*** Course delivered in English (UK) *** GraphQL Course Overview

GraphQL is a query language for APIs and a query runtime engine. It's an increasingly popular alternative to REST given it enables the client to specify the shape of the representation and it minimises the number of requests required to obtain the desired data.

This course comprises sessions dealing with prerequisite topics including HTTP and REST APIs,core GraphQL theory,the building of GraphQL services and clients,queries,types,and yet more GraphQL theory including introspection and best practices.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Delegates have the option of coding in either Java,Python,or JavaScript.
