Relay — Express REST API Starter (JWT Auth + CRUD)

Relay is a production-shaped REST API starter built with Express. JWT authentication, a validated resource CRUD, security middleware and consistent error handling in a clean layered structure — plus a built-in interactive API explorer served at /.

A real backend foundation, not a hello-world: layered routes → services → data, with auth, validation and security wired in.

Highlights

• JWT auth (register/login/me), bcrypt-hashed passwords, authenticate middleware.
• Notes CRUD owned by the user: list (search, pinned filter, pagination), create, read, update, delete.
• zod validation, consistent JSON error shape, central error handler.
• Security: helmet, cors, body limit, auth rate limiting.
• Interactive API explorer (quick demo-login, send requests, view responses).
• Swappable in-memory data layer, ESM, Node 18+, no build step.
