v1.9.4

This bugfix release includes tweaks to RTKQ options handling, tweaks for perf updates, dependency updates, and updates to our CI tooling.

Also, please check out our ongoing RTK 2.0 alpha releases! They have significant improvements to bundle size, ESM/CJS compatibility, TS typings, and reducer update performance. We're looking for real-world feedback on behavior, performance, and any issues you might run into.

Changelog

RTK Query Options Updates

Passing transformResponse as part of enhanceEndpoints can now override the TS type of the original data.

fetchBaseQuery now properly checks for a global responseHandler option.

Performance and Internals

RTK Query now uses Immer's original() to do comparisons inside of copyWithStructuralSharing, which should significantly speed up performance when applying changes from re-fetched data.

RTKQ's internal subscriptionUpdated action is now marked as batchable.

We've updated dependencies to Immer 9.0.21, Reselect 4.1.8, and Redux 4.2.1.

CI Updates

We've added a suite of example apps built with different frameworks such as CRA 4, CRA 5, Next, and Vite, as well as examples that check for compatibility in Node with CJS and ESM modes and with various TS module resolution modes.
