00:00 Introduction: What are Edge Functions? 00:30 The basics of server routing (WordPress vs NextJS) 03:27 The physical internet: Undersea cables, speed of light, and latency 06:45 How CDNs fix latency for static content 08:27 The database problem: Why dynamic content is slow 10:14 The solution: Using Edge Functions for instant dynamic responses 13:30 Summary & Conclusion Why you should care about Edge Functions ⚡ Ever wonder how websites load instantly, even when the server is on the other side of the world? In this video, we dive deep into Edge Functions and how they are revolutionizing web development. We break down the physical infrastructure of the internet—from the Wi-Fi router in your house to the undersea fiber optic cables crossing the Atlantic Ocean—to understand why latency happens. We explore how CDNs (Content Delivery Networks) like Cloudflare solve these latency issues for static content, and then tackle the big problem: how do we keep things fast when we need to use a database for dynamic content or user logins? That's where Edge Functions come in. Learn how these small, incredibly fast blocks of code execute right near the user to verify tokens, route requests, and drastically speed up the user experience for complex applications. Whether you're building a simple NextJS site or a massive platform like Booking.com, understanding the edge is crucial for modern development.
