How aguzr10/dealerships-cars works

The README describes PostgreSQL schema provisioning and seed data as the repository’s product. The tree also contains a NestJS API scaffold: its controllers expose car and dealership routes, but the sampled services return placeholder strings rather than accessing the database. The API modules configure PostgreSQL connectivity, but no sampled evidence shows CRUD calls reaching it. Evidence for unsampled wiring is limited to the README and SOURCE INDEX references.

Main entry points: app.module.ts App configuration · cars.controller.ts Car routes · dealerships.controller.ts Dealership routes · car.entity.ts Car entity
