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.
