aeo-sdk-typescript

TypeScript SDK for the AEO Protocol v0.1 — parse, build, validate, and fetch AEO declaration documents. Zero-runtime-cost types via zod.

Install

npm install aeo-protocol

Quickstart

import { fetchWellKnown, parseDocument, claimIds, findClaim } from "aeo-protocol";

// Fetch and parse from a live well-known URL
const doc = await fetchWellKnown("https://mizcausevic-dev.github.io");
console.log(doc.entity.name);                          // "Miz Causevic"
console.log(claimIds(doc));                            // ['current-role', ...]
console.log(findClaim(doc, "years-experience")?.value); // 30

// Parse from a string
const docFromString = parseDocument('{"aeo_version":"0.1",...}');

// Validate safely
import { safeParseDocument } from "aeo-protocol";
const result = safeParseDocument(maybeMalformed);
if (!result.success) console.error(result.error);

What it does

• Parse — parseDocument(raw) and safeParseDocument(value) for strict and recoverable parsing
• Build — full zod schemas (documentSchema, entitySchema, etc.) and inferred TypeScript types (AeoDocument, Entity, Claim, ...)
• Serialize — serializeDocument(doc, indent) returns canonical JSON
• Fetch — fetchWellKnown(origin, { timeoutMs }) discovers and parses against /.well-known/aeo.json with Accept: application/aeo+json, application/json
• Query — claimIds(doc) and findClaim(doc, id) for convenience

Conformance

Supports the AEO Protocol at conformance Level 1 (Declare). Signature verification (L2) and audit-endpoint posting (L3) deferred to v0.2.

TypeScript types

Every model has both a zod schema and an inferred type. Import either:

import { documentSchema, type AeoDocument } from "aeo-protocol";

const validated: AeoDocument = documentSchema.parse(someUnknown);

Dependencies

• zod ^3.23 — runtime validation + type inference
• Native fetch (Node 18+, all modern browsers and runtimes)

Development

npm install
npm run typecheck
npm test
npm run build
