Renovate Bot requested to merge renovate/react-redux-7.x into master

This MR contains the following updates:

Package Type Update Change
react-redux dependencies patch ^7.2.0 -> 7.2.9

Release Notes

reduxjs/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

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

Compare Source

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

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

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.
