Approach to handle errors in Redux Applications

To handle errors in Redux applications like the provided code, you can follow these steps:

• Use async actions with Redux Thunk or Redux Toolkit’s createAsyncThunk for API requests.
• Handle errors within async action creators using try-catch blocks to catch and manage any exceptions.
• Update the Redux state with error information in the appropriate action type (e.g., fetchTodos.rejected).
• In your React components, conditionally render error messages or UI elements based on the Redux state’s error field to inform users about any errors that occur during data fetching.

To handle errors in Redux applications, use try-catch blocks in your asynchronous action creators to catch errors from API calls or other async operations. Dispatch actions to update the Redux state with error information, which can then be displayed to the user in the UI using components like error modals or notifications. Utilize middleware like Redux Thunk or Redux Saga for more complex error-handling logic.

Syntax of try-catch Block:

export const fetchSomething = () => async (dispatch) => {
  try {
    const response = await axios.get('/api/something');
    dispatch({ type: 'FETCH_SOMETHING_SUCCESS', payload: response.data });
  } catch (error) {
    dispatch({ type: 'FETCH_SOMETHING_FAILURE', payload: error.message });
  }
};
