React
- Backport support for the new JSX transform to 0.14.x. (@lunaruan in #18299 and @gaearon in #20024)
v0.14.0
Major changes
- Split the main
react
package into two:react
andreact-dom
. This paves the way to writing components that can be shared between the web version of React and React Native. This means you will need to include both files and some functions have been moved fromReact
toReactDOM
. - Addons have been moved to separate packages (
react-addons-clone-with-props
,react-addons-create-fragment
,react-addons-css-transition-group
,react-addons-linked-state-mixin
,react-addons-perf
,react-addons-pure-render-mixin
,react-addons-shallow-compare
,react-addons-test-utils
,react-addons-transition-group
,react-addons-update
,ReactDOM.unstable_batchedUpdates
). - Stateless functional components - React components were previously created using React.createClass or using ES6 classes. This release adds a new syntax where a user defines a single stateless render function (with one parameter:
props
) which returns a JSX element, and this function may be used as a component. - Refs to DOM components as the DOM node itself. Previously the only useful thing you can do with a DOM component is call
getDOMNode()
to get the underlying DOM node. Starting with this release, a ref to a DOM component is the actual DOM node. Note that refs to custom (user-defined) components work exactly as before; only the built-in DOM components are affected by this change.
Breaking changes
-
React.initializeTouchEvents
is no longer necessary and has been removed completely. Touch events now work automatically. - Add-Ons: Due to the DOM node refs change mentioned above,
TestUtils.findAllInRenderedTree
and related helpers are no longer able to take a DOM component, only a custom component. - The
props
object is now frozen, so mutating props after creating a component element is no longer supported. In most cases,React.cloneElement
should be used instead. This change makes your components easier to reason about and enables the compiler optimizations mentioned above. - Plain objects are no longer supported as React children; arrays should be used instead. You can use the
createFragment
helper to migrate, which now returns an array. - Add-Ons:
classSet
has been removed. Use classnames instead. - Web components (custom elements) now use native property names. Eg:
class
instead ofclassName
.
Deprecations
-
this.getDOMNode()
is now deprecated andReactDOM.findDOMNode(this)
can be used instead. Note that in the common case,findDOMNode
is now unnecessary since a ref to the DOM component is now the actual DOM node. -
setProps
andreplaceProps
are now deprecated. Instead, call ReactDOM.render again at the top level with the new props. - ES6 component classes must now extend
React.Component
in order to enable stateless function components. The ES3 module pattern will continue to work. - Reusing and mutating a
style
object between renders has been deprecated. This mirrors our change to freeze theprops
object. - Add-Ons:
cloneWithProps
is now deprecated. UseReact.cloneElement
instead (unlikecloneWithProps
,cloneElement
does not mergeclassName
orstyle
automatically; you can merge them manually if needed). - Add-Ons: To improve reliability,
CSSTransitionGroup
will no longer listen to transition events. Instead, you should specify transition durations manually using props such astransitionEnterTimeout={500}
.
Notable enhancements
- Added
React.Children.toArray
which takes a nested children object and returns a flat array with keys assigned to each child. This helper makes it easier to manipulate collections of children in yourrender
methods, especially if you want to reorder or slicethis.props.children
before passing it down. In addition,React.Children.map
now returns plain arrays too. - React uses
console.error
instead ofconsole.warn
for warnings so that browsers show a full stack trace in the console. (Our warnings appear when you use patterns that will break in future releases and for code that is likely to behave unexpectedly, so we do consider our warnings to be “must-fix” errors.) - Previously, including untrusted objects as React children could result in an XSS security vulnerability. This problem should be avoided by properly validating input at the application layer and by never passing untrusted objects around your application code. As an additional layer of protection, React now tags elements with a specific ES2015 (ES6)
Symbol
in browsers that support it, in order to ensure that React never considers untrusted JSON to be a valid element. If this extra security protection is important to you, you should add aSymbol
polyfill for older browsers, such as the one included by Babel’s polyfill. - When possible, React DOM now generates XHTML-compatible markup.
