"route.js" + + # Next.js Pages Router + find pages/api -name "*.ts" -o -name "*.js" + + # Express/Node + grep -r "router.get\|router.post\|router.put\|router.delete" --include="*.ts" + + # FastAPI +

The Swamp of POX (Plain Old XML/JSON) + +**Description**: Single endpoint, single HTTP method, RPC-style + +**Found in Codebase**: ❌ NONE (good - no Level 0 APIs) + +**Bad Example** (what NOT to do): +```typescript +// ❌ Level 0: Everything through one endpoint +POST /api/endpoint +{ + "action": "getUser", + "userId": "123" +} + +POST /api/endpoint +{ + "action": "createUser", + "data": { "name": "John" } +} +``` + +--- + +### Level 1: Resources + +**Description**: Multiple endpoints, each representing a resource + +**Found in Codebase**: ✅ PARTIAL (80% compliance) + +**Good Examples**: +```typescript +// ✅ Level 1: Resource-based URLs +GET /api/users // app/api/users/route.ts +GET /api/users/[id] // app/api/users/[id]/route.ts +GET /api/orders // app/api/orders/route.ts +GET /api/products // app/api/products/route.ts +``` + +**Anti-Pattern Examples** (need fixing): +```typescript +// ❌ RPC-style (verb in URL) +POST /api/createUser // Should be: POST /api/users +POST /api/deleteOrder // Should be: DELETE /api/orders/{id} +GET /api/getUserProfile // Should be: GET /api/users/{id} + +// ❌ Mixed conventions +GET /api/user-list // Uses kebab-case +GET /api/orderList // Uses camelCase (inconsistent!) +GET /api/product_catalog // Uses snake_case (inconsistent!) +``` + +**Consistency Score: 6/10** (multiple naming conventions) + +**Recommendations**: +1. **Refactor RPC-style URLs** (3 endpoints need fixing) + - `POST /api/createUser` → `POST /api/users` + - `POST /api/deleteOrder` → `DELETE /api/orders/{id}` + - `GET /api/getUserProfile` → `GET /api/users/{id}` + +2. **Standardize naming convention** - Use kebab-case for all multi-word resources + - `GET /api/orderList` → `GET /api/orders` + - `GET /api/product_catalog` → `GET /api/products` + +--- + +### Level 2: HTTP Verbs + +**Description**: Proper use of HTTP methods (GET, POST, PUT, PATCH, DELETE) + +**Found in Codebase**: ✅ GOOD (85% correct usage) + +**Good Examples**: +```typescript +// ✅ Correct HTTP verb usage +// app/api/orders/route.ts +export async function GET(request: Request) { + // Fetch orders (idempotent, safe) + const orders = await db.order.findMany() + return NextResponse.json({ orders }) +} + +export async function POST(request: Request) { + // Create order (non-idempotent) + const data = await request.json() + const order = await db.order.create({ data }) + return NextResponse.json({ order }, { status: 201 }) +} + +// app/api/orders/[id]/route.ts +export async function GET(request: Request, { params }: { params: { id: string } }) { + // Fetch single order + const order = await db.order.findUnique({ where: { id: params.id } }) + if (!order) return NextResponse.json({ error: 'Not found' }, { status: 404 }) + return NextResponse.json({ order }) +} + +export async function PATCH(request: Request, { params }: { params: { id: string } }) { + // Partial update (idempotent) + const data = await request.json() + const order = await db.order.update({ where: { id: params.id }, data }) + return NextResponse.json({ order }) +} + +export async function DELETE(request: Request, { params }: { params: { id: string } }) { + // Delete (idempotent) + await db.order.delete({ where: { id: params.id } }) + return NextResponse.json({ success: true }, { status: 204 }) +} +``` + +**Anti-Patterns Found**: +```typescript +// ❌ Using POST for updates (should use PUT/PATCH) +// app/api/users/[id]/update/route.ts +export async function POST(request: Request, { params }) { + // ❌ BAD: POST is not idempotent, should be PATCH + const updated = await db.user.update({ where: { id: params.id }, data }) + return NextResponse.json({ user: updated }) +} + +// ❌ Using GET with side effects (should use POST) +// app/api/orders/[id]/cancel/route.ts +export async function GET(request: Request, { params }) { + // ❌ BAD: GET should be safe (no side effects) + await db.order.update({ where: { id: params.id }, data: { status: 'cancelled' } }) + return NextResponse.json({ success: true }) +} + +// ❌ Using DELETE with request body (non-standard) +export async function DELETE(request: Request) { + const { ids } = await request.json() // ❌ DELETE shouldn't have body + await db.order.deleteMany({ where: { id: { in: ids } } }) + return NextResponse.json({ success: true }) +} +``` + +**HTTP Verb Quality: 7/10** +- ✅ Most endpoints use correct verbs +- ❌ 3 endpoints use POST instead of PATCH/PUT +- ❌ 1 endpoint uses GET with side effects (security issue!) +- ❌ 1 endpoint uses DELETE with body (non-standard) + +**Why This Matters**: +- **GET with side effects** breaks caching and causes accidental actions (security vulnerability) +- **POST for updates** breaks idempotency (retry = duplicate) +- **DELETE with body** is not supported by all HTTP clients + +**Recommendations**: +1. **FIX CRITICAL**: Change `/api/orders/[id]/cancel` from GET to POST (security issue) +2. **Fix HTTP verb misuse**: 3 endpoints need PATCH instead of POST +3. **Standardize bulk delete**: Use POST `/api/orders/bulk-delete` instead of DELETE with body + +--- + +### Level 3: HATEOAS (Hypermedia Controls) + +**Description**: Responses include hypermedia links for discoverability + +**Found in Codebase**: ❌ NOT IMPLEMENTED + +**Current Response** (missing HATEOAS): +```typescript +// app/api/orders/[id]/route.ts +export async function GET(request: Request, { params }) { + const order = await db.order.findUnique({ where: { id: params.id } }) + return NextResponse.json({ order }) +} + +// ❌ Response lacks navigation links +{ + "order": { + "id": "ord_123", + "status": "pending", + "total": 99.99 + } +} +``` + +**Level 3 Implementation** (with HATEOAS): +```typescript +export async function GET(request: Request, { params }) { + const order = await db.order.findUnique({ where: { id: params.id } }) + + return NextResponse.json({ + order, + _links: { + self: { href: `/api/orders/${order.id}` }, + cancel: order.status === 'pending' + ? { href: `/api/orders/${order.id}/cancel`, method: 'POST' } + : undefined, + user: { href: `/api/users/${order.userId}` }, + items: { href: `/api/orders/${order.id}/items` } + } + }) +} + +// ✅ Response with HATEOAS +{ + "order": { + "id": "ord_123", + "status": "pending", + "total": 99.99 + }, + "_links": { + "self": { "href": "/api/orders/ord_123" }, + "cancel": { "href":

