Liquid-fire-events NPM

Liquid-fire-events

Provides a service liquid-fire-events that you can use to subscribe to the following events from Liquid Fire: transitionBegan and transitionAnimated.

Example usage:

export default Ember.Component.extend({
  liquidFireEvents: Ember.inject.service(),
  didInsertElement() {
    this.get('liquidFireEvents')
      .on('transitionBegan', () => {
        this.set('animating', true);
      }).on('transitionAnimated'), (newView) => {
        this.set('animating', false);
      });
  }
});

Note: these are global events, fired every time a Liquid Fire transition occurs anywhere within the rendered DOM.

Additionally, this addon provides a component delayed-render which wraps a block of markup and only renders it after a transition has finished. This is useful eg. to avoid rendering while animating, a common cause of jank especially in mobile browsers.

Example usage:

{{my-navigation-bar}}
{{! my-complex-component will not be rendered until the animation is complete}}
{{#delayed-render}}
  {{my-complex-component}}
{{/delayed-render}}
