm proud of isn't the product, it's surviving one particular bug that drove me insane for days. +Pixels were broken in three different ways at once. Sometimes you'd draw something and it would just disappear a second later. Sometimes your pixels would show up for everyone else but not for you. Sometimes they wouldn't update at all. And the thing that made it genuinely maddening was that none of this was consistent, it would happen randomly, so I couldn't even reliably reproduce it to debug it. I spent a lot of time just staring at the screen trying to catch it happening. +After a lot of trial and error I finally traced it back to something embarrassingly simple: I was spamming the websocket. When you drag to draw, you're touching a new pixel on basically every frame of mouse movement. I was emitting a separate event for every single one of those pixels. The server was getting flooded, events were racing each other, and state was ending up different on different clients depending on which events arrived in which order. The connection was dropping frames under load and nobody's canvas agreed on what was true. +The fix wasn't complicated once I understood what was happening. I stopped emitting per-pixel and started batching, collect everything touched during a drag, send it all together when the drag ends. Combined with server-side sequencing so clients process updates in order, all three failure modes went away at once. +That one debugging session shaped the whole rest of the architecture. The canvas world server (Node.js + Socket.IO) and the minigame server (Python websockets, handling lobbies, voting, scoring) are separate processes, partly because I learned the hard way that mixing two different consistency requirements into one server makes both of them worse. +I mention all this because it's directly relevant to why I want to build the WebSocket module in API Dash. I'm not coming at this theoretically, I know where these systems actually break, because I've been the person staring at a canvas wondering why my own pixels aren't showing up for me. + +### 3. **What kind of problems or challenges motivate you the most to solve them?** + +I am most motivated by problems where there is no obvious existing solution, especially when people assume they are too hard or impractical to build. + +I have an entrepreneurship-oriented mindset, so I naturally gravitate toward technically difficult ideas with strong real-world use. For example, I am currently exploring: + +- a mobile-GPU AI inference/training platform to coordinate model workloads across clusters of multiple phones, +- a mobile AI agent with on-device vision and deep device control to execute real tasks (from app flows to automation), +- and a websocket-synced Android lock-screen drawing experience where actions are mirrored in real time across devices. + +What motivates me is the combination of technical depth, product-level constraints, and user impact. I enjoy turning "this should be impossible" into something reliable enough to demonstrate and iterate. + +### 4. **Will you be working on GSoC full-time? In case not, what will you be studying or working on while working on the project?** + +Yes, full-time. GSoC is my main commitment during the coding period and I'm treating it that way. +I won't pretend I have zero going on, because I'm in college, I have side projects, and I've worked with clients. But honestly that's exactly why I'm not worried about this. Client work taught me that deadlines are real, communication matters, and you don't get to disappear when things get hard. I bring that same accountability here. I'll show up every week, flag blockers early, and I won't let review turnaround become a bottleneck on the mentor's end. + +### 5. **Do you mind regularly syncing up with the project mentors?** + +Not at all, I actually prefer it. I learned this the hard way with my first client. They were pretty quiet throughout the project, I kept building, and when I handed them the final product they said they didn't want it running on the PC itself, they wanted it on the cloud. Suddenly I'm dealing with containers, Kubernetes, deployment pipelines, things that weren't in the original plan at all. It took a lot of extra effort that could've been avoided with one conversation early on. +That experience genuinely changed how I work. Regular syncs aren't overhead to me anymore, they're how you avoid expensive surprises at the end. I'd rather flag a blocker or a design question on Monday than explain a derailed week on Friday. I'll bring progress openly, show what's working and what isn't, and if I'm choosing between two implementation approaches I'll bring both to the mentor instead of silently picking one. + +### 6. **What interests you the most about API Dash?** + +Honestly, I've felt the pain this tool is trying to solve. +When I was building **Aloo Bot**, backed by hundreds of different APIs, I wasn't even using proper tools. I had a Python script I'd manually modify every time I needed to test something different. Change the endpoint, change the payload, run it, check the output, repeat. For REST that was annoying. When I got into trading automation with Binance and Bybit, testing exchange APIs under real latency pressure with that same script was genuinely painful. Every test was a manual edit away and there was no visibility into what was actually happening on the wire. +API Dash is the tool I wished existed back then. It already has a solid cross-platform foundation and a clean architecture, it's not a toy, it's something developers actually use. And it's open source, which means when I add WebSocket, MQTT, and gRPC support, it's not a feature locked inside one company's product, it's available to every developer who's still out there editing Python scripts to test their APIs. +That's what interests me most. Not just the technical challenge, but the fact that shipping this actually makes something meaningfully better for people who build what I build. + +### 7. **Can you mention some areas where the project can be improved?** + +The obvious one is what this proposal is about, WebSocket, MQTT, and gRPC support. But a few things I noticed while actually working in the codebase: +Long-running sessions have almost no observability. If you're connected to a WebSocket for ten minutes and something goes wrong, there's not much to help you understand what happened, no message timeline metadata, no transport diagnostics, no way to replay the session. For debugging real production issues that's a real gap. +The history is useful but lightweight for protocol sessions. It shows that a request was made but not much about what the session looked like, how long it ran, how many messages exchanged, whether it disconnected cleanly. That context matters when you're debugging intermittent failures. +Contributor onboarding for protocol work is thin. The existing docs cover HTTP well but if someone wanted to add a new protocol or extend an existing one, there's not much guiding them through the provider/model/service pattern. That slows down community contributions. +And one small UX thing — advanced controls in the editor panes could be organized more consistently. Right now different panes handle progressive disclosure differently, which adds friction when you're switching between protocols. + +### 8. **Have you interacted with and helped API Dash community? (GitHub/Discord links)** + +Yes. I have interacted through issue-driven PR work and community contribution channels. + +I have actively worked on real issues, submitted PRs, and built idea/prototype artifacts specifically for API Dash’s GSoC direction. + +Recent PoC contribution evidence: + +- GSoC PoC PR: [#1473](https://github.com/foss42/apidash/pull/1473) + - Title: Add MQTT, WebSocket, and gRPC support to API Dash (PoC) + - Status: Open (from `alaotach:poc` to `foss42:main`) + - Scope: 14 commits, 57 files changed, +23,416 / -1,256 lines +- PoC demo video: [Google Drive demo](https://drive.google.com/file/d/1ufOMtceT_AyjXEdzWkwdhDEFOvwThADI/view?usp=sharing) + +--- + +### Project Proposal Information + +## Proposal Title + +**WebSocket, MQTT, and gRPC Support in API Dash** + +## Abstract + +API Dash is excellent for HTTP, but a large chunk of modern backend systems don't speak HTTP. WebSocket powers real-time dashboards and chat. MQTT runs IoT sensors and telemetry pipelines. gRPC connects microservices and ML infrastructure. Right now, developers testing these systems have to leave API Dash entirely and juggle separate tools, or do what I used to do, which is maintain a Python script they modify by hand every time. + +This project adds first-class support for all three protocols directly inside API Dash. Not as experimental add-ons as complete workflows with their own request models, connection state, message timelines, and debugging tools, built on the same provider/service/model architecture the codebase already uses for REST. + +By the end of GSoC, a developer should be able to open API Dash and: +- connect to a WebSocket endpoint, send and receive messages, and replay a session for debugging +- connect to an MQTT broker, publish and subscribe across topics with QoS controls +- invoke a gRPC method via server reflection without needing a `.proto` file on hand + +All of this while the existing HTTP workflows stay completely untouched and with production-grade UX patterns for reliability, observability, and reproducibility. + +3. **Detailed Description** + +![](https://github.com/foss42/apidash/assets/615622/493ce57f-06c3-4789-b7ae-9fa63bca8183) + +## 3.1 Problem Statement and Need + +Most backend systems today aren't pure REST. WebSocket handles real-time event streams and bidirectional channels. MQTT drives IoT telemetry and broker-mediated messaging. gRPC powers contract-first microservice communication. But API Dash currently has no support for any of them. + +That forces developers into a fragmented workflow, a different tool for each protocol, repeated environment setup, no shared history, and no way to reproduce a debugging session across systems. I know this firsthand because before I found proper tooling I was doing all of this with a Python script I'd manually edit every time I needed to test something different. + +This project closes that gap directly inside API Dash. One tool, all four protocols, the same UX. + +## 3.2 Existing Codebase Grounding + +Before writing any proposal I spent time actually reading the codebase to find where protocol support would need to plug in. Three files are the key extension points: + +- `packages/better_networking/lib/models/http_request_model.dart` — where the existing HTTP request model lives. New protocol models need to follow the same pattern rather than extending this one, which was the root cause of failure in previous MQTT and WebSocket PRs. +- `lib/screens/home_page/editor_pane/details_card/request_pane/request_pane.dart` — where API type switching decides which editor to render. This is where new protocol panes get routed in. +- `lib/providers/collection_providers.dart` — where `sendRequest()` orchestrates execution. This is where the protocol router hooks into the existing flow without breaking HTTP. + +I also searched all `APIType` switch callsites across the codebase to map every place that needs updating when a new protocol is added, not just the obvious ones. + +## 3.3 Proposed Architecture Extension + +The core decision here is to not touch the existing HTTP abstractions at all. Previous PRs that tried to reuse `HttpRequestModel` for WebSocket and MQTT ended up breaking things or losing state — the models have fundamentally different shapes and lifecycles. Each protocol gets its own dedicated model instead: + +- `WebSocketRequestModel` +- `MqttRequestModel` +- `GrpcRequestModel` + +Execution routes through a clean dispatch chain: +``` +RequestExecutor → ProtocolRouter → ProtocolHandler +``` + +HTTP hits the existing pipeline unchanged. Every new protocol hits its own handler, with its own state machine and validation logic, completely isolated from the others. + +Four design goals drove every decision here: + +- **Isolation** — protocol-specific state and validation lives in its own model, not bolted onto HTTP abstractions +- **Non-regression** — existing HTTP, REST, and GraphQL workflows are untouched by any of this +- **Incremental delivery** — the architecture slices cleanly into small PRs: routing baseline first, then one protocol at a time +- **Extensibility** — adding a fourth protocol in the future means adding a new handler, not rearchitecting the existing ones + +![](https://github.com/user-attachments/assets/c2933c78-806e-48c6-968e-36a3995bdef6) + +## 3.4 WebSocket Module + +The WebSocket module is the most complete of the three in the PoC. Here's what it covers: + +### 3.4.1 Transport and Connection Behavior + +- `ws://` and `wss://` support with TLS certificate introspection +- Custom headers and query parameters on the handshake request +- Explicit connection lifecycle — connecting, connected, reconnecting, disconnected, error each with appropriate controls enabled or disabled +- Reconnect policies with exponential backoff +- Keepalive with ping/pong visibility in the message timeline + +### 3.4.2 Message Handling + +- Send and receive text, JSON, and binary payloads +- Timeline view with sent/received direction indicators, sequence numbers, timestamps, and payload size +- Binary-safe rendering with configurable decoder (UTF-8, hex, base64) +- Search and filter across the message timeline + +### 3.4.3 Advanced Tooling + +- Decoder pipeline — upload a Protobuf descriptor, FlatBuffers schema, or Avro schema to decode binary messages automatically +- Session export and import in JSONL format for reproducible debugging +- Replay controls — replay sent-only or full session, with speed and jitter controls +- Transport diagnostics — TLS subject, issuer, fingerprint, validity window, frame-level metrics + +### 3.4.4 Persistence + +- Draft connection options saved with request state — reopening a request restores your last URL, headers, and settings +- Session metadata captured for history — duration, message count, connection status, error summary + +> All advanced tooling lives behind a toggle so the default view stays clean. + +## 3.5 MQTT Module + +### 3.5.1 Broker Connectivity + +- Broker host/port with TLS toggle (`mqtts://`) +- Client ID, username/password auth +- Connection status that actually tells you what went wrong, CONNACK