How To Manage Data with GraphQL


GraphQL is an open-source query language and runtime for manipulating APIs. GraphQL was designed by Facebook in 2012 (and released publicly in 2015) to solve various weaknesses with traditional REST architecture by making a new system that is declarative, client-driven, and performant.

This series covers the basics of GraphQL, beginning with important terminology and concepts. You’ll also create an Express API server in Node.js that serves up a GraphQL endpoint, giving you hands-on practice with building a schema and using operations (such as queries and mutations) and resolver functions.
