如何加载新版本react addon

在低版本的react中，npm调用react addon时，用

var React = require("react/addons");

但是新版本这样写则报了警告

Warning: require('react/addons') is deprecated. Access using require('react-addons-{addon}') instead

解决需要两个步骤

一：npm下载新的addon包，在官网上已经讲的十分清楚

Add-onsEdit on GitHub

The React add-ons are a collection of useful utility modules for building React apps. These should be considered experimental and tend to change more often than the core.

• TransitionGroup and CSSTransitionGroup, for dealing with animations and transitions that are usually not simple to implement, such as before a component's removal.
• LinkedStateMixin, to simplify the coordination between user's form input data and the component's state.
• cloneWithProps, to make shallow copies of React components and change their props.
• createFragment, to create a set of externally-keyed children.
• update, a helper function that makes dealing with immutable data in JavaScript easier.
• PureRenderMixin, a performance booster under certain situations.
• shallowCompare, a helper function that performs a shallow comparison for props and state in a component to decide if a component should update.

The add-ons below are in the development (unminified) version of React only:

• TestUtils, simple helpers for writing test cases (unminified build only).
• Perf, for measuring performance and giving you hint where to optimize.

To get the add-ons, install them individually from npm (e.g., npm install react-addons-pure-render-mixin). We don't support using the addons if you're not using npm.

如我想引入动画插件 则写成

npm install react-addons-css-transition-group

二：引入新的文件

 var React = require("react");var CSSTransitionGroup = require('react-addons-css-transition-group')

react的引入是必要的

这样就不会再报警告了 而且react高版本会彻底废弃react/addons写法 请尽早更改为单独调用形式
