History
While the GraphQL specification was first made public by Facebook in 2015,
GraphQL has been a key component of their mobile application deployment since
2012.
GraphQL is a query language for your API, and a server-side runtime for executing
queries by using a type system you define for your data. GraphQL isn't tied to any
specific database or storage engine and is instead backed by your existing code
and data.
GraphQL doesn’t store data
