in the last line you see the warning

Thanks

Hello, I have seen this warning. But I am not familiar with this. I don't know what it can do?

[sxmxta]

demo-link: https://timhutton.github.io/opengl-canvas-wasm Do you open this link in Energy to see if it's correct? Is it the effect you want?

[JSchmidt63]

The warning is occurring when printing dialog is created. Maybe it is a bug in cef, but i don't know that?

• demo-link: https://html5test.co/ site is running but a logger warning

• demo-link: https://timhutton.github.io/opengl-canvas-wasm site is running but a logger warning

thanks

Perhaps this warning has no impact, I am not familiar with it. But I tested several WebAssembly WASM websites and examples, and they all worked fine

Golang WebAssembly (Wasm): https://github.com/maxence-charriere/go-app Use go-app build site :https://go-app.dev/

The website above https://go-app.dev/ Open directly in Energy

Here is an example of Wasm generated by running go app

No obvious abnormalities were found

package main

import (
    "github.com/maxence-charriere/go-app/v10/pkg/app"
    "log"
    "net/http"
)

// hello is a component that displays a simple "Hello World!". A component is a
// customizable, independent, and reusable UI element. It is created by
// embedding app.Compo into a struct.
type hello struct {
    app.Compo
}

// The Render method is where the component appearance is defined. Here, a
// "Hello World!" is displayed as a heading.
func (h *hello) Render() app.UI {
    return app.H1().Text("Hello World!")
}

// The main function is the entry point where the app is configured and started.
// It is executed in 2 different environments: A client (the web browser) and a
// server.
func main() {
    // The first thing to do is to associate the hello component with a path.
    //
    // This is done by calling the Route() function,  which tells go-app what
    // component to display for a given path, on both client and server-side.
    app.Route("/", func() app.Composer { return &hello{} })

    // Once the routes set up, the next thing to do is to either launch the app
    // or the server that serves the app.
    //
    // When executed on the client-side, the RunWhenOnBrowser() function
    // launches the app,  starting a loop that listens for app events and
    // executes client instructions. Since it is a blocking call, the code below
    // it will never be executed.
    //
    // When executed on the server-side, RunWhenOnBrowser() does nothing, which
    // lets room for server implementation without the need for precompiling
    // instructions.
    app.RunWhenOnBrowser()

    // Finally, launching the server that serves the app is done by using the Go
    // standard HTTP package.
    //
    // The Handler is an HTTP handler that serves the client and all its
    // required resources to make it work into a web browser. Here it is
    // configured to handle requests with a path that starts with "/".
    http.Handle("/", &app.Handler{
        Name:        "Hello",
        Description: "An Hello World! example",
    })

    if err := http.ListenAndServe(":8000", nil); err != nil {
        log.Fatal(err)
    }
}
