🏗️ Building a Clean Architecture API with Go, Ore, and SQLite

So you've been writing Go for a bit. Your main.go is growing. You've got a database call next to an HTTP handler next to a business rule, and somewhere in the back of your head a little voice keeps whispering "this is going to be a nightmare to test." That voice is right. And today we're going to silence it. 🤫 We're going to build a Book Library REST API from scratch using Clean Architecture - a layered design that keeps your business logic completely isolated from databases, HTTP frameworks, and anything else that changes for the wrong reasons. To wire it all together, we'll use Ore , a lightweight dependency injection container for Go. And for persistence, we'll use SQLite via the modernc.org/sqlite driver (pure Go, no CGo required - your CI pipeline will thank you 🙏). By the end of this guide you'll have: 📦 A proper 4-layer Clean Architecture project structure 🗄️ A real SQLite database with schema migration on startup 💉 Ore managing all dependency wiring, lifetimes, and startup vali
