fb7e157cba Make doc headers clickable again
...without preventing clicks on other things.

Just use an `<a name="...">` tag that doesn't take up any space to make sure that we're not covering up something else.

For whatever reason, doing `position: relative; top: -$navHeight;` doesn't work and causes the anchor target not to be moved up. This solution works in both Chrome and Firefox.

fb1a072739 fix doc & example transition opacity from .99 to 1
The initial thought was that an opacity animation from 0.01 to 1 causes trouble on some browser. But after testing on opera 12.15, ff 23, ie 10, chrome 30, desktop/mobile safari 7 and chrome android I confirm this works.

e5f03ae407 tutorial: Simplify ajax options
dataType was unnecessary; mimeType was both unnecessary and wrong in this case. Also removed an unnecessary bind and changed pollInterval to 2000 ms for consistency with https://github.com/petehunt/react-tutorial (faster is nicer if you actually try it out!).

b21cdac9e3 Move heading anchors 50px up to avoid nav bar
Fixes #447.

We do this by moving the actual anchored element up in the page without moving the actual text. (Apple uses a similar trick in their framed docs.) Now this looks a bit sillier on smaller screens but it's better overall.

ef4d7a37f0 npm shrinkwrap
We should be doing this in the stable branch to ensure fuzzy
dependencies are met identically on subsequent releases.

In this case, browserify had a change in 2.34.3 which resulted in
JSXTransformer to be a different size. While it was a change for the
better, it was unexpected and not a change we were calling out in the
release.

This shrinkwraps to the same versions of packages we had when we shipped
0.5.0.

7b957c880c Fix unmounting components mounted into doc element
If we are to unmount a component mounted into a document element we should
unmount it from document.documentElement and not from document.firstChild which
is a doctype element in this specific case.

ce612904ef Make SelectEventPlugin not throw for range inputs
Accessing .selectionStart on a non-text input will throw (see http://www.w3.org/TR/2009/WD-html5-20090423/editing.html#textFieldSelection), so check that the input has selection capabilities before accessing the property.

Fixes #437.

## 0.9.0 (February 20, 2014)
### React Core
#### Breaking Changes
- The lifecycle methods `componentDidMount` and `componentDidUpdate` no longer receive the root node as a parameter; use `this.getDOMNode()` instead
- Whenever a prop is equal to `undefined`, the default value returned by `getDefaultProps` will now be used instead
- `React.unmountAndReleaseReactRootNode` was previously deprecated and has now been removed
- `React.renderComponentToString` is now synchronous and returns the generated HTML string
- Full-page rendering (that is, rendering the `<html>` tag using React) is now supported only when starting with server-rendered markup
- On mouse wheel events, `deltaY` is no longer negated
- When prop types validation fails, a warning is logged instead of an error thrown (with the production build of React, type checks are now skipped for performance)
- On `input`, `select`, and `textarea` elements, `.getValue()` is no longer supported; use `.getDOMNode().value` instead
- `this.context` on components is now reserved for internal use by React
#### New Features
- React now never rethrows errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly
- Added support for SVG tags `defs`, `linearGradient`, `polygon`, `radialGradient`, `stop`
- Added support for more attributes:
- `crossOrigin` for CORS requests
- `download` and `hrefLang` for `<a>` tags
- `mediaGroup` and `muted` for `<audio>` and `<video>` tags
- `noValidate` and `formNoValidate` for forms
- `property` for Open Graph `<meta>` tags
- `sandbox`, `seamless`, and `srcDoc` for `<iframe>` tags
- `scope` for screen readers
- `span` for `<colgroup>` tags
- Added support for defining `propTypes` in mixins
- Added `any`, `arrayOf`, `component`, `oneOfType`, `renderable`, `shape` to `React.PropTypes`
- Added support for `statics` on component spec for static component methods
- On all events, `.currentTarget` is now properly set
- On keyboard events, `.key` is now polyfilled in all browsers for special (non-printable) keys
- On clipboard events, `.clipboardData` is now polyfilled in IE
- On drag events, `.dragTransfer` is now present
- Added support for `onMouseOver` and `onMouseOut` in addition to the existing `onMouseEnter` and `onMouseLeave` events
- Added support for `onLoad` and `onError` on `<img>` elements
- Added support for `onReset` on `<form>` elements
- The `autoFocus` attribute is now polyfilled consistently on `input`, `select`, and `textarea`
#### Bug Fixes
- React no longer adds an `__owner__` property to each component's `props` object; passed-in props are now never mutated
- When nesting top-level components (e.g., calling `React.renderComponent` within `componentDidMount`), events now properly bubble to the parent component
- Fixed a case where nesting top-level components would throw an error when updating
- Passing an invalid or misspelled propTypes type now throws an error
- On mouse enter/leave events, `.target`, `.relatedTarget`, and `.type` are now set properly
- On composition events, `.data` is now properly normalized in IE9 and IE10
- CSS property values no longer have `px` appended for the unitless properties `columnCount`, `flex`, `flexGrow`, `flexShrink`, `lineClamp`, `order`, `widows`
- Fixed a memory leak when unmounting children with a `componentWillUnmount` handler
- Fixed a memory leak when `renderComponentToString` would store event handlers
- Fixed an error that could be thrown when removing form elements during a click handler
- Boolean attributes such as `disabled` are rendered without a value (previously `disabled="true"`, now simply `disabled`)
- `key` values containing `.` are now supported
- Shortened `data-reactid` values for performance
- Components now always remount when the `key` property changes
- Event handlers are attached to `document` only when necessary, improving performance in some cases
- Events no longer use `.returnValue` in modern browsers, eliminating a warning in Chrome
- `scrollLeft` and `scrollTop` are no longer accessed on document.body, eliminating a warning in Chrome
- General performance fixes, memory optimizations, improvements to warnings and error messages
### React with Addons
- `React.addons.TestUtils` was added to help write unit tests
- `React.addons.TransitionGroup` was renamed to `React.addons.CSSTransitionGroup`
- `React.addons.TransitionGroup` was added as a more general animation wrapper
- `React.addons.cloneWithProps` was added for cloning components and modifying their props
- Bug fix for adding back nodes during an exit transition for CSSTransitionGroup
- Bug fix for changing `transitionLeave` in CSSTransitionGroup
- Performance optimizations for CSSTransitionGroup
- On checkbox `<input>` elements, `checkedLink` is now supported for two-way binding
### JSX Compiler and react-tools Package
- Whitespace normalization has changed; now space between two tags on the same line will be preserved, while newlines between two tags will be removed
- The `react-tools` npm package no longer includes the React core libraries; use the `react` package instead.
- `displayName` is now added in more cases, improving error messages and names in the React Dev Tools
- Fixed an issue where an invalid token error was thrown after a JSX closing tag
- `JSXTransformer` now uses source maps automatically in modern browsers
- `JSXTransformer` error messages now include the filename and problematic line contents when a file fails to parse
## 0.8.0 (December 19, 2013)
### React
* Added support for more attributes:
* `rows` & `cols` for `<textarea>`
* `defer` & `async` for `<script>`
* `loop` for `<audio>` & `<video>`
* `autoCorrect` for form fields (a non-standard attribute only supported by mobile WebKit)
* Improved error messages
* Fixed Selection events in IE11
* Added `onContextMenu` events
### React with Addons
* Fixed bugs with TransitionGroup when children were undefined
* Added support for `onTransition`
### react-tools
* Upgraded `jstransform` and `esprima-fb`
### JSXTransformer
* Added support for use in IE8
* Upgraded browserify, which reduced file size by ~65KB (16KB gzipped)
## 0.5.2, 0.4.2 (December 18, 2013)
### React
* Fixed a potential XSS vulnerability when using user content as a `key`: [CVE-2013-7035](https://groups.google.com/forum/#!topic/reactjs/OIqxlB2aGfU)
## 0.5.1 (October 29, 2013)

To build a static version of your app that renders your data model you'll want to build components that reuse other components and pass data using *props*. *props* are a way of passing data from parent to child. If you're familiar with the concept of *state*, **don't use state at all** to build this static version. State is reserved only for interactivity, that is, data that changes over time. Since this is a static version of the app you don't need it.

