9e11fb626e Docs: Give headers ids for easy linking
This gives markdown headers an id so that we can link directly to
sections of our docs. This is better than the alternative of adding them

c12929700a Redirect /docs to the right page
I've hit this a few times where I want to get to docs so I take whatever
my urlbar gives me and strip out the actual page so I can get to the
root, however that's a 404.

This introduces a super easy way to redirect, which could be handy in
the future as docs get rewritten.

I would much rather do this with a real htaccess file or even just
handle 404s gracefully, but that's not currently an option with GitHub
pages (since we generate our own and don't use a custom domain).

title: "Use React and JSX in Ruby on Rails"
layout: post
author: Paul O'Shannessy
---
Today we're releasing a gem to make it easier to use React and JSX in Ruby on Rails applications: [react-rails](https://github.com/facebook/react-rails).
This gem has 2 primary purposes:
1. To package `react.js` in a way that's easy to use and easy to update.
2. To allow you to write JSX without an external build step to transform that into JS.
## Packaging react.js
To make `react.js` available for use client-side, simply add `react` to your manifest, and declare the variant you'd like to use in your environment. When you use `:production`, the minified and optimized `react.min.js` will be used instead of the development version. For example:
```ruby
# config/environments/development.rb
MyApp::Application.configure do
config.react.variant = :development
# use :production in production.rb
end
```
```js
// app/assets/javascript/application.js
//= require react
```
## Writing JSX
When you name your file with `myfile.js.jsx`, `react-rails` will automatically try to transform that file. For the time being, we still require that you include the docblock at the beginning of the file. For example, this file will get transformed on request.
```js
/** @jsx React.DOM */
React.renderComponent(<MyComponent/>, document.body)
```
## Asset Pipeline
`react-rails` takes advantage of the [asset pipeline](http://guides.rubyonrails.org/asset_pipeline.html) that was introduced in Rails 3.1. A very important part of that pipeline is the `assets:precompile` Rake task. `react-rails` will ensure that your JSX files will be transformed into regular JS before all of your assets are minified and packaged.
## Installation
Installation follows the same process you're familiar with. You can install it globally with `gem install react-rails`, though we suggest you add the dependency to your `Gemfile` directly.

This is the first Community Round-up where none of the items are from Facebook/Instagram employees. It's great to see the adoption of React growing.
## React Game Tutorial
[Caleb Cassel](https://twitter.com/CalebCassel) wrote a [step-by-step tutorial](https://rawgithub.com/calebcassel/react-demo/master/part1.html) about making a small game. It covers JSX, State and Events, Embedded Components and Integration with Backbone.

## Reactify
[Andrey Popp](http://andreypopp.com/) created a [Browserify](http://browserify.org/) helper to compile JSX files.
> Browserify v2 transform for `text/jsx`. Basic usage is:
>
> ```
% browserify -t reactify main.jsx

## React Integration with Este
[Daniel Steigerwald](http://daniel.steigerwald.cz/) is now using React within [Este](https://github.com/steida/este), which is a development stack for web apps in CoffeeScript that are statically typed using the Closure Library.
```coffeescript
este.demos.react.todoApp = este.react.create (`/** @lends {React.ReactComponent.prototype} */`)
render: ->
@div [
este.demos.react.todoList 'items': @state['items']
if @state['items'].length
@p "#{@state['items'].length} items."
@form 'onSubmit': @onFormSubmit, [
@input
'onChange': @onChange
'value': @state['text']
'autoFocus': true
'ref': 'textInput'
@button "Add ##{@state['items'].length + 1}"
]
]
```

[Zaim Bakar](http://zaim.github.io/) shared his boilerplate to get started with Stylus CSS processor.
> This is my boilerplate React project using Grunt as the build tool, and Stylus as my CSS preprocessor.
>
> - Very minimal HTML boilerplate

## WebFUI
[Conrad Barski](http://lisperati.com/), author of the popular book [Land of Lisp](http://landoflisp.com/), wants to use React for his ClojureScript library called [WebFUI](https://github.com/drcode/webfui).
> I'm the author of "[Land of Lisp](http://landoflisp.com/)" and I love your framework. I built a somewhat similar framework a year ago [WebFUI](https://github.com/drcode/webfui) aimed at ClojureScript. My framework also uses global event delegates, a global "render" function, DOM reconciliation, etc just like react.js. (Of course these ideas all have been floating around the ether for ages, always great to see more people building on them.)
>
> Your implementation is more robust, and so I think the next point release of webfui will simply delegate all the "hard work" to react.js and will only focus on the areas where it adds value (enabling purely functional UI programming in clojurescript, and some other stuff related to streamlining event handling)

title: "Use React and JSX in Python Applications"
layout: post
author: Kunal Mehta
---
Today we're happy to announce the initial release of [PyReact](https://github.com/facebook/react-python), which makes it easier to use React and JSX in your Python applications. It's designed to provide an API to transform your JSX files into JavaScript, as well as provide access to the latest React source files.
## Usage
Transform your JSX files via the provided `jsx` module:
```python
from react import jsx
# For multiple paths, use the JSXTransformer class.
transformer = jsx.JSXTransformer()
for jsx_path, js_path in my_paths:
transformer.transform(jsx_path, js_path)
# For a single file, you can use a shortcut method.
jsx.transform('path/to/input/file.jsx', 'path/to/output/file.js')
```
For full paths to React files, use the `source` module:
```python
from react import source
# path_for raises IOError if the file doesn't exist.
react_js = source.path_for('react.min.js')
```
## Django
PyReact includes a JSX compiler for [django-pipeline](https://github.com/cyberdelia/django-pipeline). Add it to your project's pipeline settings like this:
```python
PIPELINE_COMPILERS = (
'react.utils.pipeline.JSXCompiler',
)
```
## Installation
PyReact is hosted on PyPI, and can be installed with `pip`:
$ pip install PyReact
Alternatively, add it into your `requirements` file:
PyReact==0.1.1
**Dependencies**: PyReact uses [PyExecJS](https://github.com/doloopwhile/PyExecJS) to execute the bundled React code, which requires that a JS runtime environment is installed on your machine. We don't explicitly set a dependency on a runtime environment; Mac OS X comes bundled with one. If you're on a different platform, we recommend [PyV8](https://code.google.com/p/pyv8/).
For the initial release, we've only tested on Python 2.7. Look out for support for Python 3 in the future, and if you see anything that can be improved, we welcome your [contributions](https://github.com/facebook/react-python/blob/master/CONTRIBUTING.md)!

[Ben Newman](https://twitter.com/benjamn) made a [13-lines wrapper](https://github.com/benjamn/meteor-react/blob/master/lib/mixin.js) to use React and Meteor together. [Meteor](http://www.meteor.com/) handles the real-time data synchronization between client and server. React provides the declarative way to write the interface and only updates the parts of the UI that changed.
> This repository defines a Meteor package that automatically integrates the React rendering framework on both the client and the server, to complement or replace the default Handlebars templating system.
>
> The React core is officially agnostic about how you fetch and update your data, so it is far from obvious which approach is the best. This package provides one answer to that question (use Meteor!), and I hope you will find it a compelling combination.

>var MyComponent = React.createClass({

> return { foo: Session.get('foo') };
> },
>
> render: function() {
> return <div>{this.state.foo}</div>;
> }
>});
>```
>
> Dependencies will be registered for any data accesses performed by getMeteorState so that the component can be automatically re-rendered whenever the data changes.

## React Page
[Jordan Walke](https://github.com/jordwalke) implemented a complete React project creator called [react-page](https://github.com/facebook/react-page/). It supports both server-side and client-side rendering, source transform and packaging JSX files using CommonJS modules, and instant reload.

>
> * `react-page` computes page markup on the server, sends it to the client so the user can see it quickly.
> * The corresponding JavaScript is then packaged and sent.
> * The browser runs that JavaScript, so that all of the event handlers, interactions and update code will run seamlessly on top of the server generated markup.

