Building a URL Shortener in Go | Architecture, Storage, and Real Code Walkthrough

In this video, we dive deep into building a real-world URL Shortener service in Go, from scratch. Using clean architecture principles, you’ll see how to organize your Go project using idiomatic best practices — covering everything from in-memory storage to Base62 encoding, service layering, HTTP handlers, and more!

We break down the project hosted on GitHub and show you real code, explain how it works, and how you can build and run it yourself.
