Css Animations in react.js are handled through the ReactCSSTransitionGroup Api. It provides a way to perform css when components enter or leave the DOM. ReactCSSTransitionGroup requires three elements to work.

The ReactCSSTransitionGroup element wraps the content that you want to appear with css animation.

transitionName=”example”

…transition options…

This element must be initiated with a transitionName, which tells react which css animation to render out. when specifying the css animation the class name and transitionName must match. The transition options specify when the animation should occur, and for how long. The most common time for a component to be rendered is , as it is entering the DOM and as its leaving. You can specify this by using special key words reserved for ReactCSSTransitionGroup elements. For example:

transitionName=”example”

Next you need to specify an element that you want to render. ReactCSSTransitionGroup accepts single or multiple elements. The tag wraps around the specific element that you want to animate as in

You may pass in javascript arrays, strings, jsx, or even other components in the tag. However all elements even single elements should have a key prop.

The last element that you must specify to have a working animation is the css styling that specify the animation properties. The css code should match the transitionName and transition properties in the following format. The transitionName gets translated to a class name that you select in css, followed by the transition property.

opacity: 0.01;

opacity: 1;

transition: opacity 2s ease-in;

In this example the element will fade in from the background starting at an opacity of 0.01 to an opacity of 1 in two seconds.

React.js allows you to set animations to elements in your react application with ReactCSSTransitionGroup api. In true react style, ReactCSSTransitionGroup is declarative specifying only what you want to happen without specifying step by step how it will happen. This allows other developers to get an idea of the exact state of the program at any given time.

ReactCSSTransitionGroup works well for simple css animations but other options exist for more complex animations ie: animations that involve motion. For these check out the following resources

usage:

import { bounce } from ‘react-animations’;

import { StyleSheet, css } from ‘aphrodite’;

bounce: {

animationName: bounce,

animationDuration: ‘1s’

React Motion: a javascript library that handles the physics of component animation and provides an easy to use api for accessing those animations. With react motion developers can create more complex ui rendering. find more information here: https://github.com/chenglou/react-motion. Nash Vail also wrote a great tutorial on motion that can be found here: https://medium.com/@nashvail/a-gentle-introduction-to-react-motion-dc50dd9f2459

usage:

React Flip Move: react flip move is a library that allows you to animate flips for your react components. It works best when rendering a list of items, and can animate when mounting and un-mounting components. for more information see: https://github.com/joshwcomeau/react-flip-move

usage:

import FlipMove from ‘react-flip-move’;
