itty-router

An ultra-tiny API microrouter, for use when size matters (e.g. Cloudflare Workers).

---

Features

• Tiny, with zero dependencies. Routers from ~450 bytes to a ~970 bytes batteries-included version (~240-500x smaller than Express.js).
• TypeScript. Powerfully (and flexibly) typed for any environment.
• Route-parsing & query parsing.
• Middleware. Use ours or write your own.
• 100% Test Coverage. Bulletproof for production peace-of-mind.
• Designed specifically for serverless (but works anywhere).
• No assumptions. Return anything; pass in anything.
• Future-proof. HTTP methods not-yet-invented already work with it.

Example

import { AutoRouter } from 'itty-router' // ~1kB

const router = AutoRouter()

router
  .get('/hello/:name', ({ name }) => `Hello, ${name}!`)
  .get('/json', () => [1,2,3])
  .get('/promises', () => Promise.resolve('foo'))

export default router

// that's it ^-^