Today we're releasing an update to address a potential XSS vulnerability that can arise when using user data as a `key`. Typically "safe" data is used for a `key`, for example, an id from your database, or a unique hash. However there are cases where it may be reasonable to use user generated content. A carefully crafted piece of content could result in arbitrary JS execution. While we make a very concerted effort to ensure all text is escaped before inserting it into the DOM, we missed one case. Immediately following the discovery of this vulnerability, we performed an audit to ensure we this was the only such vulnerability.
This only affects v0.5.x and v0.4.x. Versions in the 0.3.x family are unaffected.
Updated versions are available for immediate download via npm, bower, and on our [download page][download].
We take security very seriously at Facebook. For most of our products, users don't need to know that a security issue has been fixed. But with libraries like React, we need to make sure developers using React have access to fixes to keep their users safe.
While we've encouraged responsible disclosure as part of [Facebook's whitehat bounty program][bounty] since we launched, we don't have a good process for notifying our users. Hopefully we don't need to use it, but moving forward we'll set up a little bit more process to ensure the safety of our users. Ember.js has [an excellent policy][ember] which we may use as our model.
You can learn more about the vulnerability discussed here: [CVE-2013-7035][cve].

title: "React v0.8"
layout: post
author: Paul O'Shannessy

I'll start by answering the obvious question:
> What happened to 0.6 and 0.7?
It's become increasingly obvious since our launch in May that people want to use React on the server. With the server-side rendering abilities, that's a perfect fit. However using the same copy of React on the server and then packaging it up for the client is surprisingly a harder problem. People have been using our `react-tools` module which includes React, but when browserifying that ends up packaging all of `esprima` and some other dependencies that aren't needed on the client. So we wanted to make this whole experience better.
We talked with [Jeff Barczewski][jeff] who was the owner of the `react` module on npm. He was kind enough to transition ownership to us and release his package under a different name: `autoflow`. I encourage you to [check it out][autoflow] if you're writing a lot of asynchronous code. In order to not break all of `react`'s current users of 0.7.x, we decided to bump our version to 0.8 and skip the issue entirely. We're also including a warning if you use our `react` module like you would use the previous package.
In order to make the transition to 0.8 for our current users as painless as possible, we decided to make 0.8 primarily a bug fix release on top of 0.5. No public APIs were changed (even if they were already marked as deprecated). We haven't added any of the new features we have in master, though we did take the opportunity to pull in some improvements to internals.
We hope that by releasing `react` on npm, we will enable a new set of uses that have been otherwise difficult. All feedback is welcome!
## Changelog
### React
* Added support for more attributes:
* `rows` & `cols` for `<textarea>`
* `defer` & `async` for `<script>`
* `loop` for `<audio>` & `<video>`
* `autoCorrect` for form fields (a non-standard attribute only supported by mobile WebKit)
* Improved error messages
* Fixed Selection events in IE11
* Added `onContextMenu` events
### React with Addons
* Fixed bugs with TransitionGroup when children were undefined
* Added support for `onTransition`
### react-tools
* Upgraded `jstransform` and `esprima-fb`
### JSXTransformer
* Added support for use in IE8
* Upgraded browserify, which reduced file size by ~65KB (16KB gzipped)

React got featured on the front-page of Hacker News thanks to the Om library. If you try it out for the first time, take a look at the [docs](/react/docs/getting-started.html) and do not hesitate to ask questions on the [Google Group](http://groups.google.com/group/reactjs), [IRC](irc://chat.freenode.net/reactjs) or [Stack Overflow](http://stackoverflow.com/questions/tagged/reactjs). We are trying our best to help you out!
## The Future of Javascript MVC
[David Nolen](http://swannodette.github.io/) announced Om, a thin wrapper on-top of React in ClojureScript. It stands out by only using immutable data structures. This unlocks the ability to write a very efficient [shouldComponentUpdate](http://facebook.github.io/react/docs/component-specs.html#updating-shouldcomponentupdate) and get huge performance improvements on some tasks.
> We've known this for some time over here in the ClojureScript corner of the world - all of our collections are immutable and modeled directly on the original Clojure versions written in Java. Modern JavaScript engines have now been tuned to the point that it's no longer uncommon to see collection performance within 2.5X of the Java Virtual Machine.
>
> Wait, wait, wait. What does the performance of persistent data structures have to do with the future of JavaScript MVCs?

> A whole lot.

## Scroll Position with React
Managing the scroll position when new content is inserted is usually very tricky to get right. [Vjeux](http://blog.vjeux.com/) discovered that [componentWillUpdate](http://facebook.github.io/react/docs/component-specs.html#updating-componentwillupdate) and [componentDidUpdate](http://facebook.github.io/react/docs/component-specs.html#updating-componentdidupdate) were triggered exactly at the right time to manage the scroll position.
> We can check the scroll position before the component has updated with componentWillUpdate and scroll if necessary at componentDidUpdate
>
> ```
componentWillUpdate: function() {
var node = this.getDOMNode();
this.shouldScrollBottom =
(node.scrollTop + node.offsetHeight) === node.scrollHeight;
},
componentDidUpdate: function() {
if (this.shouldScrollBottom) {
var node = this.getDOMNode();
node.scrollTop = node.scrollHeight
}
},
```

React declarative approach is well suited to write games. [Cheng Lou](https://github.com/chenglou) wrote the famous Lights Out game in React. It's a good example of use of [TransitionGroup](http://facebook.github.io/react/docs/animation.html) to implement animations.

## Writing Good React Components
[William Högman Rudenmalm](http://blog.whn.se/) wrote an article on how to write good React components. This is full of good advice.
> The idea of dividing software into smaller parts or components is hardly new - It is the essance of good software. The same principles that apply to software in general apply to building React components. That doesnt mean that writing good React components is just about applying general rules.
>
> The web offers a unique set of challenges, which React offers interesting solutions to. First and foremost among these solutions is the what is called the Mock DOM. Rather than having user code interface with the DOM in a direct fashion, as is the case with most DOM manipulation libraries.
>
> You build a model of how you want the DOM end up like. React then inserts this model into the DOM. This is very useful for updates because React simply compares the model or mock DOM against the actual DOM, and then only updates based on the difference between the two states.

## React + Socket.io
[Geert Pasteels](http://enome.be/nl) made a small experiment with Socket.io. He wrote a very small mixin that synchronizes React state with the server. Just include this mixin to your React component and it is now live!
```javascript
changeHandler: function (data) {
if (!_.isEqual(data.state, this.state) && this.path === data.path) {
this.setState(data.state);
}
},
componentDidMount: function (root) {
this.path = utils.nodePath(root);
socket.on('component-change', this.changeHandler);
},
componentWillUpdate: function (props, state) {
socket.emit('component-change', { path: this.path, state: state });
},

> Rendering this takes 803ms for 10 iterations, hovering around 35 and 55ms for each data reload (that's 67% faster). You'll notice that the first load takes a little longer than successive loads, and the second load REALLY struggles - here, it's 433ms, which is more than half of the total time!

title: "React Chrome Developer Tools"

With the new year, we thought you'd enjoy some new tools for debugging React code. Today we're releasing the [React Developer Tools](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi), an extension to the Chrome Developer Tools. [Download them from the Chrome Web Store](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi).
<figure><iframe width="560" height="315" src="//www.youtube.com/embed/Cey7BS6dE0M" frameborder="0" allowfullscreen></iframe></figure>
You will get a new tab titled "React" in your Chrome DevTools. This tab shows you a list of the root React Components that are rendered on the page as well as the subcomponents that each root renders.
Selecting a Component in this tab allows you to view and edit its props and state in the panel on the right. In the breadcrumbs at the bottom, you can inspect the selected Component, the Component that created it, the Component that created that one, and so on.
When you inspect a DOM element using the regular Elements tab, you can switch over to the React tab and the corresponding Component will be automatically selected. The Component will also be automatically selected if you have a breakpoint within its render phase. This allows you to step through the render tree and see how one Component affects another one.
<figure>[![](/react/img/blog/react-dev-tools.jpg)](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi)</figure>
We hope these tools will help your team better understand your component hierarchy and track down bugs. We're very excited about this initial launch and appreciate any feedback you may have. As always, we also accept [pull requests on GitHub](https://github.com/facebook/react-devtools).

## React Baseline
React is only one-piece of your web application stack. [Mark Lussier](https://github.com/intabulas) shared his baseline stack that uses React along with Grunt, Browserify, Bower, Zepto, Director and Sass. This should help you get started using React for a new project.