A lot has happened in the month since our last update. Here are some of the more interesting things we've found. But first, we have a couple updates before we share links.
First, we are organizing a [React Hackathon](http://reactjshack-a-thon.splashthat.com/) in Facebook's Seattle office on Saturday September 28. If you want to hack on React, meet some of the team or win some prizes, feel free to join us!
We've also reached a point where there are too many questions for us to handle directly. We're encouraging people to ask questions on [StackOverflow](http://stackoverflow.com/questions/tagged/reactjs) using the tag [[reactjs]](http://stackoverflow.com/questions/tagged/reactjs). Many members of the team and community have subscribed to the tag, so feel free to ask questions there. We think these will be more discoverable than Google Groups archives or IRC logs.
## Javascript Jabber
[Pete Hunt](http://www.petehunt.net/) and [Jordan Walke](https://github.com/jordwalke) were interviewed on [Javascript Jabber](http://javascriptjabber.com/073-jsj-react-with-pete-hunt-and-jordan-walke/) for an hour. They go over many aspects of React such as 60 FPS, Data binding, Performance, Diffing Algorithm, DOM Manipulation, Node.js support, server-side rendering, JSX, requestAnimationFrame and the community. This is a gold mine of information about React.
> **PETE:** So React was designed all around that. Conceptually, how you build a React app is that every time your data changes, it's like hitting the refresh button in a server-rendered app. What we do is we conceptually throw out all of the markup and event handlers that you've registered and we reset the whole page and then we redraw the entire page. If you're writing a server-rendered app, handling updates is really easy because you hit the refresh button and you're pretty much guaranteed to get what you expect.
>
> **MERRICK:** That's true. You don't get into these odd states.
>
> **PETE:** Exactly, exactly. In order to implement that, we communicate it as a fake DOM. What we'll do is rather than throw out the actual browser html and event handlers, we have an internal representation of what the page looks like and then we generate a brand new representation of what we want the page to look like. Then we perform this really, really fast diffing algorithm between those two page representations, DOM representations. Then React will compute the minimum set of DOM mutations it needs to make to bring the page up to date.
>
> Then to finally get to answer your question, that set of DOM mutations then goes into a queue and we can plug in arbitrary flushing strategies for that. For example, when we originally launched React in open source, every setState would immediately trigger a flush to the DOM. That wasn't part of the contract of setState, but that was just our strategy and it worked pretty well. Then this totally awesome open source contributor Ben Alpert at Khan Academy built a new batching strategy which would basically queue up every single DOM update and state change that happened within an event tick and would execute them in bulk at the end of the event tick.

## JSXTransformer Trick
While this is not going to work for all the attributes since they are camelCased in React, this is a pretty cool trick.

## Remarkable React
[Stoyan Stefanov](http://www.phpied.com/) gave a talk at [BrazilJS](http://braziljs.com.br/) about React and wrote an article with the content of the presentation. He goes through the difficulties of writting _active apps_ using the DOM API and shows how React handles it.
> So how does exactly React deal with it internally? Two crazy ideas - virtual DOM and synthetic events.
>
> You define you components in React. It builds a virtual DOM in JavaScript land which is way more efficient. Then it updates the DOM. (And "virtual DOM" is a very big name for what is simply a JavaScript object with nested key-value pairs)
>
> Data changes. React computes a diff (in JavaScript land, which is, of course, much more efficient) and updates the single table cell that needs to change. React replicates the state of the virtual DOM into the actual DOM only when and where it's necessary. And does it all at once, in most cases in a single tick of the `requestAnimationFrame()`.
>
> What about event handlers? They are synthetic. React uses event delegation to listen way at the top of the React tree. So removing a node in the virtual DOM has no effect on the event handling.
>
> The events are automatically cross-browser (they are React events). They are also much closer to W3C than any browser. That means that for example `e.target` works, no need to look for the event object or checking whether it's `e.target` or `e.srcElement` (IE). Bubbling and capturing phases also work cross browser. React also takes the liberty of making some small fixes, e.g. the event `<input onChange>` fires when you type, not when blur away from the input. And of course, event delegation is used as the most efficient way to handle events. You know that "thou shall use event delegation" is also commonly given advice for making web apps snappy.
>
> The good thing about the virtual DOM is that it's all in JavaScript land. You build all your UI in JavaScript. Which means it can be rendered on the server side, so you initial view is fast (and any SEO concerns are addressed). Also, if there are especially heavy operations they can be threaded into WebWorkers, which otherwise have no DOM access.