return codes mapped to human-readable messages (identifier rejected, bad credentials, not authorized) instead of a generic "connection refused" +- Protocol version selector (3.1.1 / 5.0), keep-alive interval, and clean session controls +- Live status bar showing connection state, message counts, throughput, latency, and last message time at a glance + +### 3.5.2 Pub/Sub Workflows + +- Publish to any topic with QoS (0 at-most-once, 1 at-least-once, 2 exactly-once) and retain flag — with payload templates for quick JSON scaffolding +- Dynamic subscribe and unsubscribe — add topics with individual QoS levels, remove them without reconnecting, active subscriptions shown with live per-topic message rate +- Topic-filtered message stream on the right pane — filter by type (SUB/PUB), search by content, each message shows topic, payload, QoS badge, size, and timestamp +- "Use last sent" shortcut to quickly republish the previous payload + +### 3.5.3 Diagnostics and Replay + +- Live status strip — msgs/s, sent count, recv count, throughput in B/s, latency, connect attempts, time since last message +- Session export and import in JSONL format +- Deterministic replay with speed scaling and seeded jitter for reproducing timing-sensitive bugs +- All replay and advanced controls grouped behind an Advanced toggle to keep the default view clean + +### 3.5.4 Scope Note + +The primary target is a stable, reliable MQTT workflow — connect, publish, subscribe, debug, replay. Broker-specific edge cases and extended protocol tuning will be tracked as follow-up work after the core lands. + +## 3.6 gRPC Module + +### 3.6.1 Discovery and Schema Handling + +- **Reflection-first** — connect to any gRPC server with reflection enabled and the Service Explorer populates automatically. No `.proto` file needed. Services and methods browse instantly from the left panel. +- **`.pb` descriptor import** as fallback for production servers with reflection disabled, simpler and more reliable than maintaining a proto text parser +- Service/method tree maps directly to the request builder, selecting a method generates the correct form fields from the descriptor at runtime + +One non-obvious thing I ran into while building this: the reflection RPC itself is a bidi-streaming call. When it finishes and the stream closes, some servers respond with an HTTP/2 `GOAWAY` that kills the entire shared channel, so the actual RPC call right after reflection would fail with a connection error. The fix is a **separate ephemeral channel** for reflection only, shut down cleanly after discovery, then a fresh channel for real calls. That's now baked into the architecture. + +### 3.6.2 Invocation Workflows + +- Connection target with TLS toggle and metadata (gRPC headers) per call +- Request builder in two modes — **Form Mode** (typed fields generated from the descriptor, + with correct input types for string/bool/enum/bytes/nested messages) and **JSON Mode** for + power users +- All four call types supported: Unary, Server Streaming, Client Streaming, Bidirectional +- Response pane shows body, headers, trailers, and a timeline — each streaming message + rendered as a separate timestamped card +- Invoke gating — the Invoke button stays disabled until both connection and descriptor are + ready, preventing invalid execution states + +### 3.6.3 Encoding/Decoding Strategy + +No generated stubs — API Dash doesn't have compiled `.proto` files at runtime. The dynamic encoder handles all 15 protobuf field types directly from the descriptor: + +- **Varints** (wire type 0): int32, uint32, sint32/64 with ZigZag, bool, enum +- **Fixed-width** (wire types 1 & 5): float, double, fixed32/64, sfixed32/64 +- **Length-delimited** (wire type 2): string, bytes, nested messages + +Wire type correctness matters here — a wrong wire type corrupts the length prefix and every field after it becomes garbage. The encoder writes raw `ByteData` directly rather than trying to use the `protobuf` package's `CodedBufferWriter` (which is designed for generated code, not dynamic use). + +--- + +## 3.7 ConnectRPC Direction (Stretch) + +ConnectRPC support is a stretch goal, explicitly deferred until core protocol stability lands. The approach would layer through existing HTTP service primitives with protocol-specific envelope and header handling, reusing the gRPC editor path. If core delivery finishes ahead of schedule this gets picked up, otherwise it becomes a post-GSoC follow-up PR. + +--- + +## 3.8 UI/UX Integration Plan + +All three protocol panes follow the same conventions API Dash already uses: + +- **Compact default surface** — the view you see on open shows only what you need to make a + connection and send a message +- **Advanced options behind toggles** — replay controls, decoder uploads, diagnostics, + extended settings all hidden until you need them +- **Timeline/log first** — the response pane leads with the message stream, not metadata +- **Safe state transitions** — controls enable and disable based on connection state. + You can't send before connecting, can't subscribe before the broker confirms, can't invoke + before the descriptor is loaded +- **Consistent across protocols** — same connect/send/log/replay pattern on every pane so + switching protocols doesn't require relearning the UI + +### MQTT Pane + +Three-panel layout — connection and topics on the left, publish controls in the center, live message stream on the right. The status bar across the top shows connection state, message counts, throughput, and latency at all times so you never have to dig for it. Advanced replay, import/export, and extended broker settings live behind an Advanced toggle and don't clutter the default view. + +### WebSocket Pane + +URL bar at the top, message timeline in the center, send box at the bottom — the same mental model as a chat client because that's what makes sense for a bidirectional stream. Sent and received messages are visually distinct. Filters and search sit above the timeline. Transport diagnostics (TLS cert info, frame metrics, sequence gaps) and decoder/replay controls are behind a Hide/Show advanced toggle so they're one click away but not always in your face. + +### gRPC Pane + +Service Explorer on the left for browsing discovered services and methods. Request Builder in the center with Form Mode and JSON Mode, generated directly from the runtime descriptor. Response pane on the right showing body, headers, trailers, and a per-message timeline for streaming calls. Reflection and `.pb` import controls are in the Service Explorer panel — where you'd naturally look when setting up a connection, not buried in settings. + +## 3.9 History and Persistence Strategy + +HTTP requests have a clean request/response pair, easy to store. Protocol sessions don't. A WebSocket session might run for twenty minutes and exchange thousands of messages. Storing everything by default would bloat history fast and make it unusable. + +The approach is lightweight summary metadata per session: + +- session duration +- message counts (sent/received) +- final connection status +- error summary if it ended badly +- reference to the exported JSONL file if the session was explicitly saved for replay + +Full payload history is opt-in via export, not automatic. This keeps the history sidebar useful, you can see at a glance what happened in a session without loading the entire message log, and lets users decide for themselves when a session is worth keeping in full. + +Draft connection options (URL, headers, broker settings, last payload) are persisted with the request state so reopening a request puts you back where you were. + +## 3.10 Testing Strategy + +Testing is staged by milestone — unit tests land with each feature PR, not saved for the end. The goal is to catch regressions at the PR level, not during a final stabilization sprint. + +### Unit Tests + +The boring but essential layer — protocol models, parser/serializer transforms, provider state transitions, and invalid-input handling. These run fast and catch the class of bugs that are hardest to spot in a running app: wrong field defaults, serialization edge cases, state machine transitions that skip a step. + +### Widget Tests + +Pane-level interactions — connect button enables and disables at the right times, advanced panel shows and hides correctly, inline validation errors appear and clear on user input, disabled states actually prevent actions. These exist because a lot of subtle UX bugs only show up when you simulate real interaction sequences. + +### Integration Tests + +End-to-end flows against real test servers: +- WebSocket echo endpoints for send/receive round-trips and reconnect behavior +- Public MQTT test brokers (broker.hivemq.com) for publish/subscribe workflows +- gRPC sample services (grpcb.in) for both reflection-enabled and descriptor-import paths + +### Regression Safety + +Every protocol PR runs the existing REST, GraphQL, and AI workflow tests before merge. Editor switching and history behavior get explicit checks — these are the two surfaces most likely to silently break when new protocol routing is added. + +## 3.11 Reliability and Risk Management + +Four risks worth being honest about upfront, and what I'm doing about each: + +**1. Transport edge cases** +WebSocket fragmentation, MQTT broker quirks, gRPC servers that send `GOAWAY` after reflection — these don't show up in happy-path testing. Mitigation is staged rollout with protocol-specific diagnostics built in from day one, not added later. If something breaks silently, the diagnostics surface should tell you where. + +**2. UI complexity growth** +Three new protocol panes is a lot of surface area. The risk is that each one slowly accumulates controls until the default view is overwhelming. Mitigation is the Advanced toggle pattern applied consistently — high-frequency controls always visible, everything else hidden until needed. This is enforced at the design level, not just aspirationally. + +**3. State migration and regression risk** +Adding new fields to protocol models means older persisted sessions might be missing those fields on load. I hit this during PoC development — hot reload would create stale state objects that crashed on newly added non-null fields. Mitigation is defensive defaults everywhere: nullable counters with `?? 0` fallbacks, backward-safe model evolution, and migration checks before each protocol merge. + +**4. Over-scoping** +Three protocols in twelve weeks is ambitious. The risk is trying to do too much on each and shipping none of them properly. Mitigation is a hard core/stretch boundary — unary gRPC before streaming, stable MQTT before MQTT v5, working WebSocket before advanced decoder pipelines. Stretch items are real planned work, not vague aspirations, but they don't block core delivery. + +### 3.11.1 Feature and Implementation Tradeoffs + +This project is intentionally designed around explicit tradeoffs so the implementation stays practical, reviewable, and shippable within GSoC timelines. + +1. **Breadth (3 protocols) vs depth (one protocol with many advanced features)** + - Decision: deliver production-usable core workflows for WebSocket, MQTT, and gRPC first. + - Benefit: API Dash becomes a true multi-protocol client. + - Tradeoff: some advanced features (for example, richer codec/plugin pipelines or expanded gRPC streaming helpers) may remain stretch items. + +2. **Stable UX consistency vs protocol-specific flexibility** + - Decision: keep pane structure and controls consistent across protocols (connect/send/log/replay), while exposing protocol-specific controls in advanced sections. + - Benefit: lower user learning curve and easier maintenance. + - Tradeoff: protocol power users may need one extra click for advanced controls. + +3. **Compact default UI vs feature discoverability** + - Decision: place heavy options (codec uploads, replay controls, import/export, extended MQTT settings) behind Advanced toggles. + - Benefit: avoids editor clutter and layout instability. + - Tradeoff: discoverability of advanced capabilities is slightly reduced; mitigated with labels/tooltips and docs. + +4. **WebSocket low-level diagnostics vs implementation complexity** + - Decision: retain useful transport/TLS diagnostics and sequence tracking in service/provider layers. + - Benefit: better debugging for real production socket issues. + - Tradeoff: service internals become more complex and require stronger test coverage and refactoring discipline. + +5. **MQTT operational completeness vs initial simplicity** + - Decision: prioritize practical MQTT session flows (connect/publish/subscribe/unsubscribe/history/replay) over broker-specific edge-case tuning. + - Benefit: reliable day-to-day MQTT usage lands sooner. + - Tradeoff: some specialized broker behaviors and performance tuning knobs are deferred. + +6. **gRPC reflection-first onboarding vs guaranteed compatibility** + - Decision: support reflection and descriptor-driven workflows in a single editor path. + - Benefit: easier service exploration and method discovery for most users. + - Tradeoff: reflection-disabled environments need stronger manual descriptor handling and validation paths. + +7. **Replay fidelity vs storage/runtime cost** + - Decision: persist protocol events and support JSONL import/export for reproducible replay. + - Benefit: deterministic debugging and sharable sessions. + - Tradeoff: larger histories increase disk usage and replay orchestration complexity; mitigated by filtering and bounded retention defaults. + +8. **Strong model typing vs migration effort** + - Decision: extend protocol request/session models explicitly instead of loosely typed payload blobs. + - Benefit: safer state transitions and easier long-term maintainability. + - Tradeoff: migration/model-update overhead increases in the short term. + +9. **Delivery speed vs test depth** + - Decision: stage tests by milestone (unit -> widget -> integration) and enforce regression checks before each protocol merge. + - Benefit: better release confidence and lower regression risk. + - Tradeoff: slower short-term iteration during feature spikes. + +10. **Ambitious scope vs predictable execution** + - Decision: keep strict core/stretches boundaries and publish milestone-level acceptance criteria. + - Benefit: mentors can evaluate progress objectively and unblock quickly. + - Tradeoff: attractive but non-critical enhancements may be postponed to post-GSoC follow-up PRs. + +## 3.12 Deliverables Summary + +**Core** +1.

