This document discusses LoopBack and GraphQL. It provides an overview of LoopBack, including its history with IBM acquisition and paid services. It describes LoopBack as model-driven and isomorphic backend as a service (MBaaS). Examples are given of mapping LoopBack models to GraphQL schemas and types. Benefits of GraphQL like strong typing, documentation and client tools are highlighted. Examples of GraphQL queries with includes and pagination are shown. Security features of LoopBack like authentication, roles and endpoint restriction are also mentioned.
