Requirement Specification: Virtual Account Generation + +## 1.1 Functional Requirements (FR) + +**FR-01: Identity Mapping** + +- The system must use the User’s unique internal ID as the `reference` when calling Globus. This ensures we can always trace a NUBAN back to a specific user, even if the database is corrupted. + +**FR-02: Idempotency (Duplicate Prevention)** + +- The system must check if a user _already_ has a Virtual Account before attempting to create one. +- If the Bank API returns an error saying "Reference already exists," the system must gracefully query the Bank to fetch the existing account details instead of throwing an error. + +**FR-03: Data Consistency** + +- The Account Name at the Bank **MUST** match the format: `AppName - UserFirstName UserLastName` (e.g., "SwapLink - John Doe"). This gives users confidence when they see the name during a transfer. + +**FR-04: Tier-Based Creation** + +- The system shall generate a Tier 1 (Low Limit) account using just Phone/Name if allowed by Globus Sandbox. +- If Globus enforces BVN, the system must queue the creation request until the User submits their BVN. + +**FR-05: Notification** + +- Upon successful generation of the NUBAN, the system must trigger a notification (Push/Email) to the user: _"Your SwapLink account number is ready!"_ + +--- + +## 1.2 Non-Functional Requirements (NFR) & Implementation Strategies + +This is the "Fintech Grade" engineering section. + +### NFR-01: High Availability (Non-Blocking) + +- **Requirement:** The Registration endpoint (`POST /register`) must respond within **500ms**, regardless of Bank API status. +- **Strategy:** **Event-Driven Architecture**. + - User registers -> Save to DB -> Return `200 OK`. + - Emit event `USER_REGISTERED`. + - A background worker picks up this event and calls Globus. + +### NFR-02: Fault Tolerance (Retries) + +- **Requirement:** If Globus returns a `5xx` error (Server Error) or `408` (Timeout), the system must retry the request automatically. +- **Strategy:** **Exponential Backoff**. + - Retry 1: Wait 5s. + - Retry 2: Wait 20s. + - Retry 3: Wait 1 min. + - If all fail, verify manually or alert Admin. + +### NFR-03: Rate Limiting (Throttling) + +- **Requirement:** The system must not exceed Globus's API rate limits (e.g., 50 requests/sec), otherwise Globus will block your IP. +- **Strategy:** **Job Queue (BullMQ)**. + - Add account creation jobs to a queue. + - Configure the queue worker to process only X jobs per second. + +### NFR-04: Security (Token Management) + +- **Requirement:** Client Secrets and Access Tokens must never appear in logs. +- **Strategy:** **Token Caching**. + - Fetch the Globus Auth Token once. + - Cache it in Redis/Memory for 55 minutes (if it expires in 60). + - Only request a new token when the cache expires. + +--- + +# 2. The Asynchronous Architecture + +Instead of doing everything in the Controller, we split it. + +### Phase 1: User Registration (Synchronous) + +- **Input:** Email, Password, Phone. +- **Action:** Create User row, Create Internal Wallet (NUBAN = null). +- **Response:** `201 Created` (User enters the app immediately). + +### Phase 2: The Worker (Background) + +- **Trigger:** Queue Job `create-virtual-account`. +- **Action:** Call Globus API. +- **Result:** Update `VirtualAccount` table -> Send Push Notification. + +--- + +# 3.

