Steps to Create a React App and Installing Modules

Step 1: Create a new react app and enter into it by running the following commands

npx create-react-app redux-error-handling

Step 2: After creating your project folder i.e. foldername, move to it using the following command.

cd redux-error-handling

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 });
  }
};
