What is the difference between authorization and authentication in Express.js?
Authentication is the process of verifying who a user is, while authorization determines what resources a user can access.
Can you give me an example of how to implement both in an Express.js application?
Sure! You can use middleware for authentication (like Passport.js) and then check user roles for authorization.
What are some common authentication methods used in Express.js?
Common methods include JWT (JSON Web Tokens), OAuth, and session-based authentication.
How do I secure my API endpoints in Express.js?
You can secure your API by using middleware to check for valid tokens and user permissions before granting access.
