How can I implement authentication in a React app using context?

You can use the React Context API to manage authentication state globally. Start by creating an AuthContext.

What should I include in the AuthContext?

Include state variables for user data and authentication status, along with functions to log in and log out.

How do I provide this context to my components?

Wrap your application in the AuthContext.Provider and pass the authentication state and functions as value.

Can you show me a code example?

Sure! Here's a simple example:

const AuthContext = createContext();

const AuthProvider = ({ children }) => {
  const [user, setUser] = useState(null);

  const login = (userData) => setUser(userData);
  const logout = () => setUser(null);

  return (
    <AuthContext.Provider value={{ user, login, logout }}>
      {children}
    </AuthContext.Provider>
  );
};
