ember-cli-liquid-fire-events

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

DEMO

Compatibility

• Ember.js v2.18 or above
• Ember CLI v2.13 or above

Installation

ember install ember-cli-liquid-fire-events

Usage

Example usage:

export default Ember.Component.extend({
  liquidFireEvents: Ember.inject.service(),
  didInsertElement() {
	this.get('liquidFireEvents')
	  .on('transitionStart', () => {
		this.set('animating', true);
	}).on('transitionEnd'), (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 liquid-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}}
{{#liquid-delayed-render}}
  {{my-complex-component}}
{{/liquid-delayed-render}}
