This course covers the REST API fundamentals from scratch.

The source code and PDF files (class notes) are available for download.

* What is REST API?

REST stands for Representational State Transfer. It’s a set of rules that developers use to build APIs that work over the web, just like the websites you visit in your browser. When an API follows the rules of REST, we call it a REST API.

* What is Spring Boot?

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily.

The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration repeatedly.

Spring Boot is a very popular framework for developing REST web services and microservices.
