Component + Mixin to prevent rendering content before route is fully rendered.

Information

NPM

Install in ember-cli application

In your application's directory:

ember install ember-wait-for-render

Usage

  • Add the wait-for-render Mixin to your route.
// pods/index/route.js
import WaitForRenderMixin from 'ember-wait-for-render/mixins/wait-for-render';
 
export default Route.extend(WaitForRenderMixin, {
  // ...
});
  • Use the component in your template.
{{!-- pods/index/template.hbs --}}
 
{{my-component}}
 
{{!-- this block will be rendered after my-component is fully drawed --}}
{{#wait-for-render}}
  {{my-delayed-component}}
{{/wait-for-render}}

for attribute

The for attribute can be used to render global components (in application.hbs) that doesn't has to be drawed before the user reaches certain page.

A typical example is an application menu that is hidden until the user has logged.

  • Add the wait-for-render Mixin to your route.

  • Use the component in your application template.

{{!-- pods/application/template.hbs --}}
 
{{my-login-stuff}}
 
{{!-- this block will be rendered after user reaches 'dashboard' route --}}
{{#wait-for-render for="dashboard"}}
  {{my-menu}}
{{/wait-for-render}}

Promises with for

The for attribute also accepts A+ promises (an object with a then method is required).

A little example:

{{!-- controller.js --}}
Ember.Controller.extend({
  // Set any promise into the view context
  promise: new Ember.RSVP.Promise().resolve()
});
{{!-- template.hbs --}}
 
{{#wait-for-render for=promise}}
  {{my-component}}
{{/wait-for-render}}

Integration with liquid-fire

  • Reopen the wait-for-render component and change the layout.
import Ember from 'ember';
import WaitForRenderComponent from 'ember-wait-for-render/components/wait-for-render';
 
WaitForRenderComponent.reopen({
 
  layout: Ember.computed(function() {
    const layoutName = this.get('layoutName');
    const layout = this.templateForName(layoutName, 'layout');
 
    Ember.assert(`You specified the layoutName ${layoutName} for ${this}, but it did not exist.`, !layoutName || !!layout);
 
    return layout || this.get('defaultLayout');
  }),
 
  layoutName: 'wait-for-render'
 
});
  • Write your custom template.
{{!-- wait-for-render/template.hbs --}}
{{#liquid-if _rendered class="wait-for-render"}}
  {{yield}}
{{/liquid-if}}
  • Define the transition.
// app/transitions.js
this.transition(
  this.hasClass('wait-for-render'),
  this.toValue(true),
  this.use('crossFade', { duration: 400 }),
  this.reverse('crossFade', { duration: 400 })
);
