Ember Component Action Bubbling

This addon allows you to call an action from a nested component and have it bubble up the hierarchy all the way to the root component, then on to the current controller, its route, eventually reaching the application route, simliar to how Controller and Route's send() works in Ember:

• Bubbling will continue while actions along the chain keep returning true, until reaching the application route.

• If a component along the chain does not implement the action, bubbling will skip to its parent.

The addon is very simple and all it does is reintroduce behaviour that was already present thanks to this lovely little bug.

Installation

• ember install ember-component-action-bubbling

Code Example

// parent
export default Ember.Component.extend({
  actions: {
    say(something) {
      console.log('repeating', something); // stops here
    }
  }
});

// child
export default Ember.Component.extend({
  actions: {
    say(something) {
      console.log('saying', something);
      return true; // continues
    }
  }
});

// grand child
export default Ember.Component.extend({
  click() {
    this.bubble('say', 'Hello!');
  }
});
