Have you ever wondered how REST APIs work? Have you tried to understand all of the components that are required to create REST APIs? Are you a developer from a Java/PHP/Perl/Python background who is now interested in Node.js? Did you want to know how relational databases work? Or how NoSQL works? How are they different - or even similar?

Have you heard about JSON Web Tokens and token-based authentication but aren't sure how they work? Have you heard the latest buzzword GraphQL and wondered how it works?
Look no further-this course answers all of your questions! It teaches you the very basics of REST APIs including its architecture and HTTP methods, adding relational database and/or NoSQL support while also covering authentication via tokens as well as GraphQL. As a bonus, Section 10 (Appendix B) has an entire section on how to implement the REST API in an example application, including authentication for users.
