apollostack/graphql-server - how to get the fields requested in a query from resolver

2020-Jan answer

The current answer to getting the fields requested in a GraphQL query, is to use the graphql-parse-resolve-info library for parsing the info parameter.

The library is "a pretty complete solution and is actually used under the hood by postgraphile", and is recommended going forward by the author of the other top library for parsing the info field, graphql-fields.
