v0.8.0

These should be included so that anybody can build and update the docs
with as little confusion as possible.

I've left the directory in .gitignore so additions need to be
intentional as part of a release.

+## 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)
+
+### React
+
+* Fixed bug with `<input type="range">` and selection events.
+* Fixed bug with selection and focus.
+* Made it possible to unmount components from the document root.
+* Fixed bug for `disabled` attribute handling on non-`<input>` elements.
+
+### React with Addons
+
+* Fixed bug with transition and animation event detection.
+
+
+## 0.5.0 (October 16, 2013)
+
+### React
+
+* Memory usage improvements - reduced allocations in core which will help with GC pauses
+* Performance improvements - in addition to speeding things up, we made some tweaks to stay out of slow path code in V8 and Nitro.
+* Standardized prop -> DOM attribute process. This previously resulting in additional type checking and overhead as well as confusing cases for users. Now we will always convert your value to a string before inserting it into the DOM.
+* Support for Selection events.
+* Support for [Composition events](https://developer.mozilla.org/en-US/docs/Web/API/CompositionEvent).
+* Support for additional DOM properties (`charSet`, `content`, `form`, `httpEquiv`, `rowSpan`, `autoCapitalize`).
+* Support for additional SVG properties (`rx`, `ry`).
+* Support for using `getInitialState` and `getDefaultProps` in mixins.
+* Support mounting into iframes.
+* Bug fixes for controlled form components.
+* Bug fixes for SVG element creation.
+* Added `React.version`.
+* Added `React.isValidClass` - Used to determine if a value is a valid component constructor.
+* Removed `React.autoBind` - This was deprecated in v0.4 and now properly removed.
+* Renamed  `React.unmountAndReleaseReactRootNode` to `React.unmountComponentAtNode`.
+* Began laying down work for refined performance analysis.
+* Better support for server-side rendering - [react-page](https://github.com/facebook/react-page) has helped improve the stability for server-side rendering.
+* Made it possible to use React in environments enforcing a strict [Content Security Policy](https://developer.mozilla.org/en-US/docs/Security/CSP/Introducing_Content_Security_Policy). This also makes it possible to use React to build Chrome extensions.
+
+### React with Addons (New!)
+
+* Introduced a separate build with several "addons" which we think can help improve the React experience. We plan to deprecate this in the long-term, instead shipping each as standalone pieces. [Read more in the docs](http://facebook.github.io/react/docs/addons.html).
+
+### JSX
+
+* No longer transform `class` to `className` as part of the transform! This is a breaking change - if you were using `class`, you *must* change this to `className` or your components will be visually broken.
+* Added warnings to the in-browser transformer to make it clear it is not intended for production use.
+* Improved compatibility for Windows
+* Improved support for maintaining line numbers when transforming.

 React is a JavaScript library for building user interfaces.
 
-* **Declarative:** React uses a declarative paradigm that makes it easier to reason about your application.
-* **Efficient:** React computes the minimal set of changes necessary to keep your DOM up-to-date.
-* **Flexible:** React works with the libraries and frameworks that you already know.
+* **Just the UI:** Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
+* **Virtual DOM:** React uses a *virtual DOM* diff implementation for ultra-high performance. It can also render on the server using Node.js — no heavy browser DOM required.
+* **Data flow:** React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.

