CI failure on this is unrelated - codegen tests have been failing since node-fetch was bumped (ESM vs CJS issues, it seems)

@aryaemami59 is working on converting codegen tests to vitest which should hopefully help with this but in the meantime i think this can be merged

Adds a second parameter to `entityAdapter.getInitialState(additionalProps, entities)` to allow prefilling state - Equivalent to `entityAdapter.setAll(entityAdapter.getInitialState(additionalProps), entities)` - First parameter can be `undefined` if no additional properties are desired - Allows initialising `combineSlices` with no static reducers - Previously `const combinedReducer = combineSlices().withLazyLoadedSlices<LazyLoadedSlices>()` would have thrown an error - Now returns a "no-op" reducer that just returns an empty object until first reducer injected - Allows a new `'throw'` value for `overrideExisting` in `injectEndpoints`, which throws an error if a definition is injected with a name which is already used - Exports more type helpers for RTKQ hook and trigger types - Exports types related to overriding result types in `enhanceEndpoints` - Fixes state inference for injected slices when undeclared (i.e. not in `LazyLoadedSlices`) - Adds a `action.meta.arg.isPrefetch` value to query thunk actions when prefetched #### What's Changed - Revamp type tests setup by [@aryaemami59](https://github.com/aryaemami59) in [https://github.com/reduxjs/redux-toolkit/pull/4095](https://github.com/reduxjs/redux-toolkit/pull/4095) -

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](https://redux.js.org/usage/migrations/migrating-rtk-2)** 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!**](https://redux.js.org/usage/migrating-to-modern-redux)) ```bash ##### RTK npm install @reduxjs/toolkit yarn add @reduxjs/toolkit ``` ##### Changelog ##### Object syntax for `createSlice.extraReducers` and `createReducer` removed RTK's `createReducer` API was originally designed to accept a lookup table of action type strings to case reducers, like `{ "ADD_TODO": (state, action) => {} }`. We later added the "builder callback" form to allow more flexibility in adding "matchers" and a default handler, and did the same for `createSlice.extraReducers`. We have removed the "object" form for both `createReducer` and `createSlice.extraReducers` in RTK 2.0, as the builder callback form is effectively the same number of lines of code, and works much better with TypeScript. As an example, this: ```ts const todoAdded = createAction('todos/todoAdded') createReducer(initialState, { [todoAdded]: (state, action) => {}, }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: { [todoAdded]: (state, action) => {}, }, }) ``` should be migrated to: ```ts createReducer(initialState, (builder) => { builder.addCase(todoAdded, (state, action) => {}) }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: (builder) => { builder.addCase(todoAdded, (state, action) => {}) }, }) ``` ##### Codemods To simplify upgrading codebases, we've published a set of codemods that will automatically transform the deprecated "object" syntax into the equivalent "builder" syntax. The codemods package is available on NPM as [`@reduxjs/rtk-codemods`](https://www.npmjs.com/package/@reduxjs/rtk-codemods). More details are available [here](../api/codemods). To run the codemods against your codebase, run `npx @reduxjs/rtk-codemods <TRANSFORM NAME> path/of/files/ or/some**/*glob.js.` Examples: ```sh npx @reduxjs/rtk-codemods createReducerBuilder ./src npx @reduxjs/rtk-codemods createSliceBuilder ./packages/my-app/**/*.ts ``` We also recommend re-running Prettier on the codebase before committing the changes. These codemods should work, but we would greatly appreciate feedback from more real-world codebases! ##### `configureStore` Options Changes ##### `configureStore.middleware` must be a callback Since the beginning, `configureStore` has accepted a direct array value as the `middleware` option. However, providing an array directly prevents `configureStore` from calling `getDefaultMiddleware()`. So, `middleware: [myMiddleware]` means there is no thunk middleware added (or any of the dev-mode checks). This is a footgun, and we've had numerous users accidentally do this and cause their apps to fail because the default middleware never got configured. As a result, we've now made the `middleware` only accept the callback form. *If* for some reason you still want to replace *all* of the built-in middleware, do so by returning an array from the callback: ```ts const store = configureStore({ reducer, middleware: (getDefaultMiddleware) => { // WARNING: this means that _none_ of the default middleware are added! return [myMiddleware] // or for TS users, use: // return new Tuple(myMiddleware) }, }) ``` But note that **we consistently recommend not replacing the default middleware entirely**, and that you should use `return getDefaultMiddleware().concat(myMiddleware)`. ##### `configureStore.enhancers` must be a callback Similarly to `configureStore.middleware`, the `enhancers` field must also be a callback, for the same reasons. The callback will receive a `getDefaultEnhancers` function that can be used to customise the batching enhancer [that's now included by default](#configurestore-adds-autobatchenhancer-by-default). For example: ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return getDefaultEnhancers({ autoBatch: { type: 'tick' }, }).concat(myEnhancer) }, }) ``` It's important to note that the result of `getDefaultEnhancers` will **also** contain the middleware enhancer created with any configured/default middleware. To help prevent mistakes, `configureStore` will log an error to console if middleware was provided and the middleware enhancer wasn't included in the callback result. ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return [myEnhancer] // we've lost the middleware here // instead: return getDefaultEnhancers().concat(myEnhancer) }, }) ``` Also, note that **if you supply the `enhancers` field, it *must* come *after* the `middleware` field in order for TS inference to work properly**. ##### Standalone `getDefaultMiddleware` and `getType` removed The standalone version of `getDefaultMiddleware` has been deprecated since v1.6.1, and has now been removed. Use the function passed to the `middleware` callback instead, which has the correct types. We have also removed the `getType` export, which was used to extract a type string from action creators made with `createAction`. Instead, use the static property `actionCreator.type`. ##### RTK Query behaviour changes We've had a number of reports where RTK Query had issues around usage of `dispatch(endpoint.initiate(arg, {subscription: false}))`. There were also reports that multiple triggered lazy queries were resolving the promises at the wrong time. Both of these had the same underlying issue, which was that RTKQ wasn't tracking cache entries in these cases (intentionally). We've reworked the logic to always track cache entries (and remove them as needed), which should resolve those behavior issues. We also have had issues raised about trying to run multiple mutations in a row and how tag invalidation behaves. RTKQ now has internal logic to delay tag invalidation briefly, to allow multiple invalidations to get handled together. This is controlled by a new `invalidationBehavior: 'immediate' | 'delayed'` flag on `createApi`. The new default behavior is `'delayed'`. Set it to `'immediate'` to revert to the behavior in RTK 1.9. In RTK 1.9, we reworked RTK Query's internals to keep most of the subscription status inside the RTKQ middleware. The values are still synced to the Redux store state, but this is primarily for display by the Redux DevTools "RTK Query" panel. Related to the cache entry changes above, we've optimized how often those values get synced to the Redux state for perf. ##### 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-toolkit.modern.mjs`**. Most build tools should pick this up. There's also a CJS artifact, and a second copy of the ESM file named `redux-toolkit.legacy-esm.js` to support Webpack 4 (which does not recognize the `exports` field in `package.json`). Additionally, all of the build artifacts now live under `./dist/` in the published package. ##### 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 `redux-toolkit.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! ##### Dependency Updates ##### Redux Libraries RTK now depends on **[Redux core 5.0](https://github.com/reduxjs/redux/releases/tag/v5.0.0), [Reselect 5.0](https://github.com/reduxjs/reselect/releases/tag/v5.0.0), and [Redux Thunk 3.0](https://github.com/reduxjs/redux-thunk/releases/tag/v3.0.0)**. See the linked release notes for those libraries, as **each of them has additional breaking changes**. The ["Migrating to RTK 2.0 and Redux 5.0" docs page](https://redux.js.org/usage/migrations/migrating-rtk-2) also covers the combined changes in one page ##### Immer 10 RTK now also depends on [Immer 10.0](https://github.com/immerjs/immer/releases/tag/v10.0.0), which has several major improvements and updates: - Much faster update perf - Much smaller bundle size - Better ESM/CJS package formatting - No default export - No ES5 fallback We've also removed the prior call to automatically enable the Immer ES5 fallback mode any time RTK was loaded. ##### Other Changes ##### Bundle Size Optimizations Redux 4.1.0 optimized its bundle size by [extracting error message strings out of production builds](https://github.com/reduxjs/redux/releases/tag/v4.1.0), based on React's approach. We've applied the same technique to RTK. This saves about 1000 bytes from prod bundles (actual benefits will depend on which imports are being used). We also noted that [ESBuild does not deduplicate imports when it bundles source files](https://github.com/evanw/esbuild/issues/475), and this was causing RTK Query's bundle to contain a dozen references to `import { } from "@reduxjs/toolkit"`, including some of the same methods. Manually deduplicating those saves about 600 bytes off the production RTKQ artifact. ##### `reactHooksModule` custom hook configuration Previously, custom versions of React Redux's hooks (`useSelector`, `useDispatch`, and `useStore`) could be passed separately to `reactHooksModule`, usually to enable using a different context to the default `ReactReduxContext`. In practicality, the react hooks module needs all three of these hooks to be provided, and it became an easy mistake to only pass `useSelector` and `useDispatch`, without `useStore`. The module has now moved all three of these under the same configuration key, and will check that all three are provided if the key is present. ```ts // previously const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }) ) // now const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ hooks: { useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }, }) ) ``` ##### Deprecated Options Removed Several other options were previously marked as deprecated, and have been removed. We've also removed polyfills like the `AbortController` polyfill. ##### TypeScript Changes ##### `configureStore` field order for `middleware` matters If you are passing *both* the `middleware` and `enhancers` fields to `configureStore`, the `middleware` field *must* come first in order for internal TS inference to work properly. ##### Non-default middleware/enhancers must use `Tuple` We've seen many cases where users passing the `middleware` parameter to configureStore have tried spreading the array returned by `getDefaultMiddleware()`, or passed an alternate plain array. This unfortunately loses the exact TS types from the individual middleware, and often causes TS problems down the road (such as `dispatch` being typed as `Dispatch<AnyAction>` and not knowing about thunks). `getDefaultMiddleware()` already used an internal `MiddlewareArray` class, an `Array` subclass that had strongly typed `.concat/prepend()` methods to correctly capture and retain the middleware types. We've renamed that type to `Tuple`, and `configureStore`'s TS types now require that you *must* use `Tuple` if you want to pass your own array of middleware: ```ts import { configureStore, Tuple } from '@reduxjs/toolkit' configureStore({ reducer: rootReducer, middleware: (getDefaultMiddleware) => new Tuple(additionalMiddleware, logger), }) ``` (Note that this has no effect if you're using RTK with plain JS, and you could still pass a plain array here.) This same restriction applies to the `enhancers` field. ##### Entity adapter type updates `createEntityAdapter` now has an `Id` generic argument, which will be used to strongly type the item IDs anywhere those are exposed. Previously, the ID field type was always `string | number`. TS will now try to infer the exact type from either the `.id` field of your entity type, or the `selectId` return type. You could also fall back to passing that generic type directly. **If you use the `EntityState<Data, Id>` type directly, you *must* supply both generic arguments!** The `.entities` lookup table is now defined to use a standard TS `Record<Id, MyEntityType>`, which assumes that each item lookup exists by default. Previously, it used a `Dictionary<MyEntityType>` type, which assumed the result was `MyEntityType | undefined`. The `Dictionary` type has been removed. If you prefer to assume that the lookups *might* be undefined, use TypeScript's `noUncheckedIndexedAccess` configuration option to control that. ##### New Features These features are new in Redux Toolkit 2.0, and help cover additional use cases that we've seen users ask for in the ecosystem. ##### `combineSlices` API with slice reducer injection for code-splitting The Redux core has always included `combineReducers`, which takes an object full of "slice reducer" functions and generates a reducer that calls those slice reducers. RTK's `createSlice` generates slice reducers + associated action creators, and we've taught the pattern of exporting individual action creators as named exports and the slice reducer as a default export. Meanwhile, we've never had official support for lazy-loading reducers, although we've had [sample code for some "reducer injection" patterns in our docs](https://redux.js.org/usage/code-splitting). This release includes a new [`combineSlices`](../api/combineSlices) API that is designed to enable lazy-loading of reducers at runtime. It accepts individual slices or an object full of slices as arguments, and automatically calls `combineReducers` using the `sliceObject.name` field as the key for each state field. The generated reducer function has an additional `.inject()` method attached that can be used to dynamically inject additional slices at runtime. It also includes a `.withLazyLoadedSlices()` method that can be used to generate TS types for reducers that will be added later. See [#2776](https://github.com/reduxjs/redux-toolkit/issues/2776) for the original discussion around this idea. For now, we are not building this into `configureStore`, so you'll need to call `const rootReducer = combineSlices(.....)` yourself and pass that to `configureStore({reducer: rootReducer})`. **Basic usage: a mixture of slices and standalone reducers passed to `combineSlices`** ```ts const stringSlice = createSlice({ name: 'string', initialState: '', reducers: {}, }) const numberSlice = createSlice({ name: 'number', initialState: 0, reducers: {}, }) const booleanReducer = createReducer(false, () => {}) const api = createApi(/* */) const combinedReducer = combineSlices( stringSlice, { num: numberSlice.reducer, boolean: booleanReducer, }, api ) expect(combinedReducer(undefined, dummyAction())).toEqual({ string: stringSlice.getInitialState(), num: numberSlice.getInitialState(), boolean: booleanReducer.getInitialState(), api: api.reducer.getInitialState(), }) ``` **Basic slice reducer injection** ```ts // Create a reducer with a TS type that knows `numberSlice` will be injected const combinedReducer = combineSlices(stringSlice).withLazyLoadedSlices< WithSlice<typeof numberSlice> >() // `state.number` doesn't exist initially expect(combinedReducer(undefined, dummyAction()).number).toBe(undefined) // Create a version of the reducer with `numberSlice` injected (mainly useful for types) const injectedReducer = combinedReducer.inject(numberSlice) // `state.number` now exists, and injectedReducer's type no longer marks it as optional expect(injectedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) // original reducer has also been changed (type is still optional) expect(combinedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) ``` ##### `selectors` field in `createSlice` The existing `createSlice` API now has support for defining [`selectors`](../api/createSlice#selectors) directly as part of the slice. By default, these will be generated with the assumption that the slice is mounted in the root state using `slice.name` as the field, such as `name: "todos"` -> `rootState.todos`. Additionally, there's now a `slice.selectSlice` method that does that default root state lookup. You can call `sliceObject.getSelectors(selectSliceState)` to generate the selectors with an alternate location, similar to how `entityAdapter.getSelectors()` works. ```ts const slice = createSlice({ name: 'counter', initialState: 42, reducers: {}, selectors: { selectSlice: (state) => state, selectMultiple: (state, multiplier: number) => state * multiplier, }, }) // Basic usage const testState = { [slice.name]: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.selectors expect(selectSlice(testState)).toBe(slice.getInitialState()) expect(selectMultiple(testState, 2)).toBe(slice.getInitialState() * 2) // Usage with the slice reducer mounted under a different key const customState = { number: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.getSelectors( (state: typeof customState) => state.number ) expect(selectSlice(customState)).toBe(slice.getInitialState()) expect(selectMultiple(customState, 2)).toBe(slice.getInitialState() * 2) ``` ##### `createSlice.reducers` callback syntax and thunk support One of the oldest feature requests we've had is the ability to declare thunks directly inside of `createSlice`. Until now, you've always had to declare them separately, give the thunk a string action prefix, and handle the actions via `createSlice.extraReducers`: ```ts // Declare the thunk separately const fetchUserById = createAsyncThunk( 'users/fetchByIdStatus', async (userId: number, thunkAPI) => { const response = await userAPI.fetchById(userId) return response.data } ) const usersSlice = createSlice({ name: 'users', initialState, reducers: { // standard reducer logic, with auto-generated action types per reducer }, extraReducers: (builder) => { // Add reducers for additional action types here, and handle loading state as needed builder.addCase(fetchUserById.fulfilled, (state, action) => { state.entities.push(action.payload) }) }, }) ``` Many users have told us that this separation feels awkward. We've *wanted* to include a way to define thunks directly inside of `createSlice`, and have played around with various prototypes. There were always two major blocking issues, and a secondary concern: 1. It wasn't clear what the syntax for declaring a thunk inside should look like. 2. Thunks have access to `getState` and `dispatch`, but the `RootState` and `AppDispatch` types are normally inferred from the store, which in turn infers it from the slice state types. Declaring thunks inside `createSlice` would cause circular type inference errors, as the store needs the slice types but the slice needs the store types. We weren't willing to ship an API that would work okay for our JS users but not for our TS users, especially since we *want* people to use TS with RTK. 3. You can't do synchronous conditional imports in ES modules, and there's no good way to make the `createAsyncThunk` import optional. Either `createSlice` always depends on it (and adds that to the bundle size), or it can't use `createAsyncThunk` at all. We've settled on these compromises: - **In order to create async thunks with `createSlice`, you specifically need to [set up a custom version of `createSlice` that has access to `createAsyncThunk`](../api/createSlice#createasyncthunk)**. - You can declare thunks inside of `createSlice.reducers`, by using a "creator callback" syntax for the `reducers` field that is similar to the `build` callback syntax in RTK Query's `createApi` (using typed functions to create fields in an object). Doing this does look a bit different than the existing "object" syntax for the `reducers` field, but is still fairly similar. - You can customize *some* of the types for thunks inside of `createSlice`, but you *cannot* customize the `state` or `dispatch` types. If those are needed, you can manually do an `as` cast, like `getState() as RootState`. In practice, we hope these are reasonable tradeoffs. Creating thunks inside of `createSlice` has been widely asked for, so we think it's an API that will see usage. If the TS customization options are a limitation, you can still declare thunks outside of `createSlice` as always, and most async thunks don't need `dispatch` or `getState` - they just fetch data and return. And finally, setting up a custom `createSlice` allows you to opt into `createAsyncThunk` being included in your bundle size (though it may already be included if used directly or as part of RTK Query - in either of these cases there's no *additional* bundle size). Here's what the new callback syntax looks like: ```ts const createSliceWithThunks = buildCreateSlice({ creators: { asyncThunk: asyncThunkCreator }, }) const todosSlice = createSliceWithThunks({ name: 'todos', initialState: { loading: false, todos: [], error: null, } as TodoState, reducers: (create) => ({ // A normal "case reducer", same as always deleteTodo: create.reducer((state, action: PayloadAction<number>) => { state.todos.splice(action.payload, 1) }), // A case reducer with a "prepare callback" to customize the action addTodo: create.preparedReducer( (text: string) => { const id = nanoid() return { payload: { id, text } } }, // action type is inferred from prepare callback (state, action) => { state.todos.push(action.payload) } ), // An async thunk fetchTodo: create.asyncThunk( // Async payload function as the first argument async (id: string, thunkApi) => { const res = await fetch(`myApi/todos?id=${id}`) return (await res.json()) as Item }, // An object containing `{pending?, rejected?, fulfilled?, settled?, options?}` second { pending: (state) => { state.loading = true }, rejected: (state, action) => { state.error = action.payload ?? action.error }, fulfilled: (state, action) => { state.todos.push(action.payload) }, // settled is called for both rejected and fulfilled actions settled: (state, action) => { state.loading = false }, } ), }), }) // `addTodo` and `deleteTodo` are normal action creators. // `fetchTodo` is the async thunk export const { addTodo, deleteTodo, fetchTodo } = todosSlice.actions ``` ##### Codemod **Using the new callback syntax is entirely optional (the object syntax is still standard)**, but an existing slice would need to be converted before it can take advantage of the new capabilities this syntax provides. To make this easier, a [codemod](../api/codemods) is provided. ```sh npx @reduxjs/rtk-codemods createSliceReducerBuilder ./src/features/todos/slice.ts ``` ##### "Dynamic middleware" middleware A Redux store's middleware pipeline is fixed at store creation time and can't be changed later. We *have* seen ecosystem libraries that tried to allow dynamically adding and removing middleware, potentially useful for things like code splitting. This is a relatively niche use case, but we've built [our own version of a "dynamic middleware" middleware](../api/createDynamicMiddleware). Add it to the Redux store at setup time, and it lets you add middleware later at runtime. It also comes with a [React hook integration that will automatically add a middleware to the store and return the updated dispatch method.](../api/createDynamicMiddleware#react-integration). ```ts import { createDynamicMiddleware, configureStore } from '@reduxjs/toolkit' const dynamicMiddleware = createDynamicMiddleware() const store = configureStore({ reducer: { todos: todosReducer, }, middleware: (getDefaultMiddleware) => getDefaultMiddleware().prepend(dynamicMiddleware.middleware), }) // later dynamicMiddleware.addMiddleware(someOtherMiddleware) ``` ##### `configureStore` adds `autoBatchEnhancer` by default [In v1.9.0, we added a new `autoBatchEnhancer`](https://github.com/reduxjs/redux-toolkit/releases/tag/v1.9.0) that delays notifying subscribers briefly when multiple "low-priority" actions are dispatched in a row. This improves perf, as UI updates are typically the most expensive part of the update process. RTK Query marks most of its own internal actions as "low-pri" by default, but you have to have the `autoBatchEnhancer` added to the store to benefit from that. We've updated `configureStore` to add the `autoBatchEnhancer` to the store setup by default, so that users can benefit from the improved perf without needing to manually tweak the store config themselves. ##### `entityAdapter.getSelectors` accepts a `createSelector` function [`entityAdapter.getSelectors()`](../api/createEntityAdapter#selector-functions) now accepts an options object as its second argument. This allows you to pass in your own preferred `createSelector` method, which will be used to memoize the generated selectors. This could be useful if you want to use one of Reselect's new alternate memoizers, or some other memoization library with an equivalent signature. ##### Next.js Setup Guide We now have a docs page that covers [how to set up Redux properly with Next.js](https://redux.js.org/usage/nextjs). We've seen a lot of questions around using Redux, Next, and the App Router together, and this guide should help provide advice. (At this time, the Next.js `with-redux` example is still showing outdated patterns - we're going to file a PR shortly to update that to match our docs guide.) ##### What's Changed - Remove legacy object syntax for reducers by [@markerikson](https://github.com/markerikson) in [https://github.com/reduxjs/redux-toolkit/pull/3051](https://github.com/reduxjs/redux-toolkit/pull/3051) -

Adds a second parameter to `entityAdapter.getInitialState(additionalProps, entities)` to allow prefilling state - Equivalent to `entityAdapter.setAll(entityAdapter.getInitialState(additionalProps), entities)` - First parameter can be `undefined` if no additional properties are desired - Allows initialising `combineSlices` with no static reducers - Previously `const combinedReducer = combineSlices().withLazyLoadedSlices<LazyLoadedSlices>()` would have thrown an error - Now returns a "no-op" reducer that just returns an empty object until first reducer injected - Allows a new `'throw'` value for `overrideExisting` in `injectEndpoints`, which throws an error if a definition is injected with a name which is already used - Exports more type helpers for RTKQ hook and trigger types - Exports types related to overriding result types in `enhanceEndpoints` - Fixes state inference for injected slices when undeclared (i.e. not in `LazyLoadedSlices`) - Adds a `action.meta.arg.isPrefetch` value to query thunk actions when prefetched #### What's Changed - Revamp type tests setup by [@aryaemami59](https://github.com/aryaemami59) in [https://github.com/reduxjs/redux-toolkit/pull/4095](https://github.com/reduxjs/redux-toolkit/pull/4095) -

Removes the deprecated object syntax from `createSlice` and `createReducer` - Removes other deprecated options - Updates the `middleware` and `enhancers` options of `configureStore` to require callbacks - Updates the packaging for better ESM/CJS compatibility and modernizes the build output - Includes all changes to [Redux core 5.0](https://github.com/reduxjs/redux/releases/tag/v5.0.0), [Reselect 5.0](https://github.com/reduxjs/reselect/releases/tag/v5.0.0), and [Redux Thunk 3.0](https://github.com/reduxjs/redux-thunk/releases/tag/v3.0.0) - Updates RTKQ default subscription behavior - Adds a new `combineSlices` method with support for lazy-loading slice reducers - Adds a new "dynamic middleware" middleware with support for adding middleware at runtime - Adds a new callback syntax to `createSlice.reducers`, with optional support for defining thunks inside of `createSlice` - Adds the `autoBatchEnhancer` to `configureStore` by default - Has many additional TS tweaks and improvements This release has **breaking changes**. (Note: v2.0.1 was released with a couple hotfixes for Reselect and Redux Thunk right as this was being finalized.) 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](https://redux.js.org/usage/migrations/migrating-rtk-2)** 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!**](https://redux.js.org/usage/migrating-to-modern-redux)) ```bash ##### RTK npm install @reduxjs/toolkit yarn add @reduxjs/toolkit ``` ##### Changelog ##### Object syntax for `createSlice.extraReducers` and `createReducer` removed RTK's `createReducer` API was originally designed to accept a lookup table of action type strings to case reducers, like `{ "ADD_TODO": (state, action) => {} }`. We later added the "builder callback" form to allow more flexibility in adding "matchers" and a default handler, and did the same for `createSlice.extraReducers`. We have removed the "object" form for both `createReducer` and `createSlice.extraReducers` in RTK 2.0, as the builder callback form is effectively the same number of lines of code, and works much better with TypeScript. As an example, this: ```ts const todoAdded = createAction('todos/todoAdded') createReducer(initialState, { [todoAdded]: (state, action) => {}, }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: { [todoAdded]: (state, action) => {}, }, }) ``` should be migrated to: ```ts createReducer(initialState, (builder) => { builder.addCase(todoAdded, (state, action) => {}) }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: (builder) => { builder.addCase(todoAdded, (state, action) => {}) }, }) ``` ##### Codemods To simplify upgrading codebases, we've published a set of codemods that will automatically transform the deprecated "object" syntax into the equivalent "builder" syntax. The codemods package is available on NPM as [`@reduxjs/rtk-codemods`](https://www.npmjs.com/package/@reduxjs/rtk-codemods). More details are available [here](../api/codemods). To run the codemods against your codebase, run `npx @reduxjs/rtk-codemods <TRANSFORM NAME> path/of/files/ or/some**/*glob.js.