    • QueryUtility (is a utility for TableQuery variable)
    • SchemaGenerator (is a utility for generate DDL)
  • views
    • graphiql.scala.html (is ui for graphql but is not a mandatory because you can request a api from Postman or anything that can support GraphQL)
• conf
  • evolution
    • default
      • 1.sql (for generate database. is auto generate where /schema endpoint was called)
  • application.conf (notes for implement the modules you must write configuration like play.modules.enabled += "modules.RoleModule" and play.modules.enabled += "modules.DBModule". if you not write that you can have a error message like "CreationException: Unable to create injector, see the following errors:" and a message no implementation for repositories blablabla)
  • logback.xml (for setup logger)
  • routes
• build.sbt (all dependencies are written here)

To Do List for write GraphQL Code

1. write a model and define a table for slick
2. write a repository like crud for your model (trait of repository and repository implementation)
3. write modules for repository and include DbModules for DB Configuraion
4. write configuration for modules in application.conf
5. write service (1 service 1 model and call repository)
6. write graphql type or input type in GraphQLType and write Input type in package graphql.input
7. write resolver for resolve a query or mutation from request (1 resolver 1 models and called service)
8. write schema definition in SchemaDefinition
9. write GraphQL for combine all schemas query and mutation
10. write controllers (only single endpoint for graphql but if you use graphiql you must add one endpoint for graphiql)
11. add a route for graphql (POST endpoint and if you use graphiql you must add one root)