+layout: post
+author: Paul O'Shannessy
+---
+
+This release is the result of several months of hard work from members of the team and the community. While there are no groundbreaking changes in core, we've worked hard to improve performance and memory usage. We've also worked hard to make sure we are being consistent in our usage of DOM properties.
+
+The biggest change you'll notice as a developer is that we no longer support `class` in JSX as a way to provide CSS classes. Since this prop was being converted to `className` at the transform step, it caused some confusion when trying to access it in composite components. As a result we decided to make our DOM properties mirror their counterparts in the JS DOM API. There are [a few exceptions](https://github.com/facebook/react/blob/master/src/dom/DefaultDOMPropertyConfig.js#L156) where we deviate slightly in an attempt to be consistent internally.
+
+The other major change in v0.5 is that we've added an additional build - `react-with-addons` - which adds support for some extras that we've been working on including animations and two-way binding. [Read more about these addons in the docs](/react/docs/addons.html).
+
+## Thanks to Our Community
+
+We added *22 new people* to the list of authors since we launched React v0.4.1 nearly 3 months ago. With a total of 48 names in our `AUTHORS` file, that means we've nearly doubled the number of contributors in that time period. We've seen the number of people contributing to discussion on IRC, mailing lists, Stack Overflow, and GitHub continue rising. We've also had people tell us about talks they've given in their local community about React.
+
+It's been awesome to see the things that people are building with React, and we can't wait to see what you come up with next!
+
+
+## Changelog
+
+### React
+
+* Memory usage improvements - reduced allocations in core which will help with GC pauses
+* Performance improvements - in addition to speeding things up, we made some tweaks to stay out of slow path code in V8 and Nitro.
+* Standardized prop -> DOM attribute process. This previously resulting in additional type checking and overhead as well as confusing cases for users. Now we will always convert your value to a string before inserting it into the DOM.
+* Support for Selection events.
+* Support for [Composition events](https://developer.mozilla.org/en-US/docs/Web/API/CompositionEvent).
+* Support for additional DOM properties (`charSet`, `content`, `form`, `httpEquiv`, `rowSpan`, `autoCapitalize`).
+* Support for additional SVG properties (`rx`, `ry`).
+* Support for using `getInitialState` and `getDefaultProps` in mixins.
+* Support mounting into iframes.
+* Bug fixes for controlled form components.
+* Bug fixes for SVG element creation.
+* Added `React.version`.
+* Added `React.isValidClass` - Used to determine if a value is a valid component constructor.
+* Removed `React.autoBind` - This was deprecated in v0.4 and now properly removed.
+* Renamed  `React.unmountAndReleaseReactRootNode` to `React.unmountComponentAtNode`.
+* Began laying down work for refined performance analysis.
+* Better support for server-side rendering - [react-page](https://github.com/facebook/react-page) has helped improve the stability for server-side rendering.
+* Made it possible to use React in environments enforcing a strict [Content Security Policy](https://developer.mozilla.org/en-US/docs/Security/CSP/Introducing_Content_Security_Policy). This also makes it possible to use React to build Chrome extensions.
+
+### React with Addons (New!)
+
+* Introduced a separate build with several "addons" which we think can help improve the React experience. We plan to deprecate this in the long-term, instead shipping each as standalone pieces. [Read more in the docs](/react/docs/addons.html).
+
+### JSX
+
+* No longer transform `class` to `className` as part of the transform! This is a breaking change - if you were using `class`, you *must* change this to `className` or your components will be visually broken.
+* Added warnings to the in-browser transformer to make it clear it is not intended for production use.
+* Improved compatibility for Windows
+* Improved support for maintaining line numbers when transforming.

+title: "Thinking in React"
+layout: post
+author: Pete Hunt
+---
+
+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 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 :)

