NestJS: The Complete Developer's Guide

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, which means it includes tools for handling just about every possible use case—from data persistence to validation, config management to testing, and much more.

Mastering NestJS

This course will help you master NestJS. By the end of this course, you'll have the confidence to build any application you can imagine. Throughout the course, you'll develop a series of applications with growing complexity. We utilize as few external libraries and tools as possible. Instead, you'll write many custom systems to understand how each piece of Nest works together. Every application built includes discussions on data modeling and persistence, starting from a simple file-based datastore and advancing to a production-grade Postgres instance.

Focus on Testing

Testing is a fundamental aspect of NestJS, with substantial functionality dedicated to making projects easy to test. This course follows Nest's testing recommendations by incorporating integration and unit tests to ensure your project functions as expected. Although testing can be challenging and boring, special attention has been made to ensure the tests we write are expressive, fast, and effective, which you can apply to any project—even those that don't use Nest!

Leverage TypeScript

The use of Typescript throughout this course ensures you're writing clean and correct code. Unfamiliar with Typescript? Not to worry! A free appendix is included at the end to get you up to speed. Typescript helps catch errors and bugs in your code before you even run it. If you're new to TypeScript, you're in for a treat!

Why This Course?

I struggled to learn NestJS due to the many outdated tutorials and unclear documentation. Nest itself can be difficult to understand. This course is designed to save you time and money, providing the essential knowledge needed to master NestJS. You'll find learning Nest to be a delightful experience while gaining a vast amount of knowledge.
