Overview
In this lesson, we’ll look at CRUD operations. We’ll be using NestJS as the API library. It includes three basic files:
app.controller.ts
: This file handles all the routes, for example,/get/employees
.app.service.ts
: This file has the algorithms and implementations that connect with databases and third-party APIs.app.module.ts
: This module registers other modules (for example, entities) that are used in theapp.service.ts
orapp.controller.ts
files.
