• Change TypeComposer.addRelation arguments:
  • move argsMapper to opts.args
  • add projection to opts (relations may require some fields, that not described in GraphQL query)
• Add projectionMapper to Types. Now relation works without redundantly defining additional fields.
  • When you create relations you need query additional fields, that not in the GraphQL query. E.g. for obtaining friendList you also should add friendIds to projection. ProjectionMapper solves this problem.
