What are some examples of using Redux actions?

Can you give me some examples of Redux actions?

Sure! Redux actions are plain JavaScript objects that have a type property. For example, an action to add a user might look like this: { type: 'ADD_USER', payload: { name: 'John Doe' } }.

What about asynchronous actions?

For asynchronous actions, you can use middleware like Redux Thunk. An example would be:

const fetchUser = (userId) => async (dispatch) => { const response = await fetch(/api/users/${userId}); const user = await response.json(); dispatch({ type: 'FETCH_USER_SUCCESS', payload: user }); };

How do I handle errors in actions?

You can dispatch an error action if something goes wrong. For example: dispatch({ type: 'FETCH_USER_ERROR', payload: error });

Can you show me a complete example?

Absolutely! Here's a simple example of a Redux action creator for fetching users:

const fetchUsers = () => async (dispatch) => { dispatch({ type: 'FETCH_USERS_REQUEST' }); try { const response = await fetch('/api/users'); const data = await response.json(); dispatch({ type: 'FETCH_USERS_SUCCESS', payload: data }); } catch (error) { dispatch({ type: 'FETCH_USERS_ERROR', payload: error }); } };
