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.


This course provides participants a thorough understanding of the following topics through lectures, real-world examples, and hands-on practice:

  • Grails' support for building REST APIs
  • Publishing APIs
  • Versioning APIs
  • Customizing response content
  • Grails and REST security
  • Interacting with a database from a REST API


To get the most out of this course, students should at least be familiar with the Grails framework and have a basic understanding of REST at a high-level. No particular expertise with Groovy, Grails, or REST is required.


The following topics are covered in this course:

  • Quick Introduction to REST
  • GORM and REST
  • Grails Views
    • JSON Views
    • Markup Views
