What are the different authentication methods for Node.js APIs?

There are several authentication methods for Node.js APIs, including Basic Auth, JWT, OAuth, and API keys. Would you like to know more about any specific method?

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: a header, a payload, and a signature. The header typically consists of the type of token and the signing algorithm. The payload contains the claims, and the signature is used to verify that the sender of the JWT is who it says it is.

What are the advantages of using OAuth?

OAuth allows third-party applications to access user data without sharing passwords. It enhances security and provides a better user experience by enabling single sign-on.

Are there any libraries you recommend for implementing these methods in Node.js?

Yes, for JWT, you can use 'jsonwebtoken'. For OAuth, 'passport' is a popular choice. For API key management, you can use 'express-api-key'.