Interest in React seems to have surged ever since David Nolen ([@swannodette](https://twitter.com/swannodette))'s introduction of [Om](https://github.com/swannodette/om) in his post ["The Future of Javascript MVC Frameworks"](http://swannodette.github.io/2013/12/17/the-future-of-javascript-mvcs/).
In this React Community Round-up, we are taking a closer look at React from a functional programming perspective.
## "React: Another Level of Indirection"
To start things off, Eric Normand ([@ericnormand](https://twitter.com/ericnormand)) of [LispCast](http://lispcast.com) makes the case for [React from a general functional programming standpoint](http://www.lispcast.com/react-another-level-of-indirection) and explains how React's "Virtual DOM provides the last piece of the Web Frontend Puzzle for ClojureScript".
> The Virtual DOM is an indirection mechanism that solves the difficult problem of DOM programming: how to deal with incremental changes to a stateful tree structure. By abstracting away the statefulness, the Virtual DOM turns the real DOM into an immediate mode GUI, which is perfect for functional programming.

## Reagent: Minimalistic React for ClojureScript
Dan Holmsand ([@holmsand](https://twitter.com/holmsand)) created [Reagent](http://holmsand.github.io/reagent/), a simplistic ClojureScript API to React.
> It allows you to define efficient React components using nothing but plain ClojureScript functions and data, that describe your UI using a Hiccup-like syntax.
>
> The goal of Reagent is to make it possible to define arbitrarily complex UIs using just a couple of basic concepts, and to be fast enough by default that you rarely have to care about performance.
>
> [Check it out on Github...](http://holmsand.github.io/reagent/)
## Functional DOM programming
React's one-way data-binding naturally lends itself to a functional programming approach. Facebook's Pete Hunt ([@floydophone](https://twitter.com/floydophone)) explores how one would go about [writing web apps in a functional manner](https://medium.com/p/67d81637d43). Spoiler alert:
> This is React. Its not about templates, or data binding, or DOM manipulation. Its about using functional programming with a virtual DOM representation to build ambitious, high-performance apps with JavaScript.
>
> [Read the full post...](https://medium.com/p/67d81637d43)
Pete also explains this in detail at his #MeteorDevShop talk (about 30 Minutes):

