express-error-handling

What problem does it solve?

This Skill provides a comprehensive and structured approach to handling errors in Express.js applications, ensuring consistent error responses, improved debugging, and graceful application shutdown.

Core Features & Use Cases

• Custom Error Classes: Define specific error types (e.g., NotFoundError, ValidationError) for better error categorization.
• Centralized Error Handler: A single middleware to catch and format all errors.
• Async Error Handling: Simplifies handling errors in asynchronous route handlers.
• Graceful Shutdown: Implements mechanisms for shutting down the server and closing connections cleanly.
• Use Case: Implement this middleware in your Express.js API to automatically catch and log any unhandled exceptions, return standardized JSON error responses to clients, and ensure the application shuts down safely during deployment or unexpected failures.

Quick Start

Integrate the errorHandler middleware into your Express application after defining your routes.
