Plugins

• keyboard-shortcut: this plugin adds keyboard shortcut handling
• view-transitions: this plugin adds view transitions support

Plugins allow you to extend Umbra with custom UI components or behavior.

1. Constructor - Plugin is instantiated with the Umbra instance as host
2. render() - Called during initialization
3. onThemeChange() - Called whenever the theme changes (including sync from other tabs)
4. onDestroy() - Called when umbra.destroy() is invoked

The host parameter is your Umbra instance. You can call:

class MyPlugin implements Plugin {
 public static readonly pluginId = 'u-<something>'; // Required
 private host: Host;
 constructor(host: Host) {
 this.host = host;
 // Access: host.theme, host.toggleTheme(), host.getCurrentTheme()
 }
 render(): void | HTMLElement {
 throw new Error("Method not implemented.");
 }
 
 onThemeChange(theme: string): void {
 console.log('Theme changed to:', theme);
 }
}
