In this video, we build a production-ready NestJS backend for a full-stack e-commerce application.
You’ll learn how to structure a scalable monolithic API, apply real-world backend best practices, and prepare your application for production and long-term growth.
This series focuses on real engineering, not tutorials you forget after watching.
🚀 What you’ll learn in this video
How to structure a NestJS backend for production
How real teams design scalable monolithic architectures
Backend best practices used in real-world applications
How this backend integrates later with Next.js, Docker, CI/CD, and AWS
🛠️ Technologies used in this series
NestJS, Next.js, Prisma, PostgreSQL, Docker, CI/CD, AWS, Neon(https://neon.com)
📚 Backend concepts covered
Authentication & Authorization – Secure your API using JWT access tokens and refresh tokens
Modules, Controllers & Services – Clean, modular, and maintainable architecture
Dependency Injection – Write scalable, testable, and extensible code
DTOs & Validation – Build a robust API that handles data safely
Database Integration with Prisma – Type-safe and efficient database access
Swagger Documentation – Auto-generated API documentation
CORS Security – Protect your API across domains
Guards – Advanced route protection and authorization logic
By the end of this part, you’ll have a secure, well-documented, production-ready backend ready to power a real frontend.
This is part of a step-by-step full-stack series where we build a complete e-commerce platform from scratch in 2026.
