What problem does it solve?

This Skill addresses the challenge of creating consistent and reliable backend middleware components, ensuring predictable behavior for critical functionalities like authentication, validation, logging, and error handling.

Core Features & Use Cases

• Modular Design: Develop reusable middleware functions for common backend concerns.
• Ordered Execution: Define clear execution order for middleware chains.
• Error Handling: Implement robust error boundaries to gracefully manage exceptions.
• Use Case: Building an API where requests must first be authenticated, then validated against a schema, and finally logged before reaching the main application logic.

Quick Start

Design a set of backend middleware components for an Express.js application.
