Release notes
Package name: react-redux
Just a quick fix for a Yarn install warning. Sorry about the noise!
Changes
workspaces
from our package.json to silence a Yarn warning (@ timdorr)This release shrinks the size of our internal
Subscription
class, and updatesuseSelector
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 OptimizationA user noticed that
useSelector
had never been given an early "bail out if the root state is the same" check to match howconnect
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
andalternate-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...v7.2.5
This release drops our dependency on the core
redux
package by inliningbindActionCreators
, and tweaksuseSelector
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 coreredux
package for use inconnect
. However, that meant that we had to have a peer dependency onredux
, and this was the only reason we actually required thatredux
be installed. This became more annoying with the arrival of Redux Toolkit, which has its own dependency onredux
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>
andconnect
really only need a Redux-store-compatible value to work right.useSelector
FixesUsers 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 thatselector
andequalityFn
are functions.Changes
v7.2.3...v7.2.4
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 ReuseIssue #1654 reported that
useSelector
was returning new references from a selector even if the equality comparison function returnedtrue
. 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 installreact-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:
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
v7.2.2...v7.2.3
This release allows you to use React Redux with React 17 without a warning when installing. That's about it.
Changes
This release improves
useSelector
value display in the React DevTools, fixes a potential race condition, and fixes a couple additional minor issues.useSelector
DevTools DisplayThe 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 theuseDebugValue
hook to allow custom hooks to specify what value should be shown instead.useSelector
now callsuseDebugValue
to specifically show the current selected value instead of its internal hooks usage.Bug Fixes
This release has a few different bug fixes:
reactReduxForwardedRef
to avoid a rare situation where someone else might be passing down a field namedforwardedRef