## Kioo: Separating markup and logic
[Creighton Kirkendall](https://github.com/ckirkendall) created [Kioo](https://github.com/ckirkendall/kioo), which adds Enlive-style templating to React. HTML templates are separated from the application logic. Kioo comes with separate examples for both Om and Reagent.
A basic example from github:
```html
<!DOCTYPE html>
<html lang="en">

## Om
In an interview with David Nolen, Tom Coupland ([@tcoupland](https://twitter.com/tcoupland)) of InfoQ provides a nice summary of recent developments around Om ("[Om: Enhancing Facebook's React with Immutability](http://www.infoq.com/news/2014/01/om-react)").
> David [Nolen]: I think people are starting to see the limitations of just JavaScript and jQuery and even more structured solutions like Backbone, Angular, Ember, etc. React is a fresh approach to the DOM problem that seems obvious in hindsight.

### A slice of React, ClojureScript and Om
Fredrik Dyrkell ([@lexicallyscoped](https://twitter.com/lexicallyscoped)) rewrote part of the [React tutorial in both ClojureScript and Om](http://www.lexicallyscoped.com/2013/12/25/slice-of-reactjs-and-cljs.html), along with short, helpful explanations.
> React has sparked a lot of interest in the Clojure community lately [...]. At the very core, React lets you build up your DOM representation in a functional fashion by composing pure functions and you have a simple building block for everything: React components.
>
> [Read the full post...](http://www.lexicallyscoped.com/2013/12/25/slice-of-reactjs-and-cljs.html)
In a separate post, Dyrkell breaks down [how to build a binary clock component](http://www.lexicallyscoped.com/2014/01/23/ClojureScript-react-om-binary-clock.html) in Om.
[[Demo](http://www.lexicallyscoped.com/demo/binclock/)] [[Code](https://github.com/fredyr/binclock/blob/master/src/binclock/core.cljs)]
### Time Travel: Implementing undo in Om
David Nolen shows how to leverage immutable data structures to [add global undo](http://swannodette.github.io/2013/12/31/time-travel/) functionality to an app using just 13 lines of ClojureScript.
### A Step-by-Step Om Walkthrough
[Josh Lehman](http://www.joshlehman.me) took the time to create an extensive [step-by-step walkthrough](http://www.joshlehman.me/rewriting-the-react-tutorial-in-om/) of the React tutorial in Om. The well-documented source is on [github](https://github.com/jalehman/omtut-starter).
### Omkara
[brendanyounger](https://github.com/brendanyounger) created [omkara](https://github.com/brendanyounger/omkara), a starting point for ClojureScript web apps based on Om/React. It aims to take advantage of server-side rendering and comes with a few tips on getting started with Om/React projects.
### Om Experience Report
Adam Solove ([@asolove](https://twitter.com/asolove/)) [dives a little deeper into Om, React and ClojureScript](http://adamsolove.com/js/clojure/2014/01/06/om-experience-report.html). He shares some helpful tips he gathered while building his [CartoCrayon](https://github.com/asolove/carto-crayon) prototype.
## Not-so-random Tweet
<div><blockquote class="twitter-tweet" lang="en"><p>[@swannodette](https://twitter.com/swannodette) No thank you! It's honestly a bit weird because Om is exactly what I didn't know I wanted for doing functional UI work.</p>&mdash; Adam Solove (@asolove) <a href="https://twitter.com/asolove/status/420294067637858304">January 6, 2014</a></blockquote></div>

title: "Community Round-up #16"
layout: post
author: Jonas Gebhardt
---
There have been many posts recently covering the <i>why</i> and <i>how</i> of React. This week's community round-up includes a collection of recent articles to help you get started with React, along with a few posts that explain some of the inner workings.
## React in a nutshell
Got five minutes to pitch React to your coworkers? John Lynch ([@johnrlynch](https://twitter.com/johnrlynch)) put together [this excellent and refreshing slideshow](http://slid.es/johnlynch/reactjs):
<iframe src="//slid.es/johnlynch/reactjs/embed" width="576" height="420" scrolling="no" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
## React's diff algorithm
React core team member Christopher Chedeau ([@vjeux](https://twitter.com/vjeux)) explores the innards of React's tree diffing algorithm in this [extensive and well-illustrated post](http://calendar.perfplanet.com/2013/diff/). <figure>[![](/react/img/blog/react-diff-tree.png)](http://calendar.perfplanet.com/2013/diff/)</figure>
While we're talking about tree diffing: Matt Esch ([@MatthewEsch](https://twitter.com/MatthewEsch)) created [this project](https://github.com/Matt-Esch/virtual-dom), which aims to implement the virtual DOM and a corresponding diff algorithm as separate modules.
## Many, many new introductions to React!
James Padosley wrote a short post on the basics (and merits) of React: [What is React?](http://james.padolsey.com/javascript/what-is-react/)
> What I like most about React is that it doesn't impose heady design patterns and data-modelling abstractions on me. [...] Its opinions are so minimal and its abstractions so focused on the problem of the DOM, that you can merrily slap your design choices atop.
> [Read the full post...](http://james.padolsey.com/javascript/what-is-react/)
Taylor Lapeyre ([@taylorlapeyre](https://twitter.com/taylorlapeyre)) wrote another nice [introduction to React](http://words.taylorlapeyre.me/an-introduction-to-react).
> React expects you to do the work of getting and pushing data from the server. This makes it very easy to implement React as a front end solution, since it simply expects you to hand it data. React does all the other work.
> [Read the full post...](http://words.taylorlapeyre.me/an-introduction-to-react)
[This "Deep explanation for newbies"](http://www.webdesignporto.com/react-js-in-pure-javascript-facebook-library/?utm_source=echojs&utm_medium=post&utm_campaign=echojs) by [@ProJavaScript](https://twitter.com/ProJavaScript) explains how to get started building a React game without using the optional JSX syntax.
### React around the world
It's great to see the React community expand internationally. [This site](http://habrahabr.ru/post/189230/) features a React introduction in Russian.
### React tutorial series
[Christopher Pitt](https://medium.com/@followchrisp) explains [React Components](https://medium.com/react-tutorials/828c397e3dc8) and [React Properties](https://medium.com/react-tutorials/ef11cd55caa0). The former includes a nice introduction to using JSX, while the latter focuses on adding interactivity and linking multiple components together. Also check out the [other posts in his React Tutorial series](https://medium.com/react-tutorials), e.g. on using [React + Backbone Model](https://medium.com/react-tutorials/8aaec65a546c) and [React + Backbone Router](https://medium.com/react-tutorials/c00be0cf1592).
### Beginner tutorial: Implementing the board game Go
[Chris LaRose](http://cjlarose.com/) walks through the steps of creating a Go app in React, showing how to separate application logic from the rendered components. Check out his [tutorial](http://cjlarose.com/2014/01/09/react-board-game-tutorial.html) or go straight to the [code](https://github.com/cjlarose/react-go).
### Egghead.io video tutorials
Joe Maddalone ([@joemaddalone](https://twitter.com/joemaddalone)) of [egghead.io](https://egghead.io/) created a series of React video tutorials, such as [this](http://www.youtube.com/watch?v=rFvZydtmsxM&feature=youtu.be&a) introduction to React Components. [[part 1](http://www.youtube.com/watch?v=rFvZydtmsxM&feature=youtu.be&a)], [[part 2](http://www.youtube.com/watch?v=5yvFLrt7N8M)]
### "React: Finally, a great server/client web stack"
Eric Florenzano ([@ericflo](https://twitter.com/ericflo)) sheds some light on what makes React perfect for server rendering:
> [...] the ideal solution would fully render the markup on the server, deliver it to the client so that it can be shown to the user instantly. Then it would asynchronously load some Javascript that would attach to the rendered markup, and invisibly promote the page into a full app that can render its own markup. [...]
> What I've discovered is that enough of the pieces have come together, that this futuristic-sounding web environment is actually surprisingly easy to do now with React.js.
> [Read the full post...](http://eflorenzano.com/blog/2014/01/23/react-finally-server-client/)
## Building a complex React component
[Matt Harrison](http://matt-harrison.com/) walks through the process of [creating an SVG-based Resistance Calculator](http://matt-harrison.com/building-a-complex-web-component-with-facebooks-react-library/) using React. <figure>[![](/react/img/blog/resistance-calculator.png)](http://matt-harrison.com/building-a-complex-web-component-with-facebooks-react-library/)</figure>

title: React v0.9 RC
layout: post
author: Ben Alpert
---
We're almost ready to release React v0.9! We're posting a release candidate so that you can test your apps on it; we'd much prefer to find show-stopping bugs now rather than after we release.
The release candidate is available for download from the CDN:
* **React**
Dev build with warnings: <http://fb.me/react-0.9.0-rc1.js>
Minified build for production: <http://fb.me/react-0.9.0-rc1.min.js>
* **React with Add-Ons**
Dev build with warnings: <http://fb.me/react-with-addons-0.9.0-rc1.js>
Minified build for production: <http://fb.me/react-with-addons-0.9.0-rc1.min.js>
* **In-Browser JSX transformer**
<http://fb.me/JSXTransformer-0.9.0-rc1.js>
We've also published version `0.9.0-rc1` of the `react` and `react-tools` packages on npm and the `react` package on bower.
Please try these builds out and [file an issue on GitHub](https://github.com/facebook/react/issues/new) if you see anything awry.
## Upgrade Notes
In addition to the changes to React core listed below, we've made a small change to the way JSX interprets whitespace to make things more consistent. With this release, space between two components on the same line will be preserved, while a newline separating a text node from a tag will be eliminated in the output. Consider the code:
```html
<div>
Monkeys:
{listOfMonkeys} {submitButton}
</div>
```
In v0.8 and below, it was transformed to the following:
```javascript
React.DOM.div(null,
" Monkeys: ",
listOfMonkeys, submitButton
)
```
In v0.9, it will be transformed to this JS instead:
```javascript{2,3}
React.DOM.div(null,
"Monkeys:",
listOfMonkeys, " ", submitButton
)
```
We believe this new behavior is more helpful and elimates cases where unwanted whitespace was previously added.
In cases where you want to preserve the space adjacent to a newline, you can write a JS string like `{"Monkeys: "}` in your JSX source. We've included a script to do an automated codemod of your JSX source tree that preserves the old whitespace behavior by adding and removing spaces appropriately. You can [install jsx\_whitespace\_transformer from npm](https://github.com/facebook/react/blob/master/npm-jsx_whitespace_transformer/README.md) and run it over your source tree to modify files in place. The transformed JSX files will preserve your code's existing whitespace behavior.
## Changelog
### React Core
#### Breaking Changes
- The lifecycle methods `componentDidMount` and `componentDidUpdate` no longer receive the root node as a parameter; use `this.getDOMNode()` instead
- Whenever a prop is equal to `undefined`, the default value returned by `getDefaultProps` will now be used instead
- `React.unmountAndReleaseReactRootNode` was previously deprecated and has now been removed
- `React.renderComponentToString` is now synchronous and returns the generated HTML string
- Full-page rendering (that is, rendering the `<html>` tag using React) is now supported only when starting with server-rendered markup
- On mouse wheel events, `deltaY` is no longer negated
- When prop types validation fails, a warning is logged instead of an error thrown (with the production build of React, the type checks are now skipped for performance)
- On `input`, `select`, and `textarea` elements, `.getValue()` is no longer supported; use `.getDOMNode().value` instead
- `this.context` on components is now reserved for internal use by React
#### New Features
- React now never rethrows errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly
- Added a new tool for profiling React components and identifying places where defining `shouldComponentUpdate` can give performance improvements
- Added support for SVG tags `defs`, `linearGradient`, `polygon`, `radialGradient`, `stop`

- `span` for `<colgroup>` tags
- Added support for defining `propTypes` in mixins
- Added `any`, `arrayOf`, `component`, `oneOfType`, `renderable`, `shape` to `React.PropTypes`
- Added support for `statics` on component spec for static component methods
- On all events, `.currentTarget` is now properly set
- On keyboard events, `.key` is now polyfilled in all browsers for special (non-printable) keys
- On clipboard events, `.clipboardData` is now polyfilled in IE
- On drag events, `.dataTransfer` is now present
- Added support for `onMouseOver` and `onMouseOut` in addition to the existing `onMouseEnter` and `onMouseLeave` events
- Added support for `onLoad` and `onError` on `<img>` elements

- The `autoFocus` attribute is now polyfilled consistently on `input`, `select`, and `textarea`
#### Bug Fixes
- React no longer adds an `__owner__` property to each component's `props` object; passed-in props are now never mutated
- When nesting top-level components (e.g., calling `React.renderComponent` within `componentDidMount`), events now properly bubble to the parent component
- Fixed a case where nesting top-level components would throw an error when updating
- Passing an invalid or misspelled propTypes type now throws an error
- On mouse enter/leave events, `.target`, `.relatedTarget`, and `.type` are now set properly
- On composition events, `.data` is now properly normalized in IE9 and IE10
- CSS property values no longer have `px` appended for the unitless properties `columnCount`, `flex`, `flexGrow`, `flexShrink`, `lineClamp`, `order`, `widows`
- Fixed a memory leak when unmounting children with a `componentWillUnmount` handler
- Fixed a memory leak when `renderComponentToString` would store event handlers
- Fixed an error that could be thrown when removing form elements during a click handler
- `key` values containing `.` are now supported
- Shortened `data-reactid` values for performance
- Components now always remount when the `key` property changes
- Event handlers are attached to `document` only when necessary, improving performance in some cases
- Events no longer use `.returnValue` in modern browsers, eliminating a warning in Chrome
- `scrollLeft` and `scrollTop` are no longer accessed on document.body, eliminating a warning in Chrome
- General performance fixes, memory optimizations, improvements to warnings and error messages
### React with Addons
- `React.addons.TransitionGroup` was renamed to `React.addons.CSSTransitionGroup`
- `React.addons.TransitionGroup` was added as a more general animation wrapper
- `React.addons.cloneWithProps` was added for cloning components and modifying their props
- Bug fix for adding back nodes during an exit transition for CSSTransitionGroup
- Bug fix for changing `transitionLeave` in CSSTransitionGroup
- Performance optimizations for CSSTransitionGroup
- On checkbox `<input>` elements, `checkedLink` is now supported for two-way binding
### JSX Compiler and react-tools Package
- Whitespace normalization has changed; now space between two tags on the same line will be preserved, while newlines between two tags will be removed
- The `react-tools` npm package no longer includes the React core libraries; use the `react` package instead.
- `displayName` is now added in more cases, improving error messages and names in the React Dev Tools
- Fixed an issue where an invalid token error was thrown after a JSX closing tag
- `JSXTransformer` now uses source maps automatically in modern browsers
- `JSXTransformer` error messages now include the filename and problematic line contents when a file fails to parse

title: React v0.9
layout: post
author: Ben Alpert
