What you will learn

Learn how to utilize NestJS to be a production ready REST API

Learn how to implement complex functionality like authentication and authorization

Learn how to write tests for your services and controllers

Learn all of the different entities provided in NestJS


As someone that utilizes NestJS on a daily basis at work and beyond, I'd love to share everything that I've learned in this course. This is the most comprehensive NestJS course on Udemy and if you don't think so, you can request a full refund.

NestJS is a progressive NodeJS framework that will allow us to build reliable scalable, and maintainable server-side backend applications with incredible ease.

In this course, you will be building two professional applications. The first will be an Expense App, where you will learn:

  • The fundamentals of NestJS

  • Different NestJS entities, like controllers, services, interceptors, pipes, and modules

  • NestJS best practices

In the second project, the Realtor App, we will learn about:

  • Interacting with a Postgress database with an ORM (Prisma)

  • Creating a database model and performing CRUD operations

  • How to authenticate and identify a user

  • How to authorize certain endpoints for specific users

  • How to properly write automated tests for our services and controllers

  • How to create custom param decorators

  • Learn about advanced NestJS entities like guards and interceptors

I am very proud of this course and I really hope you take and enjoy it. If you ever need any sort of help, please send me a message on Udemy and I will always answer your questions.

This course is good but some sections are not continued video. I'm a newbie learning may be confusing in some sections. But it is suitable for people who have skills in typescript and javascript.

Almost done with the course but I've learned so much already. The instructor covers the NestJS very well and the project is very realistic to how an app would be developed in the industry.

It could be improved in terms of redundancy in the code and in some implementations that the technology allows you to manage in a better way. In general, it is a good course for beginners since it gives you the main fundamentals of NestJS, but I do recommend investigating a little more in depth on your own the documentation of the framework since it is quite complete.

Good course globally, I'm just a bit confused about writing tests, I would suggest for a future version of this course to spend more time on that chapter

A clear and understandable course. Sometimes the code in the following video differs from what has been written so far, which makes it a bit unclear. But is an unintended but good exercise in understanding what is happening. The course ends rather abruptly, a wrap up would have been nice, possibly with some reference material or possible next steps. Overall it's a good starters course, which i would recommend to others that have some knowledge on JS but want a basic insight in what NestJS is all about.

Seems like in Section 9 part for getting home by ID is missing. By the way, good starter course for NestJS, well explained and well shown.

I've found the instructor's YouTube videos to be extremely helpful for understanding concepts that I've often struggled with. I had been thinking about getting a course on NestJS for awhile so this was an instant buy for me. So far this course is everything I've come to expect and more.
