About This Episode:
Your Node.js server just got smarter 🧠⚡️
HTTP is stateless — but your apps don’t have to be.
In this episode, you’ll learn how to manage sessions to persist user data between requests, handle flash messages, and clean up session files automatically — all without a framework.
👉 In this episode, you’ll learn how to:
🔐 Understand the difference between cookies and sessions
🗂️ Build a simple, file-based SessionManager from scratch
💾 Store and retrieve session data safely on the server
⚙️ Add flash messages and automatic session cleanup
🧩 Use JavaScript Proxy objects to auto-save session data
By the end, your Node.js apps will remember — even when HTTP forgets 😉