` Examples: ```sh npx @reduxjs/rtk-codemods createReducerBuilder ./src npx @reduxjs/rtk-codemods createSliceBuilder ./packages/my-app/**/*.ts ``` We also recommend re-running Prettier on the codebase before committing the changes. These codemods should work, but we would greatly appreciate feedback from more real-world codebases! ##### `configureStore` Options Changes ##### `configureStore.middleware` must be a callback Since the beginning, `configureStore` has accepted a direct array value as the `middleware` option. However, providing an array directly prevents `configureStore` from calling `getDefaultMiddleware()`. So, `middleware: [myMiddleware]` means there is no thunk middleware added (or any of the dev-mode checks). This is a footgun, and we've had numerous users accidentally do this and cause their apps to fail because the default middleware never got configured. As a result, we've now made the `middleware` only accept the callback form. *If* for some reason you still want to replace *all* of the built-in middleware, do so by returning an array from the callback: ```ts const store = configureStore({ reducer, middleware: (getDefaultMiddleware) => { // WARNING: this means that _none_ of the default middleware are added! return [myMiddleware] // or for TS users, use: // return new Tuple(myMiddleware) }, }) ``` But note that **we consistently recommend not replacing the default middleware entirely**, and that you should use `return getDefaultMiddleware().concat(myMiddleware)`. ##### `configureStore.enhancers` must be a callback Similarly to `configureStore.middleware`, the `enhancers` field must also be a callback, for the same reasons. The callback will receive a `getDefaultEnhancers` function that can be used to customise the batching enhancer [that's now included by default](#configurestore-adds-autobatchenhancer-by-default). For example: ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return getDefaultEnhancers({ autoBatch: { type: 'tick' }, }).concat(myEnhancer) }, }) ``` It's important to note that the result of `getDefaultEnhancers` will **also** contain the middleware enhancer created with any configured/default middleware. To help prevent mistakes, `configureStore` will log an error to console if middleware was provided and the middleware enhancer wasn't included in the callback result. ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return [myEnhancer] // we've lost the middleware here // instead: return getDefaultEnhancers().concat(myEnhancer) }, }) ``` Also, note that **if you supply the `enhancers` field, it *must* come *after* the `middleware` field in order for TS inference to work properly**. ##### Standalone `getDefaultMiddleware` and `getType` removed The standalone version of `getDefaultMiddleware` has been deprecated since v1.6.1, and has now been removed. Use the function passed to the `middleware` callback instead, which has the correct types. We have also removed the `getType` export, which was used to extract a type string from action creators made with `createAction`. Instead, use the static property `actionCreator.type`. ##### RTK Query behaviour changes We've had a number of reports where RTK Query had issues around usage of `dispatch(endpoint.initiate(arg, {subscription: false}))`. There were also reports that multiple triggered lazy queries were resolving the promises at the wrong time. Both of these had the same underlying issue, which was that RTKQ wasn't tracking cache entries in these cases (intentionally). We've reworked the logic to always track cache entries (and remove them as needed), which should resolve those behavior issues. We also have had issues raised about trying to run multiple mutations in a row and how tag invalidation behaves. RTKQ now has internal logic to delay tag invalidation briefly, to allow multiple invalidations to get handled together. This is controlled by a new `invalidationBehavior: 'immediate' | 'delayed'` flag on `createApi`. The new default behavior is `'delayed'`. Set it to `'immediate'` to revert to the behavior in RTK 1.9. In RTK 1.9, we reworked RTK Query's internals to keep most of the subscription status inside the RTKQ middleware. The values are still synced to the Redux store state, but this is primarily for display by the Redux DevTools "RTK Query" panel. Related to the cache entry changes above, we've optimized how often those values get synced to the Redux state for perf. ##### 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-toolkit.modern.mjs`**. Most build tools should pick this up. There's also a CJS artifact, and a second copy of the ESM file named `redux-toolkit.legacy-esm.js` to support Webpack 4 (which does not recognize the `exports` field in `package.json`). Additionally, all of the build artifacts now live under `./dist/` in the published package. ##### 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 `redux-toolkit.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! ##### Dependency Updates ##### Redux Libraries RTK now depends on **[Redux core 5.0](https://github.com/reduxjs/redux/releases/tag/v5.0.0), [Reselect 5.0](https://github.com/reduxjs/reselect/releases/tag/v5.0.0), and [Redux Thunk 3.0](https://github.com/reduxjs/redux-thunk/releases/tag/v3.0.0)**. See the linked release notes for those libraries, as **each of them has additional breaking changes**. The ["Migrating to RTK 2.0 and Redux 5.0" docs page](https://redux.js.org/usage/migrations/migrating-rtk-2) also covers the combined changes in one page ##### Immer 10 RTK now also depends on [Immer 10.0](https://github.com/immerjs/immer/releases/tag/v10.0.0), which has several major improvements and updates: - Much faster update perf - Much smaller bundle size - Better ESM/CJS package formatting - No default export - No ES5 fallback We've also removed the prior call to automatically enable the Immer ES5 fallback mode any time RTK was loaded. ##### Other Changes ##### Bundle Size Optimizations Redux 4.1.0 optimized its bundle size by [extracting error message strings out of production builds](https://github.com/reduxjs/redux/releases/tag/v4.1.0), based on React's approach. We've applied the same technique to RTK. This saves about 1000 bytes from prod bundles (actual benefits will depend on which imports are being used). We also noted that [ESBuild does not deduplicate imports when it bundles source files](https://github.com/evanw/esbuild/issues/475), and this was causing RTK Query's bundle to contain a dozen references to `import { } from "@reduxjs/toolkit"`, including some of the same methods. Manually deduplicating those saves about 600 bytes off the production RTKQ artifact. ##### `reactHooksModule` custom hook configuration Previously, custom versions of React Redux's hooks (`useSelector`, `useDispatch`, and `useStore`) could be passed separately to `reactHooksModule`, usually to enable using a different context to the default `ReactReduxContext`. In practicality, the react hooks module needs all three of these hooks to be provided, and it became an easy mistake to only pass `useSelector` and `useDispatch`, without `useStore`. The module has now moved all three of these under the same configuration key, and will check that all three are provided if the key is present. ```ts // previously const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }) ) // now const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ hooks: { useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }, }) ) ``` ##### Deprecated Options Removed Several other options were previously marked as deprecated, and have been removed. We've also removed polyfills like the `AbortController` polyfill. ##### TypeScript Changes ##### `configureStore` field order for `middleware` matters If you are passing *both* the `middleware` and `enhancers` fields to `configureStore`, the `middleware` field *must* come first in order for internal TS inference to work properly. ##### Non-default middleware/enhancers must use `Tuple` We've seen many cases where users passing the `middleware` parameter to configureStore have tried spreading the array returned by `getDefaultMiddleware()`, or passed an alternate plain array. This unfortunately loses the exact TS types from the individual middleware, and often causes TS problems down the road (such as `dispatch` being typed as `Dispatch<AnyAction>` and not knowing about thunks). `getDefaultMiddleware()` already used an internal `MiddlewareArray` class, an `Array` subclass that had strongly typed `.concat/prepend()` methods to correctly capture and retain the middleware types. We've renamed that type to `Tuple`, and `configureStore`'s TS types now require that you *must* use `Tuple` if you want to pass your own array of middleware: ```ts import { configureStore, Tuple } from '@reduxjs/toolkit' configureStore({ reducer: rootReducer, middleware: (getDefaultMiddleware) => new Tuple(additionalMiddleware, logger), }) ``` (Note that this has no effect if you're using RTK with plain JS, and you could still pass a plain array here.) This same restriction applies to the `enhancers` field. ##### Entity adapter type updates `createEntityAdapter` now has an `Id` generic argument, which will be used to strongly type the item IDs anywhere those are exposed. Previously, the ID field type was always `string | number`. TS will now try to infer the exact type from either the `.id` field of your entity type, or the `selectId` return type. You could also fall back to passing that generic type directly. **If you use the `EntityState<Data, Id>` type directly, you *must* supply both generic arguments!