I can try to implement the weather app using redux with typescript but i can get error called Argument of type 'ThunkAction<void, CombinedState<{ weather: WeatherState; alert: AlertState; }>, null, WeatherAction>' is not assignable to parameter of type 'AnyAction'.

I can expect the answer from you.

Please follow the TypeScript QuickStart for Redux and create correctly typed useAppDispatch hooks for your application. The useDispatch hook itself does not know if you have the thunk middleware active and does not take it into account.

CodePudding user response：

These are two distinct problems. Typing in any way will never influence runtime behavior.

Firstly: So your thunk not firing any other action can only have one meaning: The other calls to dispatch are most likely never reached. Are you sure your call to fetch ever terminates? It might just wait forever for an answer or something like that.

Second, your typing issue: the standard Dispatch type does not support thunks by default. Your solution with Dispatch<any> is okay. Otherwise, you could cast your dispatch function to ThunkDispatch from the redux-thunk package.

I advice you to follow this documentation
