Building a Production-Ready Web App from Scratch (Part 4): Setting up our NestJS Server

In Part 4 of Building a Production-Ready Web App from Scratch, we set up the foundation of our backend using NestJS. In this video, you’ll learn how to configure a clean, scalable, and production-ready NestJS server with multiple environments, strict validation, and proper startup behavior. We walk through setting up a dedicated environment folder, creating separate .env files for development, staging, and production, and using the @nestjs/config module with Joi validation to ensure your server never starts with missing or invalid configuration. You’ll also learn how to structure your project for real-world deployment and how to use Nest’s built-in watch mode for smooth development. By the end of this video, you’ll have a fully validated environment system, a clear server bootstrap message that shows which mode you're running in, and a backend that’s ready to grow with your application. This is the foundation we’ll build on as we move into database connections, authentication, and API development in upcoming parts.
