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.

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!

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
|
||||
}
|
||||
},
|
||||
```

## Lights Out
|
||||
|
||||
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 doesn’t 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.

## JSX: E4X The Good Parts
|
||||
|
||||
JSX is often compared to the now defunct E4X, [Vjeux](http://blog.vjeux.com/) went over all the E4X features and explained how JSX is different and hopefully doesn't repeat the same mistakes.
|
||||
|
||||
> E4X (ECMAScript for XML) is a Javascript syntax extension and a runtime to manipulate XML. It was promoted by Mozilla but failed to become mainstream and is now deprecated. JSX was inspired by E4X. In this article, I'm going to go over all the features of E4X and explain the design decisions behind JSX.
|
||||
>
|
||||
> **Historical Context**
|
||||
>
|
||||
> E4X has been created in 2002 by John Schneider. This was the golden age of XML where it was being used for everything: data, configuration files, code, interfaces (DOM) ... E4X was first implemented inside of Rhino, a Javascript implementation from Mozilla written in Java.

## 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 });
|
||||
},
|
||||
componentWillUnmount: function () {
|
||||
socket.removeListener('component-change', this.change);
|
||||

||||
```javascript
|
||||
/* style.css */
|
||||
MyComponent {
|
||||
font-size: 12px;

## ngReact
|
||||
|
||||
[David Chang](http://davidandsuzi.com/) working at [HasOffer](http://www.hasoffers.com/) wanted to speed up his Angular app and replaced Angular primitives by React at different layers. When using React naively it is 67% faster, but when combining it with angular's transclusion it is 450% slower.
|
||||
|
||||
> 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!

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).

|
||||
|
||||
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.
|
||||

||||

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.
|
||||
|
||||
> As I do more projects with ReactJS I started to extract a baseline to use when starting new projects. This is very opinionated and I change my opinion from time to time. This is by no ways perfect and in your opinion most likely wrong :).. which is why I love github
|
||||
>
|
||||
> I encourage you to fork, and make it right and submit a pull request!
|
||||
>
|
||||
> My current opinion is using tools like Grunt, Browserify, Bower and mutiple grunt plugins to get the job done. I also opted for Zepto over jQuery and the Flatiron Project's Director when I need a router. Oh and for the last little bit of tech that makes you mad, I am in the SASS camp when it comes to stylesheets

|
||||
|
||||
> First of all I think it’s important to evaluate technologies on objective rather than subjective features. “It feels nicer” or “it’s cleaner” aren’t valid reasons: performance, modularity, community size and ease of testing / integration with other tools are.

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.

## 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. It’s not about templates, or data binding, or DOM manipulation. It’s about using functional programming with a virtual DOM representation to build ambitious, high-performance apps with JavaScript.

## 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">
|
||||
<body>
|
||||
<header>
|
||||
<h1>Header placeholder</h1>
|
||||
<ul id="navigation">
|
||||
<li class="nav-item"><a href="#">Placeholder</a></li>
|
||||
</ul>
|
||||
</header>
|
||||
<div class="content">place holder</div>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
```clojure
|
||||
...
|
||||
|
||||
(defn my-nav-item [[caption func]]
|
||||
(kioo/component "main.html" [:.nav-item]
|
||||
{[:a] (do-> (content caption)
|
||||
(set-attr :onClick func))}))
|
||||
|
||||
(defn my-header [heading nav-elms]
|
||||
(kioo/component "main.html" [:header]
|
||||
{[:h1] (content heading)
|
||||
[:ul] (content (map my-nav-item nav-elms))}))
|
||||
|
||||
(defn my-page [data]
|
||||
(kioo/component "main.html"
|
||||
{[:header] (substitute (my-header (:heading data)
|
||||
(:navigation data)))
|
||||
[:.content] (content (:content data))}))
|
||||
|
||||
(def app-state (atom {:heading "main"
|
||||
:content "Hello World"
|
||||
:navigation [["home" #(js/alert %)]
|
||||
["next" #(js/alert %)]]}))
|
||||
|
||||
(om/root app-state my-page (.-body js/document))
|
||||
```
|
||||
|
||||
## 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.

### 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.

|
||||
|
||||
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.

|
||||
|
||||
> 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.

### 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).

### "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.

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
|
||||
|
||||
#### 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`
|
||||
- Added support for more attributes:
|
||||
- `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
|
||||
- `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

**JSX lets you write JavaScript function calls with HTML syntax.** To generate a link in React using pure JavaScript you'd write: `React.DOM.a({href: 'http://facebook.github.io/react/'}, 'Hello React!')`.

You may be thinking that it's expensive to react to changing data if there are a large number of nodes under an owner. The good news is that JavaScript is fast and `render()` methods tend to be quite simple, so in most applications this is extremely fast. Additionally, the bottleneck is almost always the DOM mutation and not JS execution and React will optimize this for you using batching and change detection.

|

- `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).

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.

Here, `componentWillMount` is a method called automatically by React before a component is rendered. The key to dynamic updates is the call to `this.setState()`. We replace the old array of comments with the new one from the server and the UI automatically updates itself. Because of this reactivity, it is trivial to add live updates. We will use simple polling here but you could easily use WebSockets or other technologies.

We provide two versions of React: an uncompressed version for development and a minified version for production. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.
|
||||
|
||||
If you're just starting out, make sure to use the development version.

For communication between two components that don't have a parent-child relationship, you can set up your own global event system. Subscribe to events in `componentDidMount()`, unsubscribe in `componentWillUnmount()`, and when you receive an event, call `setState()`.

Say a list of todos, which upon clicking get removed. If there's only one unfinished todo left, animate it:

this.setState({items: items}, function() {

if (items.length === 1) {

this.refs.item0.animate();
|

Alternatively, you could have achieved this by passing the `todo` an `isLastUnfinishedItem` prop, let it check this prop in `componentDidUpdate`, then animate itself; however, this quickly gets messy if you pass around different props to control animations.

If you're using React components in a larger non-React application or transitioning your code to React, you may need to keep references to components. `React.renderComponent` returns a reference to the mounted component:
|
||||
|
||||
```js
|
||||
/** @jsx React.DOM */
|
||||
|
||||
var myComponent = React.renderComponent(<MyComponent />, myContainer);
|
||||
```
|
||||
|
||||
If you pass a variable to 'React.renderComponent`, it's not guaranteed that the component passed in will be the one that's mounted. In cases where you construct a component before mounting it, be sure to reassign your variable:
|
||||
|
||||
```js
|
||||
/** @jsx React.DOM */
|
||||
|
||||
var myComponent = <MyComponent />;
|
||||
|
||||
// Some code here...
|
||||
|
||||
myComponent = React.renderComponent(myComponent, myContainer);
|
||||
```
|
||||
|
||||
> Note:
|
||||
>
|
||||
> This should only ever be used at the top level. Inside components, let your `props` and `state` handle communication with child components, and only reference components via `ref`s.

An npm package to get you immediate access to [React](http://facebook.github.io/react/),

||||
var React = require('react');