## Markdown in React
[Ben Alpert](http://benalpert.com/) converted [marked](https://github.com/chjj/marked), a Markdown Javascript implementation, in React: [marked-react](https://github.com/spicyj/marked-react). Even without using JSX, the HTML generation is now a lot cleaner. It is also safer as forgetting a call to `escape` will not introduce an XSS vulnerability.

[Ross Allen](https://twitter.com/ssorallen) working at [Mesosphere](http://mesosphere.io/) combined [Turbolinks](https://github.com/rails/turbolinks/), a library used by Ruby on Rails to speed up page transition, and React.

> The panel is rendered with a random panel- class on each request, and the progress bar gets a random widthX class.
>
> With Turbolinks alone, the entire <body> would be replaced, and transitions would not happen. In this little demo though, React adds and removes classes and text, and the attribute changes are animated with CSS transitions. The DOM is otherwise left intact.

You may be thinking that it's expensive to react to changing data if there are a large number of nodes under an owner. The good news is that JavaScript is fast and `render()` methods tend to be quite simple, so in most applications this is extremely fast. Additionally, the bottleneck is almost always the DOM mutation and not JS execution and React will optimize this for you using batching and change detection.
However, sometimes you really want to have fine-grained control over your performance. In that case, simply override `shouldComponentUpdate()` to return false when you want React to skip processing of a subtree. See [the React reference docs](./reference.html) for more information.

Every project uses a different system for building and deploying JavaScript. We've tried to make React as environment-agnostic as possible.
## React
## CDN-hosted React
### CDN-hosted React
We provide CDN-hosted versions of React [on our download page](/react/downloads.html). These prebuilt files use the UMD module format. Dropping them in with a simple `<script>` tag will inject a `React` global into your environment. It should also work out-of-the-box in CommonJS and AMD environments.
## Using master
### Using master
We have instructions for building from `master` [in our GitHub repository](https://github.com/facebook/react). We build a tree of CommonJS modules under `build/modules` which you can drop into any environment or packaging tool that supports CommonJS.

### In-browser JSX Transform
If you like using JSX, we provide an in-browser JSX transformer for development [on our download page](/react/downloads.html). Simply include a `<script type="text/jsx">` tag to engage the JSX transformer. Be sure to include the `/** @jsx React.DOM */` comment as well, otherwise the transformer will not run the transforms.

## Productionizing: Precompiled JSX
### Productionizing: Precompiled JSX
If you have [npm](http://npmjs.org/), you can simply run `npm install -g react-tools` to install our command-line `jsx` tool. This tool will translate files that use JSX syntax to plain JavaScript files that can run directly in the browser. It will also watch directories for you and automatically transform files when they are changed; for example: `jsx --watch src/ build/`. Run `jsx --help` for more information on how to use this tool.
## Helpful Open-Source Projects
### Helpful Open-Source Projects
The open-source community has built tools that integrate JSX with several build systems.
* [reactify](https://github.com/andreypopp/reactify) - use JSX with [browserify](http://browserify.org/).

