/// APIs within your extension code for Bevy communication.

/// # Example
///
/// ```no_run
/// use bevy_cef_core::prelude::*;
///
/// let extensions = CefExtensions::new()
///     .add("myGame", r#"
///         var myGame = {
///             sendScore: function(score) {
///                 window.cef.emit('score_update', { score: score });
///             }
