More and more teams are choosing GraphQL instead of (or along with) REST for their web APIs. GraphQL queries give clients great flexibility in the way they request data from the server, preventing issues such as fetching or under fetching of data, and allowing multiple resources to be retrieved in a single request.
The examples use Apollo Server with Node.js and Express on the backend and Apollo Client with React on the frontend. The aim however is not just to cover specific GraphQL libraries, but to give you a more general understanding of the underlying concepts. For instance, Apollo Client is only introduced after learning how to write a simple client "by hand" to make sure you understand GraphQL over HTTP format.
