Expand description
Handler that executes GraphQL
queries in the given schema
The handler responds to GET requests and POST requests only. In GET
requests, the query should be supplied in the query
URL parameter, e.g.
http://localhost:3000/graphql?query={hero{name}}
.
POST requests support both queries and variables. POST a JSON document to
this endpoint containing the field "query"
and optionally "variables"
.
The variables should be a JSON object containing the variable to value
mapping.

Build a new GraphQL handler
The context factory will receive the Iron request object and is expected to construct a context object for the given schema. This can be used to construct e.g. database connections or similar data that the schema needs to execute the query.