It is designed to help you get up to speed quickly, even if you are revisiting the project after a long time. + +## 1. Environment Setup + +### Prerequisites + +Ensure you have the following installed: + +- **Node.js** (v18 or higher) - [Download](https://nodejs.org/) +- **pnpm** (Package Manager) - `npm install -g pnpm` +- **Docker & Docker Compose** - For running database and redis easily. +- **PostgreSQL Client** (Optional) - For manual DB inspection. + +### Configuration (.env) + +The application relies on environment variables. + +1. Copy the example file: + ```bash + cp .env.example .env + ``` +2. **Critical Variables**: + - `DATABASE_URL`: Connection string for PostgreSQL. + - `REDIS_URL`: Connection string for Redis. + - `JWT_SECRET`: Secret key for signing tokens. + - `ADMIN_EMAIL` / `ADMIN_PASSWORD`: Default Super Admin credentials for seeding. + +--- + +## 2. Running the Application + +You have two main ways to run the app: **Hybrid (Recommended)** or **Local**. + +### Option A: Hybrid (Docker for Infra + Local Node) + +This is the best experience for development.

Good for verifying production-like behavior. + +```bash +pnpm dev:full +``` + +--- + +## 3. Database Management + +We use **Prisma ORM**. Here are the common commands: + +- **Update Schema**: After changing `prisma/schema.prisma`: + + ```bash + pnpm db:migrate + ``` + + _This generates the SQL migration file and applies it._ + +- **Reset Database**: **WARNING: Deletes all data!** + + ```bash + pnpm db:reset + ``` + +- **View Data (GUI)**: + ```bash + pnpm db:studio + ``` + _Opens a web interface at `http://localhost:5555` to browse data._ + +--- + +## 4. Testing + +We use **Jest** for testing. Tests are located in `src/**/*.test.ts` or `src/test/`. + +### Test Environment + +Tests use a separate database to avoid messing up your development data. + +1. Create `.env.test` (copy `.env.example` and change DB name to `swaplink_test`). +2.

If they fail, try running them individually. + +--- + +## 5. Common Issues & Fixes + +### "Connection Refused" (DB/Redis) + +- Check if Docker containers are running: `docker ps` +- Ensure ports 5432 and 6379 are not occupied by other services. + +### "Prisma Client not initialized" + +- Run `pnpm db:generate` to regenerate the client after `npm install`. + +### "TypeScript Errors during Build" + +- Run `pnpm build:check` to see type errors without emitting files. +- Ensure you are importing types from `src/shared/database` (the central export) rather than generated paths directly if possible. diff --git a/docs/guides/DOCKER.md b/docs/guides/DOCKER.md new file mode 100644 index 0000000..0698cb8 --- /dev/null +++ b/docs/guides/DOCKER.md @@ -0,0 +1,122 @@ +# Docker Guide for SwapLink + +This guide details how to use Docker effectively for development, testing, and deployment of the SwapLink Server. + +## 🐳 Docker Profiles + +We use **Docker Profiles** to manage different running modes.

Multiple Devices Support +Users may log in from multiple devices (e.g., iPhone and Android). Storing a single `pushToken` string on the `User` model will overwrite the previous device's token. + +**Recommended Schema:** +Create a `Device` model. + +```prisma +model Device { + id String @id @default(uuid()) + token String @unique + platform String // 'ios' | 'android' + userId String + user User @relation(fields: [userId], references: [id]) + createdAt DateTime @default(now()) +} +```` + +### 2. Handling Invalid Tokens (Receipts) + +Expo tokens can become invalid (e.g., user uninstalls app). You **must** check for error receipts and delete invalid tokens to avoid sending messages to dead ends. + +```typescript +// In NotificationService +// ... inside the chunk loop +try { + const tickets = await expo.sendPushNotificationsAsync(chunk); + + // Process tickets to identify errors + tickets.forEach(ticket => { + if (ticket.status === 'error') { + if (ticket.details && ticket.details.error === 'DeviceNotRegistered') { + // TODO: Delete this specific token from the Device table + console.log('Token is invalid, deleting...'); + } + } + }); +} catch (error) { + console.error('Error sending chunk:', error); +} +``` + +### 3. Security + +Ensure the `PUT /users/push-token` endpoint is protected by your authentication middleware. + +## 4. Usage Example + +When a transfer is received, you can call the service: + +```typescript +// Inside TransferService or TransferWorker + +import { NotificationService } from