** The `.entities` lookup table is now defined to use a standard TS `Record<Id, MyEntityType>`, which assumes that each item lookup exists by default. Previously, it used a `Dictionary<MyEntityType>` type, which assumed the result was `MyEntityType | undefined`. The `Dictionary` type has been removed. If you prefer to assume that the lookups *might* be undefined, use TypeScript's `noUncheckedIndexedAccess` configuration option to control that. ##### New Features These features are new in Redux Toolkit 2.0, and help cover additional use cases that we've seen users ask for in the ecosystem. ##### `combineSlices` API with slice reducer injection for code-splitting The Redux core has always included `combineReducers`, which takes an object full of "slice reducer" functions and generates a reducer that calls those slice reducers. RTK's `createSlice` generates slice reducers + associated action creators, and we've taught the pattern of exporting individual action creators as named exports and the slice reducer as a default export. Meanwhile, we've never had official support for lazy-loading reducers, although we've had [sample code for some "reducer injection" patterns in our docs](https://redux.js.org/usage/code-splitting). This release includes a new [`combineSlices`](../api/combineSlices) API that is designed to enable lazy-loading of reducers at runtime. It accepts individual slices or an object full of slices as arguments, and automatically calls `combineReducers` using the `sliceObject.name` field as the key for each state field. The generated reducer function has an additional `.inject()` method attached that can be used to dynamically inject additional slices at runtime. It also includes a `.withLazyLoadedSlices()` method that can be used to generate TS types for reducers that will be added later. See [#2776](https://github.com/reduxjs/redux-toolkit/issues/2776) for the original discussion around this idea. For now, we are not building this into `configureStore`, so you'll need to call `const rootReducer = combineSlices(.....)` yourself and pass that to `configureStore({reducer: rootReducer})`. **Basic usage: a mixture of slices and standalone reducers passed to `combineSlices`** ```ts const stringSlice = createSlice({ name: 'string', initialState: '', reducers: {}, }) const numberSlice = createSlice({ name: 'number', initialState: 0, reducers: {}, }) const booleanReducer = createReducer(false, () => {}) const api = createApi(/* */) const combinedReducer = combineSlices( stringSlice, { num: numberSlice.reducer, boolean: booleanReducer, }, api ) expect(combinedReducer(undefined, dummyAction())).toEqual({ string: stringSlice.getInitialState(), num: numberSlice.getInitialState(), boolean: booleanReducer.getInitialState(), api: api.reducer.getInitialState(), }) ``` **Basic slice reducer injection** ```ts // Create a reducer with a TS type that knows `numberSlice` will be injected const combinedReducer = combineSlices(stringSlice).withLazyLoadedSlices< WithSlice<typeof numberSlice> >() // `state.number` doesn't exist initially expect(combinedReducer(undefined, dummyAction()).number).toBe(undefined) // Create a version of the reducer with `numberSlice` injected (mainly useful for types) const injectedReducer = combinedReducer.inject(numberSlice) // `state.number` now exists, and injectedReducer's type no longer marks it as optional expect(injectedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) // original reducer has also been changed (type is still optional) expect(combinedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) ``` ##### `selectors` field in `createSlice` The existing `createSlice` API now has support for defining [`selectors`](../api/createSlice#selectors) directly as part of the slice. By default, these will be generated with the assumption that the slice is mounted in the root state using `slice.name` as the field, such as `name: "todos"` -> `rootState.todos`. Additionally, there's now a `slice.selectSlice` method that does that default root state lookup. You can call `sliceObject.getSelectors(selectSliceState)` to generate the selectors with an alternate location, similar to how `entityAdapter.getSelectors()` works. ```ts const slice = createSlice({ name: 'counter', initialState: 42, reducers: {}, selectors: { selectSlice: (state) => state, selectMultiple: (state, multiplier: number) => state * multiplier, }, }) // Basic usage const testState = { [slice.name]: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.selectors expect(selectSlice(testState)).toBe(slice.getInitialState()) expect(selectMultiple(testState, 2)).toBe(slice.getInitialState() * 2) // Usage with the slice reducer mounted under a different key const customState = { number: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.getSelectors( (state: typeof customState) => state.number ) expect(selectSlice(customState)).toBe(slice.getInitialState()) expect(selectMultiple(customState, 2)).toBe(slice.getInitialState() * 2) ``` ##### `createSlice.reducers` callback syntax and thunk support One of the oldest feature requests we've had is the ability to declare thunks directly inside of `createSlice`. Until now, you've always had to declare them separately, give the thunk a string action prefix, and handle the actions via `createSlice.extraReducers`: ```ts // Declare the thunk separately const fetchUserById = createAsyncThunk( 'users/fetchByIdStatus', async (userId: number, thunkAPI) => { const response = await userAPI.fetchById(userId) return response.data } ) const usersSlice = createSlice({ name: 'users', initialState, reducers: { // standard reducer logic, with auto-generated action types per reducer }, extraReducers: (builder) => { // Add reducers for additional action types here, and handle loading state as needed builder.addCase(fetchUserById.fulfilled, (state, action) => { state.entities.push(action.payload) }) }, }) ``` Many users have told us that this separation feels awkward. We've *wanted* to include a way to define thunks directly inside of `createSlice`, and have played around with various prototypes. There were always two major blocking issues, and a secondary concern: 1. It wasn't clear what the syntax for declaring a thunk inside should look like. 2. Thunks have access to `getState` and `dispatch`, but the `RootState` and `AppDispatch` types are normally inferred from the store, which in turn infers it from the slice state types. Declaring thunks inside `createSlice` would cause circular type inference errors, as the store needs the slice types but the slice needs the store types. We weren't willing to ship an API that would work okay for our JS users but not for our TS users, especially since we *want* people to use TS with RTK. 3. You can't do synchronous conditional imports in ES modules, and there's no good way to make the `createAsyncThunk` import optional. Either `createSlice` always depends on it (and adds that to the bundle size), or it can't use `createAsyncThunk` at all. We've settled on these compromises: - **In order to create async thunks with `createSlice`, you specifically need to [set up a custom version of `createSlice` that has access to `createAsyncThunk`](../api/createSlice#createasyncthunk)**. - You can declare thunks inside of `createSlice.reducers`, by using a "creator callback" syntax for the `reducers` field that is similar to the `build` callback syntax in RTK Query's `createApi` (using typed functions to create fields in an object). Doing this does look a bit different than the existing "object" syntax for the `reducers` field, but is still fairly similar. - You can customize *some* of the types for thunks inside of `createSlice`, but you *cannot* customize the `state` or `dispatch` types. If those are needed, you can manually do an `as` cast, like `getState() as RootState`. In practice, we hope these are reasonable tradeoffs. Creating thunks inside of `createSlice` has been widely asked for, so we think it's an API that will see usage. If the TS customization options are a limitation, you can still declare thunks outside of `createSlice` as always, and most async thunks don't need `dispatch` or `getState` - they just fetch data and return. And finally, setting up a custom `createSlice` allows you to opt into `createAsyncThunk` being included in your bundle size (though it may already be included if used directly or as part of RTK Query - in either of these cases there's no *additional* bundle size). Here's what the new callback syntax looks like: ```ts const createSliceWithThunks = buildCreateSlice({ creators: { asyncThunk: asyncThunkCreator }, }) const todosSlice = createSliceWithThunks({ name: 'todos', initialState: { loading: false, todos: [], error: null, } as TodoState, reducers: (create) => ({ // A normal "case reducer", same as always deleteTodo: create.reducer((state, action: PayloadAction<number>) => { state.todos.splice(action.payload, 1) }), // A case reducer with a "prepare callback" to customize the action addTodo: create.preparedReducer( (text: string) => { const id = nanoid() return { payload: { id, text } } }, // action type is inferred from prepare callback (state, action) => { state.todos.push(action.payload) } ), // An async thunk fetchTodo: create.asyncThunk( // Async payload function as the first argument async (id: string, thunkApi) => { const res = await fetch(`myApi/todos?id=${id}`) return (await res.json()) as Item }, // An object containing `{pending?, rejected?, fulfilled?, settled?, options?