Part 0 — Web Fundamentals for Modern Full-Stack

Before you write a single line of React or NestJS code, you need a robust development environment. In this guide, we’ll set up Node, pnpm, PostgreSQL, and VS Code the right way—like a professional full-stack engineer.

Before coding your first API, you must understand how data moves across the web. Let’s unpack the invisible conversation between your React app, NestJS backend, and PostgreSQL database.

Strong full-stack developers master the language behind the stack. Let’s bridge modern JavaScript fluency with TypeScript discipline — the combination powering React and NestJS.

Before JSX and styled-components, there’s structure and style. Understanding HTML5 and CSS3 fundamentals ensures your React interfaces are fast, accessible, and production-ready.

Great developers don’t just write code — they manage it. Learn how Git and GitHub shape teamwork, history, and CI/CD integration in professional full-stack environments.

A strong full-stack developer builds systems, not scripts. Before diving into React and NestJS code, let’s design a maintainable project structure and engineering mindset.