+
+This is the 10th round-up already and React has come quite far since it was open sourced. Almost all new web projects at Khan Academy, Facebook, and Instagram are being developed using React. React has been deployed in a variety of contexts: a Chrome extension, a Windows 8 application, mobile websites, and desktop websites supporting Internet Explorer 8! Language-wise, React is not only being used within JavaScript but also CoffeeScript and ClojureScript.
+
+The best part is that no drastic changes have been required to support all those use cases. Most of the efforts were targeted at polishing edge cases, performance improvements, and documentation.
+
+## Khan Academy - Officially moving to React
+
+[Joel Burget](http://joelburget.com/) announced at Hack Reactor that new front-end code at Khan Academy should be written in React!
+
+> How did we get the rest of the team to adopt React? Using interns as an attack vector! Most full-time devs had already been working on their existing projects for a while and weren't looking to try something new at the time, but our class of summer interns was just arriving. For whatever reason, a lot of them decided to try React for their projects. Then mentors became exposed through code reviews or otherwise touching the new code. In this way React knowledge diffused to almost the whole team over the summer.
+>
+> Since the first React checkin on June 5, we've somehow managed to accumulate 23500 lines of jsx (React-flavored js) code. Which is terrifying in a way - that's a lot of code - but also really exciting that it was picked up so quickly.
+>
+> We held three meetings about how we should proceed with React. At the first two we decided to continue experimenting with React and deferred a final decision on whether to adopt it. At the third we adopted the policy that new code should be written in React.
+>
+> I'm excited that we were able to start nudging code quality forward. However, we still have a lot of work to do! One of the selling points of this transition is adopting a uniform frontend style. We're trying to upgrade all the code from (really old) pure jQuery and (regular old) Backbone views / Handlebars to shiny React. At the moment all we've done is introduce more fragmentation. We won't be gratuitously updating working code (if it ain't broke, don't fix it), but are seeking out parts of the codebase where we can shoot two birds with one stone by rewriting in React while fixing bugs or adding functionality.

+
+Webkit has a [TodoMVC Benchmark](https://github.com/WebKit/webkit/tree/master/PerformanceTests/DoYouEvenBench) that compares different frameworks. They recently included React and here are the results (average of 10 runs in Chrome 30):
+
+- **AngularJS:** 4043ms
+- **AngularJSPerf:** 3227ms
+- **BackboneJS:** 1874ms
+- **EmberJS:** 6822ms
+- **jQuery:** 14628ms
+- **React:** 2864ms
+- **VanillaJS:** 5567ms
+
+[Try it yourself!](http://www.petehunt.net/react/tastejs/benchmark.html)
+
+Please don't take those numbers too seriously, they only reflect one very specific use case and are testing code that wasn't written with performance in mind.
+
+Even though React scores as one of the fastest frameworks in the benchmark, the React code is simple and idiomatic. The only performance tweak used is the following function:
+
+```javascript
+/**
+ * This is a completely optional performance enhancement that you can implement
+ * on any React component. If you were to delete this method the app would still
+ * work correctly (and still be very performant!), we just use it as an example
+ * of how little code it takes to get an order of magnitude performance improvement.
+ */
+shouldComponentUpdate: function (nextProps, nextState) {
+  return (
+    nextProps.todo.id !== this.props.todo.id ||
+    nextProps.todo !== this.props.todo ||
+    nextProps.editing !== this.props.editing ||
+    nextState.editText !== this.state.editText
+  );
+},
+```
+
+By default, React "re-renders" all the components when anything changes. This is usually fast enough that you don't need to care. However, you can provide a function that can tell whether there will be any change based on the previous and next states and props. If it is faster than re-rendering the component, then you get a performance improvement.
+
+The fact that you can control when components are rendered is a very important characteristic of React as it gives you control over its performance. We are going to talk more about performance in the future, stay tuned.

+## React vs FruitMachine
+
+[Andrew Betts](http://trib.tv/), director of the [Financial Times Labs](http://labs.ft.com/), posted an article comparing [FruitMachine](https://github.com/ftlabs/fruitmachine) and React.
+
+> Eerily similar, no? Maybe Facebook was inspired by Fruit Machine (after all, we got there first), but more likely, it just shows that this is a pretty decent way to solve the problem, and great minds think alike. We're graduating to a third phase in the evolution of web best practice - from intermingling of markup, style and behaviour, through a phase in which those concerns became ever more separated and encapsulated, and finally to a model where we can do that separation at a component level. Developments like Web Components show the direction the web community is moving, and frameworks like React and Fruit Machine are in fact not a lot more than polyfills for that promised behaviour to come.
+>

+Even though we weren't inspired by FruitMachine (React has been used in production since before FruitMachine was open sourced), it's great to see similar technologies emerging and becoming popular.