---
I'm excited to announce that today we're releasing React v0.9, which incorporates many bug fixes and several new features since the last release. This release contains almost four months of work, including over 800 commits from over 70 committers!
Thanks to everyone who tested the release candidate; we were able to find and fix an error in the event handling code, we upgraded envify to make running browserify on React faster, and we added support for five new attributes.
As always, the release is available for download from the CDN:
* **React**
Dev build with warnings: <http://fb.me/react-0.9.0.js>
Minified build for production: <http://fb.me/react-0.9.0.min.js>
* **React with Add-Ons**
Dev build with warnings: <http://fb.me/react-with-addons-0.9.0.js>
Minified build for production: <http://fb.me/react-with-addons-0.9.0.min.js>
* **In-Browser JSX Transformer**
<http://fb.me/JSXTransformer-0.9.0.js>
We've also published version `0.9.0` of the `react` and `react-tools` packages on npm and the `react` package on bower.
## Whats New?
This version includes better support for normalizing event properties across all supported browsers so that you need to worry even less about cross-browser differences. We've also made many improvements to error messages and have refactored the core to never rethrow errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly.
We've also added to the add-ons build [React.addons.TestUtils](/react/docs/test-utils.html), a set of new utilities to help you write unit tests for React components. You can now simulate events on your components, and several helpers are provided to help make assertions about the rendered DOM tree.
We've also made several other improvements and a few breaking changes; the full changelog is provided below.
## JSX Whitespace
In addition to the changes to React core listed below, we've made a small change to the way JSX interprets whitespace to make things more consistent. With this release, space between two components on the same line will be preserved, while a newline separating a text node from a tag will be eliminated in the output. Consider the code:
```html
<div>
Monkeys:
{listOfMonkeys} {submitButton}
</div>
```
In v0.8 and below, it was transformed to the following:
```javascript
React.DOM.div(null,
" Monkeys: ",
listOfMonkeys, submitButton
)
```
In v0.9, it will be transformed to this JS instead:
```javascript{2,3}
React.DOM.div(null,
"Monkeys:",
listOfMonkeys, " ", submitButton
)
```
We believe this new behavior is more helpful and elimates cases where unwanted whitespace was previously added.
In cases where you want to preserve the space adjacent to a newline, you can write `{'Monkeys: '}` or `Monkeys:{' '}` in your JSX source. We've included a script to do an automated codemod of your JSX source tree that preserves the old whitespace behavior by adding and removing spaces appropriately. You can [install jsx\_whitespace\_transformer from npm](https://github.com/facebook/react/blob/master/npm-jsx_whitespace_transformer/README.md) and run it over your source tree to modify files in place. The transformed JSX files will preserve your code's existing whitespace behavior.

title: "Community Round-up #17"
layout: post
author: Jonas Gebhardt
---
It's exciting to see the number of real-world React applications and components skyrocket over the past months! This community round-up features a few examples of inspiring React applications and components.
## React in the Real World
### Facebook Lookback video editor
Large parts of Facebook's web frontend are already powered by React. The recently released Facebook [Lookback video and its corresponding editor](https://www.facebook.com/lookback/edit/) are great examples of a complex, real-world React app.
### Russia's largest bank is now powered by React
Sberbank, Russia's largest bank, recently switched large parts of their site to use React, as detailed in [this post by Vyacheslav Slinko](https://groups.google.com/forum/#!topic/reactjs/Kj6WATX0atg).
### Relato
[Relato](http://bripkens.github.io/relato/) by [Ben Ripkens](https://github.com/bripkens) shows Open Source Statistics based on npm data. It features a filterable and sortable table built in React. Check it out &ndash; it's super fast!
### Makona Editor
John Lynch ([@johnrlynch](https://twitter.com/johnrlynch)) created Makona, a block-style document editor for the web. Blocks of different content types comprise documents, authored using plain markup. At the switch of a toggle, block contents are then rendered on the page. While not quite a WYSIWYG editor, Makona uses plain textareas for input. This makes it compatible with a wider range of platforms than traditional rich text editors.

title: "Community Round-up #18"

In this Round-up, we are taking a few closer looks at React's interplay with different frameworks and architectures.
## "Little framework BIG splash"
Let's start with yet another refreshing introduction to React: Craig Savolainen ([@maedhr](https://twitter.com/maedhr)) walks through some first steps, demonstrating [how to build a Google Maps component](http://infinitemonkeys.influitive.com/little-framework-big-splash) using React.
## Architecting your app with react
Brandon Konkle ([@bkonkle](https://twitter.com/bkonkle))
[Architecting your app with react](http://lincolnloop.com/blog/architecting-your-app-react-part-1/)
We're looking forward to part 2!
> React is not a full MVC framework, and this is actually one of its strengths. Many who adopt React choose to do so alongside their favorite MVC framework, like Backbone. React has no opinions about routing or syncing data, so you can easily use your favorite tools to handle those aspects of your frontend application. You'll often see React used to manage specific parts of an application's UI and not others. React really shines, however, when you fully embrace its strategies and make it the core of your application's interface.
>
> [Read the full article...](http://lincolnloop.com/blog/architecting-your-app-react-part-1/)
## React vs. async DOM manipulation
Eliseu Monar ([@eliseumds](https://twitter.com/eliseumds))'s post "[ReactJS vs async concurrent rendering](http://eliseu.tk/post/77843550010/vitalbox-pchr-reactjs-vs-async-concurrent-rendering)" is a great example of how React quite literally renders a whole array of common web development work(arounds) obsolete.
## React, Scala and the Play Framework
[Matthias Nehlsen](http://matthiasnehlsen.com/) wrote a detailed introductory piece on [React and the Play Framework](http://matthiasnehlsen.com/blog/2014/01/05/play-framework-and-facebooks-react-library/), including a helpful architectural diagram of a typical React app.
Nehlsen's React frontend is the second implementation of his chat application's frontend, following an AngularJS version. Both implementations are functionally equivalent and offer some perspective on differences between the two frameworks.
In [another article](http://matthiasnehlsen.com/blog/2014/01/24/scala-dot-js-and-reactjs/), he walks us through the process of using React with scala.js to implement app-wide undo functionality.
Also check out his [talk](http://m.ustream.tv/recorded/42780242) at Ping Conference 2014, in which he walks through a lot of the previously content in great detail.
## React and Backbone
The folks over at [Venmo](https://venmo.com/) are using React in conjunction with Backbone.
Thomas Boyt ([@thomasaboyt](https://twitter.com/thomasaboyt)) wrote [this detailed piece](http://www.thomasboyt.com/2013/12/17/using-reactjs-as-a-backbone-view.html) about why React and Backbone are "a fantastic pairing".
## React vs. Ember
Eric Berry ([@coderberry](https://twitter.com/coderberry)) developed Ember equivalents for some of the official React examples. Read his post for a side-by-side comparison of the respective implementations: ["Facebook React vs. Ember"](http://instructure.github.io/blog/2013/12/17/facebook-react-vs-ember/).
## React and plain old HTML
Daniel Lo Nigro ([@Daniel15](https://twitter.com/Daniel15)) created [React-Magic](https://github.com/reactjs/react-magic), which leverages React to ajaxify plain old html pages and even [allows CSS transitions between pageloads](http://stuff.dan.cx/facebook/react-hacks/magic/red.php).
> React-Magic intercepts all navigation (link clicks and form posts) and loads the requested page via an AJAX request. React is then used to "diff" the old HTML with the new HTML, and only update the parts of the DOM that have been changed.

> [Check out the project on GitHub...](https://github.com/reactjs/react-magic)
On a related note, [Reactize](https://turbo-react.herokuapp.com/) by Ross Allen ([@ssorallen](https://twitter.com/ssorallen)) is a similarly awesome project: A wrapper for Rails' [Turbolinks](https://github.com/rails/turbolinks/), which seems to have inspired John Lynch ([@johnrlynch](https://twitter.com/johnrlynch)) to then create [a server-rendered version using the JSX transformer in Rails middleware](http://www.rigelgroupllc.com/blog/2014/01/12/react-jsx-transformer-in-rails-middleware/).

Check out [François de Campredon](https://github.com/fdecampredon)'s implementation of [TodoMVC based on React and ES6's Object.observe](https://github.com/fdecampredon/react-observe-todomvc/).
## React and Angular
Ian Bicking ([@ianbicking](https://twitter.com/ianbicking)) of Mozilla Labs [explains why he "decided to go with React instead of Angular.js"](https://plus.google.com/+IanBicking/posts/Qj8R5SWAsfE).
### ng-React Update
[David Chang](https://github.com/davidchang) works through some performance improvements of his [ngReact](https://github.com/davidchang/ngReact) project. His post ["ng-React Update - React 0.9 and Angular Track By"](http://davidandsuzi.com/ngreact-update/) includes some helpful advice on boosting render performance for Angular components.
> Angular gives you a ton of functionality out of the box - a full MV* framework - and I am a big fan, but I'll admit that you need to know how to twist the right knobs to get performance.

Jonathan Krause ([@jonykrause](https://twitter.com/jonykrause)) offers his thoughts regarding [parallels between React and Web Components](http://jonykrau.se/posts/the-value-of-react), highlighting the value of React's ability to render pages on the server practically for free.
## Immutable React
[Peter Hausel](http://pk11.kinja.com/) shows how to build a Wikipedia auto-complete demo based on immutable data structures (similar to [mori](https://npmjs.org/package/mori)), really taking advantage of the framework's one-way reactive data binding:

[Ben Smith](http://10consulting.com/) built some great SVG-based charting components using a little less of D3 and a little more of React: [D3 and React - the future of charting components?](http://10consulting.com/2014/02/19/d3-plus-reactjs-for-charting/)
## Om and React
Josh Haberman ([@joshhaberman](https://twitter.com/JoshHaberman)) discusses performance differences between React, Om and traditional MVC frameworks in "[A closer look at OM vs React performance](http://blog.reverberate.org/2014/02/on-future-of-javascript-mvc-frameworks.html)".
Speaking of Om: [Omchaya](https://github.com/sgrove/omchaya) by Sean Grove ([@sgrove](https://twitter.com/sgrove)) is a neat Cljs/Om example project.

title: React v0.10 RC
layout: post
author: Paul OShannessy
---
[v0.9 has only been out for a month](http://facebook.github.io/react/blog/2014/02/20/react-v0.9.html), but were getting ready to push out v0.10 already. Unlike v0.9 which took a long time, we don't have a long list of changes to talk about.
The release candidate is available for download from the CDN:
* **React**
Dev build with warnings: <http://fb.me/react-0.10.0-rc1.js>
Minified build for production: <http://fb.me/react-0.10.0-rc1.min.js>
* **React with Add-Ons**
Dev build with warnings: <http://fb.me/react-with-addons-0.10.0-rc1.js>
Minified build for production: <http://fb.me/react-with-addons-0.10.0-rc1.min.js>
* **In-Browser JSX transformer**
<http://fb.me/JSXTransformer-0.10.0-rc1.js>
We've also published version `0.10.0-rc1` of the `react` and `react-tools` packages on npm and the `react` package on bower.
Please try these builds out and [file an issue on GitHub](https://github.com/facebook/react/issues/new) if you see anything awry.
## Clone On Mount
The main purpose of this release is to provide a smooth upgrade path as we evolve some of the implementation of core. In v0.9 we started warning in cases where you called methods on unmounted components. This is part of an effort to enforce the idea that the return value of a component (`React.DOM.div()`, `MyComponent()`) is in fact not a reference to the component instance React uses in the virtual DOM. The return value is instead a light-weight object that React knows how to use. Since the return value currently is a reference to the same object React uses internally, we need to make this transition in stages as many people have come to depend on this implementation detail.
In 0.10, were adding more warnings to catch a similar set of patterns. When a component is mounted we clone it and use that object for our internal representation. This allows us to capture calls you think youre making to a mounted component. Well forward them on to the right object, but also warn you that this is breaking. See “Access to the Mounted Instance” on [this page](http://fb.me/react-warning-descriptors). Most of the time you can solve your pattern by using refs.
Storing a reference to your top level component is a pattern touched upon on that page, but another examples that demonstrates what we see a lot of:
```js
// This is a common pattern. However instance here really refers to a
// "descriptor", not necessarily the mounted instance.
var instance = <MyComponent/>;
React.renderComponent(instance);
// ...
instance.setProps(...);
// The change here is very simple. The return value of renderComponent will be
// the mounted instance.
var instance = React.renderComponent(<MyComponent/>)
// ...
instance.setProps(...);
```
These warnings and method forwarding are only enabled in the development build. The production builds continue to work as they did in v0.9. We strongly encourage you to use the development builds to catch these warnings and fix the call sites.
The plan for v0.11 is that we will go fully to "descriptors". Method calls on the return value of `MyComponent()` will fail hard.
## Changelog
### React Core
#### New Features
* Made it possible to server render without React-related markup (`data-reactid`, `data-react-checksum`) - `React.renderComponentToStaticMarkup`
* Added support for more attributes:
* `srcSet` for `<img>` to images at different pixel ratios
* `textAnchor` for SVG
#### Bug Fixes
* Ensure all void elements dont insert a closing tag into the markup.
* Ensure `className={false}` behaves consistently
* Ensure `this.refs` is defined, even if no refs are specified.
### Addons
* `update` function to deal with immutable data.
### react-tools
* Added an option argument to `transform` function. The only option supported is `harmony`, which behaves the same as `jsx --harmony` on the command line. This uses the ES6 transforms from [jstransform](https://github.com/facebook/jstransform).

When React reconciles the keyed children, it will ensure that any child with `key` will be reordered (instead of clobbered) or destroyed (instead of reused).
You can also key children by passing an object. The object keys will be used as `key` for each value. However it is important to remember that JavaScript does not guarantee the ordering of properties will be preserved. In practice browsers will preserve property order **except** for properties that can be parsed as a 32-bit unsigned integers. Numeric properties will be ordered sequentially and before other properties. If this happens React will render components out of order. This can be avoided by adding a string prefix to the key:
```javascript
render: function() {
var items = {};
this.props.results.forEach(function(result) {
// If result.id can look like a number (consider short hashes), then
// object iteration order is not guaranteed. In this case, we add a prefix

