Changelog

React Core

重大改進

• key and ref moved off props object, now accessible on the element directly

• React is now BSD licensed with accompanying Patents grant

• Default prop resolution has moved to Element creation time instead of mount time, making them effectively static

• React.__internals is removed - it was exposed for DevTools which no longer needs access

• Composite Component functions can no longer be called directly - they must be wrapped with React.createFactory first. This is handled for you when using JSX.

新特性

• Spread operator ({...}) introduced to deprecate this.transferPropsTo

• Added support for more HTML attributes: acceptCharset, classID, manifest

廢棄

• React.renderComponent --> React.render

• React.renderComponentToString --> React.renderToString

• React.renderComponentToStaticMarkup --> React.renderToStaticMarkup

• React.isValidComponent --> React.isValidElement

• React.PropTypes.component --> React.PropTypes.element

• React.PropTypes.renderable --> React.PropTypes.node

• DEPRECATED React.isValidClass

• DEPRECATED instance.transferPropsTo

• DEPRECATED Returning false from event handlers to preventDefault

• DEPRECATED Convenience Constructor usage as function, instead wrap with React.createFactory

• DEPRECATED use of key={null} to assign implicit keys

Bug 修復

• Better handling of events and updates in nested results, fixing value restoration in "layered" controlled components

• Correctly treat event.getModifierState as case sensitive

• Improved normalization of event.charCode

• Better error stacks when involving autobound methods

• Removed DevTools message when the DevTools are installed

• Correctly detect required language features across browsers

• Fixed support for some HTML attributes:

• list updates correctly now

• scrollLeft, scrollTop removed, these should not be specified as props

• Improved error messages

React With Addons

新特性

• React.addons.batchedUpdates added to API for hooking into update cycle

重大改進

• React.addons.update uses assign instead of copyProperties which does hasOwnProperty checks. Properties on prototypes will no longer be updated correctly.

Bug 修復

• Fixed some issues with CSS Transitions

JSX

重大改進

• Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components

• JSX no longer transforms to simple function calls

新特性

• @jsx React.DOM no longer required

• spread ({...}) operator introduced to allow easier use of props

Bug 修復

• JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)

React.js 是 非死book 推出的一個用來構建用戶界面的 JavaScript 庫。

非死book開源了React，這是該公司用于構建反應式圖形界面的JavaScript庫，已經應用于構建Instagram網站及 非死book部分網站。最近出現了AngularJS、MeteorJS 和Polymer中實現的Model-Driven Views等框架，React也順應了這種趨勢。React基于在數據模型之上聲明式指定用戶界面的理念，用戶界面會自動與底層數據保持同步。與前面提及 的框架不同，出于靈活性考慮，React使用JavaScript來構建用戶界面，沒有選擇HTML。