- React DOM now supports these standard HTML attributes:
capture
,challenge
,inputMode
,is
,keyParams
,keyType
,minLength
,summary
,wrap
. It also now supports these non-standard attributes:autoSave
,results
,security
. - React DOM now supports these SVG attributes, which render into namespaced attributes:
xlinkActuate
,xlinkArcrole
,xlinkHref
,xlinkRole
,xlinkShow
,xlinkTitle
,xlinkType
,xmlBase
,xmlLang
,xmlSpace
. - The
image
SVG tag is now supported by React DOM. - In React DOM, arbitrary attributes are supported on custom elements (those with a hyphen in the tag name or an
is="..."
attribute). - React DOM now supports these media events on
audio
andvideo
tags:onAbort
,onCanPlay
,onCanPlayThrough
,onDurationChange
,onEmptied
,onEncrypted
,onEnded
,onError
,onLoadedData
,onLoadedMetadata
,onLoadStart
,onPause
,onPlay
,onPlaying
,onProgress
,onRateChange
,onSeeked
,onSeeking
,onStalled
,onSuspend
,onTimeUpdate
,onVolumeChange
,onWaiting
. - Many small performance improvements have been made.
- Many warnings show more context than before.
- Add-Ons: A
shallowCompare
add-on has been added as a migration path forPureRenderMixin
in ES6 classes. - Add-Ons:
CSSTransitionGroup
can now use custom class names instead of appending-enter-active
or similar to the transition name.
New helpful warnings
- React DOM now warns you when nesting HTML elements invalidly, which helps you avoid surprising errors during updates.
- Passing
document.body
directly as the container toReactDOM.render
now gives a warning as doing so can cause problems with browser extensions that modify the DOM. - Using multiple instances of React together is not supported, so we now warn when we detect this case to help you avoid running into the resulting problems.
Notable bug fixes
- Click events are handled by React DOM more reliably in mobile browsers, particularly in Mobile Safari.
- SVG elements are created with the correct namespace in more cases.
- React DOM now renders
<option>
elements with multiple text children properly and renders<select>
elements on the server with the correct option selected. - When two separate copies of React add nodes to the same document (including when a browser extension uses React), React DOM tries harder not to throw exceptions during event handling.
- Using non-lowercase HTML tag names in React DOM (e.g.,
React.createElement('DIV')
) no longer causes problems, though we continue to recommend lowercase for consistency with the JSX tag name convention (lowercase names refer to built-in components, capitalized names refer to custom components). - React DOM understands that these CSS properties are unitless and does not append “px” to their values:
animationIterationCount
,boxOrdinalGroup
,flexOrder
,tabSize
,stopOpacity
. - Add-Ons: When using the test utils,
Simulate.mouseEnter
andSimulate.mouseLeave
now work. - Add-Ons: ReactTransitionGroup now correctly handles multiple nodes being removed simultaneously.
React Tools / Babel
Breaking Changes
- The
react-tools
package andJSXTransformer.js
browser file have been deprecated. You can continue using version0.13.3
of both, but we no longer support them and recommend migrating to Babel, which has built-in support for React and JSX.
New Features
- Babel 5.8.24 introduces Inlining React elements: The
optimisation.react.inlineElements
transform converts JSX elements to object literals like{type: 'div', props: ...}
instead of calls toReact.createElement
. This should only be enabled in production, since it disables some development warnings/checks. - Babel 5.8.24 introduces Constant hoisting for React elements: The
optimisation.react.constantElements
transform hoists element creation to the top level for subtrees that are fully static, which reduces calls toReact.createElement
and the resulting allocations. More importantly, it tells React that the subtree hasn’t changed so React can completely skip it when reconciling. This should only be enabled in production, since it disables some development warnings/checks.
v0.13.3

) are treated as DOM components - Perf: Stop double-counting DOM components
React Tools
Bug Fixes
- Fix option parsing for
--non-strict-es6module
v0.13.0
React Core
Breaking Changes
- Deprecated patterns that warned in 0.12 no longer work: most prominently, calling component classes without using JSX or React.createElement and using non-component functions with JSX or createElement
- Mutating
props
after an element is created is deprecated and will cause warnings in development mode; future versions of React will incorporate performance optimizations assuming that props aren't mutated - Static methods (defined in
statics
) are no longer autobound to the component class -
ref
resolution order has changed slightly such that a ref to a component is available immediately after itscomponentDidMount
method is called; this change should be observable only if your component calls a parent component's callback within yourcomponentDidMount
, which is an anti-pattern and should be avoided regardless - Calls to
setState
in life-cycle methods are now always batched and therefore asynchronous. Previously the first call on the first mount was synchronous. -
setState
andforceUpdate
on an unmounted component now warns instead of throwing. That avoids a possible race condition with Promises. - Access to most internal properties has been completely removed, including
this._pendingState
andthis._rootNodeID
.
