JSON Web Token (JWT) Authentication with Node.js

JSON Web Token (JWT) is a low overhead option for authentication that is easy to implement and scales with your application. There is no need to store session data as everything you need is stored in an encoded string sent in the JWT, significantly reducing database overhead for your servers. In this course, we will build a simple authentication server that will act as a token issuer, and we will use those tokens to access resources on an API.