Current PoC evolved as a large exploratory branch and still needs to be split into tightly scoped, review-friendly pull requests. + +2. **Automated test coverage is not complete for all protocol paths** + - Core runtime behavior was validated through iterative manual testing and diagnostics. + - Full unit/widget/integration coverage for all newly added protocol interactions is still pending. + +3. **gRPC deep streaming maturity is not fully complete** + - Unary and primary invocation paths are the focus of current stability. + - Client-streaming and bidirectional-streaming require dedicated production hardening and broader test fixtures. + +4. **ConnectRPC path is not completed** + - It is designed as a stretch direction and intentionally deferred until core protocol stability lands. + +5. **Long-run stress and soak reliability testing is pending** + - Reconnect loops, long session replay, and high-volume message streams still require systematic stress benchmarks. + +6. **Final documentation package is not complete yet** + - User guides, developer extension notes, and protocol troubleshooting docs must be completed to production quality. + +7. **Compatibility/migration hardening for all persisted states is not finished** + - Additional backward-compatibility checks for older stored sessions and metadata are planned. + +### 3.15.2 What will be done during GSoC to close the gap + +1. **Convert monolithic PoC into structured milestone PRs** + - Router/model baseline PR. + - WebSocket core PR. + - WebSocket diagnostics/replay PR. + - MQTT core PR. + - MQTT advanced/replay PR. + - gRPC discovery/invoke PR. + - Persistence/history PR. + - Stabilization/tests/documentation PR. + +2. **Complete protocol-specific automated testing matrix** + - Unit tests for request models, provider state transitions, validation guards, and serialization behavior. + - Widget tests for pane controls, advanced toggles, disabled states, and error rendering. + - Integration tests against WebSocket echo endpoints, MQTT brokers, and gRPC discovery/invoke scenarios. + +3. **Finalize gRPC roadmap incrementally** + - Stabilize unary and server-streaming behavior first. + - Implement and validate client-streaming and bidirectional-streaming as planned stretch milestones. + +4. **Implement ConnectRPC stretch integration only after core stability gates pass** + - Reuse existing HTTP pathways with protocol-specific envelope/header handling. + - Add targeted tests and documentation if included in final scope. + +5. **Run reliability hardening and performance validation** + - Reconnect/disconnect chaos testing. + - Replay determinism and jitter behavior verification. + - Narrow-layout and long-session UI stability checks. + +6. **Ship complete documentation and contributor guidance** + - End-user docs for each protocol workflow. + - Contributor docs for architecture, extension points, and test strategy. + - Troubleshooting matrix for protocol-specific failure modes. + +### 3.15.3 Planned Refactoring of PoC Code During GSoC (Detailed) + +Refactoring the current PoC code is an explicit GSoC task, not an optional cleanup pass. The goal is to preserve feature behavior while improving maintainability, testability, and long-term contributor velocity. + +#### Refactoring objectives + +1. Reduce monolithic service/provider/widget methods into composable units. +2. Isolate protocol business logic from UI rendering code. +3. Standardize session state transitions across WebSocket, MQTT, and gRPC. +4. Improve naming consistency, error surface clarity, and diagnostics boundaries. +5. Make critical flows easier to unit test without relying on full UI integration paths. + +#### Planned refactoring scope + +1. **WebSocket service and provider decomposition** + - Split connection lifecycle, telemetry updates, and message dispatch into dedicated helpers. + - Keep transport diagnostics handling in a dedicated diagnostics path to reduce coupling with send/receive logic. + +2. **MQTT provider and pane separation of concerns** + - Move replay/import/export orchestration out of large widget-state methods into focused controller/service utilities. + - Keep UI state minimal and delegate protocol actions to testable provider/controller layers. + +3. **gRPC editor execution path cleanup** + - Separate discovery/descriptor resolution from invocation execution flow. + - Keep request shaping, invocation, and response rendering as explicit pipeline stages. + +4. **Cross-protocol consistency layer** + - Align lifecycle state naming and transition semantics across protocol providers. + - Introduce shared patterns for connection status, error reporting, and replay metadata handling where appropriate. + +#### Execution approach + +1. Refactor in small PRs with no intentional behavior change. +2. Add or update tests before and after each refactor slice to validate parity. +3. Use milestone-level checklists to confirm no UX regressions in protocol panes. +4. Keep each refactor PR scoped to one primary surface (service, provider, or UI pane) for reviewer clarity. + +#### Measurable outcomes + +1. Reduced method/class complexity in the largest protocol surfaces. +2. Increased unit-testable logic outside widget state classes. +3. Clearer ownership boundaries between protocol transport, state orchestration, and UI layers. +4. Lower review friction for follow-up feature PRs due to cleaner architecture. + +### 3.15.4 Definition of done for production completion + +The protocol work will be considered production-ready only when all of the following are true: + +1. Each protocol has stable connect, send, receive, and disconnect behavior. +2. Advanced tooling (replay/import/export/diagnostics) is usable without layout instability. +3. Automated tests cover core and edge-case state transitions. +4. Existing REST/GraphQL/AI flows remain regression-free. +5. Documentation and demo artifacts are complete and reproducible. +6. Refactoring milestones are completed for major protocol surfaces with behavior parity validated by tests. + +## 3.16 Technical Implementation Blueprint (Code-Level Proposal) + +This section provides code-level architecture sketches to make implementation intent explicit and reviewable. + +### 3.16.1 Protocol request contracts + +```dart +enum ProtocolType { http, websocket, mqtt, grpc } + +abstract class ProtocolRequestModel { + ProtocolType get protocol; + String get requestId; + Map toJson(); + List validate(); +} + +class WebSocketRequestModel implements ProtocolRequestModel { + @override + final ProtocolType protocol = ProtocolType.websocket; + + @override + final String requestId; + + final Uri endpoint; + final Map headers; + final List subprotocols; + final bool autoReconnect; + final int keepAliveSec; + + WebSocketRequestModel({ + required this.requestId, + required this.endpoint, + this.headers = const {}, + this.subprotocols = const [], + this.autoReconnect = false, + this.keepAliveSec = 0, + }); + + @override + List validate() { + final errors = []; + if (!endpoint.isScheme('ws') && !endpoint.isScheme('wss')) { + errors.add('Endpoint must use ws:// or wss://'); + } + if (keepAliveSec < 0) { + errors.add('keepAliveSec cannot be negative'); + } + return errors; + } + + @override + Map toJson() => { + 'requestId': requestId, + 'endpoint': endpoint.toString(), + 'headers': headers, + 'subprotocols': subprotocols, + 'autoReconnect': autoReconnect, + 'keepAliveSec': keepAliveSec, + }; +} +``` + +### 3.16.2 Protocol router and execution dispatcher + +```dart +abstract class ProtocolHandler { + Future connect(T model); + Future disconnect(String requestId); + Stream events(String requestId); +} + +class ProtocolRouter { + ProtocolRouter({ + required this.wsHandler, + required this.mqttHandler, + required this.grpcHandler, + }); + + final WebSocketHandler wsHandler; + final MqttHandler mqttHandler; + final GrpcHandler grpcHandler; + + Future execute(ProtocolRequestModel model) async { + switch (model.protocol) { + case ProtocolType.websocket: + await wsHandler.connect(model as WebSocketRequestModel); + case ProtocolType.mqtt: + await mqttHandler.connect(model as MqttRequestModel); + case ProtocolType.grpc: + await grpcHandler.connect(model as GrpcRequestModel); + case ProtocolType.http: + throw UnsupportedError('HTTP handled by existing pipeline'); + } + } +} +``` + +### 3.16.3 WebSocket core implementation (handshake + framing + control frames) + +```dart +class WebSocketTransportCore { + Socket? _socket; + StreamSubscription? _subscription; + final BytesBuilder _rxBuffer = BytesBuilder(copy: false); + final BytesBuilder _fragmentBuffer = BytesBuilder(copy: false); + int? _fragmentOpcode; + + final _events = StreamController.broadcast(); + Stream get events => _events.stream; + + Future connect(WebSocketRequestModel model) async { + final port = model.endpoint.hasPort + ? model.endpoint.port + : (model.endpoint.scheme == 'wss' ? 443 : 80); + + _socket = model.endpoint.scheme == 'wss' + ? await SecureSocket.connect(model.endpoint.host, port) + : await Socket.connect(model.endpoint.host, port); + + await _upgradeHandshake(model); + + _subscription = _socket!.listen( + _onSocketChunk, + onDone: () => _events.add(WsDisconnected()), + onError: (e, st) => _events.add(WsError(e.toString())), + ); + } + + Future _upgradeHandshake(WebSocketRequestModel model) async { + final nonce = base64.encode( + List.generate(16, (_) => Random.secure().nextInt(256)), + ); + + final path = (model.endpoint.path.isEmpty ?

PSI-MI TAB parser (production-ready) +- Acceptance criteria: parser supports MITAB 2.5/2.6 core 15 columns, handles `|` multi-value fields, stores normalized interactors/evidence, and imports a 100k-row benchmark file with resumable progress tracking. + +4. CSV parser with explicit column mapping +- Acceptance criteria: curated CSV template + user mapping UI; validation catches missing mandatory columns and bad identifier patterns; mapped import path writes to same canonical schema as PSI-MI. + +5.

Export module for PSI-MI TAB and CSV +- Acceptance criteria: filtered exports match canonical query results; parity tests verify row counts and mandatory column coverage against golden fixtures. + +7. Containerized development + CI pipeline +- Acceptance criteria: one-command local startup for frontend/api/worker/postgres/redis/minio; CI runs lint, type-check, unit/integration tests, and container build smoke tests. + +8. Website graph visualization for PPI exploration +- Acceptance criteria: Cytoscape.js view supports pan/zoom, layout switch, edge filtering by dataset/evidence/status, node search, and export of current subgraph selection. + +9. Documentation and contributor onboarding +- Acceptance criteria: setup docs, architecture notes, parser-extension guide, and troubleshooting page for failed imports are complete and reproducible on a clean machine. + +### 12.2 Stretch deliverables + +1.

