What is the proper method of resetting the API state in RTK Query?

edit

There are two ways to reset the API state in RTK Query:

1. Clearing the entire cache:

If you want to reset the entire cache for all endpoints, you can call api.clearCache() on the RTK Query instance. This will clear all cached data for all queries.

Example:

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query'

export const api = createApi({
  reducerPath: 'api',
  baseQuery: fetchBaseQuery({ baseUrl: 'https://api.example.com' }),
  endpoints: (builder) => ({
    // endpoint definitions
  }),
})

// To clear the cache:
api.clearCache();

1. Resetting individual query states:

If you want to reset the cache for a specific query, you can call the invalidate() method on the query result object. This will mark the query as invalid and refresh the data the next time it is requested.

Example:

import { useQuery } from '@reduxjs/toolkit/query'

const { data, error, isLoading, invalidate } = useQuery('posts', fetchPosts)

// To reset the cache for this query:
invalidate();
