Class InstallerEventEmitter

Type-safe wrapper around Node.js EventEmitter for installer events.

Provides compile-time enforcement that event names and handler signatures match the InstallerEventMap. The engine creates one emitter instance and exposes InstallerEngine.On / InstallerEngine.Off for frontend subscription.

Example

const emitter = new InstallerEventEmitter();
emitter.On('log', (e) => {
  if (e.Level === 'info') console.log(e.Message);
});
emitter.Emit('log', { Type: 'log', Level: 'info', Message: 'Hello' });
