As there are differences between the latest Go and Go 1.11 beta, I recommend to use the latest Go here.

Get the latest Go

  1. Checkout the latest Go (https://go.googlesource.com/go)
  2. Compile the compiler by running ./make.bash

Compile your game

GOOS=js GOARCH=wasm /path/to/latest/gocode/bin/go build -o yourgame.wasm github.com/yourname/yourgame

Copy wasm_exec.js to execute the Wasm binary

cp /path/to/latest/gocode/bin/go/misc/wasm_exec.js .

Create an HTML

<!DOCTYPE html>
<script src="wasm_exec.js"></script>
<script>
// Polyfill
if (!WebAssembly.instantiateStreaming) {
  WebAssembly.instantiateStreaming = async (resp, importObject) => {
    const source = await (await resp).arrayBuffer();
    return await WebAssembly.instantiate(source, importObject);
  };
}

const go = new Go();
WebAssembly.instantiateStreaming(fetch("yourgame.wasm"), go.importObject).then(result => {
  go.run(result.instance);
});
</script>

TBD
