What are the different authentication methods for Node.js applications?
There are several authentication methods for Node.js applications, including JWT, OAuth, and session-based authentication.
Can you explain how JWT works?
JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: header, payload, and signature.
What are the advantages of using OAuth?
OAuth allows third-party applications to access user data without sharing passwords, enhancing security and user experience.
Are there any libraries you recommend for implementing these methods?
Yes, for JWT, you can use 'jsonwebtoken'. For OAuth, 'passport' is a popular choice. Both have extensive documentation.
