React-Query on post methods

[pooryak]

All of apis that backend provided me are post methods. I read that useQuery provides caching functionality. Can i use caching in react-query despite my apis post methods?

[TkDodo]

yes, you can. react-query only cares about the promises returned from the queryFn. with POST requests, you can't do caching on network level in the browser, but that's a different topic :)

[pooryak]

Would you please introduce me to an example that provides caching in POST requests?

[TkDodo]

I don't follow. it doesn't matter:

useQuery('key', () => doThePostRequest())

result of the post request will be cached under key ...

[pooryak]

I need to pass a object through body of POST request.
useQuery('key', (user) => { ApiWalletCurrentRepository.apiWalletCurrentPost(user) });
when I use useQuery I can not pass the object
when I take log from user argument it's not what I passed

[TkDodo]

well where is user coming from? it is definitely not the first argument to the queryFn as you've shown above. If you have a custom hook, you can pass it there:

const useApiWallet = (user) => useQuery(['key', user], () => ApiWalletCurrentRepository.apiWalletCurrentPost(user));

also, all dependencies should go into the query key (I've already done that in the above snippet).

for anything else, please post a codesandbox reproduction.

Yes! While useQuery in React-Query is primarily designed for GET requests, you can still cache POST request responses by using the queryClient to manually set or update the cache after a mutation. This way, you can benefit from caching even when working with POST APIs.

Great point about caching being independent of the request method. Having clear, reliable behavior makes systems easier to trust just like in real-life situations where people rely on dependable services, such as bail bonds Tampa, to guide them quickly and clearly through a stressful process. Straightforward solutions always matter.