}` second { pending: (state) => { state.loading = true }, rejected: (state, action) => { state.error = action.payload ?? action.error }, fulfilled: (state, action) => { state.todos.push(action.payload) }, // settled is called for both rejected and fulfilled actions settled: (state, action) => { state.loading = false }, } ), }), }) // `addTodo` and `deleteTodo` are normal action creators. // `fetchTodo` is the async thunk export const { addTodo, deleteTodo, fetchTodo } = todosSlice.actions ``` ##### Codemod **Using the new callback syntax is entirely optional (the object syntax is still standard)**, but an existing slice would need to be converted before it can take advantage of the new capabilities this syntax provides. To make this easier, a [codemod](../api/codemods) is provided. ```sh npx @reduxjs/rtk-codemods createSliceReducerBuilder ./src/features/todos/slice.ts ``` ##### "Dynamic middleware" middleware A Redux store's middleware pipeline is fixed at store creation time and can't be changed later. We *have* seen ecosystem libraries that tried to allow dynamically adding and removing middleware, potentially useful for things like code splitting. This is a relatively niche use case, but we've built [our own version of a "dynamic middleware" middleware](../api/createDynamicMiddleware). Add it to the Redux store at setup time, and it lets you add middleware later at runtime. It also comes with a [React hook integration that will automatically add a middleware to the store and return the updated dispatch method.](../api/createDynamicMiddleware#react-integration). ```ts import { createDynamicMiddleware, configureStore } from '@reduxjs/toolkit' const dynamicMiddleware = createDynamicMiddleware() const store = configureStore({ reducer: { todos: todosReducer, }, middleware: (getDefaultMiddleware) => getDefaultMiddleware().prepend(dynamicMiddleware.middleware), }) // later dynamicMiddleware.addMiddleware(someOtherMiddleware) ``` ##### `configureStore` adds `autoBatchEnhancer` by default [In v1.9.0, we added a new `autoBatchEnhancer`](https://github.com/reduxjs/redux-toolkit/releases/tag/v1.9.0) that delays notifying subscribers briefly when multiple "low-priority" actions are dispatched in a row. This improves perf, as UI updates are typically the most expensive part of the update process. RTK Query marks most of its own internal actions as "low-pri" by default, but you have to have the `autoBatchEnhancer` added to the store to benefit from that. We've updated `configureStore` to add the `autoBatchEnhancer` to the store setup by default, so that users can benefit from the improved perf without needing to manually tweak the store config themselves. ##### `entityAdapter.getSelectors` accepts a `createSelector` function [`entityAdapter.getSelectors()`](../api/createEntityAdapter#selector-functions) now accepts an options object as its second argument. This allows you to pass in your own preferred `createSelector` method, which will be used to memoize the generated selectors. This could be useful if you want to use one of Reselect's new alternate memoizers, or some other memoization library with an equivalent signature. ##### Next.js Setup Guide We now have a docs page that covers [how to set up Redux properly with Next.js](https://redux.js.org/usage/nextjs). We've seen a lot of questions around using Redux, Next, and the App Router together, and this guide should help provide advice. (At this time, the Next.js `with-redux` example is still showing outdated patterns - we're going to file a PR shortly to update that to match our docs guide.) ##### What's Changed - Remove legacy object syntax for reducers by [@markerikson](https://github.com/markerikson) in [https://github.com/reduxjs/redux-toolkit/pull/3051](https://github.com/reduxjs/redux-toolkit/pull/3051) -

Adds a second parameter to `entityAdapter.getInitialState(additionalProps, entities)` to allow prefilling state - Equivalent to `entityAdapter.setAll(entityAdapter.getInitialState(additionalProps), entities)` - First parameter can be `undefined` if no additional properties are desired - Allows initialising `combineSlices` with no static reducers - Previously `const combinedReducer = combineSlices().withLazyLoadedSlices<LazyLoadedSlices>()` would have thrown an error - Now returns a "no-op" reducer that just returns an empty object until first reducer injected - Allows a new `'throw'` value for `overrideExisting` in `injectEndpoints`, which throws an error if a definition is injected with a name which is already used - Exports more type helpers for RTKQ hook and trigger types - Exports types related to overriding result types in `enhanceEndpoints` - Fixes state inference for injected slices when undeclared (i.e. not in `LazyLoadedSlices`) -

Removes the deprecated object syntax from `createSlice` and `createReducer` - Removes other deprecated options - Updates the `middleware` and `enhancers` options of `configureStore` to require callbacks - Updates the packaging for better ESM/CJS compatibility and modernizes the build output - Includes all changes to [Redux core 5.0](https://github.com/reduxjs/redux/releases/tag/v5.0.0), [Reselect 5.0](https://github.com/reduxjs/reselect/releases/tag/v5.0.0), and [Redux Thunk 3.0](https://github.com/reduxjs/redux-thunk/releases/tag/v3.0.0) - Updates RTKQ default subscription behavior - Adds a new `combineSlices` method with support for lazy-loading slice reducers - Adds a new "dynamic middleware" middleware with support for adding middleware at runtime - Adds a new callback syntax to `createSlice.reducers`, with optional support for defining thunks inside of `createSlice` - Adds the `autoBatchEnhancer` to `configureStore` by default - Has many additional TS tweaks and improvements This release has **breaking changes**. (Note: v2.0.1 was released with a couple hotfixes for Reselect and Redux Thunk right as this was being finalized.) 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](https://redux.js.org/usage/migrations/migrating-rtk-2)** 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!**](https://redux.js.org/usage/migrating-to-modern-redux)) ```bash ##### RTK npm install @reduxjs/toolkit yarn add @reduxjs/toolkit ``` ##### Changelog ##### Object syntax for `createSlice.extraReducers` and `createReducer` removed RTK's `createReducer` API was originally designed to accept a lookup table of action type strings to case reducers, like `{ "ADD_TODO": (state, action) => {} }`. We later added the "builder callback" form to allow more flexibility in adding "matchers" and a default handler, and did the same for `createSlice.extraReducers`. We have removed the "object" form for both `createReducer` and `createSlice.extraReducers` in RTK 2.0, as the builder callback form is effectively the same number of lines of code, and works much better with TypeScript. As an example, this: ```ts const todoAdded = createAction('todos/todoAdded') createReducer(initialState, { [todoAdded]: (state, action) => {}, }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: { [todoAdded]: (state, action) => {}, }, }) ``` should be migrated to: ```ts createReducer(initialState, (builder) => { builder.addCase(todoAdded, (state, action) => {}) }) createSlice({ name, initialState, reducers: { /* case reducers here */ }, extraReducers: (builder) => { builder.addCase(todoAdded, (state, action) => {}) }, }) ``` ##### Codemods To simplify upgrading codebases, we've published a set of codemods that will automatically transform the deprecated "object" syntax into the equivalent "builder" syntax. The codemods package is available on NPM as [`@reduxjs/rtk-codemods`](https://www.npmjs.com/package/@reduxjs/rtk-codemods). More details are available [here](../api/codemods). To run the codemods against your codebase, run `npx @reduxjs/rtk-codemods <TRANSFORM NAME> path/of/files/ or/some**/*glob.js.` Examples: ```sh npx @reduxjs/rtk-codemods createReducerBuilder ./src npx @reduxjs/rtk-codemods createSliceBuilder ./packages/my-app/**/*.ts ``` We also recommend re-running Prettier on the codebase before committing the changes. These codemods should work, but we would greatly appreciate feedback from more real-world codebases! ##### `configureStore` Options Changes ##### `configureStore.middleware` must be a callback Since the beginning, `configureStore` has accepted a direct array value as the `middleware` option. However, providing an array directly prevents `configureStore` from calling `getDefaultMiddleware()`. So, `middleware: [myMiddleware]` means there is no thunk middleware added (or any of the dev-mode checks). This is a footgun, and we've had numerous users accidentally do this and cause their apps to fail because the default middleware never got configured. As a result, we've now made the `middleware` only accept the callback form. *If* for some reason you still want to replace *all* of the built-in middleware, do so by returning an array from the callback: ```ts const store = configureStore({ reducer, middleware: (getDefaultMiddleware) => { // WARNING: this means that _none_ of the default middleware are added! return [myMiddleware] // or for TS users, use: // return new Tuple(myMiddleware) }, }) ``` But note that **we consistently recommend not replacing the default middleware entirely**, and that you should use `return getDefaultMiddleware().concat(myMiddleware)`. ##### `configureStore.enhancers` must be a callback Similarly to `configureStore.middleware`, the `enhancers` field must also be a callback, for the same reasons. The callback will receive a `getDefaultEnhancers` function that can be used to customise the batching enhancer [that's now included by default](#configurestore-adds-autobatchenhancer-by-default). For example: ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return getDefaultEnhancers({ autoBatch: { type: 'tick' }, }).concat(myEnhancer) }, }) ``` It's important to note that the result of `getDefaultEnhancers` will **also** contain the middleware enhancer created with any configured/default middleware. To help prevent mistakes, `configureStore` will log an error to console if middleware was provided and the middleware enhancer wasn't included in the callback result. ```ts const store = configureStore({ reducer, enhancers: (getDefaultEnhancers) => { return [myEnhancer] // we've lost the middleware here // instead: return getDefaultEnhancers().concat(myEnhancer) }, }) ``` Also, note that **if you supply the `enhancers` field, it *must* come *after* the `middleware` field in order for TS inference to work properly**. ##### Standalone `getDefaultMiddleware` and `getType` removed The standalone version of `getDefaultMiddleware` has been deprecated since v1.6.1, and has now been removed. Use the function passed to the `middleware` callback instead, which has the correct types. We have also removed the `getType` export, which was used to extract a type string from action creators made with `createAction`. Instead, use the static property `actionCreator.type`. ##### RTK Query behaviour changes We've had a number of reports where RTK Query had issues around usage of `dispatch(endpoint.initiate(arg, {subscription: false}))`. There were also reports that multiple triggered lazy queries were resolving the promises at the wrong time. Both of these had the same underlying issue, which was that RTKQ wasn't tracking cache entries in these cases (intentionally). We've reworked the logic to always track cache entries (and remove them as needed), which should resolve those behavior issues. We also have had issues raised about trying to run multiple mutations in a row and how tag invalidation behaves. RTKQ now has internal logic to delay tag invalidation briefly, to allow multiple invalidations to get handled together. This is controlled by a new `invalidationBehavior: 'immediate' | 'delayed'` flag on `createApi`. The new default behavior is `'delayed'`. Set it to `'immediate'` to revert to the behavior in RTK 1.9. In RTK 1.9, we reworked RTK Query's internals to keep most of the subscription status inside the RTKQ middleware. The values are still synced to the Redux store state, but this is primarily for display by the Redux DevTools "RTK Query" panel. Related to the cache entry changes above, we've optimized how often those values get synced to the Redux state for perf. ##### 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-toolkit.modern.mjs`**. Most build tools should pick this up. There's also a CJS artifact, and a second copy of the ESM file named `redux-toolkit.legacy-esm.js` to support Webpack 4 (which does not recognize the `exports` field in `package.json`). Additionally, all of the build artifacts now live under `./dist/` in the published package. ##### 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 `redux-toolkit.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! ##### Dependency Updates ##### Redux Libraries RTK now depends on **[Redux core 5.0](https://github.com/reduxjs/redux/releases/tag/v5.0.0), [Reselect 5.0](https://github.com/reduxjs/reselect/releases/tag/v5.0.0), and [Redux Thunk 3.0](https://github.com/reduxjs/redux-thunk/releases/tag/v3.0.0)**. See the linked release notes for those libraries, as **each of them has additional breaking changes**. The ["Migrating to RTK 2.0 and Redux 5.0" docs page](https://redux.js.org/usage/migrations/migrating-rtk-2) also covers the combined changes in one page ##### Immer 10 RTK now also depends on [Immer 10.0](https://github.com/immerjs/immer/releases/tag/v10.0.0), which has several major improvements and updates: - Much faster update perf - Much smaller bundle size - Better ESM/CJS package formatting - No default export - No ES5 fallback We've also removed the prior call to automatically enable the Immer ES5 fallback mode any time RTK was loaded. ##### Other Changes ##### Bundle Size Optimizations Redux 4.1.0 optimized its bundle size by [extracting error message strings out of production builds](https://github.com/reduxjs/redux/releases/tag/v4.1.0), based on React's approach. We've applied the same technique to RTK. This saves about 1000 bytes from prod bundles (actual benefits will depend on which imports are being used). We also noted that [ESBuild does not deduplicate imports when it bundles source files](https://github.com/evanw/esbuild/issues/475), and this was causing RTK Query's bundle to contain a dozen references to `import { } from "@reduxjs/toolkit"`, including some of the same methods. Manually deduplicating those saves about 600 bytes off the production RTKQ artifact. ##### `reactHooksModule` custom hook configuration Previously, custom versions of React Redux's hooks (`useSelector`, `useDispatch`, and `useStore`) could be passed separately to `reactHooksModule`, usually to enable using a different context to the default `ReactReduxContext`. In practicality, the react hooks module needs all three of these hooks to be provided, and it became an easy mistake to only pass `useSelector` and `useDispatch`, without `useStore`. The module has now moved all three of these under the same configuration key, and will check that all three are provided if the key is present. ```ts // previously const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }) ) // now const customCreateApi = buildCreateApi( coreModule(), reactHooksModule({ hooks: { useDispatch: createDispatchHook(MyContext), useSelector: createSelectorHook(MyContext), useStore: createStoreHook(MyContext), }, }) ) ``` ##### Deprecated Options Removed Several other options were previously marked as deprecated, and have been removed. We've also removed polyfills like the `AbortController` polyfill. ##### TypeScript Changes ##### `configureStore` field order for `middleware` matters If you are passing *both* the `middleware` and `enhancers` fields to `configureStore`, the `middleware` field *must* come first in order for internal TS inference to work properly. ##### Non-default middleware/enhancers must use `Tuple` We've seen many cases where users passing the `middleware` parameter to configureStore have tried spreading the array returned by `getDefaultMiddleware()`, or passed an alternate plain array. This unfortunately loses the exact TS types from the individual middleware, and often causes TS problems down the road (such as `dispatch` being typed as `Dispatch<AnyAction>` and not knowing about thunks). `getDefaultMiddleware()` already used an internal `MiddlewareArray` class, an `Array` subclass that had strongly typed `.concat/prepend()` methods to correctly capture and retain the middleware types. We've renamed that type to `Tuple`, and `configureStore`'s TS types now require that you *must* use `Tuple` if you want to pass your own array of middleware: ```ts import { configureStore, Tuple } from '@reduxjs/toolkit' configureStore({ reducer: rootReducer, middleware: (getDefaultMiddleware) => new Tuple(additionalMiddleware, logger), }) ``` (Note that this has no effect if you're using RTK with plain JS, and you could still pass a plain array here.) This same restriction applies to the `enhancers` field. ##### Entity adapter type updates `createEntityAdapter` now has an `Id` generic argument, which will be used to strongly type the item IDs anywhere those are exposed. Previously, the ID field type was always `string | number`. TS will now try to infer the exact type from either the `.id` field of your entity type, or the `selectId` return type. You could also fall back to passing that generic type directly. **If you use the `EntityState<Data, Id>` type directly, you *must* supply both generic arguments!** The `.entities` lookup table is now defined to use a standard TS `Record<Id, MyEntityType>`, which assumes that each item lookup exists by default. Previously, it used a `Dictionary<MyEntityType>` type, which assumed the result was `MyEntityType | undefined`. The `Dictionary` type has been removed. If you prefer to assume that the lookups *might* be undefined, use TypeScript's `noUncheckedIndexedAccess` configuration option to control that. ##### New Features These features are new in Redux Toolkit 2.0, and help cover additional use cases that we've seen users ask for in the ecosystem. ##### `combineSlices` API with slice reducer injection for code-splitting The Redux core has always included `combineReducers`, which takes an object full of "slice reducer" functions and generates a reducer that calls those slice reducers. RTK's `createSlice` generates slice reducers + associated action creators, and we've taught the pattern of exporting individual action creators as named exports and the slice reducer as a default export. Meanwhile, we've never had official support for lazy-loading reducers, although we've had [sample code for some "reducer injection" patterns in our docs](https://redux.js.org/usage/code-splitting). This release includes a new [`combineSlices`](../api/combineSlices) API that is designed to enable lazy-loading of reducers at runtime. It accepts individual slices or an object full of slices as arguments, and automatically calls `combineReducers` using the `sliceObject.name` field as the key for each state field. The generated reducer function has an additional `.inject()` method attached that can be used to dynamically inject additional slices at runtime. It also includes a `.withLazyLoadedSlices()` method that can be used to generate TS types for reducers that will be added later. See [#2776](https://github.com/reduxjs/redux-toolkit/issues/2776) for the original discussion around this idea. For now, we are not building this into `configureStore`, so you'll need to call `const rootReducer = combineSlices(.....)