+## Intro to the React Framework
+
+[Pavan Podila](http://blog.pixelingene.com/) wrote an in-depth introduction to React on TutsPlus. This is definitively worth reading.
+
+> Within a component-tree, data should always flow down. A parent-component should set the props of a child-component to pass any data from the parent to the child. This is termed as the Owner-Owned pair. On the other hand user-events (mouse, keyboard, touches) will always bubble up from the child all the way to the root component, unless handled in between.

+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.

-## CSS Animation and Transitions
+- `ReactTransitions`, for dealing with animations and transitions that are usually not simple to implement, such as before a component's removal.
+- `ReactLink`, to simplify the coordination between user's form input data and and the component's state.
+- `classSet`, for manipulating the DOM `class` string a bit more cleanly.
 
-`ReactTransitions` is an easy way to perform CSS transitions and animations when a React component enters or leaves the DOM. `ReactTransitions` is inspired by the excellent [ng-animate](http://www.nganimate.org/) library.
-
-### Getting Started
-
-`ReactTransitionGroup` is the interface to `ReactTransitions`. This is a simple element that wraps all of the components you are interested in animating. Here's an example where we fade list items in and out.
-
-```javascript{22-24}
-/** @jsx React.DOM */
-
-var ReactTransitionGroup = React.addons.TransitionGroup;
-
-var TodoList = React.createClass({
-  getInitialState: function() {
-    return {items: ['hello', 'world', 'click', 'me']};
-  },
-  handleAdd: function() {
-    var newItems =
-      this.state.items.concat([prompt('Enter some text')]);
-    this.setState({items: newItems});
-  },
-  handleRemove: function(i) {
-    var newItems = this.state.items;
-    newItems.splice(i, 0)
-    this.setState({items: newItems});
-  },
-  render: function() {
-    var items = this.state.items.map(function(item, i) {
-      return (
-        <div key={i} onClick={this.handleRemove.bind(this, i)}>
-          {item}}
-        </div>
-      );
-    }.bind(this));
-    return (
-      <div>
-        <div><button onClick={this.handleAdd} /></div>
-        <ReactTransitionGroup transitionName="example">
-          {items}
-        </ReactTransitionGroup>
-      </div>
-    );
-  }
-});
-```
-
-In this component, when a new item is added `ReactTransitionGroup` it will get the `example-enter` CSS class and the `example-enter-active` CSS class added in the next tick. This is a convention based on the `transitionName` prop.
-
-You can use these classes to trigger a CSS animation or transition. For example, try adding this CSS and adding a new list item:
-
-```css
-.example-enter {
-  opacity: 0.01;
-  transition: opacity .5s ease-in;
-}
-
-.example-enter.example-enter-active {
-  opacity: 0.99;
-}
-```
-
-You'll notice that when you try to remove an item `ReactTransitionGroup` keeps it in the DOM. If you're using an unminified build of React you'll see a warning that React was expecting an animation or transition to occur. That's because `ReactTransitionGroup` keeps your DOM elements on the page until the animation completes. Try adding this CSS:
-
-```css
-.example-leave {
-  opacity: 0.99;
-  transition: opacity .5s ease-in;
-}
-
-.example-leave.example-leave-active {
-  opacity: 0.01;
-}
-```
-
-### 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 `ReactTransitionGroup` waits for an animation to complete before removing your DOM node. You can add `transitionEnter={false}` or `transitionLeave={false}` props to `ReactTransitionGroup` to disable these animations.
-
-### 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{3}
-<ReactTransitionGroup
-  transitionName="example"
-  component={React.DOM.ul}>
-  ...
-</ReactTransitionGroup>
-```
-
-`component` does not need to be a DOM component. It can be any component you want; even one you've written yourself!
-
-## ReactLink
-
-`ReactLink` is an easy way to express two-way binding with React.
-
-In React, data flows one way: from owner to child. This is because data only flows one direction in [the Von Neumann model of computing](http://en.wikipedia.org/wiki/Von_Neumann_architecture). You can think of it as "one-way data binding."
