Build Real App with React: User Authentication

This episode is the most important in the whole series so far, because here we’ll handle fullstack user authentication. Here is the plan:

• setup mongoose and create User model
• implement user authentication by searching for user in database and check password
• on react side we’ll implement conditional Login/Logout links, that depend on user authentication state
• make login permanent by storing JWT in local storage, so user can reload page and stay logged in
• user logout
