I'm starting a new project and saw a very interesting library for GO which is somewhat similar to fasthtml called go-app.

I'm struggling to execute simple JS commands like console.log or alert. Or am I missing something?

type Button struct {
    app.Compo
}

func (b *Button) OnClick(ctx app.Context, e app.Event) {
    // NONE of these codes works when clicking the button.

    //e.JSValue().Call("alert", "e jsvalue call Button clicked!")
    //ctx.JSSrc().Call("alert", "ctx jssrc call Button clicked!")

    //app.Window().Get("alert").Call("window get call Hello world")
    //app.Window().Call("alert", "window call Button clicked!")
    app.Window().Get("console").Call("log", "window get call log")
}

func (b *Button) Render() app.UI {
    return app.Button().
        ID("button").
        Text("Click me!").
        OnClick(b.OnClick)
}

Try this if it will work:

type Button struct {
    app.Compo
}

func (b *Button) OnClick(ctx app.Context, e app.Event) {
    // Access the window object and call the alert function
    app.Window().Call("alert", "Button clicked alert!")

    // Or directly access console.log from the window
    app.Window().Get("console").Call("log", "clicked!")
}

func (b *Button) Render() app.UI {
    return app.Button().
        ID("button").
        Text("Click Button!").
        OnClick(b.OnClick)
}
