📄️ File Uploads (Multer)
Handling file uploads in Express is notoriously tricky. The "unopinionated" way often leads to messy routes mixed with file system logic.
📄️ Sending Emails (Resend)
In a production application, you never want to clutter your Controllers with email logic or HTML template strings.
📄️ Request Validation (Zod)
In a scalable application, you must never trust user input.
📄️ Pagination & Filtering
As your application grows, you cannot just findAll() and return 1,000 records at once. It hurts performance and user experience.
