Release Notes

reduxjs/react-redux (react-redux)

v7.2.9

Compare Source

This patch release updates the rarely-used areStatesEqual option for connect to now pass through ownProps for additional use in determining which pieces of state to compare if desired.

The new signature is:

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

What's Changed

• connect: pass ownProps to areStatesEqual by @​jspurlin in #​1952

v7.2.8

Compare Source

This release fixes a bug in the 7.x branch that caused <Provider> to unsubscribe and stop updating completely when used inside of React 18's <StrictMode>. The new "strict effects" behavior double-mounts components, and the subscription needed to be set up inside of a useLayoutEffect instead of a useMemo. This was previously fixed as part of v8 development, and we've backported it.

Note: If you are now using React 18, we strongly recommend using the React-Redux v8 beta instead of v7.x!. v8 has been rewritten internally to work correctly with React 18's Concurrent Rendering capabilities. React-Redux v7 will run and generally work okay with existing code, but may have rendering issues if you start using Concurrent Rendering capabilities in your code.

Now that React 18 is out, we plan to finalize React-Redux v8 and release it live within the next couple weeks. Per an update yesterday in the "v8 roadmap" thread, React-Redux v8 will be updated in the next couple days to ensure support for React 16.8+ as part of the next beta release. We would really appreciate final feedback on using React-Redux v8 beta with React 18 before we publish the final version.

v7.2.7

Compare Source

This release updates React-Redux v7's peer dependencies to accept React 18 as a valid version, only to avoid installation errors caused by NPM's "install all the peer deps and error if they don't match" behavior.

v7.2.6

Just a quick fix for a Yarn install warning. Sorry about the noise!

Changes

• Remove workspaces from our package.json to silence a Yarn warning (@​timdorr)

v7.2.5

Compare Source

This release shrinks the size of our internal Subscription class, and updates useSelector to avoid an unnecessary selector call on mount.

Changes

Subscription Size Refactor

Our internal Subscription implementation has been written as a class ever since it was added in v5. By rewriting it as a closure factory, we were able to shave a few bytes off the final bundle size.

useSelector Mount Optimization

A user noticed that useSelector had never been given an early "bail out if the root state is the same" check to match how connect works. This resulted in a usually-unnecessary second call to the provided selector on mount. We've added that check.

Entry Point Consolidation

We've consolidated the list of exported public APIs into a single file, and both the index.js and alternate-renderers.js entry points now re-export everything from that file. No meaningful change here, just shuffling lines of code around for consistency.

Other Updates

React-Redux v8 and React 18 Development

With the announcement of React 18, we've been working with the React team to plan our migration path to keep React-Redux fully compatible with React's upcoming features.

We've already migrated the React-Redux main development branch to TypeScript, and are prototyping compatibility implementation updates. We'd appreciate any assistance from the community in testing out these changes so that we can ensure React-Redux works great for everyone when React 18 is ready!

Internal Tooling Updates

Our master branch now uses Yarn v2 for package management, is built with TypeScript, and we've made CI updates to test against multiple TS versions.

The 7.x branch has also been updated to use Yarn v2 for consistency.

These only affect contributors to the React-Redux package itself.

Changelog

• Port entry point consolidation from 8.x branch (#​1811 - @​markerikson)
• Update v7 branch to use Yarn v2 and improve CI process (#​1810 - @​markerikson)
• Reduce unnecessary calls to useSelector selector (#​1803 - @​sufian-slack )
• Port Subscription closure implementation from 8.x to 7.x (#​1809 - @​mbelsky)

v7.2.4

Compare Source

This release drops our dependency on the core redux package by inlining bindActionCreators, and tweaks useSelector to ensure that selectors aren't run an extra time while re-rendering.

Changelog

Redux Dependency Removal

React-Redux has always imported the bindActionCreators utility from the core redux package for use in connect. However, that meant that we had to have a peer dependency on redux, and this was the only reason we actually required that redux be installed. This became more annoying with the arrival of Redux Toolkit, which has its own dependency on redux internally, and thus users typically saw peer dependency warnings saying that "redux isn't listed as a dependency in your app".

Code reuse across separate packages is a great thing, but sometimes the right thing to do is duplicate code. So, we've inlined bindActionCreators directly into React-Redux, and we've completely dropped the dependency on Redux. This means that React-Redux will no longer produce a peerDep warning when used with Redux Toolkit, and <Provider> and connect really only need a Redux-store-compatible value to work right.

useSelector Fixes

Users reported that useSelector was re-running selector functions again unnecessarily while rendering after a dispatch. We've tweaked the logic to ensure that doesn't happen.

useSelector also now has checks in development to ensure that selector and equalityFn are functions.

Changes

• Remove wrapActionCreators (#​1709 - @​xty)
• Verify that selector and equalityF of useSelector are functions (#​1706 - @​gshilin)
• Import bindActionCreators from redux (#​1705 - @​timdorr)
• Don't re-run the selector after update (#​1701 - @​timdorr)

v7.2.3

Compare Source

This release improves behavior in useSelector by returning the existing reference if the newly returned selector result passes the equality check, and adds a hard dependency on the @types/react-redux package to ensure TS users always have the typedefs installed.

Changes

useSelector Results Reuse

Issue #​1654 reported that useSelector was returning new references from a selector even if the equality comparison function returned true. This is because the equality check was only ever being performed during the action dispatch process.

