Introduction to REST Services with Grails 3

Introduction to REST Services with Grails 3 is a live, instructor-led training experience.

REST is an important part of modern web applications. Single page application (SPA) frameworks, such as AngularJS and React, require a REST backend, for which Grails is a perfect fit. Microservice architectures rely on components communicating with each other through REST APIs. Grails 3 offers many features specifically related to simplifying the task of publishing REST APIs.