-
-However, there are lots of applications that require you to read some data and flow it back into your program. For example, when developing forms, you'll often want to update some React `state` when you receive user input. Or perhaps you want to perform layout in JavaScript and react to changes in some DOM element size.
-
-In React, you would implement this by listening to a "change" event, read from your data source (usually the DOM) and call `setState()` on one of your components. "Closing the data flow loop" explicitly leads to more understandable and easier-to-maintain programs. See [our forms documentation](./forms.html) for more information.
-
-Two-way binding -- implicitly enforcing that some value in the DOM is always consistent with some React `state` -- is concise and supports a wide variety of applications. We've provided `ReactLink`: syntactic sugar for setting up the common data flow loop pattern described above, or "linking" some data source to React `state`.
-
-> Note:
->
-> ReactLink is just a thin wrapper and convention around the `onChange`/`setState()` pattern. It doesn't fundamentally change how data flows in your React application.
-
-### ReactLink: Before and After
-
-Here's a simple form example without using `ReactLink`:
-
-```javascript
-/** @jsx React.DOM */
-
-var NoLink = React.createClass({
-  getInitialState: function() {
-    return {value: 'Hello!'};
-  },
-  handleChange: function(event) {
-    this.setState({value: event.target.value});
-  },
-  render: function() {
-    var value = this.state.value;
-    return <input type="text" value={value} onChange={this.handleChange} />;
-  }
-});
-```
-
-This works really well and it's very clear how data is flowing, however with a lot of form fields it could get a bit verbose. Let's use `ReactLink` to save us some typing:
-
-```javascript{4,9}
-/** @jsx React.DOM */
-
-var WithLink = React.createClass({
-  mixins: [React.addons.LinkedStateMixin],
-  getInitialState: function() {
-    return {value: 'Hello!'};
-  },
-  render: function() {
-    return <input type="text" valueLink={this.linkState('value')} />;
-  }
-});
-```
-
-`LinkedStateMixin` adds a method ot your React component called `linkState()`. `linkState()` returns a `ReactLink` object which contains the current value of the React state and a callback to change it.
-
-`ReactLink` objects can be passed up and down the tree as props, so it's easy (and explicit) to set up two-way binding between a component deep in the hierarchy and state that lives higher in the hierarchy.
-
-### Under the Hood
-
-There are two sides to `ReactLink`: the place where you create the `ReactLink` instance and the place where you use it. To prove how simple `ReactLink` is, let's rewrite each side separately to be more explicit.
-
-#### ReactLink Without LinkedStateMixin
-
-```javascript{7-9,11-14}
-/** @jsx React.DOM */
-
-var WithoutMixin = React.createClass({
-  getInitialState: function() {
-    return {value: 'Hello!'};
-  },
-  handleChange: function(newValue) {
-    this.setState({value: newValue});
-  },
-  render: function() {
-    var valueLink = {
-      value: this.state.value,
-      requestChange: this.handleChange
-    };
-    return <input type="text" valueLink={valueLink} />;
-  }
-});
-```
-
-As you can see, `ReactLink` objects are very simple objects that just have a `value` and `requestChange` prop. And `LinkedStateMixin` is similarly simple: it just populates those fields with a value from `this.state` and a callback that calls `this.setState()`.
-
-#### ReactLink Without valueLink
-
-```javascript
-/** @jsx React.DOM */
-
-var WithoutLink = React.createClass({
-  mixins: [React.addons.LinkedStateMixin],
-  getInitialState: function() {
-    return {value: 'Hello!'};
-  },
-  render: function() {
-    var valueLink = this.linkState('value');
-    var handleChange = function(e) {
-      valueLink.requestChange(e.target.value);
-    };

-The `valueLink` prop is also quite simple. It simply handles the `onChange` event and calls `this.props.valueLink.requestChange()` and also uses `this.props.valueLink.value` instead of `this.props.value`. That's it!

