The Art of Async: Managing State in React

The Art of Async: Managing State in React cover image

Stop putting your API data in Redux. There is a better way to handle loading, caching, and re-fetching.

Server State vs Client State

Important distinction: Client State is ephemeral (is the modal open?). Server State is a cache of remote data (user profile).

Why React Query Wins

React Query handles the hard parts of async: deduplication, background refetching, and cache invalidation. It deletes thousands of lines of boilerplate code.

const { data, isLoading } = useQuery({
  queryKey: ['todos'],
  queryFn: fetchTodos
})

It just works. The UI remains snappy, and data acts "live" without complex WebSocket setups for simple CRUD apps.
