Release Notes

reduxjs/react-redux (react-redux)

v9.0.4

Compare Source

This bugfix release updates the React Native peer dependency to be >= 0.69, to better reflect the need for React 18 compat and (hopefully) resolve issues with the npm package manager throwing peer dep errors on install.

What's Changed

v9.0.3

Compare Source

This bugfix release drops the ReactDOM / React Native specific use of render batching, as React 18 now automatically batches, and updates the React types dependencies

Changelog

Batching Dependency Updates

React-Redux has long depended on React's unstable_batchedUpdates API to help batch renders queued by Redux updates. It also re-exported that method as a util named batch.

However, React 18 now auto-batches all queued renders in the same event loop tick, so unstable_batchedUpdates is effectively a no-op.

Using unstable_batchedUpdates has always been a pain point, because it's exported by the renderer package (ReactDOM or React Native), rather than the core react package. Our prior implementation relied on having separate batch.ts and batch.native.ts files in the codebase, and expecting React Native's bundler to find the right transpiled file at app build time. Now that we're pre-bundling artifacts in React-Redux v9, that approach has become a problem.

Given that React 18 already batches by default, there's no further need to continue using unstable_batchedUpdates internally, so we've removed our use of that and simplified the internals.

We still export a batch method, but it's effectively a no-op that just immediately runs the given callback, and we've marked it as @deprecated.

We've also updated the build artifacts and packaging, as there's no longer a need for an alternate-renderers entry point that omits batching, or a separate artifact that imports from "react-native".

v9.0.1

Compare Source

This bugfix release updates the package to include a new react-redux.react-native.js bundle that specifically imports React Native, and consolidates all of the 'react' imports into one file to save on bundle size (and enable some tricky React Native import handling).

What's Changed

Full Changelog: reduxjs/react-redux@v9.0.0...v9.0.1

v9.0.0

Compare Source

This major release:

  • Switches to requiring React 18 and Redux Toolkit 2.0 / Redux 5.0
  • Updates the packaging for better ESM/CJS compatibility and modernizes the build output
  • Updates the options for dev mode checks in useSelector
  • Adds a new React Server Components artifact that throws on use, to better indicate compat issues

This release has breaking changes.

This release is part of a wave of major versions of all the Redux packages: Redux Toolkit 2.0, Redux core 5.0, React-Redux 9.0, Reselect 5.0, and Redux Thunk 3.0.

For full details on all of the breaking changes and other significant changes to all of those packages, see the "Migrating to RTK 2.0 and Redux 5.0" migration guide in the Redux docs.

[!NOTE]
The Redux core, Reselect, and Redux Thunk packages are included as part of Redux Toolkit, and RTK users do not need to manually upgrade them - you'll get them as part of the upgrade to RTK 2.0. (If you're not using Redux Toolkit yet, please start migrating your existing legacy Redux code to use Redux Toolkit today!)
React-Redux is a separate, package, but we expect you'll be upgrading them together.

Changelog
React 18 and RTK 2 / Redux core 5 Are Required

React-Redux 7.x and 8.x worked with all versions of React that had hooks (16.8+, 17.x, 18.x). However, React-Redux v8 used React 18's new useSyncExternalStore hook. In order to maintain backwards compatibility with older React versions, we used the use-sync-external-store "shim" package that provided an official userland implementation of the useSyncExternalStore hook when used with React 16 or 17. This meant that if you were using React 18, there were a few hundred extra bytes of shim code being imported even though it wasn't needed.

For React-Redux v9, we're switching so that React 18 is now required! This both simplifies the maintenance burden on our side (fewer versions of React to test against), and also lets us drop the extra bytes because we can import useSyncExternalStore directly.

React 18 has been out for a year and a half, and other libraries like React Query are also switching to require React 18 in their next major version. This seems like a reasonable time to make that switch.

Similarly, React-Redux now depends on Redux core v5 for updated TS types (but not runtime behavior). We strongly encourage all Redux users to be using Redux Toolkit, which already includes the Redux core. Redux Toolkit 2.0 comes with Redux core 5.0 built in.

