GraphQL

• Query language and runtime for web APIs. 
• Developed by FB.
• While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request. Apps using GraphQL can be quick even on slow mobile network connections.
• A GraphQL server can process a client query using data from separate sources and present the results in a unified graph.
• GraphQL is a data query and manipulation language that allows specifying what data is to be retrieved ("declarative data fetching") or modified.
