How can I implement authentication in my React Native app using Redux?

To implement authentication in your React Native app using Redux, you can follow these steps: 1. Set up Redux in your project. 2. Create actions for login, logout, and registration. 3. Create a reducer to handle authentication state. 4. Use middleware like Redux Thunk for async actions. 5. Connect your components to the Redux store.

What kind of actions do I need for authentication?

You will need at least three actions: LOGIN, LOGOUT, and REGISTER. Each action will handle the respective authentication process.

Can you show me an example of a login action?

Sure! Here's a simple example of a login action using Redux Thunk:

export const login = (credentials) => async (dispatch) => {
  dispatch({ type: 'LOGIN_REQUEST' });
  try {
    const response = await api.login(credentials);
    dispatch({ type: 'LOGIN_SUCCESS', payload: response.data });
  } catch (error) {
    dispatch({ type: 'LOGIN_FAILURE', error });
  }
};

How do I handle authentication state in my reducer?

In your reducer, you can manage the authentication state by handling the actions you defined. For example:

const initialState = { isAuthenticated: false, user: null, error: null };

const authReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'LOGIN_SUCCESS':
      return { ...state, isAuthenticated: true, user: action.payload };
    case 'LOGOUT':
      return initialState;
    case 'LOGIN_FAILURE':
      return { ...state, error: action.error };
    default:
      return state;
  }
};
