How vict0r-starlit-reader/library-management-system works
This repository is a NestJS library backend with a PostgreSQL database managed by Prisma. Its sampled runtime workflow starts the Nest application, serves a root HTTP endpoint through the controller and service, and initializes a Prisma connection. The README describes a broader data model—patron/librarian roles and a normalized book/genre catalog—plus migrations and seed data. The sampled controller only returns “Hello World”; no catalog-management API was shown, so those capabilities are represented as schema and data setup rather than runtime routes.