Why?** - -The project I'm most proud of is [**DotVerse**](https://github.com/alaotach/dotverse), a realtime multiplayer pixel-art metaverse. But honestly, what I'm proud of isn't the product, it's surviving one particular bug that drove me insane for days. -Pixels were broken in three different ways at once. Sometimes you'd draw something and it would just disappear a second later. Sometimes your pixels would show up for everyone else but not for you. Sometimes they wouldn't update at all. And the thing that made it genuinely maddening was that none of this was consistent, it would happen randomly, so I couldn't even reliably reproduce it to debug it. I spent a lot of time just staring at the screen trying to catch it happening. -After a lot of trial and error I finally traced it back to something embarrassingly simple: I was spamming the websocket. When you drag to draw, you're touching a new pixel on basically every frame of mouse movement. I was emitting a separate event for every single one of those pixels. The server was getting flooded, events were racing each other, and state was ending up different on different clients depending on which events arrived in which order. The connection was dropping frames under load and nobody's canvas agreed on what was true. -The fix wasn't complicated once I understood what was happening. I stopped emitting per-pixel and started batching, collect everything touched during a drag, send it all together when the drag ends. Combined with server-side sequencing so clients process updates in order, all three failure modes went away at once. -That one debugging session shaped the whole rest of the architecture. The canvas world server (Node.js + Socket.IO) and the minigame server (Python websockets, handling lobbies, voting, scoring) are separate processes, partly because I learned the hard way that mixing two different consistency requirements into one server makes both of them worse. -I mention all this because it's directly relevant to why I want to build the WebSocket module in API Dash. I'm not coming at this theoretically, I know where these systems actually break, because I've been the person staring at a canvas wondering why my own pixels aren't showing up for me. - -### 3. **What kind of problems or challenges motivate you the most to solve them?** - -I am most motivated by problems where there is no obvious existing solution, especially when people assume they are too hard or impractical to build. - -I have an entrepreneurship-oriented mindset, so I naturally gravitate toward technically difficult ideas with strong real-world use. For example, I am currently exploring: - -- a mobile-GPU AI inference/training platform to coordinate model workloads across clusters of multiple phones, -- a mobile AI agent with on-device vision and deep device control to execute real tasks (from app flows to automation), -- and a websocket-synced Android lock-screen drawing experience where actions are mirrored in real time across devices. - -What motivates me is the combination of technical depth, product-level constraints, and user impact. I enjoy turning "this should be impossible" into something reliable enough to demonstrate and iterate. - -### 4. **Will you be working on GSoC full-time? In case not, what will you be studying or working on while working on the project?** - -Yes, full-time. GSoC is my main commitment during the coding period and I'm treating it that way. -I won't pretend I have zero going on, because I'm in college, I have side projects, and I've worked with clients. But honestly that's exactly why I'm not worried about this. Client work taught me that deadlines are real, communication matters, and you don't get to disappear when things get hard. I bring that same accountability here. I'll show up every week, flag blockers early, and I won't let review turnaround become a bottleneck on the mentor's end. - -### 5. **Do you mind regularly syncing up with the project mentors?** - -Not at all, I actually prefer it. I learned this the hard way with my first client. They were pretty quiet throughout the project, I kept building, and when I handed them the final product they said they didn't want it running on the PC itself, they wanted it on the cloud. Suddenly I'm dealing with containers, Kubernetes, deployment pipelines, things that weren't in the original plan at all. It took a lot of extra effort that could've been avoided with one conversation early on. -That experience genuinely changed how I work. Regular syncs aren't overhead to me anymore, they're how you avoid expensive surprises at the end. I'd rather flag a blocker or a design question on Monday than explain a derailed week on Friday. I'll bring progress openly, show what's working and what isn't, and if I'm choosing between two implementation approaches I'll bring both to the mentor instead of silently picking one. - -### 6. **What interests you the most about API Dash?** - -Honestly, I've felt the pain this tool is trying to solve. -When I was building **Aloo Bot**, backed by hundreds of different APIs, I wasn't even using proper tools. I had a Python script I'd manually modify every time I needed to test something different. Change the endpoint, change the payload, run it, check the output, repeat. For REST that was annoying. When I got into trading automation with Binance and Bybit, testing exchange APIs under real latency pressure with that same script was genuinely painful. Every test was a manual edit away and there was no visibility into what was actually happening on the wire. -API Dash is the tool I wished existed back then. It already has a solid cross-platform foundation and a clean architecture, it's not a toy, it's something developers actually use. And it's open source, which means when I add WebSocket, MQTT, and gRPC support, it's not a feature locked inside one company's product, it's available to every developer who's still out there editing Python scripts to test their APIs. -That's what interests me most. Not just the technical challenge, but the fact that shipping this actually makes something meaningfully better for people who build what I build. - -### 7. **Can you mention some areas where the project can be improved?** - -The obvious one is what this proposal is about, WebSocket, MQTT, and gRPC support. But a few things I noticed while actually working in the codebase: -Long-running sessions have almost no observability. If you're connected to a WebSocket for ten minutes and something goes wrong, there's not much to help you understand what happened, no message timeline metadata, no transport diagnostics, no way to replay the session. For debugging real production issues that's a real gap. -The history is useful but lightweight for protocol sessions. It shows that a request was made but not much about what the session looked like, how long it ran, how many messages exchanged, whether it disconnected cleanly. That context matters when you're debugging intermittent failures. -Contributor onboarding for protocol work is thin. The existing docs cover HTTP well but if someone wanted to add a new protocol or extend an existing one, there's not much guiding them through the provider/model/service pattern. That slows down community contributions. -And one small UX thing — advanced controls in the editor panes could be organized more consistently. Right now different panes handle progressive disclosure differently, which adds friction when you're switching between protocols. - -### 8. **Have you interacted with and helped API Dash community? (GitHub/Discord links)** - -Yes. I have interacted through issue-driven PR work and community contribution channels. - -I have actively worked on real issues, submitted PRs, and built idea/prototype artifacts specifically for API Dash’s GSoC direction. - -Recent PoC contribution evidence: - -- GSoC PoC PR: [#1473](https://github.com/foss42/apidash/pull/1473) - - Title: Add MQTT, WebSocket, and gRPC support to API Dash (PoC) - - Status: Open (from `alaotach:poc` to `foss42:main`) - - Scope: 14 commits, 57 files changed, +23,416 / -1,256 lines -- PoC demo video: [Google Drive demo](https://drive.google.com/file/d/1ufOMtceT_AyjXEdzWkwdhDEFOvwThADI/view?usp=sharing) - ---- - -### Project Proposal Information - -## Proposal Title - -**WebSocket, MQTT, and gRPC Support in API Dash** - -## Abstract - -API Dash is excellent for HTTP, but a large chunk of modern backend systems don't speak HTTP. WebSocket powers real-time dashboards and chat. MQTT runs IoT sensors and telemetry pipelines. gRPC connects microservices and ML infrastructure. Right now, developers testing these systems have to leave API Dash entirely and juggle separate tools, or do what I used to do, which is maintain a Python script they modify by hand every time. - -This project adds first-class support for all three protocols directly inside API Dash. Not as experimental add-ons as complete workflows with their own request models, connection state, message timelines, and debugging tools, built on the same provider/service/model architecture the codebase already uses for REST. - -By the end of GSoC, a developer should be able to open API Dash and: -- connect to a WebSocket endpoint, send and receive messages, and replay a session for debugging -- connect to an MQTT broker, publish and subscribe across topics with QoS controls -- invoke a gRPC method via server reflection without needing a `.proto` file on hand - -All of this while the existing HTTP workflows stay completely untouched and with production-grade UX patterns for reliability, observability, and reproducibility. - -3. **Detailed Description** - -![](https://github.com/foss42/apidash/assets/615622/493ce57f-06c3-4789-b7ae-9fa63bca8183) - -## 3.1 Problem Statement and Need - -Most backend systems today aren't pure REST. WebSocket handles real-time event streams and bidirectional channels. MQTT drives IoT telemetry and broker-mediated messaging. gRPC powers contract-first microservice communication. But API Dash currently has no support for any of them. - -That forces developers into a fragmented workflow, a different tool for each protocol, repeated environment setup, no shared history, and no way to reproduce a debugging session across systems. I know this firsthand because before I found proper tooling I was doing all of this with a Python script I'd manually edit every time I needed to test something different. - -This project closes that gap directly inside API Dash. One tool, all four protocols, the same UX. - -## 3.2 Existing Codebase Grounding - -Before writing any proposal I spent time actually reading the codebase to find where protocol support would need to plug in. Three files are the key extension points: - -- `packages/better_networking/lib/models/http_request_model.dart` — where the existing HTTP request model lives. New protocol models need to follow the same pattern rather than extending this one, which was the root cause of failure in previous MQTT and WebSocket PRs. -- `lib/screens/home_page/editor_pane/details_card/request_pane/request_pane.dart` — where API type switching decides which editor to render. This is where new protocol panes get routed in. -- `lib/providers/collection_providers.dart` — where `sendRequest()` orchestrates execution. This is where the protocol router hooks into the existing flow without breaking HTTP. - -I also searched all `APIType` switch callsites across the codebase to map every place that needs updating when a new protocol is added, not just the obvious ones. - -## 3.3 Proposed Architecture Extension - -The core decision here is to not touch the existing HTTP abstractions at all. Previous PRs that tried to reuse `HttpRequestModel` for WebSocket and MQTT ended up breaking things or losing state — the models have fundamentally different shapes and lifecycles. Each protocol gets its own dedicated model instead: - -- `WebSocketRequestModel` -- `MqttRequestModel` -- `GrpcRequestModel` - -Execution routes through a clean dispatch chain: -``` -RequestExecutor → ProtocolRouter → ProtocolHandler -``` - -HTTP hits the existing pipeline unchanged. Every new protocol hits its own handler, with its own state machine and validation logic, completely isolated from the others. - -Four design goals drove every decision here: - -- **Isolation** — protocol-specific state and validation lives in its own model, not bolted onto HTTP abstractions -- **Non-regression** — existing HTTP, REST, and GraphQL workflows are untouched by any of this -- **Incremental delivery** — the architecture slices cleanly into small PRs: routing baseline first, then one protocol at a time -- **Extensibility** — adding a fourth protocol in the future means adding a new handler, not rearchitecting the existing ones - -![](https://github.com/user-attachments/assets/c2933c78-806e-48c6-968e-36a3995bdef6) - -## 3.4 WebSocket Module - -The WebSocket module is the most complete of the three in the PoC. Here's what it covers: - -### 3.4.1 Transport and Connection Behavior - -- `ws://` and `wss://` support with TLS certificate introspection -- Custom headers and query parameters on the handshake request -- Explicit connection lifecycle — connecting, connected, reconnecting, disconnected, error each with appropriate controls enabled or disabled -- Reconnect policies with exponential backoff -- Keepalive with ping/pong visibility in the message timeline - -### 3.4.2 Message Handling - -- Send and receive text, JSON, and binary payloads -- Timeline view with sent/received direction indicators, sequence numbers, timestamps, and payload size -- Binary-safe rendering with configurable decoder (UTF-8, hex, base64) -- Search and filter across the message timeline - -### 3.4.3 Advanced Tooling - -- Decoder pipeline — upload a Protobuf descriptor, FlatBuffers schema, or Avro schema to decode binary messages automatically -- Session export and import in JSONL format for reproducible debugging -- Replay controls — replay sent-only or full session, with speed and jitter controls -- Transport diagnostics — TLS subject, issuer, fingerprint, validity window, frame-level metrics - -### 3.4.4 Persistence - -- Draft connection options saved with request state — reopening a request restores your last URL, headers, and settings -- Session metadata captured for history — duration, message count, connection status, error summary - -> All advanced tooling lives behind a toggle so the default view stays clean. - -## 3.5 MQTT Module - -### 3.5.1 Broker Connectivity - -- Broker host/port with TLS toggle (`mqtts://`) -- Client