3 directories, 7 files

• entity folder
  • structured based on entity level abstraction
    • has GraphQL Type Definition
    • has GraphQL Resolver
  • has posibillity of full graphql syntax support
    • not ts but .graphql files
  • expose typeDefs and resolvers
• index.ts file
  • expose executable schema through makeExecutableSchema function

Design Rule

1. Focus on abstracted API
   • API should be abstracted. It doesn't care about concrete implementation or product
   • eg: GraphQL should not be affected by what database is used
2. Focus on Graph Model
   • Data should be consumed by entity level
   • It means that normalizing data model is required.
