I Coded a Rate Limiter From Scratch — No Libraries, Just Logic 🔥

Описание: Node.js Rate Limiter from Scratch: Stop API Overload (Token Bucket Algorithm Explained) 🤯 | Before: Chaos 😵 | After: Smooth 🚀

Ever faced a server crash due to a traffic surge or a DDoS attack? This Node.js tutorial teaches you the Token Bucket Algorithm, the core logic behind effective rate limiting. We build an Express middleware in TypeScript to protect your backend API and handle burst traffic efficiently, giving you a production-ready solution for ultimate API security and performance.

In this video, I take you behind the scenes and build a powerful custom Rate Limiter from scratch — no NPM packages, no shortcuts, just pure logic.

💻 What’s Inside:
✅ Understanding how rate limiting actually works (The Token Bucket deep dive)
✅ Building a *production-ready middleware* step-by-step in TypeScript
✅ Handling burst traffic and auto cleanup for server memory
✅ Real-time demo: before vs after rate limiter performance on an Express server
✅ Clean, interview-ready implementation

🧠 Tech Stack: *Node.js | Express | TypeScript*

📈 Why You’ll Love It:
If you’re tired of blindly using libraries and want to understand the logic behind them, this video will level up your backend skills instantly. Perfect for devs preparing for *system design interviews* or just wanting to flex their backend mastery.
