 ## Only [GraphQL over HTTP](https://graphql.github.io/graphql-over-http/)
 
 This is the official [GraphQL over HTTP spec](https://graphql.github.io/graphql-over-http/) reference implementation and as such follows the specification strictly without any additional features (like file uploads, @stream/@defer directives and subscriptions).