## API
### React
`React` is the entry point to the React framework. If you're using one of the prebuilt packages it's available as a global; if you're using CommonJS modules you can `require()` it.
#### React.DOM
`React.DOM` provides all of the standard HTML tags needed to build a React app. You generally don't use it directly; instead, just include it as part of the `/** @jsx React.DOM */` docblock.
#### React.initializeTouchEvents
```javascript
initializeTouchEvents(boolean shouldUseTouch)
```
Configure React's event system to handle touch events on mobile devices.
#### React.createClass
```javascript
function createClass(object specification)
```
Creates a component given a specification. A component implements a `render` method which returns **one single** child. That child may have an arbitrarily deep child structure. One thing that makes components different than standard prototypal classes is that you don't need to call new on them. They are convenience wrappers that construct backing instances (via new) for you.
#### React.renderComponent
```javascript
ReactComponent renderComponent(ReactComponent container, DOMElement container)
```
Renders a React component into the DOM in the supplied `container`.
If the React component was previously rendered into `container`, this will perform an update on it and only mutate the DOM as necessary to reflect the latest React component.
#### React.unmountAndReleaseReactRootNode
```javascript
unmountAndReleaseReactRootNode(DOMElement container)
```
Remove a mounted React component from the DOM and clean up its event handlers and state.
#### React.renderComponentToString
```javascript
renderComponentToString(ReactComponent component, function callback)
```
Render a component to its initial HTML. This should only be used on the server. React will call `callback` with an HTML string when the markup is ready. You can use this method to create static site generators, or you can generate HTML on the server and send it down to have a very fast initial page load. If you call `React.renderComponent()` on a node that already has this server-rendered markup, React will preserve it and only attach event handlers, allowing you to have a very performant first-load experience.
### AbstractEvent
Your event handlers will be passed instances of `AbstractEvent`, a cross-browser wrapper around the browser's native event. It has the same interface as the browser's native event (such as `stopPropagation()` and `preventDefault()`) except they work exactly the same across all browsers.
If you find that you need the underlying browser event for some reason, simply use the `nativeEvent` attribute to get it.
### ReactComponent
Component classses created by `createClass()` return instances of `ReactComponent` when called. Most of the time when you're using React you're either creating or consuming `ReactComponent`s.
#### getDOMNode
```javascript
DOMElement getDOMNode()
```
If this component has been mounted into the DOM, this returns the corresponding native browser DOM element. This method is useful for reading values out of the DOM, such as form field values and performing DOM measurements.
#### setProps
```javascript
setProps(object nextProps)
```
When you're integrating with an external JavaScript application you may want to signal a change to a React component rendered with `renderComponent()`. Simply call `setProps()` to change its properties and trigger a re-render.
> Note:
>
> This method can only be called on a root-level component. That is, it's only available on the component passed directly to `renderComponent()` and none of its children. If you're inclined to use `setProps()` on a child component, instead take advantage of reactive updates and pass the new prop to the child component when it's created in `render()`.
#### replaceProps
```javascript
replaceProps(object nextProps)
```
Like `setProps()` but deletes any pre-existing props that are not in nextProps.
#### transferPropsTo
```javascript
ReactComponent transferPropsTo(ReactComponent targetComponent)
```
Transfer properties from this component to a target component that have not already been set on the target component. This is usually used to pass down properties to the returned root component. `targetComponent`, now updated with some new props is returned as a convenience.
#### setState
```javascript
setState(object nextState[, function callback])
```
Merges nextState with the current state. This is the primary method you use to trigger UI updates from event handlers and server request callbacks. In addition, you can supply an optional callback function that is executed once `setState` is completed.
> Note:
>
> *NEVER* mutate `this.state` directly. As calling `setState()` afterwards may replace the mutation you made. Treat `this.state` as if it were immutable.
> Note:
>
> `setState()` does not immediately mutate `this.state` but creates a pending state transition. Accessing `this.state` after calling this method can potentially return the existing value.
> Note:
>
> There is no guarantee of synchronous operation of calls to `setState` and calls may be batched for performance gains.
#### replaceState
```javascript
replaceState(object nextState[, function callback])
```
Like `setState()` but deletes any pre-existing state keys that are not in nextState.
#### forceUpdate()
```javascript
forceUpdate([function callback])
```
If your `render()` method reads from something other than `this.props` or `this.state` you'll need to tell React when it needs to re-run `render()`. Use `forceUpdate()` to cause React to automatically re-render. This will cause `render()` to be called on the component and all of its children but React will only update the DOM if the markup changes.
Normally you should try to avoid all uses of `forceUpdate()` and only read from `this.props` and `this.state` in `render()`. This makes your application much simpler and more efficient.
> Note:
>
> There is no guarantee of synchronous operation of calls to `forceUpdate` and calls may be batched for performance gains.
#### Lifecycle methods
```javascript
object getInitialState()
componentWillMount()
componentDidMount(DOMElement domNode)
componentWillReceiveProps(object nextProps)
boolean shouldComponentUpdate(object nextProps, object nextState)
componentWillUpdate(object nextProps, object nextState)
ReactComponent render()
componentDidUpdate(object prevProps, object prevState, DOMElement domNode)
componentWillUnmount()
```
See the [working with the browser](./working-with-the-browser.html) documentation for more details on these lifecycle methods.
## DOM Differences
React has implemented a browser-independent events and DOM system for performance and cross-browser compatibility reasons. We took the opportunity to clean up a few rough edges in browser DOM implementations.
* All events (including submit) bubble correctly per the W3C spec
* All event objects conform to the W3C spec
* All DOM properties and attributes (including event handlers) should be camelCased to be consistent with standard JavaScript style. We intentionally break with the spec here, since the spec is inconsistent.
* The `style` attribute accepts a JavaScript object with camelCased properties rather than a CSS string. This is consistent with the DOM `style` JavaScript property, is more efficient, and prevents XSS security holes.
* `onChange` behaves as you would expect it to: whenever a form field is changed this event is fired rather than inconsistently on blur. We intentionally break from existing browser behavior because `onChange` is a misnomer for its behavior and React relies on this event to react to user input in real time.

