Introduction to Grails 3

Grails started out as a plugin-centric, Groovy-based framework for building monolithic web applications analogous to Ruby-based Ruby on Rails.

However, Grails has evolved with the web to become a much more flexible framework suitable for building microservices, web service engines for Single-Page Applications, and of course, full blown web application monoliths.

This session is an introduction to the exciting, dynamic world of Grails 3.

In this session we'll introduce the following topics to reveal the power of Grails to produce web applications and web services.

• A very brief introduction to Groovy
