SafeNode is a ready-to-use error handling system for Node.js and Express apps.
It provides a clean structure to handle all types of errors — from missing routes to async function failures — without writing repetitive try/catch blocks.

This template is lightweight, fully commented, and ready to integrate into any backend project instantly.

🧠 How It Works

• You throw an error using AppError.

• asyncHandler catches it and forwards to Express.

• errorHandler sends a clean JSON response.

• If no route matches, notFoundHandler sends a 404 response.

Everything is already connected — just plug and use.
