GraphQL

GraphQL is a query language for APIs and a runtime for fulfilling those queries with existing data. Developed by Facebook in 2012 and open-sourced in 2015, GraphQL provides a complete and understandable description of the data in an API, gives clients the power to ask for exactly what they need, and enables powerful developer tools. It is maintained by the GraphQL Foundation under the Linux Foundation.

GraphQL is profiled on the APIs.io network. Tagged areas include Data Fetching, GraphQL, Query Language, and Specification.

The GraphQL catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

GraphQL’s developer surface includes developer portal, documentation, getting-started guide, engineering blog, and 7 more developer resources.
