Transition Page Recycler using Animated Recycler View

Mobile Animation Using AngularJs

AngularJS provides an excellent way to create single page applications. this allows for our website to feel a lot of and a lot of like a native mobile application since we've got a single page app. To create it feel even more native, we are able to add transitions and animations using ngAnimate module.

Mobile Animation Using AngularJs

This module allows us to make stunning looking applications. Nowadays we’ll be looking at how to animate ng-view.

Mobile Animation Using AngularJs

What We’ll Be Building

Let’s say we've one page application wherever we would like to animate the page change. Clicking on a link will slide one view out and another into view.

Difference : AngularJS vs. Backbone.js vs. Ember.js

We’ll use:

  • ngRoute for our page routing
  • ngAnimate to create our page animations
  • CSS Animations will be applied to the pages
  • Each of our pages will have different animations when leaving or entering the view

Extreme Animations: The animations we’ll be using here are a little over the top. Animations that are subtle can be useful for your production sites, we’re just going crazy for demonstration purposes.

How will It Work?

Let’s take a look at however ngAnimate works. ngAnimate can add and take away CSS classes to totally different Angular directives based on if they're entering or leaving the view. as an example, when we load a website, no matter is populated in ng-view gets a .ng-enter class.

All we've to do is apply a CSS animation to that .ng-enter class which are applied upon entry.

ngAnimate Works On: ngRepeat, ngInclude, ngIf, ngSwitch, ngShow, ngHide, ngView, and ngClass
Definitely go through the ngAnimate documentation to see additional of what ngAnimate will do. currently let’s see it in action.

Starting Our Application

Here are the files we’ll need.
  1.     - index.html
  2.     - style.css
  3.     - app.js
  4.     - page-home.html
  5.     - page-about.html
  6.     - page-contact.html
Let’s start up an index.html file. We’ll load up AngularJS, ngRoute, and ngAnimate. Oh and don’t forget Bootstrap for stylings.


<!-- index.html -->
<!DOCTYPE html>

    <!-- CSS -->
    <!-- load bootstrap (bootswatch version) -->
    <link rel="stylesheet" href="//">
    <link rel="stylesheet" href="style.css">
    <!-- JS -->
    <!-- load angular, ngRoute, ngAnimate -->
    <script src=""></script>
    <script src=""></script>
    <script src=""></script>
    <script src="app.js"></script>


<!-- apply our angular app -->
<body ng-app="animateApp">

    <!-- inject our views using ng-view -->
    <!-- each angular controller applies a different class here -->
    <div class="page {{ pageClass }}" ng-view></div>
Here is our very simple HTML file. Load up our resources necessary, apply our Angular app, and add ng-view for our injected views.
Let’s take a look at the other files we’ll need.

  1.     - index.html
  2.     - style.css
  3.     - app.js
  4.     - page-home.html
  5.     - page-about.html
  6.     - page-contact.html

Our Angular Application app.js

Now we will create our Angular application with routing so that we can change pages without a page refresh.


var animateApp = angular.module('animateApp', ['ngRoute', 'ngAnimate']);

// ROUTING ===============================================
// set our routing for this application
// each route will pull in a different controller
animateApp.config(function($routeProvider) {


        // home page
        .when('/', {
            templateUrl: 'page-home.html',
            controller: 'mainController'

        // about page
        .when('/about', {
            templateUrl: 'page-about.html',
            controller: 'aboutController'

        // contact page
        .when('/contact', {
            templateUrl: 'page-contact.html',
            controller: 'contactController'


// CONTROLLERS ============================================
// home page controller
animateApp.controller('mainController', function($scope) {
    $scope.pageClass = 'page-home';

// about page controller
animateApp.controller('aboutController', function($scope) {
    $scope.pageClass = 'page-about';

// contact page controller
animateApp.controller('contactController', function($scope) {
    $scope.pageClass = 'page-contact';

We have currently created our application, created our routing, and created our controllers.

Each controller can have its own pageClass variable. this is applied to our ng-view within the index.html file so that we've a different class for every page. With a different class for every page, we'll be ready to apply totally different animations to every specific page.

Views page-home.html, page-about.html, page-contact.html

These will be clean and straightforward. We just need some text for each and the links to the other pages.


<h1>Angular Animations Shenanigans</h1>

<a href="#about" class="btn btn-success btn-lg">About</a>
<a href="#contact" class="btn btn-danger btn-lg">Contact</a>


<h1>Animating Pages Is Fun</h1>

<a href="#" class="btn btn-primary btn-lg">Home</a>
<a href="#contact" class="btn btn-danger btn-lg">Contact</a>


<h1>Tons of Animations</h1> 

<a href="#" class="btn btn-primary btn-lg">Home</a>
<a href="#about" class="btn btn-success btn-lg">About</a>

We currently have our pages and that they are injected into our main index.html file with the ability of Angular routing.

