Bumps react-dom from 18.3.1 to 19.2.3.

Release notes

Sourced from react-dom's releases.

19.2.3 (December 11th, 2025)

React Server Components

19.2.2 (December 11th, 2025)

React Server Components

19.2.1 (December 3rd, 2025)

React Server Components

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:
  • Added resume APIs for partial pre-rendering with Node Streams:
  • 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)
