About This Episode:
Every web app starts with a server — and in Node.js, that journey begins with the HTTP module. In this episode of JavaScript on the Server, we’ll peel back the curtain on how requests and responses actually flow between the browser and your app.
✨ What you’ll learn:
- Why the HTTP module is the core engine of Node.js servers
- How the client-server request/response cycle really works
- Building a minimal web server from scratch (no frameworks required!)
- Getting hands-on with the req (IncomingMessage) and res (ServerResponse) objects
- Key concepts to set you up for routing, APIs, and beyond
Whether you’re new to backend dev or just curious how Node powers the web, this episode will give you the foundation you need to level up.
