Mô tả

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.
