Changelog

React Core

重大改进

  • 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

废弃

  • 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 修复

  • 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

重大改进

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

Bug 修复

  • Fixed some issues with CSS Transitions

JSX

重大改进

  • 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 修复

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

React.js 是 非死book 推出的一个用来构建用户界面的 JavaScript 库。

非死book开源了React，这是该公司用于构建反应式图形界面的JavaScript库，已经应用于构建Instagram网站及 非死book部分网站。最近出现了AngularJS、MeteorJS 和Polymer中实现的Model-Driven Views等框架，React也顺应了这种趋势。React基于在数据模型之上声明式指定用户界面的理念，用户界面会自动与底层数据保持同步。与前面提及 的框架不同，出于灵活性考虑，React使用JavaScript来构建用户界面，没有选择HTML。