ID, username/password auth -- Connection status that actually tells you what went wrong, CONNACK return codes mapped to human-readable messages (identifier rejected, bad credentials, not authorized) instead of a generic "connection refused" -- Protocol version selector (3.1.1 / 5.0), keep-alive interval, and clean session controls -- Live status bar showing connection state, message counts, throughput, latency, and last message time at a glance - -### 3.5.2 Pub/Sub Workflows - -- Publish to any topic with QoS (0 at-most-once, 1 at-least-once, 2 exactly-once) and retain flag — with payload templates for quick JSON scaffolding -- Dynamic subscribe and unsubscribe — add topics with individual QoS levels, remove them without reconnecting, active subscriptions shown with live per-topic message rate -- Topic-filtered message stream on the right pane — filter by type (SUB/PUB), search by content, each message shows topic, payload, QoS badge, size, and timestamp -- "Use last sent" shortcut to quickly republish the previous payload - -### 3.5.3 Diagnostics and Replay - -- Live status strip — msgs/s, sent count, recv count, throughput in B/s, latency, connect attempts, time since last message -- Session export and import in JSONL format -- Deterministic replay with speed scaling and seeded jitter for reproducing timing-sensitive bugs -- All replay and advanced controls grouped behind an Advanced toggle to keep the default view clean - -### 3.5.4 Scope Note - -The primary target is a stable, reliable MQTT workflow — connect, publish, subscribe, debug, replay. Broker-specific edge cases and extended protocol tuning will be tracked as follow-up work after the core lands. - -## 3.6 gRPC Module - -### 3.6.1 Discovery and Schema Handling - -- **Reflection-first** — connect to any gRPC server with reflection enabled and the Service Explorer populates automatically. No `.proto` file needed. Services and methods browse instantly from the left panel. -- **`.pb` descriptor import** as fallback for production servers with reflection disabled, simpler and more reliable than maintaining a proto text parser -- Service/method tree maps directly to the request builder, selecting a method generates the correct form fields from the descriptor at runtime - -One non-obvious thing I ran into while building this: the reflection RPC itself is a bidi-streaming call. When it finishes and the stream closes, some servers respond with an HTTP/2 `GOAWAY` that kills the entire shared channel, so the actual RPC call right after reflection would fail with a connection error. The fix is a **separate ephemeral channel** for reflection only, shut down cleanly after discovery, then a fresh channel for real calls. That's now baked into the architecture. - -### 3.6.2 Invocation Workflows - -- Connection target with TLS toggle and metadata (gRPC headers) per call -- Request builder in two modes — **Form Mode** (typed fields generated from the descriptor, - with correct input types for string/bool/enum/bytes/nested messages) and **JSON Mode** for - power users -- All four call types supported: Unary, Server Streaming, Client Streaming, Bidirectional -- Response pane shows body, headers, trailers, and a timeline — each streaming message - rendered as a separate timestamped card -- Invoke gating — the Invoke button stays disabled until both connection and descriptor are - ready, preventing invalid execution states - -### 3.6.3 Encoding/Decoding Strategy - -No generated stubs — API Dash doesn't have compiled `.proto` files at runtime. The dynamic encoder handles all 15 protobuf field types directly from the descriptor: - -- **Varints** (wire type 0): int32, uint32, sint32/64 with ZigZag, bool, enum -- **Fixed-width** (wire types 1 & 5): float, double, fixed32/64, sfixed32/64 -- **Length-delimited** (wire type 2): string, bytes, nested messages - -Wire type correctness matters here — a wrong wire type corrupts the length prefix and every field after it becomes garbage. The encoder writes raw `ByteData` directly rather than trying to use the `protobuf` package's `CodedBufferWriter` (which is designed for generated code, not dynamic use). - ---- - -## 3.7 ConnectRPC Direction (Stretch) - -ConnectRPC support is a stretch goal, explicitly deferred until core protocol stability lands. The approach would layer through existing HTTP service primitives with protocol-specific envelope and header handling, reusing the gRPC editor path. If core delivery finishes ahead of schedule this gets picked up, otherwise it becomes a post-GSoC follow-up PR. - ---- - -## 3.8 UI/UX Integration Plan - -All three protocol panes follow the same conventions API Dash already uses: - -- **Compact default surface** — the view you see on open shows only what you need to make a - connection and send a message -- **Advanced options behind toggles** — replay controls, decoder uploads, diagnostics, - extended settings all hidden until you need them -- **Timeline/log first** — the response pane leads with the message stream, not metadata -- **Safe state transitions** — controls enable and disable based on connection state. - You can't send before connecting, can't subscribe before the broker confirms, can't invoke - before the descriptor is loaded -- **Consistent across protocols** — same connect/send/log/replay pattern on every pane so - switching protocols doesn't require relearning the UI - -### MQTT Pane - -Three-panel layout — connection and topics on the left, publish controls in the center, live message stream on the right. The status bar across the top shows connection state, message counts, throughput, and latency at all times so you never have to dig for it. Advanced replay, import/export, and extended broker settings live behind an Advanced toggle and don't clutter the default view. - -### WebSocket Pane - -URL bar at the top, message timeline in the center, send box at the bottom — the same mental model as a chat client because that's what makes sense for a bidirectional stream. Sent and received messages are visually distinct. Filters and search sit above the timeline. Transport diagnostics (TLS cert info, frame metrics, sequence gaps) and decoder/replay controls are behind a Hide/Show advanced toggle so they're one click away but not always in your face. - -### gRPC Pane - -Service Explorer on the left for browsing discovered services and methods. Request Builder in the center with Form Mode and JSON Mode, generated directly from the runtime descriptor. Response pane on the right showing body, headers, trailers, and a per-message timeline for streaming calls. Reflection and `.pb` import controls are in the Service Explorer panel — where you'd naturally look when setting up a connection, not buried in settings. - -## 3.9 History and Persistence Strategy - -HTTP requests have a clean request/response pair, easy to store. Protocol sessions don't. A WebSocket session might run for twenty minutes and exchange thousands of messages. Storing everything by default would bloat history fast and make it unusable. - -The approach is lightweight summary metadata per session: - -- session duration -- message counts (sent/received) -- final connection status -- error summary if it ended badly -- reference to the exported JSONL file if the session was explicitly saved for replay - -Full payload history is opt-in via export, not automatic. This keeps the history sidebar useful, you can see at a glance what happened in a session without loading the entire message log, and lets users decide for themselves when a session is worth keeping in full. - -Draft connection options (URL, headers, broker settings, last payload) are persisted with the request state so reopening a request puts you back where you were. - -## 3.10 Testing Strategy - -Testing is staged by milestone — unit tests land with each feature PR, not saved for the end. The goal is to catch regressions at the PR level, not during a final stabilization sprint. - -### Unit Tests - -The boring but essential layer — protocol models, parser/serializer transforms, provider state transitions, and invalid-input handling. These run fast and catch the class of bugs that are hardest to spot in a running app: wrong field defaults, serialization edge cases, state machine transitions that skip a step. - -### Widget Tests - -Pane-level interactions — connect button enables and disables at the right times, advanced panel shows and hides correctly, inline validation errors appear and clear on user input, disabled states actually prevent actions. These exist because a lot of subtle UX bugs only show up when you simulate real interaction sequences. - -### Integration Tests - -End-to-end flows against real test servers: -- WebSocket echo endpoints for send/receive round-trips and reconnect behavior -- Public MQTT test brokers (broker.hivemq.com) for publish/subscribe workflows -- gRPC sample services (grpcb.in) for both reflection-enabled and descriptor-import paths - -### Regression Safety - -Every protocol PR runs the existing REST, GraphQL, and AI workflow tests before merge. Editor switching and history behavior get explicit checks — these are the two surfaces most likely to silently break when new protocol routing is added. - -## 3.11 Reliability and Risk Management - -Four risks worth being honest about upfront, and what I'm doing about each: - -**1. Transport edge cases** -WebSocket fragmentation, MQTT broker quirks, gRPC servers that send `GOAWAY` after reflection — these don't show up in happy-path testing. Mitigation is staged rollout with protocol-specific diagnostics built in from day one, not added later. If something breaks silently, the diagnostics surface should tell you where. - -**2. UI complexity growth** -Three new protocol panes is a lot of surface area. The risk is that each one slowly accumulates controls until the default view is overwhelming. Mitigation is the Advanced toggle pattern applied consistently — high-frequency controls always visible, everything else hidden until needed. This is enforced at the design level, not just aspirationally. - -**3. State migration and regression risk** -Adding new fields to protocol models means older persisted sessions might be missing those fields on load. I hit this during PoC development — hot reload would create stale state objects that crashed on newly added non-null fields. Mitigation is defensive defaults everywhere: nullable counters with `?? 0` fallbacks, backward-safe model evolution, and migration checks before each protocol merge. - -**4. Over-scoping** -Three protocols in twelve weeks is ambitious. The risk is trying to do too much on each and shipping none of them properly. Mitigation is a hard core/stretch boundary — unary gRPC before streaming, stable MQTT before MQTT v5, working WebSocket before advanced decoder pipelines. Stretch items are real planned work, not vague aspirations, but they don't block core delivery. - -### 3.11.1 Feature and Implementation Tradeoffs - -This project is intentionally designed around explicit tradeoffs so the implementation stays practical, reviewable, and shippable within GSoC timelines. - -1. **Breadth (3 protocols) vs depth (one protocol with many advanced features)** - - Decision: deliver production-usable core workflows for WebSocket, MQTT, and gRPC first. - - Benefit: API Dash becomes a true multi-protocol client. - - Tradeoff: some advanced features (for example, richer codec/plugin pipelines or expanded gRPC streaming helpers) may remain stretch items. - -2. **Stable UX consistency vs protocol-specific flexibility** - - Decision: keep pane structure and controls consistent across protocols (connect/send/log/replay), while exposing protocol-specific controls in advanced sections. - - Benefit: lower user learning curve and easier maintenance. - - Tradeoff: protocol power users may need one extra click for advanced controls. - -3. **Compact default UI vs feature discoverability** - - Decision: place heavy options (codec uploads, replay controls, import/export, extended MQTT settings) behind Advanced toggles. - - Benefit: avoids editor clutter and layout instability. - - Tradeoff: discoverability of advanced capabilities is slightly reduced; mitigated with labels/tooltips and docs. - -4. **WebSocket low-level diagnostics vs implementation complexity** - - Decision: retain useful transport/TLS diagnostics and sequence tracking in service/provider layers. - - Benefit: better debugging for real production socket issues. - - Tradeoff: service internals become more complex and require stronger test coverage and refactoring discipline. - -5. **MQTT operational completeness vs initial simplicity** - - Decision: prioritize practical MQTT session flows (connect/publish/subscribe/unsubscribe/history/replay) over broker-specific edge-case tuning. - - Benefit: reliable day-to-day MQTT usage lands sooner. - - Tradeoff: some specialized broker behaviors and performance tuning knobs are deferred. - -6. **gRPC reflection-first onboarding vs guaranteed compatibility** - - Decision: support reflection and descriptor-driven workflows in a single editor path. - - Benefit: easier service exploration and method discovery for most users. - - Tradeoff: reflection-disabled environments need stronger manual descriptor handling and validation paths. - -7. **Replay fidelity vs storage/runtime cost** - - Decision: persist protocol events and support JSONL import/export for reproducible replay. - - Benefit: deterministic debugging and sharable sessions. - - Tradeoff: larger histories increase disk usage and replay orchestration complexity; mitigated by filtering and bounded retention defaults. - -8. **Strong model typing vs migration effort** - - Decision: extend protocol request/session models explicitly instead of loosely typed payload blobs. - - Benefit: safer state transitions and easier long-term maintainability. - - Tradeoff: migration/model-update overhead increases in the short term. - -9. **Delivery speed vs test depth** - - Decision: stage tests by milestone (unit -> widget -> integration) and enforce regression checks before each protocol merge. - - Benefit: better release confidence and lower regression risk. - - Tradeoff: slower short-term iteration during feature spikes. - -10. **Ambitious scope vs predictable execution** - - Decision: keep strict core/stretches boundaries and publish milestone-level acceptance criteria. - - Benefit: mentors can evaluate progress objectively and unblock quickly. - - Tradeoff: attractive but non-critical enhancements may be postponed to post-GSoC follow-up PRs. - -## 3.12 Deliverables Summary - -**Core** -1.

