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

To implement authentication in a React app using Redux and JWT, you need to set up a Redux store, create actions for login and logout, and handle JWT tokens for user sessions.

What are the steps to set up the Redux store for authentication?

First, install Redux and React-Redux. Then, create a store, define your authentication reducer, and combine it with other reducers.

How do I handle JWT tokens after a user logs in?

After a successful login, store the JWT token in local storage or a cookie, and include it in the Authorization header for subsequent API requests.

Can you show me an example of the login action?

Sure! Here's a simple example:

export const login = (credentials) => async (dispatch) => {
  const response = await api.post('/login', credentials);
  const token = response.data.token;
  localStorage.setItem('token', token);
  dispatch({ type: 'LOGIN_SUCCESS', payload: token });
};
