An Introduction to GraphQL APIs


Learn the basics of consuming and building GraphQL. GraphQL is a query language for building APIs and a runtime for fulfilling those queries. Originally created at Facebook, GraphQL was the internal data-fetching API that powered hundreds of billions of Facebook API calls a day. GraphQL was then open-sourced, specified, and today is a popular choice for building APIs at any scale, with language support across dozens of languages. A large ecosystem surrounds GraphQL, including popular frameworks like Apollo, Gatsby, Relay and products like Hasura. In this introduction, we will learn the "what's" and the "why's" of GraphQL, how to use GraphQL to fetch data, how to design a GraphQL schema, and then finally implement a server to resolve that schema.
