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".

v9.0.0

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+.

createStore Marked Deprecated

In Redux 4.2.0, we marked the original createStore method as @deprecated. Strictly speaking, this is not a breaking change, nor is it new in 5.0, but we're documenting it here for completeness.

This deprecation is solely a visual indicator that is meant to encourage users to migrate their apps from legacy Redux patterns to use the modern Redux Toolkit APIs.

The deprecation results in a visual strikethrough when imported and used, like createStore, but with no runtime errors or warnings.

createStore will continue to work indefinitely, and will not ever be removed. But, today we want all Redux users to be using Redux Toolkit for all of their Redux logic.

To fix this, there are three options:

  • Follow our strong suggestion to switch over to Redux Toolkit and configureStore
  • Do nothing. It's just a visual strikethrough, and it doesn't affect how your code behaves. Ignore it.
  • Switch to using the legacy_createStore API that is now exported, which is the exact same function but with no @deprecated tag. The simplest option is to do an aliased import rename, like import { legacy_createStore as createStore } from 'redux'
Action types must be strings

We've always specifically told our users that actions and state must be serializable, and that action.type should be a string. This is both to ensure that actions are serializable, and to help provide a readable action history in the Redux DevTools.

store.dispatch(action) now specifically enforces that action.type must be a string and will throw an error if not, in the same way it throws an error if the action is not a plain object.

In practice, this was already true 99.99% of the time and shouldn't have any effect on users (especially those using Redux Toolkit and createSlice), but there may be some legacy Redux codebases that opted to use Symbols as action types.

TypeScript Changes

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

Typescript rewrite

In 2019, we began a community-powered conversion of the Redux codebase to TypeScript. The original effort was discussed in #​3500: Port to TypeScript, and the work was integrated in PR #​3536: Convert to TypeScript.

However, the TS-converted code sat around in the repo for several years, unused and unpublished, due to concerns about possible compatibility issues with the existing ecosystem (as well as general inertia on our part).

Redux core v5 is now built from that TS-converted source code. In theory, this should be almost identical in both runtime behavior and types to the 4.x build, but it's very likely that some of the changes may cause types issues.

Please report any unexpected compatibility issues!!

AnyAction deprecated in favour of UnknownAction

The Redux TS types have always exported an AnyAction type, which is defined to have {type: string} and treat any other field as any. This makes it easy to write uses like console.log(action.whatever), but unfortunately does not provide any meaningful type safety.

We now export an UnknownAction type, which treats all fields other than action.type as unknown. This encourages users to write type guards that check the action object and assert its specific TS type. Inside of those checks, you can access a field with better type safety.

UnknownAction is now the default any place in the Redux source that expects an action object.

AnyAction still exists for compatibility, but has been marked as deprecated.

Note that Redux Toolkit's action creators have a .match() method that acts as a useful type guard:

if (todoAdded.match(someUnknownAction)) {
  // action is now typed as a PayloadAction<Todo>
}

You can also use the new isAction util to check if an unknown value is some kind of action object.

Middleware type changed - Middleware action and next are typed as unknown

Previously, the next parameter is typed as the D type parameter passed, and action is typed as the Action extracted from the dispatch type. Neither of these are a safe assumption:

  • next would be typed to have all of the dispatch extensions, including the ones earlier in the chain that would no longer apply.
    • Technically it would be mostly safe to type next as the default Dispatch implemented by the base redux store, however this would cause next(action) to error (as we cannot promise action is actually an Action) - and it wouldn't account for any following middlewares that return anything other than the action they're given when they see a specific action.
  • action is not necessarily a known action, it can be literally anything - for example a thunk would be a function with no .type property (so AnyAction would be inaccurate)

We've changed next to be (action: unknown) => unknown (which is accurate, we have no idea what next expects or will return), and changed the action parameter to be unknown (which as above, is accurate).

In order to safely interact with values or access fields inside of the action argument, you must first do a type guard check to narrow the type, such as isAction(action) or someActionCreator.match(action).