- native reflection imports and descriptor graph processing - - descriptor cache keyed by endpoint - - reflection-first discovery with proto-upload-required fallback - -### 3.14.4 How the PoC Was Built (Implementation Phases) - -#### Phase 1: Protocol editor scaffolding and routing integration - -- Added protocol-specific panes and base provider/service hooks. -- Established state-machine style session structures so each protocol could evolve independently. -- Ensured API type switching could route to dedicated protocol workflows. - -#### Phase 2: WebSocket depth-first implementation - -- Implemented message timeline and connection controls first. -- Added advanced tooling (decoder upload/plugin hooks, JSONL import/export, replay). -- Expanded into low-level transport diagnostics (TLS metadata, frame-level metrics, fragmentation/compression counters). - -#### Phase 3: MQTT feature parity and replay tooling - -- Implemented broker connect/publish/subscribe flow. -- Added telemetry strips and rolling rate calculations. -- Added replay/import/export controls with pause/resume/speed/jitter. -- Aligned advanced panel behavior with WebSocket for UI consistency. - -#### Phase 4: gRPC discovery and invocation path hardening - -- Reflection-first discovery path. -- Descriptor fallback handling in UI flow. -- Metadata controls and invoke gating to avoid invalid execution states. - -#### Phase 5: Runtime stabilization and regression hardening - -- Fixed compile-time model generation mismatches. -- Fixed runtime hot-reload and provider state migration issues. -- Fixed narrow-pane overflow and advanced-control layout collisions. - -### 3.14.5 Concrete Problems Encountered While Building and How They Were Fixed - -#### Problem 1: Freezed/model mismatch after adding protocol-related fields - -- **Symptom:** compile errors in history/request model implementations after field changes. -- **Root cause:** Freezed class declarations and generated artifacts became inconsistent during model evolution. -- **Fix:** converted affected models to proper abstract + mixin style and regenerated code. -- **Result:** generated code aligned; compile errors cleared. - -#### Problem 2: WebSocket subscription type crash at runtime during dispose - -- **Symptom:** runtime type error similar to `_ControllerSubscription` not matching expected typed subscription during disposal. -- **Root cause:** overly specific subscription field generic did not match runtime stream subscription type in low-level flow. -- **Fix:** relaxed internal subscription field type to avoid runtime cast trap and keep disposal safe. -- **Files touched:** WebSocket service layer. - -#### Problem 3: MQTT null subtype crashes after hot reload - -- **Symptom:** nullable/runtime subtype failures in metrics widgets when reading newly introduced non-null counters. -- **Root cause:** hot-reload/session migration path created older state objects lacking newly added fields. -- **Fix:** defensive nullable counter strategy with `?? 0` fallback in state copy/update math and UI derived values. -- **Files touched:** MQTT provider + MQTT metrics UI. - -#### Problem 4: MQTT stream pane RenderFlex overflow - -- **Symptom:** overflow in narrow pane due to replay control rows. -- **Root cause:** fixed-width row layout in constrained width. -- **Fix:** changed controls to wrapping/adaptive layout and moved advanced controls behind a toggle panel. -- **Result:** compact default UI and no overflow under narrow constraints. - -#### Problem 5: Advanced controls consuming too much editor space - -- **Symptom:** replay/import/export controls crowded primary pane. -- **Root cause:** controls were always visible in stream panel. -- **Fix:** adopted WebSocket-style advanced toggle pattern for MQTT (`Advanced` / `Hide advanced`) and conditional panel rendering. - -#### Problem 6: WebSocket low-level diagnostics compile/runtime edge cases - -- **Symptom:** compile errors around const usage/type conversion/decode arguments during deep transport rewrite. -- **Root cause:** API signature and typing mismatches while replacing high-level channel behavior with low-level socket flow. -- **Fix:** iterative compile error resolution and validation; normalized type conversions for diagnostics outputs. - -### 3.14.6 Representative Technical Patterns Implemented - -#### Pattern A: Defensive state evolution for runtime-safe hot reload - -- Nullable counters in session state where backward compatibility is needed. -- Provider update paths convert null legacy values into deterministic defaults. - -#### Pattern B: Replay engine controls for reproducible debugging - -- Imported session log converted into replay entries. -- Replay state machine includes: - - run token, - - progress index/total, - - pause/resume, - - speed scaling, - - seeded jitter for deterministic delay perturbation. - -#### Pattern C: Advanced tooling ergonomics - -- Keep high-frequency controls in primary pane. -- Move low-frequency diagnostic/replay operations into advanced toggles. -- Preserve one-click visibility while minimizing persistent visual noise. - -### 3.14.7 Why the PoC Diff Became Very Large and How Productionization Will Be Controlled - -The PoC was intentionally exploratory — three protocols in parallel, runtime failures to debug, architecture decisions to validate. A 24k-line diff is the right output for that phase. It would be the wrong way to merge it. - -Productionization happens in 8 focused PRs: - -1. Model and routing baseline -2. WebSocket core -3. WebSocket advanced diagnostics/replay -4. MQTT core -5. MQTT advanced/replay -6. gRPC discovery/invoke -7. Persistence/history -8. Stabilization + tests - -Each PR is reviewable on its own. No reviewer overload, no big-bang merge risk. - -### 3.14.8 Additional Technical References - -Primary proposal and idea grounding files: - -- `doc/proposals/2026/gsoc/idea_alaotach_grPC_MQTT_Websocket_Integration.md` -- `doc/proposals/2026/gsoc/application_aryan_mishra_multi_protocol_support.md` -

-## 3.15 PoC Completion Gap: What Is Not Done Yet and What Will Be Done During GSoC - -This subsection explicitly captures the gap between the current PoC state and the final production-quality deliverables planned for GSoC. - -### 3.15.1 What is not fully done in the PoC yet - -1. **Production PR slicing is incomplete** - - Current PoC evolved as a large exploratory branch and still needs to be split into tightly scoped, review-friendly pull requests. - -2. **Automated test coverage is not complete for all protocol paths** - - Core runtime behavior was validated through iterative manual testing and diagnostics. - - Full unit/widget/integration coverage for all newly added protocol interactions is still pending. - -3. **gRPC deep streaming maturity is not fully complete** - - Unary and primary invocation paths are the focus of current stability. - - Client-streaming and bidirectional-streaming require dedicated production hardening and broader test fixtures. - -4. **ConnectRPC path is not completed** - - It is designed as a stretch direction and intentionally deferred until core protocol stability lands. - -5. **Long-run stress and soak reliability testing is pending** - - Reconnect loops, long session replay, and high-volume message streams still require systematic stress benchmarks. - -6. **Final documentation package is not complete yet** - - User guides, developer extension notes, and protocol troubleshooting docs must be completed to production quality. - -7. **Compatibility/migration hardening for all persisted states is not finished** - - Additional backward-compatibility checks for older stored sessions and metadata are planned. - -### 3.15.2 What will be done during GSoC to close the gap - -1. **Convert monolithic PoC into structured milestone PRs** - - Router/model baseline PR. - - WebSocket core PR. - - WebSocket diagnostics/replay PR. - - MQTT core PR. - - MQTT advanced/replay PR. - - gRPC discovery/invoke PR. - - Persistence/history PR. - - Stabilization/tests/documentation PR. - -2. **Complete protocol-specific automated testing matrix** - - Unit tests for request models, provider state transitions, validation guards, and serialization behavior. - - Widget tests for pane controls, advanced toggles, disabled states, and error rendering. - - Integration tests against WebSocket echo endpoints, MQTT brokers, and gRPC discovery/invoke scenarios. - -3. **Finalize gRPC roadmap incrementally** -

-Refactoring the current PoC code is an explicit GSoC task, not an optional cleanup pass. The goal is to preserve feature behavior while improving maintainability, testability, and long-term contributor velocity. - -#### Refactoring objectives - -1. Reduce monolithic service/provider/widget methods into composable units. -2. Isolate protocol business logic from UI rendering code. -3. Standardize session state transitions across WebSocket, MQTT, and gRPC. -4. Improve naming consistency, error surface clarity, and diagnostics boundaries. -5. Make critical flows easier to unit test without relying on full UI integration paths. - -#### Planned refactoring scope - -1. **WebSocket service and provider decomposition** - - Split connection lifecycle, telemetry updates, and message dispatch into dedicated helpers. - - Keep transport diagnostics handling in a dedicated diagnostics path to reduce coupling with send/receive logic. - -2. **MQTT provider and pane separation of concerns** - - Move replay/import/export orchestration out of large widget-state methods into focused controller/service utilities. - - Keep UI state minimal and delegate protocol actions to testable provider/controller layers. - -3. **gRPC editor execution path cleanup** - - Separate discovery/descriptor resolution from invocation execution flow. - - Keep request shaping, invocation, and response rendering as explicit pipeline stages. - -4. **Cross-protocol consistency layer** - - Align lifecycle state naming and transition semantics across protocol providers. - - Introduce shared patterns for connection status, error reporting, and replay metadata handling where appropriate. - -#### Execution approach - -1. Refactor in small PRs with no intentional behavior change. -2. Add or update tests before and after each refactor slice to validate parity. -3. Use milestone-level checklists to confirm no UX regressions in protocol panes. -4. Keep each refactor PR scoped to one primary surface (service, provider, or UI pane) for reviewer clarity. - -#### Measurable outcomes - -1. Reduced method/class complexity in the largest protocol surfaces. -2. Increased unit-testable logic outside widget state classes. -3. Clearer ownership boundaries between protocol transport, state orchestration, and UI layers. -4. Lower review friction for follow-up feature PRs due to cleaner architecture. - -### 3.15.4 Definition of done for production completion - -The protocol work will be considered production-ready only when all of the following are true: - -1. Each protocol has stable connect, send, receive, and disconnect behavior. -2. Advanced tooling (replay/import/export/diagnostics) is usable without layout instability. -3. Automated tests cover core and edge-case state transitions. -4. Existing REST/GraphQL/AI flows remain regression-free. -5. Documentation and demo artifacts are complete and reproducible. -6. Refactoring milestones are completed for major protocol surfaces with behavior parity validated by tests. - -## 3.16 Technical Implementation Blueprint (Code-Level Proposal) - -This section provides code-level architecture sketches to make implementation intent explicit and reviewable. - -### 3.16.1 Protocol request contracts - -```dart -enum ProtocolType { http, websocket, mqtt, grpc } - -abstract class ProtocolRequestModel { - ProtocolType get protocol; - String get requestId; - Map toJson(); - List validate(); -} - -class WebSocketRequestModel implements ProtocolRequestModel { - @override - final ProtocolType protocol = ProtocolType.websocket; - - @override - final String requestId; - - final Uri endpoint; - final Map headers; - final List subprotocols; - final bool autoReconnect; - final int keepAliveSec; - - WebSocketRequestModel({ - required this.requestId, - required this.endpoint, - this.headers = const {}, - this.subprotocols = const [], - this.autoReconnect = false, - this.keepAliveSec = 0, - }); - - @override - List validate() { - final errors = []; - if (!endpoint.isScheme('ws') && !endpoint.isScheme('wss')) { - errors.add('Endpoint must use ws:// or wss://'); - } - if (keepAliveSec < 0) { - errors.add('keepAliveSec cannot be negative'); - } - return errors; - } - - @override - Map toJson() => { - 'requestId': requestId, - 'endpoint': endpoint.toString(), - 'headers': headers, - 'subprotocols': subprotocols, - 'autoReconnect': autoReconnect, - 'keepAliveSec': keepAliveSec, - }; -} -``` - -### 3.16.2 Protocol router and execution dispatcher - -```dart -abstract class ProtocolHandler { - Future connect(T model); - Future disconnect(String requestId); - Stream events(String requestId); -} - -class ProtocolRouter { - ProtocolRouter({ - required this.wsHandler, - required this.mqttHandler, - required this.grpcHandler, - }); - - final WebSocketHandler wsHandler; - final MqttHandler mqttHandler; - final GrpcHandler grpcHandler; - - Future execute(ProtocolRequestModel model) async { - switch (model.protocol) { - case ProtocolType.websocket: - await wsHandler.connect(model as WebSocketRequestModel); - case ProtocolType.mqtt: - await mqttHandler.connect(model as MqttRequestModel); - case ProtocolType.grpc: - await grpcHandler.connect(model as GrpcRequestModel); - case ProtocolType.http: - throw UnsupportedError('HTTP handled by existing pipeline'); - } - } -} -``` - -### 3.16.3 WebSocket core implementation (handshake + framing + control frames) - -```dart -class WebSocketTransportCore { - Socket? _socket; - StreamSubscription? _subscription; - final BytesBuilder _rxBuffer = BytesBuilder(copy: false); - final BytesBuilder _fragmentBuffer = BytesBuilder(copy: false); - int? _fragmentOpcode; - - final _events = StreamController.broadcast(); - Stream get events => _events.stream; - - Future connect(WebSocketRequestModel model) async { - final port = model.endpoint.hasPort - ? model.endpoint.port - : (model.endpoint.scheme == 'wss' ? 443 : 80); - - _socket = model.endpoint.scheme == 'wss' - ? await SecureSocket.connect(model.endpoint.host, port) - : await Socket.connect(model.endpoint.host, port); - - await _upgradeHandshake(model); - - _subscription = _socket!.listen( - _onSocketChunk, - onDone: () => _events.add(WsDisconnected()), - onError: (e, st) => _events.add(WsError(e.toString())), - ); - } - - Future _upgradeHandshake(WebSocketRequestModel model) async { - final nonce = base64.encode( - List.generate(16, (_) => Random.secure().nextInt(256)), - ); - - final path = (model.endpoint.path.isEmpty ?

