CRUD Operations with TypeORM

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 the app.service.ts or app.controller.ts files.
