[dependabot[bot]]

Bumps react-dom from 18.3.1 to 19.2.1.

Release notes

Sourced from react-dom's releases.

19.2.1 (December 3rd, 2025)

React Server Components

• Bring React Server Component fixes to Server Actions (@​sebmarkbage #35277)

19.2.0 (Oct 1, 2025)

Below is a list of all new features, APIs, and bug fixes.

Read the React 19.2 release post for more information.

New React Features

• <Activity>: A new API to hide and restore the UI and internal state of its children.
• useEffectEvent is a React Hook that lets you extract non-reactive logic into an Effect Event.
• cacheSignal (for RSCs) lets your know when the cache() lifetime is over.
• React Performance tracks appear on the Performance panel’s timeline in your browser developer tools

New React DOM Features

• Added resume APIs for partial pre-rendering with Web Streams:
  • resume: to resume a prerender to a stream.
  • resumeAndPrerender: to resume a prerender to HTML.
• Added resume APIs for partial pre-rendering with Node Streams:
  • resumeToPipeableStream: to resume a prerender to a stream.
  • resumeAndPrerenderToNodeStream: to resume a prerender to HTML.
• Updated prerender APIs to return a postponed state that can be passed to the resume APIs.

Notable changes

• React DOM now batches suspense boundary reveals, matching the behavior of client side rendering. This change is especially noticeable when animating the reveal of Suspense boundaries e.g. with the upcoming <ViewTransition> Component. React will batch as much reveals as possible before the first paint while trying to hit popular first-contentful paint metrics.
• Add Node Web Streams (prerender, renderToReadableStream) to server-side-rendering APIs for Node.js
• Use underscore instead of : IDs generated by useId

All Changes

React

• <Activity /> was developed over many years, starting before ClassComponent.setState (@​acdlite @​sebmarkbage and many others)
• Stringify context as "SomeContext" instead of "SomeContext.Provider" (@​kassens #33507)
• Include stack of cause of React instrumentation errors with %o placeholder (@​eps1lon #34198)
• Fix infinite useDeferredValue loop in popstate event (@​acdlite #32821)
• Fix a bug when an initial value was passed to useDeferredValue (@​acdlite #34376)
• Fix a crash when submitting forms with Client Actions (@​sebmarkbage #33055)
• Hide/unhide the content of dehydrated suspense boundaries if they resuspend (@​sebmarkbage #32900)
• Avoid stack overflow on wide trees during Hot Reload (@​sophiebits #34145)
• Improve Owner and Component stacks in various places (@​sebmarkbage, @​eps1lon: #33629, #33724, #32735, #33723)
• Add cacheSignal (@​sebmarkbage #33557)

React DOM

• Block on Suspensey Fonts during reveal of server-side-rendered content (@​sebmarkbage #33342)
