Bumps react-redux from 7.2.4 to 8.1.1.

Release notes

v8.1.1

This bugfix release tweaks the recent lazy context setup logic to ensure a single React context instance per React version, and removes the recently added RTK peerdep to fix an issue with Yarn workspaces.

Changelog

React Context Singletons

React Context has always relied on reference identity. If you have two different copies of React or a library in a page, that can cause multiple versions of a context instance to be created, leading to problems like the infamous "Could not find react-redux context" error.

In v8.1.0, we reworked the internals to lazily create our single ReactReduxContext instance to avoid issues in a React Server Components environment.

This release further tweaks that to stash a single context instance per React version found in the page, thus hopefully avoiding the "multiple copies of the same context" error in the future.

What's Changed

fix: fix typescript error on non exported type by @luzzif in reduxjs/react-redux#2034

create singleton context by React version by @phryneas in reduxjs/react-redux#2039

remove RTK peerDep by @markerikson in 44fc725

Full Changelog: reduxjs/react-redux@v8.1.0...v8.1.1

v8.1.0

This feature release adds new development-mode safety checks for common errors (like poorly-written selectors), adds a workaround to fix crash errors when React-Redux hooks are imported into React Server Component files, and updates our hooks API docs page with improved explanations and updated links.

Changelog

Development Mode Checks for useSelector

We've had a number of users tell us over time that it's common to accidentally write selectors that have bad behavior and cause performance issues. 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:
// Example: globally configure the root state "noop" check to run every time
<Provider store={store} noopCheck="always">
  {children}
</Provider>
// Example: configure `useSelector` to specifically run the reference checks differently:
function Component() {
  // Disable check entirely for this selector
</tr></table>
