This preview release adds the new "listener" middleware, and updates configureStore's types to better handle type inference from middleware that override dispatch return values.
The full 1.8.0 release will be out shortly (within the next couple days), and this RC is primarily for some final compatibility checking. The final release will have a longer changelog description, with examples.
Changelog
New "Listener" Middleware
We've been working on a new "listener" middleware, which lets you trigger callback functions when specific actions are dispatched or state is changed.
After iterating on the middleware's API in its own temporary package, it's now ready for actual release as part of RTK.
The preview API reference is available at:
https://deploy-preview-2024--redux-starter-kit-docs.netlify.app/api/createListenerMiddleware
configureStore Middleware Type Improvements
Middleware can override the default return value of dispatch. configureStore tries to extract any declared dispatch type overrides from the middleware array, and uses that to alter the type of store.dispatch.
We identified some cases where the type inference wasn't working well enough, and rewrote the type behavior to be more correct.
TypeScript Support Matrix Updates
RTK now requires TS 4.1 or greater to work correctly, and we've dropped 4.0 and earlier from our support matrix.
