Building a Simple Notes REST API with Go and Fiber

When learning a new web framework, I like to avoid huge starter kits and focus on something small, useful, and easy to reason about. That is exactly why I built a notes REST API with Go and Fiber . The goal was not to create a production-ready SaaS, but to understand the pieces that matter when starting with Fiber: routing, handlers, middleware, error handling, and a clean project structure. Why Fiber ? Fiber is attractive because it gives you a very approachable developer experience while still feeling fast and lightweight. It is inspired by Express, but built for Go, and it keeps the routing and middleware story simple enough that you can focus on your API design instead of fighting the framework. For this project, I wanted something that would let me practice the basics of a REST API without adding unnecessary complexity. So instead of starting with a database, authentication, migrations, and Docker, I began with an in-memory notes store and a simple layered structure. That let me f