ESM/CJS Package Compatibility

The biggest theme of the Redux v5 and RTK 2.0 releases is trying to get "true" ESM package publishing compatibility in place, while still supporting CJS in the published package.

The primary build artifact is now an ESM file, dist/react-redux.mjs. Most build tools should pick this up. There's also a CJS artifact, and a second copy of the ESM file named react-redux.legacy-esm.js to support Webpack 4 (which does not recognize the exports field in package.json). There's also two special-case artifacts: an "alternate renderers" artifact that should be used for any renderer other than ReactDOM or React Native (such as the ink React CLI renderer), and a React Server Components artifact that throws when any import is used (since using hooks or context would error anyway in an RSC environment). Additionally, all of the build artifacts now live under ./dist/ in the published package.

Previous releases actually shipped separate individual transpiled source files - the build artifacts are now pre-bundled, same as the rest of the Redux libraries.

Modernized Build Output

We now publish modern JS syntax targeting ES2020, including optional chaining, object spread, and other modern syntax. If you need to

Build Tooling

We're now building the package using https://github.com/egoist/tsup. We also now include sourcemaps for the ESM and CJS artifacts.

Dropping UMD Builds

Redux has always shipped with UMD build artifacts. These are primarily meant for direct import as script tags, such as in a CodePen or a no-bundler build environment.

We've dropped those build artifacts from the published package, on the grounds that the use cases seem pretty rare today.

There's now a react-redux.browser.mjs file in the package that can be loaded from a CDN like Unpkg.

If you have strong use cases for us continuing to include UMD build artifacts, please let us know!

React Server Components Behavior

Per Mark's post "My Experience Modernizing Packages to ESM", one of the recent pain points has been the rollout of React Server Components and the limits the Next.js + React teams have added to RSCs. We see many users try to import and use React-Redux APIs in React Server Component files, then get confused why things aren't working right.

To address that, we've added a new entry point with a "react-server" condition. Every export in that file will throw an error as soon as it's called, to help catch this mistake earlier.

Dev Mode Checks Updated

In v8.1.0, we updated useSelector to accept an options object containing options to check for selectors that always calculate new values, or that always return the root state.

We've renamed the noopCheck option to identityFunctionCheck for clarity. We've also changed the structure of the options object to be:

export type DevModeCheckFrequency = 'never' | 'once' | 'always'

export interface UseSelectorOptions<Selected = unknown> {
  equalityFn?: EqualityFn<Selected>
  devModeChecks?: {
    stabilityCheck?: DevModeCheckFrequency
    identityFunctionCheck?: DevModeCheckFrequency
  }
}
hoist-non-react-statics and react-is Deps Inlined

Higher Order Components have been discouraged in the React ecosystem over the last few years. However, we still include the connect API. It's now in maintenance mode and not in active development.

As described in the React legacy docs on HOCs, one quirk of HOCs is needing to copy over static methods to the wrapper component. The hoist-non-react-statics package has been the standard tool to do that.

We've inlined a copy of hoist-non-react-statics and removed the package dep, and confirmed that this improves tree-shaking.

We've also done the same with the react-is package as well, which was also only used by connect.

This should have no user-facing effects.

TypeScript Support

We've dropped support for TS 4.6 and earlier, and our support matrix is now TS 4.7+.

v8.1.3

Compare Source

v8.1.2

Compare Source

This version changes imports from the React package to namespace imports so the package can safely be imported in React Server Components as long as you don't actually use it - this is for example important if you want to use the React-specifc createApi function from Redux Toolkit.

Some other changes:

  • The behaviour of the "React Context Singletons" from 8.1.1 has been adjusted to also work if you have multiple React instances of the same version (those will now be separated) and if you are in an environment without globalThis (in this case it will fall back to the previous behaviour).
  • We do no longer use Proxies, which should help with some very outdated consumers, e.g. smart TVs, that cannot even polyfill Proxies.

Full Changelog: reduxjs/react-redux@v8.1.1...v8.1.2

v8.1.1

Compare Source

This bugfix release tweaks the recent lazy context setup logic to ensure a single React context instance per React version, and removes the recently added RTK peerdep to fix an issue with Yarn workspaces.

