Reviewer's Guide by SourceryThis PR upgrades react-dom from version 18.3.1 to 19.0.0. This is a major version upgrade and may introduce breaking changes. React 19 introduces several new features, including Actions, useActionState, useOptimistic, use, ref as a prop, Suspense sibling pre-warming, form action prop, useFormStatus, support for document metadata, stylesheets, async scripts, and preloading resources. It also includes some deprecations and breaking changes, such as requiring the new JSX transform, changes to error handling, removal of propTypes, defaultProps for functions, contextTypes, getChildContext, string refs, module pattern factories, React.createFactory, react-test-renderer/shallow, react-dom/test-utils, ReactDOM.render, ReactDOM.hydrate, unmountComponentAtNode, and ReactDOM.findDOMNode.

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
startTransitioncan now accept async functions. Functions passed tostartTransitionare 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 formactionprop 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,useaccepts a promise or Context. If provided a promise,usewill suspend until a value is resolved.usecan only be used in render but can be called conditionally.refas a prop: Refs can now be used as props, removing the need forforwardRef.React DOM Client
<form> actionprop: Form Actions allow you to manage forms automatically and integrate withuseFormStatus. When a<form> actionsucceeds, React will automatically reset the form for uncontrolled components. The form can be reset manually with the newrequestFormResetAPI.<button> and <input> formActionprop: Actions can be passed to theformActionprop 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, andpreconnectAPIs 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
prerenderandprerenderToNodeStreamAPIs 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.refaccess: React 19 supports ref as a prop, so we’re deprecatingelement.refin 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
onUncaughtErrorandonCaughtErrormethods tocreateRootandhydrateRootto customize this error handling.propTypes: UsingpropTypeswill now be silently ignored. If required, we recommend migrating to TypeScript or another type-checking solution.defaultPropsfor functions: ES6 default parameters can be used in place. Class components continue to supportdefaultPropssince there is no ES6 alternative.contextTypesandgetChildContext: Legacy Context for class components has been removed in favor of thecontextTypeAPI.React.createFactory: Now that JSX is broadly supported, allcreateFactoryusage 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 movedactfromreact-dom/test-utilsto react. All other utilities have been removed.ReactDOM.render,ReactDOM.hydrate: These have been removed in favor of the concurrent equivalents:ReactDOM.createRootandReactDOM.hydrateRoot.unmountComponentAtNode: Removed in favor ofroot.unmount().ReactDOM.findDOMNode: You can replaceReactDOM.findDOMNodewith DOM Refs.Notable Changes
React
<Context>as a provider: You can now render<Context>as a provider instead of<Context.Provider>.useDeferredValueinitial value argument: When provided,useDeferredValuewill return the initial value for the initial render of a component, then schedule a re-render in the background with thedeferredValuereturned.useMemoanduseCallbackwill 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
TypeScript Changes
The most common changes can be codemodded with
npx types-react-codemod@latest preset-19 ./path-to-your-react-ts-files.ReactChild(replacement:React.ReactElement | number | string)ReactFragment(replacement:Iterable<React.ReactNode>)ReactNodeArray(replacement:ReadonlyArray<React.ReactNode>)ReactText(replacement:number | string)VoidFunctionComponent(replacement:FunctionComponent)VFC(replacement:FC)prop-types:Requireable,ValidationMap,Validator,WeakValidationMapcreate-react-class:ClassicComponentClass,ClassicComponent,ClassicElement,ComponentSpec,Mixin,ReactChildren,ReactHTML,ReactSVG,SFCFactoryuseRef: The initial argument is now required to matchuseState,createContextetcuseRef()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.ReactElementtyping: The props of React elements now default tounknowninstead ofanyif the element is typed asReactElementJSXnamespace is removed to improve interoperability with other libraries using JSX. Instead, the JSX namespace is available from the React package:import { JSX } from 'react'useReducertypings: MostuseReducerusage should not require explicit type arguments.For example,
