Performance results:

NOTE: This was conducted by incrementally uncommenting the resolvers and imports from NestjsQueryGraphQLModule in the demo.module.ts file. The data below was gathered by saving to trigger a reload three times and doing a mental average/rounding.

  1. docker-compose up -d (spin up db)
  2. npm run start:dev
  3. Update the demo.module.ts file (noted above) then save to trigger reload
  4. Check the console for the performance load time
