* Update example snippet in old 'React.addons' doc page This makes the example more consistent. * Add back the pointers in docs that were mistakenly removed In https://github.com/facebook/react/pull/9359 we accidentally removed pointers in some doc pages. Putting them back now. * Link to npm package instead of github page This seems like a more stable place to link to in the 'context' document. Based on @bvaughn's feedback in https://github.com/facebook/react/pull/9359

>Note:
|
|
> `React.addons` is deprecated as of React v15.5. The add-ons have now all either been deprecated or moved to separate modules.
|
|
|
|
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.
|
|
|
|
- [`createFragment`](create-fragment.html), to create a set of externally-keyed children.
|
|
|
|
The add-ons below are in the development (unminified) version of React only:
|
|
|
|
- [`Perf`](perf.html), a performance profiling tool for finding optimization opportunities.
|
|
- [`ReactTestUtils`](test-utils.html), simple helpers for writing test cases.
|
|
|
|
### Legacy Add-ons
|
|
|
|
The add-ons below are considered legacy and their use is discouraged.
|
|
|
|
- [`PureRenderMixin`](pure-render-mixin.html). Use [`React.PureComponent`](/react/docs/react-api.html#react.purecomponent) instead.
|
|
- [`shallowCompare`](shallow-compare.html), a helper function that performs a shallow comparison for props and state in a component to decide if a component should update.
|
|
- [`update`](update.html). Use [`kolodny/immutability-helper`](https://github.com/kolodny/immutability-helper) instead.
|
|
|
|
### Deprecated Add-ons
|
|
|
|
- [`LinkedStateMixin`](two-way-binding-helpers.html) has been deprecated.
|
|
- [`TransitionGroup` and `CSSTransitionGroup`](animation.html) have been deprecated.
|
|
|
|
## Using React with Add-ons
|
|
|
|
You can install the add-ons individually from npm (e.g. `npm install react-addons-create-fragment`) and import them:
|
|
|
|
```javascript
|
|
import createFragment from 'react-addons-create-fragment'; // ES6
|
|
var createFragment = require('react-addons-create-fragment'); // ES5 with npm
|
|
```
|
|
|
|
When using a CDN, you can use `react-with-addons.js` instead of `react.js`:
|
|
|
|
```html
|
|
<script src="https://unpkg.com/react@15/dist/react-with-addons.js"></script>
|
|
```
|
|
|
|
The add-ons will be available via the `React.addons` global (e.g. `React.addons.TestUtils`).