+
+`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.
+
+## Getting Started
+
+`ReactTransitionGroup` is the interface to `ReactTransitions`. This is a simple element that wraps all of the components you are interested in animating. Here's an example where we fade list items in and out.
+
+```javascript{22-24}
+/** @jsx React.DOM */
+
+var ReactTransitionGroup = React.addons.TransitionGroup;
+
+var TodoList = React.createClass({
+  getInitialState: function() {
+    return {items: ['hello', 'world', 'click', 'me']};
+  },
+  handleAdd: function() {
+    var newItems =
+      this.state.items.concat([prompt('Enter some text')]);
+    this.setState({items: newItems});
+  },
+  handleRemove: function(i) {
+    var newItems = this.state.items;
+    newItems.splice(i, 1)
+    this.setState({items: newItems});
+  },
+  render: function() {
+    var items = this.state.items.map(function(item, i) {
+      return (
+        <div key={i} onClick={this.handleRemove.bind(this, i)}>
+          {item}
+        </div>
+      );
+    }.bind(this));
+    return (
+      <div>
+        <div><button onClick={this.handleAdd} /></div>
+        <ReactTransitionGroup transitionName="example">
+          {items}
+        </ReactTransitionGroup>
+      </div>
+    );
+  }
+});
+```
+
+In this component, when a new item is added to `ReactTransitionGroup` it will get the `example-enter` CSS class and the `example-enter-active` CSS class added in the next tick. This is a convention based on the `transitionName` prop.
+
+You can use these classes to trigger a CSS animation or transition. For example, try adding this CSS and adding a new list item:
+
+```css
+.example-enter {
+  opacity: 0.01;
+  transition: opacity .5s ease-in;
+}
+
+.example-enter.example-enter-active {
+  opacity: 1;
+}
+```
+
+You'll notice that when you try to remove an item `ReactTransitionGroup` keeps it in the DOM. If you're using an unminified build of React with add-ons you'll see a warning that React was expecting an animation or transition to occur. That's because `ReactTransitionGroup` keeps your DOM elements on the page until the animation completes. Try adding this CSS:
+
+```css
+.example-leave {
+  opacity: 1;
+  transition: opacity .5s ease-in;
+}
+
+.example-leave.example-leave-active {
+  opacity: 0.01;
+}
+```
+
+## 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 `ReactTransitionGroup` waits for an animation to complete before removing your DOM node. You can add `transitionEnter={false}` or `transitionLeave={false}` props to `ReactTransitionGroup` to disable these animations.
+
+## 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{3}
+<ReactTransitionGroup
+  transitionName="example"
+  component={React.DOM.ul}>
+  ...
+</ReactTransitionGroup>
+```
+
+Every DOM component is under `React.DOM`. However, `component` does not need to be a DOM component. It can be any React component you want; even ones you've written yourself!

