Building a Products REST API in NestJS: From Database to JSON Response: E-4

We have a products table sitting in Postgres. Now it is time to expose it to the world through a clean REST API built in NestJS.

This episode covers creating a NestJS resource for products: the module, service, and controller. You will write the Prisma queries, shape the response, and hit a real URL to get back real product JSON. Jay also walks through NestJS dependency injection as it applies here so you understand the pattern, not just the code.
