One mistake I made early as a developer: I used to build backend APIs just to “make things work.” No structure. No separation. Everything in one place. It worked… until it didn’t. As projects grew, things started breaking, debugging became painful, and adding new features felt risky. Here’s what improved my backend development a lot (Node.js / Express / NestJS): • Clear folder structure (controllers, services, routes, models) • Keeping business logic out of controllers • Proper error handling (centralized) • Using middleware effectively • Writing reusable services instead of duplicating logic Simple things—but they make a huge difference when your app scales. Still refining my approach, but this structure has saved me countless hours. How do you usually structure your backend projects? #nodejs #backenddevelopment #javascript #fullstackdeveloper #webdevelopment
Great reflection — most of us learned this the hard way. “Making it work” scales very poorly, especially on the backend where complexity grows fast. The shift usually happens when you realize that structure isn’t overhead… it’s what enables speed later on. The point about keeping business logic out of controllers is huge. Controllers should stay thin — once they start accumulating logic, everything becomes harder to test, reuse, and reason about. One thing I’d add: defining clear boundaries between modules/services early on. Not just folders, but ownership of responsibilities. It prevents that “everything depends on everything” situation that kills maintainability. Simple patterns, big long-term impact. This is the kind of discipline that really separates projects that scale from the ones that collapse 😊
So relatable. Most of us start with “just make it work” and then regret it later 😅 Clean structure + separating logic really does save you when the project grows.

2wHow about pattern for handle the logic business?? I just see the direct services.👀
