SSR RTK Query Caching

[sbue]

Hi all! We use RTK Query to query our API (using createAPI)

I'd love to persist record of what the API state has cached in cookies, so that in SSR I could skip an API request if already in the cache.

I've tried implementing the following way: I created an "apiCookiesCache" with middleware that runs on API actions (executeQuery/fulfilled) and replicates the queries state (not including the response data) into the cookies (using https://www.npmjs.com/package/next-redux-cookie-wrapper).

There's a few problems with this:

• No simple way to intercept a store.dispatch(getPosts.initiate(query)) action and check the apiCookiesCache to see if we already have this cached in the client-side. I wish I could intercept the action, check if the queryKey is in cache, and drop if so. But this dispatch triggers an anonymous function (which I assume makes the request). Seems like the way to prevent the API from happening is hacky: dispatchIfNotCached(dispatch, 'getPosts', query)
