Release Notes

reduxjs/react-redux

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.

Shameless self-promotion: Check out my new startup, Spaceship 🚀. We're building the Continuous Delivery system of the future.

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)
