The most common causes of this are either selectors that unconditionally return a new reference (such as `state => state.todos.map()` without any memoization ), or selectors that actually return the *entire* root state ( `state => state` ). We've updated `useSelector` to add safety checks in development mode that warn if these incorrect behaviors are detected: - Selectors will be called twice with the same inputs, and `useSelector` will warn if the results are different references - `useSelector` will warn if the selector result is actually the entire root `state` By default, **these checks only run *once* the first time `useSelector` is called**. This should provide a good balance between detecting possible issues, and keeping development mode execution performant without adding many unnecessary extra selector calls. If you want, you can configure this behavior globally by passing the enum flags directly to `<Provider>`, or on a per-`useSelector` basis by passing an options object as the second argument: ```ts // Example: globally configure the root state "noop" check to run every time <Provider store={store} noopCheck="always"> {children} </Provider> ``` ```ts // Example: configure `useSelector` to specifically run the reference checks differently: function Component() { // Disable check entirely for this selector const count = useSelector(selectCount, { stabilityCheck: 'never' }) // run once (default) const user = useSelector(selectUser, { stabilityCheck: 'once' }) // ... } ``` This goes along with the similar safety checks we've added to [Reselect v5 alpha](https://togithub.com/reduxjs/reselect/releases/tag/v5.0.0-alpha.2) as well. ##### Context Changes We're still trying to work out how to properly use Redux and React Server Components together. One possibility is using RTK Query's `createApi` to define data fetching endpoints, and using the generated thunks to fetch data in RSCs, but it's still an open question. However, users have reported that merely importing *any* React-Redux API in an RSC file causes a crash, because `React.createContext` is not defined in RSC files. RTKQ's React-specific `createApi` entry point imports React-Redux, so it's been unusable in RSCs. This release adds a workaround to fix that issue, by using a proxy wrapper around our singleton `ReactReduxContext` instance and lazily creating that instance on demand. In testing, this appears to both continue to work in all unit tests, *and* fixes the import error in an RSC environment. We'd appreciate further feedback in case this change does cause any issues for anyone! We've also tweaked the internals of the hooks to do checks for correct `<Provider>` usage when using a custom context, same as the default context checks. ##### Docs Updates We've cleaned up some of the Hooks API reference page, and updated links to the React docs. #### What's Changed - check for Provider even when using custom context by [@​EskiMojo14](https://togithub.com/EskiMojo14) in [https://github.com/reduxjs/react-redux/pull/1990](https://togithub.com/reduxjs/react-redux/pull/1990) - Add a stability check, to see if selector returns stable result when called with same parameters. by [@​EskiMojo14](https://togithub.com/EskiMojo14) in [https://github.com/reduxjs/react-redux/pull/2000](https://togithub.com/reduxjs/react-redux/pull/2000) - Add an E2E-ish test that verifies behavior when imported into RSCs by [@​markerikson](https://togithub.com/markerikson) in [https://github.com/reduxjs/react-redux/pull/2030](https://togithub.com/reduxjs/react-redux/pull/2030) - lazily create Context for RSC compat by [@​phryneas](https://togithub.com/phryneas) in [https://github.com/reduxjs/react-redux/pull/2025](https://togithub.com/reduxjs/react-redux/pull/2025) - Add warning for selectors that return the entire state by [@​EskiMojo14](https://togithub.com/EskiMojo14) in [https://github.com/reduxjs/react-redux/pull/2022](https://togithub.com/reduxjs/react-redux/pull/2022) **Full Changelog**: reduxjs/react-redux@v8.0.7...v8.1.0 ### [`v8.0.7`](https://togithub.com/reduxjs/react-redux/releases/tag/v8.0.7) [Compare Source](https://togithub.com/reduxjs/react-redux/compare/v8.0.6...v8.0.7) This release updates the peer dependencies to accept Redux Toolkit, and accept the ongoing RTK and Redux core betas as valid peer deps. > **Note**: These changes were initially in 8.0.6, but that had a typo in the peer deps that broke installation.
