ExpressJS API Example

This example starts an ExpressJS server written in TypeScript.

Features

• Express 5
• TypeScript
• Security headers via helmet
• CORS enabled

How to use

• Install dependencies pnpm install
• Copy .env.example to .env (optional, defaults to port 3333)
• Start the development server pnpm dev
• Build for production pnpm build

Notes

The server returns a healthcheck status: "ok" payload in JSON at the root. The server code is located in src/index.ts.

A versioned API route is available in src/api.ts with an example endpoint at /api/v1/hello.

Express 5 handles async route handlers natively — no wrapper needed.

Railway

Set NODE_ENV=production in your Railway service variables. Railway does not set this automatically.
