NestJS: The Complete Developer’s Guide

Authentication/Authorization? Covered.  Automated Testing? Yep, it’s here!  Production Deployment? Of course!

Congratulations! You’ve found the complete guide on how to build enterprise–ready apps with NestJS.

NestJS is a backend framework used to create scalable and reliable APIs.  It is a battery–included framework; it includes tools to handle just about every possible use case, from data persistence, to validation, to config management, to testing, and much, much more.  This course will help you master Nest. By the time you complete this course, you will have the confidence to build any app you can imagine.

Throughout this course you will build a series of apps with growing complexity.  We use as few libraries and tools as possible.  Instead, you will write many custom systems to better understand how every piece of Nest works together.  Each application you build includes discussion on data modeling and persistence. We will first save records in a simple file–based data store (built from scratch) and eventually work our way up to saving data in a production–grade Postgres instance.

Testing is a fundamental topic in Nest. A tremendous amount of functionality in Nest is dedicated to making sure your project is easy to test. This course follows Nest’s testing recommendations, and you will write both integration and unit tests to ensure your project is working as expected. Although testing can sometimes be confusing and boring, I have put special care into making sure the tests we write are expressive, fast, and effective.  You will be able to use this knowledge on your own projects, even those that don’t use Nest!