` yourself and pass that to `configureStore({reducer: rootReducer})`. **Basic usage: a mixture of slices and standalone reducers passed to `combineSlices`** ```ts const stringSlice = createSlice({ name: 'string', initialState: '', reducers: {}, }) const numberSlice = createSlice({ name: 'number', initialState: 0, reducers: {}, }) const booleanReducer = createReducer(false, () => {}) const api = createApi(/* */) const combinedReducer = combineSlices( stringSlice, { num: numberSlice.reducer, boolean: booleanReducer, }, api ) expect(combinedReducer(undefined, dummyAction())).toEqual({ string: stringSlice.getInitialState(), num: numberSlice.getInitialState(), boolean: booleanReducer.getInitialState(), api: api.reducer.getInitialState(), }) ``` **Basic slice reducer injection** ```ts // Create a reducer with a TS type that knows `numberSlice` will be injected const combinedReducer = combineSlices(stringSlice).withLazyLoadedSlices< WithSlice<typeof numberSlice> >() // `state.number` doesn't exist initially expect(combinedReducer(undefined, dummyAction()).number).toBe(undefined) // Create a version of the reducer with `numberSlice` injected (mainly useful for types) const injectedReducer = combinedReducer.inject(numberSlice) // `state.number` now exists, and injectedReducer's type no longer marks it as optional expect(injectedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) // original reducer has also been changed (type is still optional) expect(combinedReducer(undefined, dummyAction()).number).toBe( numberSlice.getInitialState() ) ``` ##### `selectors` field in `createSlice` The existing `createSlice` API now has support for defining [`selectors`](../api/createSlice#selectors) directly as part of the slice. By default, these will be generated with the assumption that the slice is mounted in the root state using `slice.name` as the field, such as `name: "todos"` -> `rootState.todos`. Additionally, there's now a `slice.selectSlice` method that does that default root state lookup. You can call `sliceObject.getSelectors(selectSliceState)` to generate the selectors with an alternate location, similar to how `entityAdapter.getSelectors()` works. ```ts const slice = createSlice({ name: 'counter', initialState: 42, reducers: {}, selectors: { selectSlice: (state) => state, selectMultiple: (state, multiplier: number) => state * multiplier, }, }) // Basic usage const testState = { [slice.name]: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.selectors expect(selectSlice(testState)).toBe(slice.getInitialState()) expect(selectMultiple(testState, 2)).toBe(slice.getInitialState() * 2) // Usage with the slice reducer mounted under a different key const customState = { number: slice.getInitialState(), } const { selectSlice, selectMultiple } = slice.getSelectors( (state: typeof customState) => state.number ) expect(selectSlice(customState)).toBe(slice.getInitialState()) expect(selectMultiple(customState, 2)).toBe(slice.getInitialState() * 2) ``` ##### `createSlice.reducers` callback syntax and thunk support One of the oldest feature requests we've had is the ability to declare thunks directly inside of `createSlice`. Until now, you've always had to declare them separately, give the thunk a string action prefix, and handle the actions via `createSlice.extraReducers`: ```ts // Declare the thunk separately const fetchUserById = createAsyncThunk( 'users/fetchByIdStatus', async (userId: number, thunkAPI) => { const response = await userAPI.fetchById(userId) return response.data } ) const usersSlice = createSlice({ name: 'users', initialState, reducers: { // standard reducer logic, with auto-generated action types per reducer }, extraReducers: (builder) => { // Add reducers for additional action types here, and handle loading state as needed builder.addCase(fetchUserById.fulfilled, (state, action) => { state.entities.push(action.payload) }) }, }) ``` Many users have told us that this separation feels awkward. We've *wanted* to include a way to define thunks directly inside of `createSlice`, and have played around with various prototypes. There were always two major blocking issues, and a secondary concern: 1. It wasn't clear what the syntax for declaring a thunk inside should look like. 2. Thunks have access to `getState` and `dispatch`, but the `RootState` and `AppDispatch` types are normally inferred from the store, which in turn infers it from the slice state types. Declaring thunks inside `createSlice` would cause circular type inference errors, as the store needs the slice types but the slice needs the store types. We weren't willing to ship an API that would work okay for our JS users but not for our TS users, especially since we *want* people to use TS with RTK. 3. You can't do synchronous conditional imports in ES modules, and there's no good way to make the `createAsyncThunk` import optional. Either `createSlice` always depends on it (and adds that to the bundle size), or it can't use `createAsyncThunk` at all. We've settled on these compromises: - **In order to create async thunks with `createSlice`, you specifically need to [set up a custom version of `createSlice` that has access to `createAsyncThunk`](../api/createSlice#createasyncthunk)**. - You can declare thunks inside of `createSlice.reducers`, by using a "creator callback" syntax for the `reducers` field that is similar to the `build` callback syntax in RTK Query's `createApi` (using typed functions to create fields in an object). Doing this does look a bit different than the existing "object" syntax for the `reducers` field, but is still fairly similar. - You can customize *some* of the types for thunks inside of `createSlice`, but you *cannot* customize the `state` or `dispatch` types. If those are needed, you can manually do an `as` cast, like `getState() as RootState`. In practice, we hope these are reasonable tradeoffs. Creating thunks inside of `createSlice` has been widely asked for, so we think it's an API that will see usage. If the TS customization options are a limitation, you can still declare thunks outside of `createSlice` as always, and most async thunks don't need `dispatch` or `getState` - they just fetch data and return. And finally, setting up a custom `createSlice` allows you to opt into `createAsyncThunk` being included in your bundle size (though it may already be included if used directly or as part of RTK Query - in either of these cases there's no *additional* bundle size). Here's what the new callback syntax looks like: ```ts const createSliceWithThunks = buildCreateSlice({ creators: { asyncThunk: asyncThunkCreator }, }) const todosSlice = createSliceWithThunks({ name: 'todos', initialState: { loading: false, todos: [], error: null, } as TodoState, reducers: (create) => ({ // A normal "case reducer", same as always deleteTodo: create.reducer((state, action: PayloadAction<number>) => { state.todos.splice(action.payload, 1) }), // A case reducer with a "prepare callback" to customize the action addTodo: create.preparedReducer( (text: string) => { const id = nanoid() return { payload: { id, text } } }, // action type is inferred from prepare callback (state, action) => { state.todos.push(action.payload) } ), // An async thunk fetchTodo: create.asyncThunk( // Async payload function as the first argument async (id: string, thunkApi) => { const res = await fetch(`myApi/todos?id=${id}`) return (await res.json()) as Item }, // An object containing `{pending?, rejected?, fulfilled?, settled?, options?}` second { pending: (state) => { state.loading = true }, rejected: (state, action) => { state.error = action.payload ?? action.error }, fulfilled: (state, action) => { state.todos.push(action.payload) }, // settled is called for both rejected and fulfilled actions settled: (state, action) => { state.loading = false }, } ), }), }) // `addTodo` and `deleteTodo` are normal action creators. // `fetchTodo` is the async thunk export const { addTodo, deleteTodo, fetchTodo } = todosSlice.actions ``` ##### Codemod **Using the new callback syntax is entirely optional (the object syntax is still standard)**, but an existing slice would need to be converted before it can take advantage of the new capabilities this syntax provides. To make this easier, a [codemod](../api/codemods) is provided. ```sh npx @reduxjs/rtk-codemods createSliceReducerBuilder ./src/features/todos/slice.ts ``` ##### "Dynamic middleware" middleware A Redux store's middleware pipeline is fixed at store creation time and can't be changed later. We *have* seen ecosystem libraries that tried to allow dynamically adding and removing middleware, potentially useful for things like code splitting. This is a relatively niche use case, but we've built [our own version of a "dynamic middleware" middleware](../api/createDynamicMiddleware). Add it to the Redux store at setup time, and it lets you add middleware later at runtime. It also comes with a [React hook integration that will automatically add a middleware to the store and return the updated dispatch method.](../api/createDynamicMiddleware#react-integration). ```ts import { createDynamicMiddleware, configureStore } from '@reduxjs/toolkit' const dynamicMiddleware = createDynamicMiddleware() const store = configureStore({ reducer: { todos: todosReducer, }, middleware: (getDefaultMiddleware) => getDefaultMiddleware().prepend(dynamicMiddleware.middleware), }) // later dynamicMiddleware.addMiddleware(someOtherMiddleware) ``` ##### `configureStore` adds `autoBatchEnhancer` by default [In v1.9.0, we added a new `autoBatchEnhancer`](https://github.com/reduxjs/redux-toolkit/releases/tag/v1.9.0) that delays notifying subscribers briefly when multiple "low-priority" actions are dispatched in a row. This improves perf, as UI updates are typically the most expensive part of the update process. RTK Query marks most of its own internal actions as "low-pri" by default, but you have to have the `autoBatchEnhancer` added to the store to benefit from that. We've updated `configureStore` to add the `autoBatchEnhancer` to the store setup by default, so that users can benefit from the improved perf without needing to manually tweak the store config themselves. ##### `entityAdapter.getSelectors` accepts a `createSelector` function [`entityAdapter.getSelectors()`](../api/createEntityAdapter#selector-functions) now accepts an options object as its second argument. This allows you to pass in your own preferred `createSelector` method, which will be used to memoize the generated selectors. This could be useful if you want to use one of Reselect's new alternate memoizers, or some other memoization library with an equivalent signature. ##### Next.js Setup Guide We now have a docs page that covers [how to set up Redux properly with Next.js](https://redux.js.org/usage/nextjs). We've seen a lot of questions around using Redux, Next, and the App Router together, and this guide should help provide advice. (At this time, the Next.js `with-redux` example is still showing outdated patterns - we're going to file a PR shortly to update that to match our docs guide.) ##### What's Changed - Remove legacy object syntax for reducers by [@markerikson](https://github.com/markerikson) in [https://github.com/reduxjs/redux-toolkit/pull/3051](https://github.com/reduxjs/redux-toolkit/pull/3051) -
