Description

GraphQL is a query language and runtime technology widely used to develop fast and flexible APIs. In 2012, Facebook created GraphQL to improve client and server communication. To accomplish this, GraphQL provides the following:

  • An efficient, developer-friendly, data-fetching API
  • A fast, flexible query language
  • Easy integration with existing code sources and environments

In this lab, you will learn about the core features of GraphQL and how it compares to traditionally-structured REST APIs. You will be provided with a predefined data set which you will access using various GraphQL queries.
