How can I implement authentication in a React app using Redux and Async Storage?

You can manage authentication state in Redux and use Async Storage to persist user data. Start by setting up Redux with actions and reducers for login and logout.

What actions do I need to create for login and logout?

You'll need a LOGIN action to set the user data in the state and a LOGOUT action to clear it. Make sure to handle these in your reducer.

How do I store the user token in Async Storage?

You can use the AsyncStorage.setItem method to store the token after a successful login, and AsyncStorage.removeItem to clear it on logout.

Can you show me a code example for the login action?

Sure! Here's a simple example:

const login = (userData) => async (dispatch) => {
  const token = await authenticateUser(userData);
  await AsyncStorage.setItem('userToken', token);
  dispatch({ type: 'LOGIN', payload: userData });
};
