What are the main differences between JWT and session-based authentication in Node.js?
JWT (JSON Web Tokens) are stateless and can be used across different domains, while session-based authentication is stateful and stored on the server.
Which one is more secure for a Node.js application?
Both can be secure if implemented correctly, but JWT can be more vulnerable to certain attacks if not properly signed and validated.
Can you explain how to implement JWT in a Node.js app?
Sure! You can use libraries like 'jsonwebtoken' to create and verify tokens. Start by installing it and then create a token after user login.
What are the advantages of using sessions over JWT?
Sessions can be easier to manage and invalidate, and they don't expose user data in the token itself, which can enhance security.
