Basics Of GraphQL With Ruby On Rails

This course teaches the basics of using GraphQL in a Rails application. GraphQL is a query language invented by Facebook in 2012, and made open source in 2015. While it has certain clear advantages over REST, it also has a somewhat steeper learning curve.

Structured in a simple and accessible manner, these lectures will help you get on your way to using GraphQL to circulate data between back-end and front-end applications.

In the first section we will learn about reading data; in the second, about changing data; and the slightly more advanced third section is about protecting data.