[function callback]
)
```
Renders a React component into the DOM in the supplied `container`.
If the React component was previously rendered into `container`, this will perform an update on it and only mutate the DOM as necessary to reflect the latest React component.

Transfer properties from this component to a target component that have not already been set on the target component. After the props are updated, `targetComponent` is returned as a convenience. This function is useful when creating simple HTML-like components:
```javascript
var Avatar = React.createClass({
render: function() {
return this.transferPropsTo(
<img src={"/avatars/" + this.props.userId + ".png"} userId={null} />
);
}
});
// <AvatarImage userId={17} width={200} height={200} />
```
Properties that are specified directly on the target component instance (such as `src` and `userId` in the above example) will not be overwritten by `transferPropsTo`.
> Note:
>
> Use `transferPropsTo` with caution; it encourages tight coupling and makes it easy to accidentally introduce implicit dependencies between components. When in doubt, it's safer to explicitly copy the properties that you need onto the child component.

Merges nextState with the current state. This is the primary method you use to trigger UI updates from event handlers and server request callbacks. In addition, you can supply an optional callback function that is executed once `setState` is completed.

## Component Specifications
When creating a component class by invoking `React.createClass()`, you should provide a specification object that contains a `render` method and can optionally contain other lifecycle methods described here.
### render
```javascript
ReactComponent render()
```
The `render()` method is required.
When called, it should examine `this.props` and `this.state` and return a single child component. This child component can be either a native DOM component (such as `<div>`) or another composite component that you've defined yourself.
The `render()` function should be *pure*, meaning that it does not modify component state, it returns the same result each time it's invoked, and it does not read from or write to the DOM or otherwise interact with the browser (e.g., by using `setTimeout`). If you need to interact with the browser, perform your work in `componentDidMount()` or the other lifecycle methods instead. Keeping `render()` pure makes server rendering more practical and makes components easier to think about.
### getInitialState
```javascript
object getInitialState()
```
Invoked once when the component is mounted. The return value will be used as the initial value of `this.state`.
### getDefaultProps
```javascript
object getDefaultProps()
```
Invoked once when the component is mounted. Values in the mapping will be set on `this.props` if that prop is not specified by the parent component (i.e. using an `in` check).
This method is invoked before `getInitialState` and therefore cannot rely on `this.state` or use `this.setState`.
### propTypes
```javascript
object propTypes
```
The `propTypes` object allows you to validate props being passed to your components. For more information about `propTypes`, see [Reusable Components](reusable-components.html).
<!-- TODO: Document propTypes here directly. -->
### mixins
```javascript
array mixins
```
The `mixins` array allows you to use mixins to share behavior among multiple components. For more information about mixins, see [Reusable Components](reusable-components.html).
<!-- TODO: Document mixins here directly. -->
## Lifecycle Methods
Various methods are executed at specific points in a component's lifecycle.
### Mounting: componentWillMount
```javascript
componentWillMount()
```
Invoked immediately before rendering occurs. If you call `setState` within this method, `render()` will see the updated state and will be executed only once despite the state change.
### Mounting: componentDidMount
```javascript
componentDidMount(DOMElement rootNode)
```
Invoked immediately after rendering occurs. At this point in the lifecycle, the component has a DOM representation which you can access via the `rootNode` argument or by calling `this.getDOMNode()`.
If you want to integrate with other JavaScript frameworks, set timers using `setTimeout` or `setInterval`, or send AJAX requests, perform those operations in this method.
### Updating: componentWillReceiveProps
```javascript
componentWillReceiveProps(object nextProps)
```
Invoked when a component is receiving new props. This method is not called for the initial render.
