Handling API Errors in Redux Toolkit Thunks
In Redux Toolkit, you can handle API errors inside a thunk by using try/catch blocks within the async function of createAsyncThunk. The createAsyncThunk function automatically catches errors thrown inside the payload creator and dispatches a rejected action, allowing you to handle them in the slice’s extraReducers.
1. Use try/catch Inside Thunk: Wrap your async API logic in a try/catch block to catch errors.
2. Throw or return rejectWithValue: Use rejectWithValue to return a custom error payload to reducers.
3. Handle Rejected Case in Slice: In extraReducers, handle the rejected state to update error messages or status.
By using rejectWithValue, you can return meaningful error messages and handle them gracefully in the reducer. This approach ensures better error management and cleaner async logic in Redux Toolkit.
