GraphQL: A data query language

This post introduces GraphQL, a data query language developed internally at Facebook to address the challenges of data fetching in native mobile applications. It highlights GraphQL's ability to define data shapes that mirror responses, its hierarchical nature, strong typing, protocol-agnostic design, introspection capabilities, and version-free evolution. The post details how GraphQL was developed to simplify data fetching from the perspective of product designers and developers, moving focus to client apps and enabling efficient data retrieval for complex mobile UIs. It also announces the open-sourcing of GraphQL, including a specification and reference implementation, and its integration with Relay and React Native as part of a complete development stack.
