A beginner’s guide to creating a NestJS app with base functionality, required in average web application


What you'll learn
Set up the base NestJS application for your web project
Dockerize a NestJS app with a MySQL database

Authentication logic with email confirmation
Authorization logic with roles and permissions
Integration testing

Requirements
Basic understanding of how the web works
Basic knowledge of JavaScript and TypeScript

Description
Master the fundamentals of building a base (skeleton) NestJS application with this comprehensive course. Designed for junior full stack developers, this course will teach you how to set up and structure your NestJS app from scratch, covering everything from initial configuration to advanced testing.
We’ll start by setting up NestJS with essential configurations, Docker, and useful scripts for smooth development. Then, you’ll dive into the Config module, where you’ll learn about environment variables, module configuration, and validation. Next, we’ll move on to database setup, focusing on data sources, running migrations, and establishing a strong foundation for your app’s domain models.
Authentication and authorization will also be thoroughly covered, teaching you how to manage user sessions, roles, permissions, and guards. You’ll implement custom exception filters and validation pipes, ensuring robust error handling in your app. We’ll also explore email confirmation for user registration and security.
Finally, we’ll test the entire application, ensuring that the system functions as expected. You’ll set up a test environment, use factories, and write controller tests for authentication, roles, and users.
By the end of this course, you’ll have a fully functioning base NestJS app, ready to scale and adapt for future projects.
