Build Your REST API with Spring Boot

from HTTP fundamentals to API Mastery

What makes a good REST API?

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.

APIs are also public, which means you need to get them right from the start, because they’re very expensive to change

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.

I’ve crafted the new version of REST with Spring Boot to be the start-to-finish guide for the developer working through a Spring REST API implementation

The canonical reference for building a production grade REST API with Spring Boot. The 6 modules cover designing the API using recommended best practices and high-standard specifications, all with a critical and detail-oriented mindset.

In addition to the insightful guides on implementation, you’ll also get the knowledge needed to understand the difference between documenting and discovering an API, and learn different options for testing and safely evolving an API.

Everything I wish I had access to when I built my first API with Spring.
