Dealing with bloated JavaScript frameworks is painful, let it Go and handle it by yourself with a zero-dependency tool designed for WebAssembly.
String- This is an interface that requiresString() stringto be implemented.IsValue(interface{})- Check if a value can be used asjs.Value.
Subscription.Channel()- Returns a sender channel.Subscription.Handler(Handler)- However data should be handled here; the Handler argument is a function where it takes data andjs.Value.New()- Returns a*Subscriptioninstance and guaranteed to exist, else it panics.
In HTML the element must include a field id.
The example is split into two parts, HTML shows the required HTML code, and Go shows the required WebAssembly Go code.
<html lang="en">
<head>
<title>Proto</title>
<meta charset="utf-8"/>
<script src="wasm_exec.js"></script>
<script>
const go = new Go();
WebAssembly.instantiateStreaming(fetch("/main.wasm"), go.importObject).then((result) => {
go.run(result.instance);
});
</script>
</head>
<body>
<span id="example">Loading...</span>
</body>
</html>package main
import (
"github.com/Dviih/proto"
"syscall/js"
"time"
)
func main() {
example := proto.New("example")
go func() {
for {
example.Channel() <- "Example"
time.Sleep(time.Nanosecond) // Go is quite fast.
}
}()
go example.Handler(func(i interface{}, value js.Value) {
value.Set("innerHTML", i)
})
}
