Easy transitions in react and react-router

Usage

For a simple fade-out fade-in effect on route change with react-router :

import EasyTransition from 'react-easy-transition'

<EasyTransition
    path={location.pathname}
    initialStyle={{opacity: 0}}
    transition="opacity 0.3s ease-in"
    finalStyle={{opacity: 1}}
>
    {this.props.children}
</EasyTransition>

Multiple transitions on different properties:

<EasyTransition
    path={location.pathname}
    initialStyle={{opacity: 0, color: 'red'}}
    transition="opacity 0.3s ease-in, color 0.5s ease-in"
    finalStyle={{opacity: 1, color: 'green'}}
>
    {this.props.children}
</EasyTransition>

Optionally set a leaveStyle if it is different than the initialStyle:

<EasyTransition
    path={location.pathname}
    initialStyle={{opacity: 0, color: 'red'}}
    transition="opacity 0.3s ease-in, color 0.5s ease-in"
    finalStyle={{opacity: 1, color: 'green'}}
    leaveStyle={{opacity: 0, color: 'gray'}}
>
    {this.props.children}
</EasyTransition>

You can set a custom component or classname if needed

<EasyTransition
    path={location.pathname}
    initialStyle={{opacity: 0, color: 'red'}}
    transition="opacity 0.3s ease-in, color 0.5s ease-in"
    finalStyle={{opacity: 1, color: 'green'}}
    component="MyCustomReactComponent"
    className="myCustomCSSClass"
>
    {this.props.children}
</EasyTransition>

NOTE: If your <Link> component (or any children of this) contains styling/classes that use transition, make sure not to use transition: all as this will prevent react-easy-transition from fading out.

Features

• Small : only 70 lines of code
• Lightweight : based on ReactTransitionGroup low level API
• Easy: works out of the box with React Router 2.0, no need to define CSS classes, use Javascript objects to define transition styles.
• Performance : still using native browser CSS transition under the hood
• Flexible : support for multiple transitions

This module solves the following issues:

• The fade-in effect when component mounts is rather straightforward to do with pure CSS transitions. However, the fade-out effect is impossible to do using only CSS because the component disappears immediately when unmounted.
• The new component appears before the end of the fade-out transition of the previous component, so both are shown at the same time, one on top of the other.
• Transition on initial render when rendering on the server

Example

• Integration with react-router, redux, and server-side rendering in ./demo/
