Express.js Router Stub Builder

Generate an Express router with CRUD routes and middleware

Creates an Express router file with GET/POST/PUT/DELETE handlers, an async error wrapper, an input-validation middleware stub, and an authentication guard — ready to drop into a Node.js project.

Does the generated router actually run?

It is a working skeleton with real route wiring and an async error wrapper. The handler bodies return placeholder JSON, so you replace those lines with your own database calls and business logic.

Scaffold an Express router in seconds

Building a REST resource in Express means writing the same five routes — list, read, create, update, delete — plus the boilerplate that wraps async handlers, validates input, and checks authentication. This builder generates a complete, syntactically correct router for any resource so you can replace the placeholder bodies with your real logic instead of typing the skeleton by hand.

How it works

You provide a singular resource name such as user. The tool lowercases it, pluralises it (a simple s/es/ies rule), and produces handler names like listUsers and createUser. It then assembles a Router() with five routes mapped to REST conventions:

GET    /        -> list all
GET    /:id     -> read one
POST   /        -> create
PUT    /:id     -> update
DELETE /:id     -> delete

Each handler is wrapped in an asyncHandler helper that catches rejected promises and forwards them to next(), so thrown errors reach your error-handling middleware instead of crashing the request. Optional middleware — an auth guard that inspects the Authorization header and a validation stub for the create/update bodies — is inserted only on the routes that need it. You can target CommonJS (require / module.exports) or ES modules (import / export default).

Tips and notes

  • Mount the router with a base path: app.use('/users', usersRouter). The routes inside the file stay relative.
  • Keep the asyncHandler wrapper even after you add your own logic — it is the single cleanest way to avoid unhandled-rejection bugs.
  • The validation stub is intentionally minimal. Swap it for a real schema validator such as Zod, Joi, or express-validator.
  • Replace the placeholder responses (res.json(...)) with your repository or ORM calls. The status codes (200, 201, 204) already follow REST conventions.