+
+`ReactLink` is an easy way to express two-way binding with React. 
+
+> Note:
+>
+> If you're new to the framework, note that `ReactLink` is not needed for most applications and should be used cautiously.
+
+In React, data flows one way: from owner to child. This is because data only flows one direction in [the Von Neumann model of computing](http://en.wikipedia.org/wiki/Von_Neumann_architecture). You can think of it as "one-way data binding."
+
+However, there are lots of applications that require you to read some data and flow it back into your program. For example, when developing forms, you'll often want to update some React `state` when you receive user input. Or perhaps you want to perform layout in JavaScript and react to changes in some DOM element size.
+
+In React, you would implement this by listening to a "change" event, read from your data source (usually the DOM) and call `setState()` on one of your components. "Closing the data flow loop" explicitly leads to more understandable and easier-to-maintain programs. See [our forms documentation](./forms.html) for more information.
+
+Two-way binding -- implicitly enforcing that some value in the DOM is always consistent with some React `state` -- is concise and supports a wide variety of applications. We've provided `ReactLink`: syntactic sugar for setting up the common data flow loop pattern described above, or "linking" some data source to React `state`.
+
+> Note:
+>
+> ReactLink is just a thin wrapper and convention around the `onChange`/`setState()` pattern. It doesn't fundamentally change how data flows in your React application.
+
+## ReactLink: Before and After
+
+Here's a simple form example without using `ReactLink`:
+
+```javascript
+/** @jsx React.DOM */
+
+var NoLink = React.createClass({
+  getInitialState: function() {
+    return {value: 'Hello!'};
+  },
+  handleChange: function(event) {
+    this.setState({value: event.target.value});
+  },
+  render: function() {
+    var value = this.state.value;
+    return <input type="text" value={value} onChange={this.handleChange} />;
+  }
+});
+```
+
+This works really well and it's very clear how data is flowing, however with a lot of form fields it could get a bit verbose. Let's use `ReactLink` to save us some typing:
+
+```javascript{4,9}
+/** @jsx React.DOM */
+
+var WithLink = React.createClass({
+  mixins: [React.addons.LinkedStateMixin],
+  getInitialState: function() {
+    return {value: 'Hello!'};
+  },
+  render: function() {
+    return <input type="text" valueLink={this.linkState('value')} />;
+  }
+});
+```
+
+`LinkedStateMixin` adds a method ot your React component called `linkState()`. `linkState()` returns a `ReactLink` object which contains the current value of the React state and a callback to change it.
+
+`ReactLink` objects can be passed up and down the tree as props, so it's easy (and explicit) to set up two-way binding between a component deep in the hierarchy and state that lives higher in the hierarchy.
+
+## Under the Hood
+
+There are two sides to `ReactLink`: the place where you create the `ReactLink` instance and the place where you use it. To prove how simple `ReactLink` is, let's rewrite each side separately to be more explicit.
+
+### ReactLink Without LinkedStateMixin
+
+```javascript{7-9,11-14}
+/** @jsx React.DOM */
+
+var WithoutMixin = React.createClass({
+  getInitialState: function() {
+    return {value: 'Hello!'};
+  },
+  handleChange: function(newValue) {
+    this.setState({value: newValue});
+  },
+  render: function() {
+    var valueLink = {
+      value: this.state.value,
+      requestChange: this.handleChange
+    };
+    return <input type="text" valueLink={valueLink} />;
+  }
+});
+```
+
+As you can see, `ReactLink` objects are very simple objects that just have a `value` and `requestChange` prop. And `LinkedStateMixin` is similarly simple: it just populates those fields with a value from `this.state` and a callback that calls `this.setState()`.
+
+### ReactLink Without valueLink
+
+```javascript
+/** @jsx React.DOM */
+
+var WithoutLink = React.createClass({
+  mixins: [React.addons.LinkedStateMixin],
+  getInitialState: function() {
+    return {value: 'Hello!'};
+  },
+  render: function() {
+    var valueLink = this.linkState('value');
+    var handleChange = function(e) {
+      valueLink.requestChange(e.target.value);
+    };
+    return <input type="text" value={valueLink.value} onChange={handleChange} />;
+  }
+});
+```
+
+The `valueLink` prop is also quite simple. It simply handles the `onChange` event and calls `this.props.valueLink.requestChange()` and also uses `this.props.valueLink.value` instead of `this.props.value`. That's it!

+
+`classSet()` is a neat utility for easily manipulating the DOM `class` string.
+
+Here's a common scenario and its solution without `classSet()`:
+
+```javascript
+// inside some `<Message />` React component
+render: function() {
+  var classString = 'message';
+  if (this.props.isImportant) {
+    classString += ' message-important';
+  }
+  if (this.props.isRead) {
+    classString += ' message-read';
+  }
+  // 'message message-important message-read'
+  return <div className={classString}>Great, I'll be there.</div>;
+}
+```
+
+This can quickly get tedious, as assigning class name strings can be hard to read and error-prone. `classSet()` solves this problem:
+
+```javascript
+render: function() {
+  var cx = React.addons.classSet;
+  var classes = cx({
+    'message': true,
+    'message-important': this.props.isImportant,
+    'message-read': this.props.isRead
+  });
+  // same final string, but much cleaner
+  return <div className={classes}>Great, I'll be there.</div>;
+}
+```
+
+When using `classSet()`, pass an object with keys of the CSS class names you might or might not need. Truthy values will result in the key being a part of the resulting string.
+
+No more hacky string concatenations!