New Features
- Support for using ES6 classes to build React components; see the v0.13.0 beta 1 notes for details.
- Added new top-level API
React.findDOMNode(component)
, which should be used in place ofcomponent.getDOMNode()
. The base class for ES6-based components will not havegetDOMNode
. This change will enable some more patterns moving forward. - Added a new top-level API
React.cloneElement(el, props)
for making copies of React elements – see the v0.13 RC2 notes for more details. - New
ref
style, allowing a callback to be used in place of a name:<Photo ref={(c) => this._photo = c} />
allows you to reference the component withthis._photo
(as opposed toref="photo"
which givesthis.refs.photo
). -
this.setState()
can now take a function as the first argument for transactional state updates, such asthis.setState((state, props) => ({count: state.count + 1}));
– this means that you no longer need to usethis._pendingState
, which is now gone. - Support for iterators and immutable-js sequences as children.
Deprecations
-
ComponentClass.type
is deprecated. Just useComponentClass
(usually aselement.type === ComponentClass
). - Some methods that are available on
createClass
-based components are removed or deprecated from ES6 classes (getDOMNode
,replaceState
,isMounted
,setProps
,replaceProps
).
React with Add-Ons
New Features
-
React.addons.createFragment
was added for adding keys to entire sets of children.
Deprecations
-
React.addons.classSet
is now deprecated. This functionality can be replaced with several freely available modules. classnames is one such module. - Calls to
React.addons.cloneWithProps
can be migrated to useReact.cloneElement
instead – make sure to mergestyle
andclassName
manually if desired.
React Tools
Breaking Changes
- When transforming ES6 syntax,
class
methods are no longer enumerable by default, which requiresObject.defineProperty
; if you support browsers such as IE8, you can pass--target es3
to mirror the old behavior
New Features
-
--target
option is available on the jsx command, allowing users to specify and ECMAScript version to target.-
es5
is the default. -
es3
restores the previous default behavior. An additional transform is added here to ensure the use of reserved words as properties is safe (egthis.static
will becomethis['static']
for IE8 compatibility).
-
- The transform for the call spread operator has also been enabled.
JSXTransformer
Breaking Changes
- The return value of
transform
now containssourceMap
as a JS object already, not an instance ofSourceMapGenerator
.
JSX
Breaking Changes
- A change was made to how some JSX was parsed, specifically around the use of
>
or}
when inside an element. Previously it would be treated as a string but now it will be treated as a parse error. Thejsx_orphaned_brackets_transformer
package on npm can be used to find and fix potential issues in your JSX code.
v0.12.2
React Core
- Added support for more HTML attributes:
formAction
,formEncType
,formMethod
,formTarget
,marginHeight
,marginWidth
- Added
strokeOpacity
to the list of unitless CSS properties - Removed trailing commas (allows npm module to be bundled and used in IE8)
- Fixed bug resulting in error when passing
undefined
toReact.createElement
- now there is a useful warning
React Tools
- JSX-related transforms now always use double quotes for props and
displayName
v0.12.1
React Tools
- Types transform updated with latest support
- jstransform version updated with improved ES6 transforms
- Explicit Esprima dependency removed in favor of using Esprima information exported by jstransform
v0.12.0
React Core
Breaking Changes
-
key
andref
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.
New Features
- Spread operator (
{...}
) introduced to deprecatethis.transferPropsTo
- Added support for more HTML attributes:
acceptCharset

v0.5.0
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.
- Support for additional DOM properties (
charSet
,content
,form
,httpEquiv
,rowSpan
,autoCapitalize
). - Support for additional SVG properties (
rx
,ry
). - Support for using
getInitialState
andgetDefaultProps
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
toReact.unmountComponentAtNode
. - Began laying down work for refined performance analysis.
- Better support for server-side rendering - 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. 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.
JSX
- No longer transform
class
toclassName
as part of the transform! This is a breaking change - if you were usingclass
, you must change this toclassName
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.
v0.3.0
- Initial public release
v0.0.0-experimental-aae83a4b9
