Next stepsWhat is a deprecated package?The maintainer of the package marked it as deprecated. This could indicate that a single version should not be used, or that the package is no longer maintained and any new vulnerabilities will not be fixed. Research the state of the package and determine if there are non-deprecated versions that can be used, or if it should be replaced with a new, supported solution. What are unpopular packages?This package is not very popular. Unpopular packages may have less maintenance and contain other problems.

Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support [AT] socket [DOT] dev. Remove the packageIf you happen to install a dependency that Socket reports as Known Malware you should immediately remove it and select a different dependency.

Release notes
Package name: react-dom
Below is a list of all new features, APIs, deprecations, and breaking changes. Read React 19 release post and React 19 upgrade guide for more information.
New Features
React
startTransition
can now accept async functions. Functions passed tostartTransition
are called “Actions”. A given Transition can include one or more Actions which update state in the background and update the UI with one commit. In addition to updating state, Actions can now perform side effects including async requests, and the Action will wait for the work to finish before finishing the Transition. This feature allows Transitions to include side effects likefetch()
in the pending state, and provides support for error handling, and optimistic updates.useActionState
: is a new hook to order Actions inside of a Transition with access to the state of the action, and the pending state. It accepts a reducer that can call Actions, and the initial state used for first render. It also accepts an optional string that is used if the action is passed to a formaction
prop to support progressive enhancement in forms.useOptimistic
: is a new hook to update state while a Transition is in progress. It returns the state, and a set function that can be called inside a transition to “optimistically” update the state to expected final value immediately while the Transition completes in the background. When the transition finishes, the state is updated to the new value.use
: is a new API that allows reading resources in render. In React 19,use
accepts a promise or Context. If provided a promise,use
will suspend until a value is resolved.use
can only be used in render but can be called conditionally.ref
as a prop: Refs can now be used as props, removing the need forforwardRef
.React DOM Client
<form> action
prop: Form Actions allow you to manage forms automatically and integrate withuseFormStatus
. When a<form> action
succeeds, React will automatically reset the form for uncontrolled components. The form can be reset manually with the newrequestFormReset
API.<button> and <input> formAction
prop: Actions can be passed to theformAction
prop to configure form submission behavior. This allows using different Actions depending on the input.useFormStatus
: is a new hook that provides the status of the parent<form> action
, as if the form was a Context provider. The hook returns the values:pending
,data
,method
, andaction
.<head>
section of the document.<head>
on the client before revealing the content of a Suspense boundary that depends on that stylesheet.preinit
,preload
,prefetchDNS
, andpreconnect
APIs to optimize initial page loads by moving discovery of additional resources like fonts out of stylesheet loading. They can also be used to prefetch resources used by an anticipated navigation.React DOM Server
prerender
andprerenderToNodeStream
APIs for static site generation. They are designed to work with streaming environments like Node.js Streams and Web Streams. UnlikerenderToString
, they wait for data to load for HTML generation.React Server Components
Deprecations
element.ref
access: React 19 supports ref as a prop, so we’re deprecatingelement.ref
in favor ofelement.props.ref
. Accessing will result in a warning.react-test-renderer
: In React 19, react-test-renderer logs a deprecation warning and has switched to concurrent rendering for web usage. We recommend migrating your tests to @ testinglibrary.com/docs/react-testing-library/intro/) or @ testingesting-library.com/docs/react-native-testing-library/intro)Breaking Changes
React 19 brings in a number of breaking changes, including the removals of long-deprecated APIs. We recommend first upgrading to
18.3.1
, where we've added additional deprecation warnings. Check out the upgrade guide for more details and guidance on codemodding.React
onUncaughtError
andonCaughtError
methods tocreateRoot
andhydrateRoot
to customize this error handling.propTypes
: UsingpropTypes
will now be silently ignored. If required, we recommend migrating to TypeScript or another type-checking solution.defaultProps
for functions: ES6 default parameters can be used in place. Class components continue to supportdefaultProps
since there is no ES6 alternative.contextTypes
andgetChildContext
: Legacy Context for class components has been removed in favor of thecontextType
API.React.createFactory
: Now that JSX is broadly supported, allcreateFactory
usage can be migrated to JSX components.react-test-renderer/shallow
: This has been a re-export of react-shallow-renderer since React 18. If needed, you can continue to use the third-party package directly. We recommend using @ testinglibrary.com/docs/react-testing-library/intro/) or @ testingesting-library.com/docs/react-native-testing-library/intro) instead.React DOM
react-dom/test-utils
: We’ve movedact
fromreact-dom/test-utils
to react. All other utilities have been removed.ReactDOM
.render
,ReactDOM
.hydrate
: These have been removed in favor of the concurrent equivalents:ReactDOM
.createRoot
andReactDOM.hydrateRoot
.unmountComponentAtNode
: Removed in favor ofroot.unmount()
.ReactDOM
.findDOMNode
: You can replaceReactDOM
.findDOMNode
with DOM Refs.Notable Changes
React
<Context>
as a provider: You can now render<Context>
as a provider instead of<Context.Provider>
.useDeferredValue
initial value argument: When provided,useDeferredValue
will return the initial value for the initial render of a component, then schedule a re-render in the background with thedeferredValue
returned.useMemo
anduseCallback
will now reuse the memoized results from the first render, during the second render. Additionally, StrictMode will now double-invoke ref callback functions on initial mount.React DOM

,createContext
etcuseRef()
are now always mutable instead of sometimes being immutable. This feature was too confusing for users and conflicted with legit cases where refs were managed by React and manually written to.ReactElement
typing: The props of React elements now default tounknown

if the element is typed asReactElement
JSX
namespace is removed to improve interoperability with other libraries using JSX. Instead, the JSX namespace is available from the React package:import { JSX } from 'react'
useReducer
typings: MostuseReducer
usage should not require explicit type arguments.For example,
