NestJS: The Complete Developer's Guide

Build Enterprise-Ready Apps with NestJS: A Complete Guide

Unlock the power of NestJS and learn to develop scalable and reliable APIs with this comprehensive course. NestJS is a powerful backend framework, often described as "battery-included," providing tools for everything from data persistence and validation to configuration management and testing.

This course guides you through building increasingly complex applications, focusing on understanding the core principles of NestJS by writing custom systems rather than relying heavily on external libraries. You'll gain practical experience with:

• Data Modeling & Persistence: Learn to store and retrieve data, starting with a simple file-based store and progressing to a production-ready Postgres instance.
• Testing: Master unit testing and integration testing using NestJS's built-in testing features. We'll ensure your code is robust and reliable.
• TypeScript: Write clean, correct code with TypeScript, a key component of NestJS. A free appendix is included to get you started if you're new to TypeScript.
• Authentication & Authorization: Implement a secure authentication system from scratch to manage user logins and permissions.
• Dependency Injection: Master dependency injection for writing reusable and maintainable code.
• Data Validation: Implement automatic validation of incoming requests to ensure data integrity.
• Data Transfer Objects (DTOs): Format outgoing response data with a custom DTO system.
• Guards & Interceptors: Handle incoming requests and outgoing responses with Guards and Interceptors.
• Nest Modules: Segment your code into reusable Nest Modules for better organization.
• Database Migrations: Add structure to your database using migrations.
• TypeORM: Understand how TypeORM handles data relationships and perform complex queries.

This course emphasizes a deep understanding of NestJS internals, empowering you to adapt and customize the framework to meet your application's specific needs. You'll learn how to:

• Securely deploy your app to production.
• Write automated tests for your code.