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](/react/docs/component-specs.html) for more information.

## Prop Validation
As your app grows it's helpful to ensure that your components are used correctly. We do this by allowing you to specify `propTypes`. `React.PropTypes` exports a range of validators that can be used to make sure the data you receive is valid. When an invalid value is provided for a prop, a warning will be shown in the JavaScript console. Note that for performance reasons `propTypes` is only checked in development mode.

## Mixins
Components are the best way to reuse code in React, but sometimes very different components may share some common functionality. These are sometimes called [cross-cutting concerns](http://en.wikipedia.org/wiki/Cross-cutting_concern). React provides `mixins` to solve this problem.
One common use case is a component wanting to update itself on a time interval. It's easy to use `setInterval()`, but it's important to cancel your interval when you don't need it anymore to save memory. React provides [lifecycle methods](/react/docs/working-with-the-browser.html#component-lifecycle) that let you know when a component is about to be created or destroyed. Let's create a simple mixin that uses these methods to provide an easy `setInterval()` function that will automatically get cleaned up when your component is destroyed.

React provides a `ReactTransitionGroup` addon component as a low-level API for animation, and a `ReactCSSTransitionGroup` for easily implementing basic CSS animations and transitions.
`ReactTransitions` is an easy way to perform CSS transitions and animations when a React component enters or leaves the DOM. It's inspired by the excellent [ng-animate](http://www.nganimate.org/) library.

### Disabling Animations
## Disabling Animations
You can disable animating `enter` or `leave` animations if you want. For example, sometimes you may want an `enter` animation and no `leave` animation, but `ReactCSSTransitionGroup` waits for an animation to complete before removing your DOM node. You can add `transitionEnter={false}` or `transitionLeave={false}` props to `ReactCSSTransitionGroup` to disable these animations.

You can add `transitionEnter={false}` or `transitionLeave={false}` props to `ReactTransitionGroup` to disable these animations.
## Low-level API: `ReactTransitionGroup`
`ReactTransitionGroup` is the basis for animations. When children are declaratively added or removed from it (as in the example above) special lifecycle hooks are called on them.
### `componentWillEnter(callback)`
This is called at the same time as `componentDidMount()` for components added to an existing `TransitionGroup`. It will block other animations from occurring until `callback` is called. It will not be called on the initial render of a `TransitionGroup`.
### `componentDidEnter()`
This is called after the `callback` function that was passed to `componentWillEnter` is called.
### `componentWillLeave(callback)`
This is called when the child has been removed from the `ReactTransitionGroup`. Though the child has been removed, `ReactTransitionGroup` will keep it in the DOM until `callback` is called.
### `componentDidLeave()`
This is called when the `willLeave` `callback` is called (at the same time as `componentWillUnmount`).
### Rendering a Different Component
## Rendering a Different Component
By default `ReactTransitionGroup` renders as a `span`. You can change this behavior by providing a `component` prop. For example, here's how you would render a `<ul>`:
```javascript{1}
<ReactTransitionGroup component={React.DOM.ul}>
```javascript{3}
<ReactTransitionGroup
transitionName="example"
component={React.DOM.ul}>
...
</ReactTransitionGroup>

In rare situations a component may want to change the props of a component that it doesn't own (like changing the `className` of a component passed as `this.props.children`). Other times it may want to make multiple copies of a component passed to it. `cloneWithProps()` makes this possible.
#### `ReactComponent React.addons.cloneWithProps(ReactComponent component, object? extraProps)`
Do a shallow copy of `component` and merge any props provided by `extraProps`. Props are merged in the same manner as [`transferPropsTo()`](/react/docs/component-api.html#transferpropsto), so props like `className` will be merged intelligently.

