This example is running in WebGL2 and should work in most browsers. You can check the WebGPU examples here.

//! Demonstrates the creation and registration of a custom plugin group.
//! [`PluginGroup`]s are a way to group sets of plugins that should be registered together.

use bevy::{app::PluginGroupBuilder, prelude::*};

fn main() {
            // Two PluginGroups that are included with bevy are DefaultPlugins and MinimalPlugins
            // Adding a plugin group adds all plugins in the group by default
        // You can also modify a PluginGroup (such as disabling plugins) like this:
        // .add_plugins(
        //     HelloWorldPlugins
        //         .build()
        //         .disable::<PrintWorldPlugin>()
        //         .add_before::<PrintHelloPlugin, _>(
        //             bevy::diagnostic::LogDiagnosticsPlugin::default(),
        //         ),
        // )
