Runtimes > Cloudflare Workers - itty-router

Itty-router was originally designed for Cloudflare Workers, and remains its optimization target to this day.

import { AutoRouter } from 'itty-router'

const router = AutoRouter()

router.get('/', () => 'Success!')

export default router // see note below

Currently, there's a bug in Wrangler that affects local development using wrangler dev when trying to export the router directly. We're working with the Cloudflare folks to get this fixed ASAP.

In the meantime, destructure your root router like this to avoid the issue:

export default { ...router } // this looks pointless, but trust us
