What Is Redux Thunk? Redux Thunk is a middleware for Redux that allows you to write action creators that return a function instead of a plain action object. Normally, Redux actions look like this: { type : " SET_USER " , payload : user } Enter fullscreen mode Exit fullscreen mode async code doesn't work directly: Redux would throw an error because it expects an object. dispatch ( async () => { const data = await api . getUser () }) Enter fullscreen mode Exit fullscreen mode But with thunk, you can return a function: const fetchUser = () => { // Return an async function that receives dispatch as parameter return async ( dispatch ) => { const response = await api . getUser () dispatch ({ type : " SET_USER " , payload : response . data }) } } Enter fullscreen mode Exit fullscreen mode Thunk acts as the bridge between async operations and Redux state updates.…
