Object Relational Mappers (ORM) are becoming popular in building modern backend applications as they help maintain a consistent codebase, improve security, and provide ease in working with different databases. Also, TypeScript has almost become a must-use language for building JavaScript applications.

In this course, you’ll start by getting familiar with Node.js and Express. You’ll then go over the main features of TypeScript and its advantages over JavaScript. Next, you’ll learn how to do a Docker setup of PostgreSQL. Moreover, this will be followed by introductions to two of the most popular TypeScript ORMs for Node.js: Prisma and TypeORM. Along the way, you’ll practice your skills by building two projects. In the end, you’ll explore some advanced features of these ORMs.

This course will equip you with the skills, knowledge, and hands-on experience to work with SQL databases and Node.js using TypeScript ORMs.
