Experimental — APIs may change between releases

Run Go on Cloudflare Workers, and beyond

Your Go code compiles to WebAssembly, and workers-go bridges the JavaScript runtime APIs to idiomatic Go types.

$go get github.com/syumai/workers-go

One handler, every runtime

Write a plain http.Handler. workers-go serves it on Cloudflare Workers, in the browser, on Neon Functions, and on Deno.

Cloudflare Workers

Serve http.Handler on Workers and Pages Functions, with KV, R2, D1, Queues, Cron, Durable Objects, and more.

Browser

Serve HTTP from a Go Wasm binary running inside a browser tab with the browser template.

Neon Functions

Run the same http.Handler on Neon's serverless functions platform.

Deno / Deno Deploy

Serve http.Handler via Deno.serve on Deno and Deno Deploy.

package main

import (
	"fmt"
	"net/http"

	"github.com/syumai/workers-go"
)

func main() {
	http.HandleFunc("/hello", func(w http.ResponseWriter, req *http.Request) {
		fmt.Fprintf(w, "Hello, %s!", req.URL.Query().Get("name"))
	})
	workers.Serve(nil) // if nil is given, http.DefaultServeMux is used
}

The Workers platform, from Go

Bindings and triggers for the runtime APIs — stable where it matters, experimental where the platform is still moving.

http.Handler, unchanged
KV, R2, D1, and the Cache API
Queues, Cron, and FetchEvent
Durable Objects, WebSocket, RPC, and Workflows
TCP Sockets and Service Bindings
Workers AI, Vectorize, and Images
