One of the best ways to learn a technology is to build it from the ground up. That’s the premise of CodeCrafters, which offers a catalog of challenges to build popular tools and technologies from scratch (think things like Docker, Git, Redis, a DNS server, etc.).

In this video, I’ll walk you through the “Build your own HTTP server” challenge. Using the platform, you’ll build a HTTP server that’s capable of handling simple GET/POST requests, serving files and handling multiple concurrent connections. Along the way, we’ll learn about TCP connections, HTTP headers, HTTP verbs, handling multiple connections and more.
The idea of CodeCrafters is to “learn by doing,” and there are lots of ways to write the code. I’ll show you code examples and hints that you can use to get you started writing your own code. There’s no completed code for download (as that would kind of defeat the point ?).