We intentionally break with the spec here since the spec is inconsistent. **However**, `data-*` and `aria-*` attributes [conform to the specs](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes#data-*) and should be lower-cased only.

* 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](/react/docs/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.

Beside [DOM differences](/react/docs/dom-differences.html), React offers some attributes that simply don't exist in DOM.
- `key`: an optional, unique identifier. When your component shuffles around during `render` passes, it might be destroyed and recreated due to the diff algorithm. Assigning it a key that persists makes sure the component stays. See more [here](/react/docs/multiple-components.html#dynamic-children).
- `ref`: see [here](/react/docs/more-about-refs.html).
- `dangerouslySetInnerHTML`: takes an object with the key `__html` and a DOM string as value. This is mainly for cooperating with DOM string manipulation libraries. Refer to the last example on the front page.

title: Reconciliation

React key design decision is to make the API seem like it re-renders the whole app on every update. This makes writing applications a lot easier but is also an incredible challenge to make it tractable. This article explains how with powerful heuristics we managed to turn a O(n<sup>3</sup>) problem into a O(n) one.
## Motivation
Generating the minimum number of operations to transform one tree into another is a complex and well-studied problem. The [state of the art algorithms](http://grfia.dlsi.ua.es/ml/algorithms/references/editsurvey_bille.pdf) have a complexity in the order of O(n<sup>3</sup>) where n is the number of nodes in the tree.
This means that displaying 1000 nodes would require in the order of one billion comparisons. This is far too expensive for our use case. To put this number in perspective, CPUs nowadays execute roughly 3 billion instruction per second. So even with the most performant implementation, we wouldn't be able to compute that diff in less than a second.
Since an optimal algorithm is not tractable, we implement a non-optimal O(n) algorithm using heuristics based on two assumptions:
1. Two components of the same class will generate similar trees and two components of different classes will generate different trees.
2. It is possible to provide a unique key for elements that is stable across different renders.
In practice, these assumptions are ridiculously fast for almost all practical use cases.
## Pair-wise diff
In order to do a tree diff, we first need to be able to diff two nodes. There are three different cases being handled.
### Different Node Types
If the node type is different, React is going to treat them as two different sub-trees, throw away the first one and build/insert the second one.
```xml
renderA: <div />
renderB: <span />
=> [removeNode <div />], [insertNode <span />]
```
The same logic is used for custom components. If they are not of the same type, React is not going to even try at matching what they render. It is just going to remove the first one from the DOM and insert the second one.
```xml
renderA: <Header />
renderB: <Content />
=> [removeNode <Header />], [insertNode <Content />]
```
Having this high level knowledge is a very important aspect of why React diff algorithm is both fast and precise. It provides a good heuristic to quickly prune big parts of the tree and focus on parts likely to be similar.
It is very unlikely that a `<Header>` element is going generate a DOM that is going to look like what a `<Content>` would generate. Instead of spending time trying to match those two structures, React just re-builds the tree from scratch.
As a corollary, if there is a `<Header>` element at the same position in two consecutive renders, you would expect to see a very similar structure and it is worth exploring it.
### DOM Nodes
When comparing two DOM nodes, we look at the attributes of both and can decide which of them changed in linear time.
```xml
renderA: <div id="before" />
renderB: <div id="after" />
=> [replaceAttribute id "after"]
```
Instead of treating style as an opaque string, a key-value object is used instead. This lets us update only the properties that changed.
```xml
renderA: <div style={{'{{'}}color: 'red'}} />
renderB: <div style={{'{{'}}fontWeight: 'bold'}} />
=> [removeStyle color], [addStyle font-weight 'bold']
```
After the attributes have been updated, we recurse on all the children.
### Custom Components
We decided that the two custom components are the same. Since components are stateful, we cannot just use the new component and call it a day. React takes all the attributes from the new component and call `component[Will/Did]ReceiveProps()` on the previous one.
The previous component is now operational. Its `render()` method is called and the diff algorithm restarts with the new result and the previous result.
## List-wise diff
### Problematic Case
In order to do children reconciliation, React adopts a very naive approach. It goes over the list of children both at the same time and whenever there's a difference generates a mutation.
For example if you add an element at the end:
```xml
renderA: <div><span>first</span></div>
renderB: <div><span>first</span><span>second</span></div>
=> [insertNode <span>second</span>]
```
Inserting an element at the beginning is problematic. React is going to see that both nodes are spans and therefore run into a mutation mode.
```xml
renderA: <div><span>first</span></div>
renderB: <div><span>second</span><span>first</span></div>
=> [replaceAttribute textContent 'second'], [insertNode <span>first</span>]
```
There are many algorithms that attempt to find the minimum sets of operations to transform a list of elements. [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance) can find the minimum using single element insertion, deletion and substitution in O(n<sup>2</sup>). Even if we were to use Levenshtein, this doesn't find when a node has moved into another position and algorithms to do that have much worse complexity.
### Keys
In order to solve this seemingly intractable issue, an optional attribute has been introduced. You can provide for each child a key that is going to be used to do the matching. If you specify a key, React is now able to find insertion, deletion, substitution and moves in O(n) using a hash table.
```xml
renderA: <div><span key="first">first</span></div>
renderB: <div><span key="second">second</span><span key="first">first</span></div>
=> [insertNode <span>second</span>]
```
In practice, finding a key is not really hard. Most of the time, the element you are going to display already have a unique id. When it is not the case, you can hash some parts of the content to generate an id. Remember that the id only has to be unique among its sibling, not globally unique.
## Trade-offs
It is important to remember that the reconciliation algorithm is an implementation detail. React could re-render the whole app on every action, the end-result would be the same. We are regularly refining the heuristics in order to make common use cases faster.
In the current implementation, you can express the fact that a sub-tree has been moved between siblings, but you cannot tell that it has moved somewhere else. The algorithm will re-render that full sub-tree.
Because we rely on two heuristics, if the assumptions behind them are not met, performance will suffer.
1. The algorithm will not try to match sub-trees of different components classes. If you see yourself alternating between two components classes with very similar output, you may want to make it the same class. In practice, we haven't found this to be an issue.
2. If you don't provide stable keys (by using Math.random() for example), all the sub-trees are going to be re-rendered every single time. By giving the users the choice to chose the key, they have the ability to shoot themselves in the foot.

