Questions tagged [graphql]

For questions about GraphQL, an API technology designed to describe the complex, nested data dependencies of modern web applications.

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

There are GraphQL implementations in almost every server-side language, and powerful clients for most UI platforms.