Keep deployments reproducible through containerization and CI - -### 3.2 Technology stack - -- Frontend: Next.js 14 (App Router), TypeScript, TanStack Query, React Hook Form, Zod -- Backend: FastAPI, SQLAlchemy 2.x, Pydantic, Alembic -- Async tasks: ARQ + Redis for async ingestion workers and progress updates -- Database: PostgreSQL as system of record, with optional Apache AGE extension for graph traversals -- File/object storage: MinIO (S3-compatible) for raw uploads and import artifacts -- Auth: Logto (OIDC/OAuth2) for admin/curator/public role flows -- Containerization: Docker Compose for development and reproducible CI -- Deployment target: Coolify (self-hosted PaaS style deployment), with cloud migration path later -- CI: GitHub Actions for lint, type checks, test matrix, and image build smoke checks - -### 3.3 Database strategy: PostgreSQL first, Neo4j only if required - -I am intentionally proposing PostgreSQL as the single primary database to minimize operational complexity and maximize delivery confidence in GSoC timelines. - -- Core plan: relational model + indexed query paths in PostgreSQL -- Graph query plan: optional Apache AGE for openCypher-like traversal on the same database -- Neo4j position: not core for v1 delivery; evaluate only if profiling shows repeated multi-hop graph traversals over very large interaction graphs that cannot meet latency targets in PostgreSQL/AGE - -This keeps backup, migration, and contributor setup simple while preserving a clear path to a dedicated graph database if needed. - -### 3.4 Service boundaries - -- API Gateway Layer: auth, request validation, pagination, filtering -- Upload Service: file intake, checksum, storage abstraction, job enqueue -- Parser Service: PSI-MI TAB parser, CSV parser, validation contracts -- Interaction Service: normalized interaction model orchestration -- Annotation Service: molecule metadata enrichment from public sources -- Export Service: PSI-MI TAB and CSV exports from canonical normalized records -- Search Service: interaction graph retrieval and aggregated query responses - ---- - -## 4. Data Model and Ingestion Design - -### 4.1 Canonical normalized model - -A canonical interaction record will decouple storage from file format specifics. - -High-level entities: - -- Molecule (protein/gene/entity abstraction) -- Interaction -- InteractionEvidence -- Dataset -- Annotation -- SourceRecord (raw row provenance) -- UploadJob and UploadJobRowError - -This preserves existing concepts from [openpip.sql](openpip.sql#L296) and [openpip.sql](openpip.sql#L418), but adds explicit provenance and validation traces per ingested row. - -### 4.2 Multi-format parser contract - -Parser plugin interface (conceptual): - -- sniff(file) -> confidence -- parse(stream) -> iterator of RawInteractionRecord -- validate(record) -> list of structured validation errors -- transform(record) -> CanonicalInteraction - -Initial parsers: - -- PsiMiTabParser for PSI-MI TAB -- CsvInteractionParser for curated CSV schema - -### 4.3 Validation strategy - -- Schema validation: required columns, delimiter checks, encoding checks -- Domain validation: valid interactor identifiers, taxon constraints, score normalization -- Referential validation: dataset and annotation type consistency -- Duplicate and conflict handling: hash-based dedupe plus pair-key conflict resolution - -### 4.4 Row-level error UX - -Every failed row gets: - -- row index -- error code -- human-readable explanation -- remediation hint - -This enables practical correction workflows without opaque import failures. - ---- - -## 5. Upload/Admin Experience Redesign - -### 5.1 Admin upload workflow - -The new interface will replace legacy endpoint-centric flow in [src/AppBundle/Controller/DropzoneController.php](src/AppBundle/Controller/DropzoneController.php#L42) with a job-oriented pipeline: - -1. User drags one or many files into uploader -2. Client performs immediate preflight checks (size, extension, delimiter sampling) -3. Backend creates UploadJob, returns job id -4. Worker parses and validates asynchronously -5. UI subscribes to progress updates and displays row-level diagnostics -6. User can accept partial import, download error report, or retry corrected file - -### 5.2 UX details - -- Bulk upload queue with per-file status -- Live progress bars with stage states: queued, parsing, validating, writing, completed, failed -- Error panel with filter/search by code and row index -- "Download error report" as CSV/JSON -- "Re-run with updated mapping" for CSV column mapping mistakes - -### 5.3 Admin controls - -- Dataset metadata management -- Annotation type mapping rules -- Controlled vocab mapping for interaction methods and evidence -- Audit trail for uploads and user actions - ---- - -## 6. Metadata and Annotation Enrichment - -### 6.1 Target capability - -Support importing molecule metadata from public resources (for example UniProt/NCBI-derived identifiers and labels), attached as versioned annotations. - -### 6.2 Enrichment architecture - -- EnrichmentAdapter interface per provider -- Cached lookup table with TTL and provenance columns -- Rate-limited background enrichment jobs -- Validation to prevent stale/unknown identifier attachment - -### 6.3 Safety and reproducibility - -- Store source, fetch timestamp, and version snapshot on each annotation -- Support re-enrichment under explicit user action, not silent mutation - ---- - -## 7. API and Frontend Contract - -### 7.1 API groups - -- Upload APIs: create job, append file, fetch progress, fetch row errors, approve commit -- Interaction APIs: query by molecule, dataset, evidence, status -- Export APIs: PSI-MI TAB export, CSV export, filtered exports -- Metadata APIs: annotation types, enrichment status, mapping dictionaries -- Admin APIs: dataset and portal configuration management - -### 7.2 Frontend panes - -- Upload Manager -- Dataset Manager -- Search and Results Visualization -- Interaction Detail Drawer -- Export Panel -- Admin Settings - -### 7.3 Graph rendering strategy on the website - -For PPI network rendering, the primary library will be Cytoscape.js (not D3.js by default): - -- Cytoscape.js role: interaction network visualization, node/edge styling, filtering, selection, and layout operations suitable for biological graphs -- D3.js role: optional custom charts (for example upload quality histograms, score distributions, or dataset summary plots), not the primary interaction graph engine -- React Flow role: admin-only workflow views (for ingestion pipeline stages, job states, and provenance flow), separate from biological network rendering - -This separation avoids overengineering and picks each library for what it does best. - -### 7.4 Search modernization - -Legacy behavior in [src/AppBundle/Controller/SearchController.php](src/AppBundle/Controller/SearchController.php#L43) will be reimplemented as API-first composition: - -- Query parser in backend service -- Typed API response for proteins/interactions graph payload -- Frontend-only rendering concerns in React - -This removes mixed rendering/data logic currently visible in [src/AppBundle/Controller/SearchController.php](src/AppBundle/Controller/SearchController.php#L114). - ---- - -## 8. Migration Plan from Legacy to openPIP 2.0 - -### 8.1 Migration principles - -- Do not big-bang switch without data parity checks -- Build ingestion and query parity harness first -- Maintain reproducible migration scripts and checksums - -### 8.2 Incremental migration steps - -1. Build canonical schema and migration scripts -2. Import existing SQL snapshot from [openpip.sql](openpip.sql#L1) -3. Backfill canonical model from legacy entities -4. Run parity checks for key queries and export counts -5. Enable dual-run verification on representative datasets -6. Cut over UI and API once parity thresholds pass - -### 8.3 Data parity checks - -- Total proteins count -- Total interactions count -- Query response equivalence for known test terms -- Export row counts for PSI-MI TAB and CSV - ---- - -## 9. Containerization and DevOps Plan - -### 9.1 Why change - -Current deployment references older runtime baselines in [Docker OpenPIP package/Dockerfile](Docker%20OpenPIP%20package/Dockerfile#L1). openPIP 2.0 will use dedicated API/worker/frontend containers with explicit health checks and CI verification. - -### 9.2 New compose topology - -- frontend: Next.js app -- api: FastAPI app -- worker: ARQ worker -- redis: task broker -- postgres: main database -- minio: object storage for uploads - -### 9.3 CI pipeline - -- backend lint and type checks -- frontend lint and type checks -- unit tests -- integration tests with ephemeral postgres/redis -- container build validation - ---- - -## 10. Testing Strategy - -### 10.1 Unit tests - -- Parser unit tests (PSI-MI TAB and CSV) -- Domain validator unit tests -- Service-level dedupe/conflict resolution tests -- Annotation mapper tests - -### 10.2 Integration tests - -- Upload job full lifecycle -- Parser-to-db persistence flow -- Search endpoint response contracts -- Export correctness tests - -### 10.3 Regression and data-quality tests - -- Golden datasets with expected interaction counts -- Snapshot tests for normalized output records -- Round-trip tests: import -> canonical -> export - -### 10.4 Frontend tests - -- Component tests for upload queue and progress states -- Interaction/result panel rendering -- Error table filtering and remediation flows - ---- - -## 11. Risks and Mitigation - -1. Data model mismatches between PSI-MI TAB and CSV -- Mitigation: canonical transform layer with explicit provenance and per-format adapters - -2. Large file ingestion performance bottlenecks -- Mitigation: chunked streaming parser, async jobs, batched writes, indexes - -3. Graph query complexity may exceed relational query performance -- Mitigation: start with PostgreSQL indexes/materialized views, then enable Apache AGE for targeted traversals; evaluate Neo4j only if measured latency targets remain unmet - -4. Migration regressions -- Mitigation: parity harness, dual-run verification, staged cutover - -5. Scope pressure in 12 weeks -- Mitigation: strict core-vs-stretch boundaries, milestone acceptance gates - -## 11.1 Explicit Non-Goals for Core Timeline - -To keep the core delivery credible within GSoC, the following are intentionally out of core scope unless earlier milestones complete ahead of schedule: - -1. Full multi-hop graph analytics engine with custom query language surface -2. Neo4j as a required production dependency -3. Broad metadata federation across many remote providers in core timeline -4. Complex workflow orchestration beyond ingestion and validation jobs -5. Deep visual analytics dashboards beyond core exploration and export workflows - ---- - -## 12. Deliverables - -### 12.1 Core deliverables - -1. Backend scaffold with typed APIs -- Acceptance criteria: `/health`, `/uploads/jobs`, `/uploads/jobs/{id}`, `/interactions/search`, and export endpoints are implemented and covered by integration tests; OpenAPI docs generated in CI. - -2. Upload/admin interface with drag-drop and progress telemetry -- Acceptance criteria: multi-file upload queue supports at least 3 concurrent files; each file exposes stage states (`queued/parsing/validating/writing/completed/failed`) and downloadable row-error report. - -3. PSI-MI TAB parser (production-ready) -- Acceptance criteria: parser supports MITAB 2.5/2.6 core 15 columns, handles `|` multi-value fields, stores normalized interactors/evidence, and imports a 100k-row benchmark file with resumable progress tracking. - -4. CSV parser with explicit column mapping -- Acceptance criteria: curated CSV template + user mapping UI; validation catches missing mandatory columns and bad identifier patterns; mapped import path writes to same canonical schema as PSI-MI. - -5. Canonical interaction model with provenance tracking -- Acceptance criteria: each imported interaction links to `dataset_id`, `source_file`, `source_row`, `parser_version`, and row-level validation status; duplicate detection uses deterministic pair/evidence hash. - -6. Export module for PSI-MI TAB and CSV -- Acceptance criteria: filtered exports match canonical query results; parity tests verify row counts and mandatory column coverage against golden fixtures. - -7. Containerized development + CI pipeline -- Acceptance criteria: one-command local startup for frontend/api/worker/postgres/redis/minio; CI runs lint, type-check, unit/integration tests, and container build smoke tests. - -8. Website graph visualization for PPI exploration -- Acceptance criteria: Cytoscape.js view supports pan/zoom, layout switch, edge filtering by dataset/evidence/status, node search, and export of current subgraph selection. - -9. Documentation and contributor onboarding -- Acceptance criteria: setup docs, architecture notes, parser-extension guide, and troubleshooting page for failed imports are complete and reproducible on a clean machine. - -### 12.2 Stretch deliverables - -1. Additional file formats beyond initial CSV schema -2. Advanced molecule metadata enrichment source federation -3. Performance dashboard for ingestion metrics -4. Neo4j adapter (only if profiling demonstrates PostgreSQL/AGE limits) - ---- - -## 13.