This was originally a [blog post](/react/blog/2013/11/05/thinking-in-react.html) from the [official React blog](/react/blog).
React is, in my opinion, the premier way to build big, fast Web apps with JavaScript. It's scaled very well for us at Facebook and Instagram.
One of the many great parts of React is how it makes you think about apps as you build them. In this post I'll walk you through the thought process of building a searchable product data table using React.
## Start with a mock
Imagine that we already have a JSON API and a mock from our designer. Our designer apparently isn't very good because the mock looks like this:
![Mockup](/react/img/blog/thinking-in-react-mock.png)
Our JSON API returns some data that looks like this:
```
[
{category: "Sporting Goods", price: "$49.99", stocked: true, name: "Football"},
{category: "Sporting Goods", price: "$9.99", stocked: true, name: "Baseball"},
{category: "Sporting Goods", price: "$29.99", stocked: false, name: "Basketball"},
{category: "Electronics", price: "$99.99", stocked: true, name: "iPod Touch"},
{category: "Electronics", price: "$399.99", stocked: false, name: "iPhone 5"},
{category: "Electronics", price: "$199.99", stocked: true, name: "Nexus 7"}
];
```
## Step 1: break the UI into a component hierarchy
The first thing you'll want to do is to draw boxes around every component (and subcomponent) in the mock and give them all names. If you're working with a designer they may have already done this, so go talk to them! Their Photoshop layer names may end up being the names of your React components!
But how do you know what should be its own component? Just use the same techniques for deciding if you should create a new function or object. One such technique is the [single responsibility principle](http://en.wikipedia.org/wiki/Single_responsibility_principle), that is, a component should ideally only do one thing. If it ends up growing it should be decomposed into smaller subcomponents.
Since you're often displaying a JSON data model to a user, you'll find that if your model was built correctly your UI (and therefore your component structure) will map nicely onto it. That's because user interfaces and data models tend to adhere to the same *information architecture* which means the work of separating your UI into components is often trivial. Just break it up into components that represent exactly one piece of your data model.
![Component diagram](/react/img/blog/thinking-in-react-components.png)
You'll see here that we have five components in our simple app. I've italicized the data each component represents.
1. **`FilterableProductTable` (orange):** contains the entirety of the example
2. **`SearchBar` (blue):** receives all *user input*
3. **`ProductTable` (green):** displays and filters the *data collection* based on *user input*
4. **`ProductCategoryRow` (turquoise):** displays a heading for each *category*
5. **`ProductRow` (red):** displays a row for each *product*
If you look at `ProductTable` you'll see that the table header (containing the "Name" and "Price" labels) isn't its own component. This is a matter of preference and there's an argument to be made either way. For this example I left it as part of `ProductTable` because it is part of rendering the *data collection* which is `ProductTable`'s responsibility. However if this header grows to be complex (i.e. if we were to add affordances for sorting) it would certainly make sense to make this its own `ProductTableHeader` component.
Now that we've identified the components in our mock, let's arrange them into a hierarchy. This is easy. Components that appear within another component in the mock should appear as a child in the hierarchy:
* `FilterableProductTable`
* `SearchBar`
* `ProductTable`
* `ProductCategoryRow`
* `ProductRow`
## Step 2: Build a static version in React
<iframe width="100%" height="300" src="http://jsfiddle.net/6wQMG/embedded/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
Now that you have your component hierarchy it's time to start implementing your app. The easiest way is to build a version that takes your data model and renders the UI but has no interactivity. It's easiest to decouple these processes because building a static version requires a lot of typing and no thinking, and adding interactivity requires a lot of thinking and not a lot of typing. We'll see why.
To build a static version of your app that renders your data model you'll want to build components that reuse other components and pass data using *props*. *props* are a way of passing data from parent to child. If you're familiar with the concept of *state*, **don't use state at all** to build this static version. State is reserved only for interactivity, that is, data that changes over time. Since this is a static version of the app you don't need it.
You can build top-down or bottom-up. That is, you can either start with building the components higher up in the hierarchy (i.e. starting with `FilterableProductTable`) or with the ones lower in it (`ProductRow`). In simpler examples it's usually easier to go top-down and on larger projects it's easier to go bottom-up and write tests as you build.
At the end of this step you'll have a library of reusable components that render your data model. The components will only have `render()` methods since this is a static version of your app. The component at the top of the hierarchy (`FilterableProductTable`) will take your data model as a prop. If you make a change to your underlying data model and call `renderComponent()` again the UI will be updated. It's easy to see how your UI is updated and where to make changes since there's nothing complicated going on since React's **one-way data flow** (also called *one-way binding*) keeps everything modular, easy to reason about, and fast.
Simply refer to the [React docs](http://facebook.github.io/react/docs/) if you need help executing this step.
### A brief interlude: props vs state
There are two types of "model" data in React: props and state. It's important to understand the distinction between the two; skim [the official React docs](http://facebook.github.io/react/docs/interactivity-and-dynamic-uis.html) if you aren't sure what the difference is.
## Step 3: Identify the minimal (but complete) representation of UI state
To make your UI interactive you need to be able to trigger changes to your underlying data model. React makes this easy with **state**.
To build your app correctly you first need to think of the minimal set of mutable state that your app needs. The key here is DRY: *Don't Repeat Yourself*. Figure out what the absolute minimal representation of the state of your application needs to be and compute everything else you need on-demand. For example, if you're building a TODO list, just keep an array of the TODO items around; don't keep a separate state variable for the count. Instead, when you want to render the TODO count simply take the length of the TODO items array.
Think of all of the pieces of data in our example application. We have:
* The original list of products
* The search text the user has entered
* The value of the checkbox
* The filtered list of products
Let's go through each one and figure out which one is state. Simply ask three questions about each piece of data:
1. Is it passed in from a parent via props? If so, it probably isn't state.
2. Does it change over time? If not, it probably isn't state.
3. Can you compute it based on any other state or props in your component? If so, it's not state.
The original list of products is passed in as props, so that's not state. The search text and the checkbox seem to be state since they change over time and can't be computed from anything. And finally, the filtered list of products isn't state because it can be computed by combining the original list of products with the search text and value of the checkbox.
So finally, our state is:
* The search text the user has entered
* The value of the checkbox
## Step 4: Identify where your state should live
<iframe width="100%" height="300" src="http://jsfiddle.net/QvHnx/embedded/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
OK, so we've identified what the minimal set of app state is. Next we need to identify which component mutates, or *owns*, this state.
Remember: React is all about one-way data flow down the component hierarchy. It may not be immediately clear which component should own what state. **This is often the most challenging part for newcomers to understand,** so follow these steps to figure it out:
For each piece of state in your application:
* Identify every component that renders something based on that state.
* Find a common owner component (a single component above all the components that need the state in the hierarchy).
* Either the common owner or another component higher up in the hierarchy should own the state.
* If you can't find a component where it makes sense to own the state, create a new component simply for holding the state and add it somewhere in the hierarchy above the common owner component.
Let's run through this strategy for our application:
* `ProductTable` needs to filter the product list based on state and `SearchBar` needs to display the search text and checked state.
* The common owner component is `FilterableProductTable`.
* It conceptually makes sense for the filter text and checked value to live in `FilterableProductTable`
Cool, so we've decided that our state lives in `FilterableProductTable`. First, add a `getInitialState()` method to `FilterableProductTable` that returns `{filterText: '', inStockOnly: false}` to reflect the initial state of your application. Then pass `filterText` and `inStockOnly` to `ProductTable` and `SearchBar` as a prop. Finally, use these props to filter the rows in `ProductTable` and set the values of the form fields in `SearchBar`.
You can start seeing how your application will behave: set `filterText` to `"ball"` and refresh your app. You'll see the data table is updated correctly.
## Step 5: Add inverse data flow
<iframe width="100%" height="300" src="http://jsfiddle.net/3Vs3Q/embedded/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
So far we've built an app that renders correctly as a function of props and state flowing down the hierarchy. Now it's time to support data flowing the other way: the form components deep in the hierarchy need to update the state in `FilterableProductTable`.
React makes this data flow explicit to make it easy to understand how your program works, but it does require a little more typing than traditional two-way data binding. React provides an add-on called `ReactLink` to make this pattern as convenient as two-way binding, but for the purpose of this post we'll keep everything explicit.
If you try to type or check the box in the current version of the example you'll see that React ignores your input. This is intentional, as we've set the `value` prop of the `input` to always be equal to the `state` passed in from `FilterableProductTable`.
Let's think about what we want to happen. We want to make sure that whenever the user changes the form we update the state to reflect the user input. Since components should only update their own state, `FilterableProductTable` will pass a callback to `SearchBar` that will fire whenever the state should be updated. We can use the `onChange` event on the inputs to be notified of it. And the callback passed by `FilterableProductTable` will call `setState()` and the app will be updated.
Though this sounds like a lot it's really just a few lines of code. And it's really explicit how your data is flowing throughout the app.
## And that's it
Hopefully this gives you an idea of how to think about building components and applications with React. While it may be a little more typing than you're used to, remember that code is read far more than it's written, and it's extremely easy to read this modular, explicit code. As you start to build large libraries of components you'll appreciate this explicitness and modularity, and with code reuse your lines of code will start to shrink :)

For more info about the `jsx` binary, see the [Getting Started](/react/docs/getting-started.html#offline-transform) guide.
If you're using an npm-compatible packaging system like browserify or webpack, you can use the `react` package. After installing it using `npm install react` or adding `react` to `package.json`, you can use React:
```js
var React = require('react');
React.renderComponent(...);
```
If you'd like to use any [add-ons](/react/docs/addons.html), use `var React = require('react/addons');` instead.
All scripts are also available via [CDNJS](http://cdnjs.com/#react).
## Bower
```sh
$ bower install --save react
```
## NPM
```sh
$ npm install -g react-tools
```