+In React, inline styles are not specified as a string. Instead they are specified with an object whose key is the camelCased version of the style name, and whose value is the style's value, usually a string ([more on that later](/react/tips/style-props-value-px.html)):
+
+```js
+/** @jsx React.DOM */
+
+var divStyle = {
+  color: 'white',
+  backgroundImage: 'url(' + imgUrl + ')',
+  WebkitTransition: 'all' // note the capital 'W' here
+};
+
+React.renderComponent(<div style={divStyle}>Hello World!</div>, mountNode);
+```
+
+Style keys are camelCased in order to be consistent with accessing the properties on DOM nodes from JS (e.g. `node.style.backgroundImage`). Vendor prefixes should begin with a capital letter. This is why `WebkitTransition` has an uppercase "W".

+---
+
+`if-else` statements don't work inside JSX. This is because JSX is just syntactic sugar for function calls and object construction. Take this basic example:
+
+```js
+/** @jsx React.DOM */
+
+// This JSX:
+React.renderComponent(<div id="msg">Hello World!</div>, mountNode);
+
+// Is transformed to this JS:
+React.renderComponent(React.DOM.div({id:"msg"}, "Hello World!"), mountNode);
+```
+
+This means that `if` statements don't fit in. Take this example:
+
+```js
+/** @jsx React.DOM */
+
+// This JSX:
+<div id={if (condition) { 'msg' }}>Hello World!</div>
+
+// Is transformed to this JS:
+React.DOM.div({id: if (condition) { 'msg' }}, "Hello World!");
+```
+
+That's not valid JS. You probably want to make use of a ternary expression:
+
+```js
+/** @jsx React.DOM */
+
+React.renderComponent(<div id={condition ? 'msg' : ''}>Hello World!</div>, mountNode);
+```
+
+Try using it today with the [JSX compiler](/react/jsx-compiler.html).

+
+Sometimes you _do_ want to keep the CSS properties unitless. Here's a list of properties that won't get the automatic "px" suffix:

+`componentWillReceiveProps` isn't triggered after the node is put on scene. This is by design. Check out [other lifecycle methods](/react/docs/component-specs.html) for the one that suits your needs.
+
+The reason for that is because `componentWillReceiveProps` often handles the logic of comparing with the old props and acting upon changes; not triggering it at mounting (where there are no old props) helps in defining what the method does.

+
+Using props, passed down from parent, to generate state in `getInitialState` often leads to duplication of "source of truth", i.e. where the real data is. Whenever possible, compute values on-the-fly to ensure that they don't get out of sync later on and cause maintenance trouble.

+
+`componentDidMount` is called after the component is mounted and has a DOM representation. This is often a place where you would attach generic DOM events.
+
+Notice that the event callback is bound to the react component and not the original element. React automatically binds methods to the current component instance for you through a process of [autobinding](../docs/interactivity-and-dynamic-uis.html#under-the-hood-autobinding-and-event-delegation).

+# react
+
+An npm package to get you immediate access to [React](http://facebook.github.io/react/),
+without also requiring the JSX transformer. This is especially useful for cases where you
+want to [`browserify`](https://github.com/substack/node-browserify) your module using
+`React`.
+
+## The `react` npm package has recently changed!
+
+If you're looking for jeffbski's [React.js](https://github.com/jeffbski/react) project, it's now in `npm` as `autoflow` rather than `react`.
+
+## Example Usage
+
+```js
+
+// Previously, you might access React with react-tools.
+var React = require('react-tools').React;
+
+// Now you can access React directly with react-core.
+var React = require('react');
+
+// You can also access ReactWithAddons.
+var React = require('react/addons');
+```