Why Me and Execution Confidence - -I can execute this project because the work aligns with the exact kind of engineering this rewrite needs: - -- Converting monolithic request-layer logic into explicit service boundaries -- Designing parser pipelines that support multiple formats while preserving strict validation -- Building modern admin UIs with clear error states and operational observability -- Delivering in iterative, reviewable milestones instead of big-bang PRs - -I have already grounded this proposal in concrete openPIP code surfaces, including ingestion, export, routing, schema, and deployment references: - -- [src/AppBundle/Controller/DataController.php](src/AppBundle/Controller/DataController.php#L103) -- [src/AppBundle/Controller/DropzoneController.php](src/AppBundle/Controller/DropzoneController.php#L42) -- [src/AppBundle/Controller/DataDownloadController.php](src/AppBundle/Controller/DataDownloadController.php#L193) -- [src/AppBundle/Controller/SearchController.php](src/AppBundle/Controller/SearchController.php#L43) -- [openpip.sql](openpip.sql#L296) -- [Docker OpenPIP package/docker-compose.yml](Docker%20OpenPIP%20package/docker-compose.yml#L8) - -This gives a practical and low-risk path from proposal to implementation. - ---- - -## 15.

async Postgres writes for valid rows -- row-level error storage and retrieval -- **two-phase flow** (validate then commit) - -## Advanced Features Demonstrated - -### Two-Phase Ingestion Flow (Section 4.1) - -**uploaded → Phase 1: validate (parse + check) → Phase 2: commit (write to DB)** - -- `validate_upload_job`: scans file, records errors, transitions to `status=validated` -- `commit_upload_job`: writes to DB only after user approval via `/commit` endpoint -- Matches proposal Section 4.1: "separate validation from write" - -### Confidence Score Normalization (PSI-MI 2.7 spec) - -Parser handles all standardized confidence formats in column 15: - -- `intact-miscore:0.85` (canonical MiScore format) -- `score:0.85` or `mi-score:0.85` (variant spellings) -- `0.85` (bare float fallback) -- Returns `NULL` for `-` (missing value indicator) - -Demonstrates you actually read the spec (Section 15 credibility boost). - -See `app/parser.py:parse_confidence()` for implementation. - -### Pluggable Parser Contract (Section 4.2) - -Two parser implementations in `app/parsers.py` prove the pattern works: - -- `PSIMITabParser`: full column 15 handling, multivalue fields, namespace:value identifiers -- `CSVGeneInteractionParser`: minimal CSV (gene_a, gene_b, method, confidence, publication) - -Both implement: `sniff()`, `validate()`, `parse()`, `transform()`. - -This isn't theoretical—two concrete parsers using the same contract validates the plugin design. - -### Duplicate Detection with Visibility (Section 4.3) - -Interactions deduplicated via `UNIQUE (dataset_id, pair_key, publication_id, source_row)`. - -- Failed INSERTs (ON CONFLICT DO NOTHING) counted separately as `skipped_rows` -- Job status includes both `inserted_rows` and `skipped_rows` counters -- Enables safe re-upload: same file twice = first attempt skipped on second run -- Visible in API response under `skipped_duplicates` - -### Error Export as CSV (Section 5.2) - -`GET /uploads/jobs/{job_id}/errors/export` streams errors as CSV attachment. - -- Importable into Excel/R for validation QA -- Explicit deliverable mentioned in proposal Section 5.2: "downloadable error

(duplicate detection) -- Clear audit trail (status=parsing → validated → committed) -- Reduced risk during large ingestions (stop before DB if errors too high) - -### Parser Plugin Pattern - -`app/parsers.py` demonstrates the contract is production-ready: - -```python -class InteractionParser(Protocol): - def sniff(file_path) -> (confidence: float, hints: dict) - def validate(lines) -> Iterator[RowValidationError] - def parse(lines) -> Iterator[CanonicalInteraction] - def transform(canonical) -> dict +```bash +pytest tests/test_parser_mitab.py tests/test_parser_csv.py tests/test_integration_upload_commit.py ``` -Two implementations (PSI-MI TAB + CSV) prove this works with different schemas. - -## File Map - -- `app/main.py`: API endpoints (upload, status, commit, errors, export) -- `app/jobs.py`: `validate_upload_job` + `commit_upload_job` workers -- `app/worker.py`: ARQ WorkerSettings registration -- `app/parser.py`: Streaming PSI-MI parser with confidence normalization -- `app/parsers.py`: Parser plugin contract + two implementations (MITAB + CSV) -- `app/db.py`: Schema (upload_jobs, upload_job_errors, interactions), CRUD ops -- `app/models.py`: Domain types (CanonicalInteraction, RowValidationError) -- `app/config.py`: Environment variable loaders -- `docker-compose.yml`: postgres, redis, api, worker services -- `Dockerfile`: Python 3.11, FastAPI/ARQ entrypoint -- `sample_data/mitab_demo.tsv`: Test fixture (2 valid, 2 invalid rows) +Integration test requires PostgreSQL to be reachable on localhost:5433. diff --git

Its current Symfony/PHP implementation has grown over years of incremental feature additions and now mixes routing, parsing, persistence, and presentation logic in ways that increase maintenance cost and slow feature evolution. + +This project proposes a full rewrite of openPIP as openPIP 2.0 using modern frameworks and engineering practices: + +- Backend: Python API layer (FastAPI) with typed schemas and service boundaries +- Frontend: Next.js 14 + TypeScript for SSR-friendly public portal pages and responsive admin workflows +- Data pipeline: extensible ingestion architecture for PSI-MI TAB and CSV, with a normalized interaction domain model +- Upload/admin UX: drag-and-drop bulk upload, async job processing, progress telemetry, and row-level validation feedback +- Infrastructure: Docker-first local/dev/prod parity, object storage for uploaded files, and CI-enabled quality gates + +The outcome is a maintainable, testable, and contributor-friendly platform that preserves openPIP’s core strengths while adding robust support for diverse interaction datasets and richer metadata annotation workflows. + +--- + +## 0.1 Detailed PoC Overview (openpip2_ingestion_poc) + +Alongside proposal design, I built and iterated a working proof-of-concept in this workspace under openpip2_ingestion_poc. The PoC validates migration feasibility from legacy Symfony/PHP ingestion behavior to a modern API-plus-worker architecture while preserving operator-critical workflows. + +### Scope covered in the PoC + +- FastAPI backend with modular routers, service layer, parser layer, and DB abstraction +- Two-phase ingestion workflow: validate first, commit second +- Row-level validation error storage with remediation hints +- Error export endpoint for CSV download +- Parser extensibility through a shared parser contract with multiple implementations +- Duplicate detection and explicit counters (inserted, skipped, failed) +- Legacy compatibility routes for incremental behavior mapping +- Next.js frontend dashboard for upload, status tracking, error review, and commit action +- Progress streaming endpoint for live ingestion updates + +### Implemented ingestion workflow + +1. Upload request creates a job and stores file metadata. +2. Validation job parses rows and records structured row errors. +3. User reviews validation stage, counters, and error table. +4. Commit job writes valid canonical interactions into persistence. +5. Final status and counters remain queryable for auditability and reproducibility. + +This model is safer than single-step blind import and supports real curation practices. + +### Technical highlights delivered + +- FastAPI + asyncpg job and interaction persistence +- Worker-oriented validate/commit job boundaries +- Upload job status, error list, error export, and events endpoints +- Confidence score normalization support across common input forms +- Parser plugin structure supporting PSI-MI TAB and CSV ingestion +- Hash-based deduplication with inserted-versus-skipped visibility +- Frontend upload manager wired to backend job lifecycle + +### Migration value and current limits + +What this PoC proves: + +- Core ingestion redesign is technically viable and demonstrable end-to-end +- Legacy behavior can be wrapped and migrated incrementally without full big-bang cutover +- Upload observability and data-quality workflows are substantially improved + +Current limits: + +- Full edge-case parity with all legacy controllers is still pending +- Test coverage should expand further as parity work lands +- Production hardening (beyond dev/demo posture) remains a follow-up track + +### Code-level architecture in the PoC + +The PoC is intentionally structured around explicit boundaries, not monolithic handlers: + +- API bootstrap, lifecycle, and router composition in

Upload/admin interface with drag-drop and progress telemetry +- Acceptance criteria: multi-file upload queue supports at least 3 concurrent files; each file exposes stage states (`queued/parsing/validating/writing/completed/failed`) and downloadable row-error report. + +3. PSI-MI TAB parser (production-ready) +- Acceptance criteria: parser supports MITAB 2.5/2.6 core 15 columns, handles `|` multi-value fields, stores normalized interactors/evidence, and imports a 100k-row benchmark file with resumable progress tracking. + +4. CSV parser with explicit column mapping +- Acceptance criteria: curated CSV template + user mapping UI; validation catches missing mandatory columns and bad identifier patterns; mapped import path writes to same canonical schema as PSI-MI. + +5. Canonical interaction model with provenance tracking +- Acceptance criteria: each imported interaction links to `dataset_id`, `source_file`, `source_row`, `parser_version`, and row-level validation status; duplicate detection uses deterministic pair/evidence hash. + +6. Export module for PSI-MI TAB and CSV +- Acceptance criteria: filtered exports match canonical query results; parity tests verify row counts and mandatory column coverage against golden fixtures. + +7. Containerized development + CI pipeline +- Acceptance criteria: one-command local startup for frontend/api/worker/postgres/redis/minio; CI runs lint, type-check, unit/integration tests, and container build smoke tests. + +8. Website graph visualization for PPI exploration +- Acceptance criteria: Cytoscape.js view supports pan/zoom, layout switch, edge filtering by dataset/evidence/status, node search, and export of current subgraph selection. + +9. Documentation and contributor onboarding +- Acceptance criteria: setup docs, architecture notes, parser-extension guide, and troubleshooting page for failed imports are complete and reproducible on a clean machine. + +### 12.2 Stretch deliverables + +1.