Use this as an opportunity to react to a prop transition before `render()` is called by updating the state using `this.setState()`. The old props can be accessed via `this.props`. Calling `this.setState()` within this function will not trigger an additional render.
```javascript
componentWillReceiveProps: function(nextProps) {
this.setState({
likesIncreasing: nextProps.likeCount > this.props.likeCount
});
}
```
> Note:
>
> There is no analogous method `componentWillReceiveState`. An incoming prop transition may cause a state change, but the opposite is not true. If you need to perform operations in response to a state change, use `componentWillUpdate`.
### Updating: shouldComponentUpdate
```javascript
boolean shouldComponentUpdate(object nextProps, object nextState)
```
Invoked before rendering when new props or state are being received. This method is not called for the initial render or when `forceUpdate` is used.
Use this as an opportunity to `return false` when you're certain that the
transition to the new props and state will not require a component update.
```javascript
shouldComponentUpdate: function(nextProps, nextState) {
return !equal(nextProps, this.props) || !equal(nextState, this.state);
}
```
If `shouldComponentUpdate` returns false, then `render()` will be completely skipped until the next state change. (In addition, `componentWillUpdate` and `componentDidUpdate` will not be called.)
By default, `shouldComponentUpdate` always returns true to prevent subtle bugs when `state` is mutated in place, but if you are careful to always treat `state` as immutable and to read only from `props` and `state` in `render()` then you can override `shouldComponentUpdate` with an implementation that compares the old props and state to their replacements.
If performance is a bottleneck, especially with dozens or hundreds of components, use `shouldComponentUpdate` to speed up your app.
### Updating: componentWillUpdate
```javascript
componentWillUpdate(object nextProps, object nextState)
```
Invoked immediately before rendering when new props or state are being received. This method is not called for the initial render.
Use this as an opportunity to perform preparation before an update occurs.
> Note:
>
> You *cannot* use `this.setState()` in this method. If you need to update state in response to a prop change, use `componentWillReceiveProps` instead.
### Updating: componentDidUpdate
```javascript
componentDidUpdate(object prevProps, object prevState, DOMElement rootNode)
```
Invoked immediately after updating occurs. This method is not called for the initial render.
Use this as an opportunity to operate on the DOM when the component has been updated.
### Unmounting: componentWillUnmount
```javascript
componentWillUnmount()
```
Invoked immediately before a component is unmounted from the DOM.
Perform any necessary cleanup in this method, such as invalidating timers or cleaning up any DOM elements that were created in `componentDidMount`.

Your event handlers will be passed instances of `SyntheticEvent`, a cross-browser wrapper around the browser's native event. It has the same interface as the browser's native event, including `stopPropagation()` and `preventDefault()`, except the events work identically across all browsers.
If you find that you need the underlying browser event for some reason, simply use the `nativeEvent` attribute to get it. Every `SyntheticEvent` object has the following attributes:
```javascript
boolean bubbles

React has implemented a browser-independent events and DOM system for performance and cross-browser compatibility reasons. We took the opportunity to clean up a few rough edges in browser DOM implementations.
* All DOM properties and attributes (including event handlers) should be camelCased to be consistent with standard JavaScript style. We intentionally break with the spec here since the spec is inconsistent.
* The `style` attribute accepts a JavaScript object with camelCased properties rather than a CSS string. This is consistent with the DOM `style` JavaScript property, is more efficient, and prevents XSS security holes.
* All event objects conform to the W3C spec, and all events (including submit) bubble correctly per the W3C spec. See [Event System](events.html) for more details.
* The `onChange` event behaves as you would expect it to: whenever a form field is changed this event is fired rather than inconsistently on blur. We intentionally break from existing browser behavior because `onChange` is a misnomer for its behavior and React relies on this event to react to user input in real time. See [Forms](forms.html) for more details.
