Description

Dive into modern web development as you build a feature-rich URL Shortening Service from the ground up. This comprehensive course is designed to provide you with a thorough understanding of TypeScript, PostgreSQL, Koa.js , REST, Knex.Js, and the MVC design pattern, as well as practical experience in applying these technologies and concepts to a real-world project.

In this course, you will start by setting up your development environment and configuring the required tools for an optimal workflow. You will then dive into database configuration and management using PostgreSQL, learning how to create and execute migrations to set up your database schema. The course also covers the use of TypeScript to create efficient and scalable models that interact with the database, as well as the implementation of services to handle URL-related operations and other application logic.
