cloudflare-workers/_templates/cloudflare/worker-go

worker-template-go

• A template for starting a Cloudflare Worker project with Go.
• This template uses workers package to run an HTTP server.

Notice

• A free plan Cloudflare Workers only accepts ~1MB sized workers.
  • Go Wasm binaries easily exceeds this limit, so you'll need to use a paid plan of Cloudflare Workers (which accepts ~5MB sized workers).

Usage

• main.go includes simple HTTP server implementation. Feel free to edit this code and implement your own HTTP server.

Requirements

• Node.js
• wrangler
  • just run npm install -g wrangler
• Go

$ cd my-app

$ go mod tidy
$ make dev # start running dev server
$ curl http://localhost:8787/hello
Hello!

• To change worker name, please edit name property in wrangler.toml.
