_ REST WITH SPRING

Build Your REST API with Spring Boot|

Production-grade REST API with Spring 6 and Spring Boot 3

A REST API is a must-have for any serious application. And in our ecosystem, building the API with Spring Boot is, of course, the clear choice and very much in-demand.

The lessons start with the fundamentals of what makes a good REST API, working on a practical project with Spring Boot. Building on this, we’ll see more advanced tactics like HATEOAS, different types of tests you can write to maintain your API, documentation, error handling, and efficient input validation for the API.