Changelog

React Context Singletons

React Context has always relied on reference identity. If you have two different copies of React or a library in a page, that can cause multiple versions of a context instance to be created, leading to problems like the infamous "Could not find react-redux context" error.

In v8.1.0, we reworked the internals to lazily create our single ReactReduxContext instance to avoid issues in a React Server Components environment.

This release further tweaks that to stash a single context instance per React version found in the page, thus hopefully avoiding the "multiple copies of the same context" error in the future.

What's Changed

v8.1.0

Compare Source

This feature release adds new development-mode safety checks for common errors (like poorly-written selectors), adds a workaround to fix crash errors when React-Redux hooks are imported into React Server Component files, and updates our hooks API docs page with improved explanations and updated links.

Changelog

Development Mode Checks for useSelector

We've had a number of users tell us over time that it's common to accidentally write selectors that have bad behavior and cause performance issues. The most common causes of this are either selectors that unconditionally return a new reference (such as state => state.todos.map() without any memoization ), or selectors that actually return the entire root state ( state => state ).

We've updated useSelector to add safety checks in development mode that warn if these incorrect behaviors are detected:

  • Selectors will be called twice with the same inputs, and useSelector will warn if the results are different references
  • useSelector will warn if the selector result is actually the entire root state

By default, these checks only run once the first time useSelector is called. This should provide a good balance between detecting possible issues, and keeping development mode execution performant without adding many unnecessary extra selector calls.

If you want, you can configure this behavior globally by passing the enum flags directly to <Provider>, or on a per-useSelector basis by passing an options object as the second argument:

// Example: globally configure the root state "noop" check to run every time
<Provider store={store} noopCheck="always">
  {children}
</Provider>
// Example: configure `useSelector` to specifically run the reference checks differently:
function Component() {
  // Disable check entirely for this selector
  const count = useSelector(selectCount, { stabilityCheck: 'never' })
  // run once (default)
  const user = useSelector(selectUser, { stabilityCheck: 'once' })
  // ...
}

This goes along with the similar safety checks we've added to Reselect v5 alpha as well.

Context Changes

We're still trying to work out how to properly use Redux and React Server Components together. One possibility is using RTK Query's createApi to define data fetching endpoints, and using the generated thunks to fetch data in RSCs, but it's still an open question.

However, users have reported that merely importing any React-Redux API in an RSC file causes a crash, because React.createContext is not defined in RSC files. RTKQ's React-specific createApi entry point imports React-Redux, so it's been unusable in RSCs.

This release adds a workaround to fix that issue, by using a proxy wrapper around our singleton ReactReduxContext instance and lazily creating that instance on demand. In testing, this appears to both continue to work in all unit tests, and fixes the import error in an RSC environment. We'd appreciate further feedback in case this change does cause any issues for anyone!

We've also tweaked the internals of the hooks to do checks for correct <Provider> usage when using a custom context, same as the default context checks.

Docs Updates

We've cleaned up some of the Hooks API reference page, and updated links to the React docs.

v8.0.4

Compare Source

This patch release fixes some minor TS types issues, and updates the rarely-used areStatesEqual option for connect to now pass through ownProps for additional use in determining which pieces of state to compare if desired.

Note: 8.0.3 was accidentally published without one of these fixes. Use 8.0.4 instead.

Changelog

TS Fixes

We've fixed an import of React that caused issues with the allowSyntheticDefaultImports TS compiler flag in user projects.

connect already accepted a custom context instance as props.context, and had runtime checks in case users were passing through a real value with app data as props.context instead. However, the TS types did not handle that case, and this would fail to compile. If your own component expects props.context with actual data, connect's types now use that type instead.

The ConnectedProps<T> type had a mismatch with React's built-in React.ComponentProps<Component> type, and that should now work correctly.

Other Changes

The areStatesEqual option to connect now receives ownProps as well, in case you need to make a more specific comparison with certain sections of state.

The new signature is:

{
  areStatesEqual?: (
    nextState: State,
    prevState: State,
    nextOwnProps: TOwnProps,
    prevOwnProps: TOwnProps
  ) => boolean
}
