Building Scalable Projects with NestJS: WebSockets, Real-Time Notifications, Email Integration, and More

What you’ll learn
Master the core concepts of NestJS and understand its powerful architecture for building scalable applications.
Learn how to set up and configure a NestJS project from scratch using TypeScript, Express, and various key libraries.
Understand database integration using both MongoDB and SQL (via TypeORM), and how to structure your data models effectively.
Build a hands-on project with MongoDB to reinforce your NestJS skills and understand real-world use cases.
Create a large-scale, production-ready application using SQL, TypeORM, and advanced NestJS features like authentication, middleware, and more.
Develop real-time features with WebSockets and integrate them seamlessly into your applications.
Learn to troubleshoot and debug your code effectively, gaining critical skills for fixing issues and improving performance.
Develop a research-oriented mindset to confidently read official documentation and learn new technologies.
Avoid the “tutorial hell” trap by learning how to think independently and solve problems on your own.
Gain a strong foundation in backend development that prepares you to work with any other framework or language in the future.

Requirements
You need to know the basics of typescript
Have knowledge of NodeJS
Understanding of expressJS is recommended but not required

Description
NestJS is a powerful and rapidly growing framework that enables developers to build scalable and efficient applications with ease. In this course, you’ll learn how to harness the full potential of NestJS to create robust backend systems.In this course, you’re not just going to learn NestJS; you’ll also master the essential skills of learning new technologies. Forget fancy slideshows and fluff—this course is all about diving deep into the core material, directly from official resources. I believe in the power of real, hands-on learning, and instead of simply repeating what’s already out there, we will focus on practical application.Why do I say “you don’t just learn NestJS”? Because in this course, I’m going to show you how to research, troubleshoot, and read documentation effectively—skills every developer needs to thrive. These aren’t just technical abilities; they are life skills for problem-solving and continuous learning, which are crucial to keep up with ever-evolving technology.Upon completing this course, you won’t just be proficient in NestJS. You’ll have developed the confidence and methodology to pick up any framework, language, or tool you wish to learn. This course will teach you how to avoid the trap of “tutorial hell”—that frustrating cycle where you rely too much on step-by-step guides without gaining true understanding. You’ll learn how to think independently, explore documentation, and solve problems—transforming you into a self-sufficient developer, ready to tackle any challenge that comes your way.What will you learn in this course?Core NestJS Concepts: We’ll start by building a solid foundation of NestJS, diving into the framework’s core features and best practices for building maintainable applications.Building a Small Application with MongoDB: Once you’re familiar with the basics, we’ll work on a hands-on project using MongoDB to help reinforce your understanding of NestJS and how to apply it in real-world scenarios.Developing a Large-Scale Application with SQL and TypeORM: Finally, we’ll scale things up by developing a large and complex application using SQL and TypeORM, integrating advanced concepts like authentication, real-time communication, and more.
