Looking for a cost effective solution that adds business value?

Our GraphQL training course explains fundamental concepts and techniques including queries, mutations, subscriptions and constructing schemas. You'll learn how to use GraphQL to fetch data intelligently, describing the shape of the data you want and getting back precisely what you asked for in a single request.

We'll demonstrate how GraphQL addresses the problems of RESTful architectures, and you'll learn to build a front-end client using Apollo and React / Angular, with a back-end GraphQL server using Apollo and Node. These techniques are applicable to other languages and frameworks - let us know about your tech stack and we can customise your course for on-site delivery as a standalone workshop or part of a wider training programme.
