Ember CSS Transitions

This addon provides a nice way of defining CSS Transitions for Ember Components. Which means, only css based animations for performance - and no animation library needed.

Ember CSS Transitions is heavily inspired (and CSS compatible) with Vue's CSS Transitions.

Animations are completely based on CSS classes.

How it works

Ultimately you define your animations and transitions with only css like:

/* initial state */
.example-enter,
.example-leave-to {
  opacity: 0;
}

/* final state */
.example-enter-to,
.example-leave {
  opacity: 1;
}

/* easings */
.example-enter-active,
.example-leave-active {
  transition: opacity 0.5s ease-in;
}

And using the included modifier like:

<div {{css-transition "example"}}>
  <h1>Hello world</h1>
</div>

or by manually specifying classes, perfect for libraries like Animate.css and Tailwind CSS.

{{!-- Using Tailwind CSS provided classes --}}
<div {{css-transition
  enterClass="opacity-0"
  enterActiveClass="transition-opacity duration-500 ease-in-out"
  enterToClass="opacity-100"
  leaveClass="opacity-100"
  leaveActiveClass="transition-opacity duration-500 ease-in-out"
  leaveToClass="opacity-0"}}>
  <h1>Hello world</h1>
</div>

If you are using TailwindUI then you will see transition instructions included in the code, as in this example:

<!--
  Slide-over panel, show/hide based on slide-over state.

  Entering: "transform transition ease-in-out duration-500 sm:duration-700"
    From: "translate-x-full"
    To: "translate-x-0"
  Leaving: "transform transition ease-in-out duration-500 sm:duration-700"
    From: "translate-x-0"
    To: "translate-x-full"
-->

You should map these instructions to this addon's API in the following way:

TailwindUI	Addon
Entering	enterActiveClass
From	enterClass
To	enterToClass
Leaving	leaveActiveClass
From	leaveClass
To	leaveToClass
