+To instruct wrangler to automatically rebuild nitro when it detects file changes, you need to add the following rule to your `wrangler.toml` file:
+
+```[wrangler.toml]
++ [env.development.build]
++ command = "NITRO_PRESET=cloudflare npm run build" // Replace npm with your packagemanager (npm, pnpm, yarn, bun)
++ cwd = "./"
++ watch_dir = ["./routes", "./nitro.config.ts"]
+```

+When files change in nitro, wrangler will rebuild and serve the new files