Now all the boring stuff is completed. Our app should work and be able to change pages nicely. currently let’s get to the part we actually wanted, the animations!

Animating Our App style.css

All of the animations we'll create will be with CSS. this is nice because all we had to try to to was add ngAnimate and currently, without any changes to our Angular code, we can apply CSS animations.

Two classes that ngAnimate adds to our ng-view are .ng-enter and .ng-leave. you'll be able to guess what each of those are used for.

BASE styles

Here we’ll add some base designs so that our app doesn’t look too boring.
/* make our pages be full width and full height */
/* positioned absolutely so that the pages can overlap each other as they enter and leave */
.page        {

.page h1    { font-size:60px; }
.page a     { margin-top:50px; }

/* PAGES (specific colors for each page)
============================================================================= */
.page-home      { background:#00D0BC; color:#00907c; }
.page-about     { background:#E59400; color:#a55400; }
.page-contact   { background:#ffa6bb; color:#9e0000; }

With that, we've base styles for all 3 pages. As we click through our app, we will see those applied with the colours and spacing.


Let’s define our animations then we’ll look at how we will apply them to every of the pages as they enter and leave.

Vendor Prefixes: we are going to be using the default CSS attributes without the vendor prefixes. the complete code can have all the vendor prefixes.

Let’s make six different animations. every page can have their very own ng-enter and ng-leave animation.


============================================================================= */

/* leaving animations ----------------------------------------- */
/* rotate and fall */
@keyframes rotateFall {
    0%      { transform: rotateZ(0deg); }
    20%     { transform: rotateZ(10deg); animation-timing-function: ease-out; }
    40%     { transform: rotateZ(17deg); }
    60%     { transform: rotateZ(16deg); }
    100%    { transform: translateY(100%) rotateZ(17deg); }

/* slide in from the bottom */
@keyframes slideOutLeft {
    to      { transform: translateX(-100%); }

/* rotate out newspaper */
@keyframes rotateOutNewspaper {
    to      { transform: translateZ(-3000px) rotateZ(360deg); opacity: 0; }

/* entering animations --------------------------------------- */
/* scale up */
@keyframes scaleUp {
    from    { opacity: 0.3; -webkit-transform: scale(0.8); }

/* slide in from the right */
@keyframes slideInRight {
    from    { transform:translateX(100%); }
    to      { transform: translateX(0); }

/* slide in from the bottom */
@keyframes slideInUp {
    from    { transform:translateY(100%); }
    to      { transform: translateY(0); }

With these animations all made, we will now apply them to our pages.


To apply our animations to our pages, we will just apply these animations to .ng-enter or .ng-leave.
/* style.css */

    .ng-enter           { animation: scaleUp 0.5s both ease-in; z-index: 8888; }
    .ng-leave           { animation: slideOutLeft 0.5s both ease-in; z-index: 9999; }

Now our application can animate just like that. Pages can slide out to the left once leaving and scale up once entering. we also added z-index so that the page leaving would be placed on top of the one entering.

Let’s look at creating page specific animations.


We created separate Angular controllers for every of the pages. inside of these controllers we added a pageClass and applied that to our <div ng-view>. We’ll use these classes to call out a page specifically.
Instead of the .ng-enter and .ng-leave code on top of, let’s create them page specific.

    .ng-enter       { z-index: 8888; }
    .ng-leave       { z-index: 9999; }

    /* page specific animations ------------------------ */

    /* home -------------------------- */         { animation: scaleUp 0.5s both ease-in; }         { transform-origin: 0% 0%; animation: rotateFall 1s both ease-in; }

    /* about ------------------------ */        { animation:slideInRight 0.5s both ease-in; }        { animation:slideOutLeft 0.5s both ease-in; }

    /* contact ---------------------- */      { transform-origin: 50% 50%; animation: rotateOutNewspaper .5s both ease-in; }      { animation:slideInUp 0.5s both ease-in; }

Now each page will have its own unique enter and leave animation!


It’s fairly easy to add animations to your Angular application. All you have to do is load up ngAnimate and create your CSS animations. Hopefully this has helped you see a couple cool things you can animate when using ng-view.

We’ll be creating other articles on how to animate with ngRepeat, ngSwitch, and all of its brothers.