We now run the equality comparison against the value calculated by the selector while rendering, and return the existing reference for consistency if the old and new values are considered equal. This should improve some cases where further derived values where being recalculated unnecessarily.

TS Types Now Included

React-Redux has always been written in plain JS, and the typedefs maintained by the community in DefinitelyTyped. We plan on eventually rewriting the library in TypeScript in a future React-Redux v8 release, but until then the types can stay in DT.

However, having to always manually install @types/react-redux is annoying, and some users have gotten confused by that. This release adds a hard dependency on @types/react-redux, so that if you install react-redux, you automatically get the types as well. This should simplify the process for TS users.

Docs Updates

We've made several docs updates recently:

• Renamed "Quick Start" to "Getting Started" and "Static Typing" to "Usage with TypeScript"
• Dropped the docs API versioning setup, as the legacy API version docs pages were rarely viewed and the versioning setup confused docs contributors
• Moved the old "Intro > Basic Tutorial" to "Tutorials > Connect" and marked it as semi-obsolete

We are currently working on a new React-Redux tutorial that will teach the React-Redux hooks as the primary approach, based on the "UI and React" page in the Redux docs "Fundamentals" tutorial.

Changelog

• Automatically install @​types/react-redux as a dependency (#​1699 - @​markerikson )
• Reuse latest selected state on selector re-run (#​1654) (#​1660 - @​otakustay)
• Use useIsomorphicLayoutEffect in Provider for consistency (#​1683 - @​speakingcode )

v7.2.2

Compare Source

This release allows you to use React Redux with React 17 without a warning when installing. That's about it.

Changes

• Upgrade react peer dependency to v17 (#​1647 by @​wachunei)

v7.2.1

Compare Source

This release improves useSelector value display in the React DevTools, fixes a potential race condition, and fixes a couple additional minor issues.

useSelector DevTools Display

The React DevTools normally show custom hooks with their inspected name (such as "Selector" for useSelector), and any calls to core hooks inside. This is not always informative, so React has the useDebugValue hook to allow custom hooks to specify what value should be shown instead.

useSelector now calls useDebugValue to specifically show the current selected value instead of its internal hooks usage.

Bug Fixes

This release has a few different bug fixes:

• A potential race condition when dispatching actions from child components in the commit phase vs selecting data in a parent
• Removed an excess new object creation when forcing a re-render
• Our internal prop name for a forwarded ref is now reactReduxForwardedRef to avoid a rare situation where someone else might be passing down a field named forwardedRef
• Fixed a typo in a useSelector error message

Changes

• Fix error message typo in useSelector ('You must pass a selector...). (@​Pixelwelder - #​1581)
• fix useSelector race condition with memoized selector when dispatching in child components useLayoutEffect as well as cDM/cDU (@​dai-shi - #​1536)
• removed a redundant object creation when using forceUpdate (@​vzaidman - #​1567)
• Rename internal forwardedRef usage (@​dtschust - #​1553)
• Show useSelector result in React DevTools (@​Finesse - #​1530)

v7.2.0

Compare Source

This release fixes two bugs, an algorithmic problem with unsubscribing components and a memory leak with connect. It also has optimizations for production bundle size, and adds a couple small improvements to developer readability while debugging.

Bug Fixes

connect in v7 is implemented using hooks, and the hooks usage captures numerous values from the surrounding scope. We received a PR informing us that the way we were capturing these values would likely result in a copy of the first version of its props being kept alive indefinitely.

This memory leak has been fixed by extracting a custom hook that receives all the necessary values as arguments, so that they're not captured via closure.

We also received a PR letting us know that the unsubscribe logic had a quadratic algorithm in it, as removing a subscriber would use an indexOf(listener) check to remove that callback. If there were a large number of subscribers, that line's runtime would increase rapidly, causing slowdowns.

This algorithm has been replaced with tracking subscribers via a linked list, which drastically improves the runtime of this section of the code even with large numbers of subscribers.

Thanks to @​larrylin28 and @​wurstbonbon for finding these bugs and submitting PRs to fix them!

Bundle Size Improvements

We've made a number of small tweaks to the codebase to improve the ability of bundlers to shake and minimize the final included size in a bundle. The net result is that [email protected] is smaller than 7.1.3, dropping 1.3K min and 0.6K min+gzip. (In fact, it's even smaller than the pre-hooks 7.0.0 when gzipped!)

Thanks to @​Andarist for doing most of the work on this!

Debugging Improvements

The ReactReduxContext instance now has a displayName set, so it should show up in the React DevTools as ReactRedux.Provider.

Also, when an error is caught in useSelector and re-thrown, we now append the original stack trace.

Thanks to @​pieplu and @​r3dm1ke for these!

Changes

• Fix memory leak issue with UseEffect (@​larrylin28 - #​1506)
• Optimize createListenerCollection (@​wurstbonbon - #​1523)

• Remove invariant in favor of doing NODE_ENV checks directly (@​Andarist - #​1472)
• Wrap .propTypes and .displayName assignments with DEV check (@​Andarist - #​1471)
• Add pure annotations to help with DCE (@​timdorr - 5e0c50d)
• Inline this function. (@​timdorr - 58ae5ed)
• Add a displayName on ReactReduxContext (@​pieplu - #​1462)
