Event Management

When the app isRunning any event added via on, once, listenTo, or listenToOnce are registered with the App. These registered events are removed when the App is stopped.

const myApp = new App();

myApp.on('do:foo', function(){
  console.log('Foo!');
});

myApp.start();

myApp.on('do:bar', function(){
  console.log('Bar!');
});

// Console logs "Foo!"
myApp.trigger('do:foo');

// Console.logs "Bar!"
myApp.trigger('do:bar');

myApp.stop();

// Console logs "Foo!"
myApp.trigger('do:foo');

// Nothing in the console
myApp.trigger('do:bar');
