graphql/express-graphql

This project is deprecated and has been replaced by `graphql-http`, the official GraphQL over HTTP reference implementation. `express-graphql` was the original reference implementation for creating GraphQL HTTP servers with Express, but it is now unmaintained. Users are encouraged to migrate to `graphql-http` or other full-featured GraphQL server options like `graphql-yoga`, `apollo-server`, or `postgraphile`.
