Itty Router is an ultra-tiny (~450B-1kB) TypeScript HTTP router library designed for serverless and edge environments like Cloudflare Workers. It provides route parsing, query params, and middleware support while remaining far smaller than Express.js.

Use cases

• build a REST API on Cloudflare Workers
• route HTTP requests in a serverless function
• tiny router for edge deployment with minimal bundle size
• handle URL params and query strings in a worker
• add middleware to a service worker fetch handler
• replace Express with a lightweight router

When to choose

• bundle size is critical, e.g. Cloudflare Workers or edge runtimes
• you want a simple, flexible router with no framework assumptions
• you're building serverless APIs in TypeScript or JavaScript

When to avoid

• you need a full-featured backend framework with built-in body parsing, sessions, or templating
• you're building a traditional Node.js monolith where Express/Fastify ecosystem matters more than size