implemented) + +**Why HATEOAS Matters**: +- Clients discover available actions dynamically +- API is self-documenting +- Server can change URLs without breaking clients +- Enables workflow-driven UIs + +**Recommendation**: MEDIUM PRIORITY +- Implement HATEOAS for primary resources (orders, users, products) +- Start with `_links` wrapper for common actions + +--- + +## REST Maturity Summary + +| Level | Description | Status | Score | +|-------|-------------|--------|-------| +| 0 | Single endpoint POX | ❌ None (good!) | N/A | +| 1 | Resources | ✅ Partial | 6/10 | +| 2 | HTTP Verbs | ✅ Good | 7/10 | +| 3 | HATEOAS | ❌ Not implemented | 0/10 | + +**Overall REST Maturity**: 2.0/3.0 (GOOD, with room for improvement) + +**Critical Issues**: +1. 🔴 **GET with side effects**

DO: Use correct HTTP verbs (GET = safe, POST = create, PATCH = update) +- ✅ DO: Return correct status codes (404 for not found, 409 for conflicts) +- ✅ DO: Use Zod for request validation +- ✅ DO: Follow standard error format (code, message, details) +- ❌ DON'T: Use GET for operations with side effects (security issue!) +- ❌ DON'T: Mix naming conventions (pick one: kebab-case) +- ❌ DON'T: Return different error formats per endpoint +- ❌ DON'T: Use POST for updates (use PATCH/PUT) + +**Best Examples in Codebase**: +- Good REST: `app/api/orders/route.ts` (proper verbs, resource modeling) +- Good validation: `app/api/checkout/route.ts` (uses Zod) + +**Anti-Patterns to Avoid**: +- GET with side effects: `/api/orders/[id]/cancel` (FIX THIS!) +- RPC-style URLs: `/api/createUser`, `/api/deleteOrder` +- Inconsistent errors: `app/api/users/route.ts` vs `app/api/orders/route.ts` +- Manual validation: `app/api/products/route.ts` (use Zod instead) + +**Standard Error Format**:
