Release Notes

reduxjs/redux-toolkit (@​reduxjs/toolkit)

v2.9.2

Compare Source

This bugfix release fixes a potential internal data leak in SSR environments, improves handling of headers in fetchBaseQuery, improves retry handling for unexpected errors and request aborts, and fixes a longstanding issue with prefetch leaving an unused subscription. We've also shipped a new graphqlRequestBaseQuery release with updated dependencies and better error handling.

Changelog

Internal Subscription Handling

We had a report that a Redux SSR app had internal subscription data showing up across different requests. After investigation, this was a bug introduced by the recent RTKQ perf optimizations, where the internal subscription fields were hoisted outside of the middleware setup and into createApi itself. This meant they existed outside of the per-store-instance lifecycle. We've reworked the logic to ensure the data is per-store again. We also fixed another issue that miscalculated when there was an active request while checking for cache entry cleanup.

Note that no actual app data was leaked in this case, just the internal subscription IDs that RTKQ uses in its own middleware to track the existence of subscriptions per cache entry.

fetchBaseQuery Headers

We've updated fetchBaseQuery to avoid setting content-type in cases where a non-JSONifiable value like FormData is being passed as the request body, so that the browser can set that content type itself. It also now sets the accept header based on the selected responseHandler (JSON or text).

retry Behavior and Cleanup

The retry util now respects the maxRetries option when catching unknown errors in addition to the existing known errors logic. It also now checks the request's AbortSignal and will stop retrying if aborted.

In conjunction with that, dispatching resetApiState will now abort all in-flight requests.

The prefetch util and usePrefetch hook had a long-standing issue where they would create a subscription for a cache entry, but there was no way to clean up that subscription. This meant that the cache entry was effectively permanent. They now initiate the request without adding a subscription. This will fetch the cache entry and leave it in the store for the keepUnusedDataFor period as intended, giving your app time to actually subscribe to the value (such as prefetching the cache entry in a route handler, and then subscribing in a component).

graphqlRequestBaseQuery

We've published @rtk-query/graphql-request-base-query v2.3.2, which updates the graphql-request dep to ^7. We also fixed an issue where the error handling rethrew unknown errors - it now returns {error} as a base query is supposed to.
