Installation

Usage

implement your http.Handler and give it to workers.Serve().

func main() {
	var handler http.HandlerFunc = func (w http.ResponseWriter, req *http.Request) { ... }
	workers.Serve(handler)
}

or just call http.Handle and http.HandleFunc, then invoke workers.Serve() with nil.

func main() {
	http.HandleFunc("/hello", func (w http.ResponseWriter, req *http.Request) { ... })
	workers.Serve(nil) // if nil is given, http.DefaultServeMux is used.
}

For concrete examples, see examples directory. Currently, all examples use tinygo instead of Go due to binary size issues.

A template repository is also available.

FAQ

How do I deploy a worker implemented in this package?

To deploy a Worker, the following steps are required.

• Create a worker project using wrangler.
• Build a Wasm binary.
• Upload a Wasm binary with a JavaScript code to load and instantiate Wasm (for entry point).

The worker-template-tinygo repository contains all the required files, so I recommend using this template.
