API Generator
Create endpoints from requirements. User never writes routes.
Process
-
Identify resources
- "Manage expenses" → /api/expenses
- "User profile" → /api/users/me
-
Generate CRUD
- GET (list, single)
- POST (create)
- PUT/PATCH (update)
- DELETE (remove)
-
Add validation
- Input schemas
- Error handling
- Auth middleware
-
Generate OpenAPI
- Auto-document all endpoints
- For future integrations
Template-Specific
Next.js API Routes
// app/api/expenses/route.ts
export async function GET() {
const expenses = await db.expenses.findMany();
return Response.json(expenses);
}
export async function POST(req: Request) {
const data = await req.json();
const expense = await db.expenses.create({ data });
return Response.json(expense);
}
FastAPI
@router.get("/expenses")
async def list_expenses(db: Session = Depends(get_db)):
return db.query(Expense).all()
@router.post("/expenses")
async def create_expense(data: ExpenseCreate, db: Session = Depends(get_db)):
expense = Expense(**data.dict())
db.add(expense)
db.commit()
return expense
Hono
app.get('/expenses', async (c) => {
const expenses = await db.select().from(expensesTable);
return c.json(expenses);
});
app.post('/expenses', async (c) => {
const data = await c.req.json();
const [expense] = await db.insert(expensesTable).values(data).returning();
return c.json(expense);
});