This new type is incompatible with the v4 Middleware type, so if a package's middleware is saying it's incompatible, check which version of Redux it's getting its types from!

PreloadedState type removed in favour of Reducer generic

We've made tweaks to the TS types to improve type safety and behavior.

First, the Reducer type now has a PreloadedState possible generic:

type Reducer<S, A extends Action, PreloadedState = S> = (
  state: S | PreloadedState | undefined,
  action: A
) => S

Per the explanation in #​4491:

Why the need for this change? When the store is first created by createStore/configureStore, the initial state is set to whatever is passed as the preloadedState argument (or undefined if nothing is passed). That means that the first time that the reducer is called, it is called with the preloadedState. After the first call, the reducer is always passed the current state (which is S).

For most normal reducers, S | undefined accurately describes what can be passed in for the preloadedState. However the combineReducers function allows for a preloaded state of Partial<S> | undefined.

The solution is to have a separate generic that represents what the reducer accepts for its preloaded state. That way createStore can then use that generic for its preloadedState argument.

Previously, this was handled by a $CombinedState type, but that complicated things and led to some user-reported issues. This removes the need for $CombinedState altogether.

This change does include some breaking changes, but overall should not have a huge impact on users upgrading in user-land:

  • The Reducer, ReducersMapObject, and createStore/configureStore types/function take an additional PreloadedState generic which defaults to S.
  • The overloads for combineReducers are removed in favor of a single function definition that takes the ReducersMapObject as its generic parameter. Removing the overloads was necessary with these changes, since sometimes it was choosing the wrong overload.
  • Enhancers that explicitly list the generics for the reducer will need to add the third generic.
Other Changes
Internal Listener Implementation

The Redux store has always used an array to track listener callbacks, and used listeners.findIndex to remove listeners on unsubscribe. As we found in React-Redux, that can have perf issues when many listeners are unsubscribing at once.

In React-Redux, we fixed that with a more sophisticated linked list approach. Here, we've updated the listeners to be stored in a Map instead, which has better delete performance than an array.

In practice this shouldn't have any real effect, because React-Redux sets up a subscription in <Provider>, and all nested components subscribe to that. But, nice to fix it here as well.

isAction Predicate

We recently added an isAction predicate to RTK, then realized it's better suited for the Redux core. This can be used anywhere you have a value that could be a Redux action object, and you need to check if it is actually an action. This is specifically useful for use with the updated Redux middleware TS types, where the default value is now unknown and you need to use a type guard to tell TS that the current value is actually an action:

We've also exported the isPlainObject util that's been in the Redux codebase for years as well.

What's Changed

Entirely too many PRs to list here, as it's been a few years since 4.2 was released :) See the diff below.

Changelog

Named Exports Instead of Default Exports

The redux-thunk package previously used a single default export that was the thunk middleware, with an attached field named withExtraArgument that allowed customization.

The default export has been removed. There are now two named exports: thunk (the basic middleware) and withExtraArgument.

If you are using Redux Toolkit, this should have no effect, as RTK already handles this inside of configureStore.

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/redux-thunk.mjs. Most build tools should pick this up. There's also a CJS artifact, and a second copy of the ESM file named redux-thunk.legacy-esm.js to support Webpack 4 (which does not recognize the exports field in package.json).

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.

The repo has been updated to use Yarn 3 for dependencies and Vitest for running tests.

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.

For now, we're dropping those build artifacts from the published package, on the grounds that the use cases seem pretty rare today.

Since the code is so simple, the ESM artifact can be used directly in the browser via Unpkg.

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

extend-redux Typedefs Removed

Redux Thunk 2.x included a redux-thunk/extend-redux TS-only entry point, which extended the types of dispatch and bindActionCreators to globally give them knowledge of the thunk types. We feel that global overrides from a library are an anti-pattern, and we've removed this entry point. (Note: this ended up being released in 3.1.0, as it was missed in the original 3.0.0 release.)

Please follow our TS setup guidelines to infer the correct type of dispatch for your store.
