angular-animate

What is angular-animate?

The angular-animate package is an AngularJS module that provides support for JavaScript, CSS3 transition, and CSS3 keyframe animation hooks within your AngularJS applications. It allows you to create smooth, complex animations for various elements and states in your application.

What are angular-animate's main functionalities?

CSS-based animations

This feature allows you to define CSS classes for entering and leaving animations. The .ng-enter and .ng-leave classes are used to define the starting state of the animation, while the .ng-enter-active and .ng-leave-active classes define the end state.

/* CSS code */
.fade.ng-enter {
  transition: 0.5s linear all;
  opacity: 0;
}
.fade.ng-enter-active {
  opacity: 1;
}
.fade.ng-leave {
  transition: 0.5s linear all;
  opacity: 1;
}
.fade.ng-leave-active {
  opacity: 0;
}

JavaScript-based animations

This feature allows you to define animations using JavaScript. You can create custom animations for entering and leaving elements by manipulating their CSS properties and using jQuery's animate function.

// JavaScript code
angular.module('myApp', ['ngAnimate'])
  .animation('.slide', function() {
    return {
      enter: function(element, done) {
        element.css({
          position: 'relative',
          left: '-10px',
          opacity: 0
        });
        element.animate({
          left: '0px',
          opacity: 1
        }, 1000, done);
      },
      leave: function(element, done) {
        element.css({
          position: 'relative',
          left: '0px',
          opacity: 1
        });
        element.animate({
          left: '-10px',
          opacity: 0
        }, 1000, done);
      }
    };
  });

ngAnimate directive

The ngAnimate directive can be used to apply animations to elements within an AngularJS application. In this example, the .fade class is applied to each item in the ng-repeat directive, and the corresponding CSS animations are triggered when items are added or removed.

<div ng-app="myApp" ng-controller="myCtrl">
  <div ng-repeat="item in items" class="fade">
    {{item}}
  </div>
</div>

<script>
angular.module('myApp', ['ngAnimate'])
  .controller('myCtrl', function($scope) {
    $scope.items = ['Item 1', 'Item 2', 'Item 3'];
  });
</script>

Other packages similar to angular-animate

ng2-animate

ng2-animate is an Angular (2+) module that provides a set of reusable animations for Angular applications. It offers a variety of pre-built animations that can be easily applied to elements, making it simpler to add animations without writing custom CSS or JavaScript. Compared to angular-animate, ng2-animate is designed for newer versions of Angular and provides a more modern approach to animations.

react-transition-group

react-transition-group is a popular library for managing animations in React applications. It provides components like Transition, CSSTransition, and TransitionGroup to handle the entering and exiting of elements with animations. While it serves a similar purpose to angular-animate, it is specifically designed for React and offers a different API and set of features tailored to React's component-based architecture.

animejs

animejs is a lightweight JavaScript animation library that works with any JavaScript framework, including AngularJS. It provides a powerful and flexible API for creating complex animations with minimal code. Unlike angular-animate, which is tightly integrated with AngularJS, animejs is a general-purpose animation library that can be used across different frameworks and projects.
