Go2JS

Compile Go to JS in the browser (using GopherJS)

Based on GopherJS Playground

The motive for this project was to enable client-side compiling of Golang to JavaScript to run in the browser for LiveCodes.

Usage

UMD:

<!-- <script src="https://cdn.jsdelivr.net/npm/@live-codes/go2js/build/go2js.js"></script> -->
<script src="go2js.js"></script>
<script>
  const code = `
package main
import ("syscall/js"
"fmt")
func main() {fmt.Println("Hello, from Go")
js.Global().Call("alert", "Hello, JavaScript")
println("Hello, JS console")}
`;
  window.go2js
    .format(code)
    .then((formatted) => {
      console.log(formatted);
      // return window.go2js.compile(formatted, 'https://cdn.jsdelivr.net/npm/@live-codes/go2js/build/');
      return window.go2js.compile(formatted);
    })
    .then(eval)
    .catch(console.warn);
</script>

ESM:

import { compile, format } from 'https://cdn.jsdelivr.net/npm/@live-codes/go2js';

const code = `
package main
import ("syscall/js"
"fmt")
func main() {fmt.Println("Hello, from Go")
js.Global().Call("alert", "Hello, JavaScript")
println("Hello, JS console")}
`;

format(code)
  .then((formatted) => {
    console.log(formatted);
    // return compile(formatted, 'https://cdn.jsdelivr.net/npm/@live-codes/go2js/build/');
    return compile(formatted);
  })
  .then(eval)
  .catch(console.warn);
