Resolve only the requested fields

[iainmckay]

Is there a recommended way only to resolve the fields that the consumer has requested? In our model we have a few run-time calculated fields, ideally these aren't resolved on every request if the consumer does not actually ask for them.

Poking around the code I can't see a way to find the actual fields requested in the field resolver. I can see the entire query but as a field can be exposed from multiple nodes in the graph it's hard to infer the context it is being resolved for.

Thanks

Yep, Blonde moment. ResolveInfo::getFieldASTList()

Sorry :)
