Notes on running Go in the browser with WebAssembly (via) Neat, concise tutorial by Eli Bendersky on compiling Go applications that can then be loaded into a browser using WebAssembly and integrated with JavaScript. Go functions can be exported to JavaScript like this:
js.Global().Set("calcHarmonic", jsCalcHarmonic)
And Go code can even access the DOM using a pattern like this:
doc := js.Global().Get("document")
inputElement := doc.Call("getElementById", "timeInput")
input := inputElement.Get("value")
Bundling the WASM Go runtime involves a 2.5MB file load, but there’s also a TinyGo alternative which reduces that size to a fourth.
