Angular 2 Fundamentals



animation library for angular

Overview Build Status

ng-fx is an angular implementation of the popular Animate.css using the new $animateCss service in angular. This is the core and foundation, but there is room for so much more. You can use these css animations dynamically with zero setup. So you get the best of both worlds (css vs js animations). Take a look and enjoy.

Getting started


ng-fx requires ngAnimate >=1.4. Previous versions of ng-fx <2.0 support earlier versions of ngAnimate, but dev support is lacking there. If you would love to help maintain, let me know!

using npm

  • npm i --save ng-fx
  angular.module('app', [

Using animations

ng-fx makes it so simple to use animations by tying into ngAnimate and all the hooks it provides.

First animation

After installing ng-fx, using the animations are as easy as declaring css classes on elements.

<div ng-if="show" class="fx-fade-normal"></div>

Few things happening here. First, we must tie into animations from ngAnimate, in this case we're attaching an animation to the enter and leave hooks of ng-if. Next we declare the animation type by using the fx namespace followed by the animation name (fx-fade-normal). Place this in the class of the element. That's it. ng-fx has an api to adjust the animations' speed, ease, and to stagger or not. Here's a list of all the animations ng-fx supports

Adjusting speed

ng-fx looks like innocent css animations. They are ran like css animations (performance!!!) but they are indeed dynamic like js animations as well. Here's how we can adjust the speed of an animation.

<div ng-show="error" class="fx-fade-up fx-speed-342"></div>

Using the fx-[speed | dur | duration]-{any num in ms} we can control the speed of said animation. So the following are all equivalent.

  • fx-speed-230
  • fx-dur-230
  • fx-duration-230

Adjusting the ease

  ng-repeat="card in cards"
  class="fx-fade-up fx-ease-sine">

Using fx-ease-{curve name} will apply the given curve to the animation. Here is a list of all the curves ng-fx supports. If you don't declare a direction, the ease will default to ease-in-out. You can override that...

  ng-repeat="card in cards"
  class="fx-fade-up fx-ease-in-quad">


Using `fx-ease-{direction}-{curve name}` will apply the ease direction to the curve

### Staggering
With `ngAnimate` 1.4, we now have support for staggering outside of css animations.

  ng-repeat="card in cards"
  class="fx-rotate-up-left fx-stagger-245">

Using fx-stagger-{delay in ms} on an animation in ng-repeat will stagger those elements with the given delay in between.


All help is welcome! ng-fx is an ongoing and live project. If you'd like to add more animations or support new feature, open an issue and even submit it yourself. If you're new to open source, I'll help you get your first commit in, ping me. To get started make sure you have...

  • node >=0.12
  • gulp
  • webpack

If you're good there, then...

  • fork
  • clone your fork
  • cut a new branch
  • npm install
  • npm start

This will compile and build the project. ng-fx uses ES2015, webpack, and gulp, nothing else too fancy here.

There is a demo app to try out the animations.

Most the commands you'll need are baked into npm

  • npm run build
    • builds and outputs regular and min src code
  • npm test
    • run test
  • npm start
    • run build and watch for changes to rebuild, launches the demo app and refreshes that on change.

Some helpful commands in gulp

  • gulp animation --name animation-name
    • call this command with a new animation name and it will create all the boilerplate in the src/animation/element/ that you need to get started with a new animation.
