What problem does it solve?

API design for Express projects often collapses into tangled middleware, poorly defined boundaries between validation, authentication, and domain logic, and inconsistent error handling. This Skill helps teams plan clean, scalable architectures with explicit route grouping, middleware separation, and service layering.

Core Features & Use Cases

• Define route groups with shared middleware, input validation, and error handling.
• Separate concerns into route handlers, validators, auth, and services.
• Provide a reference architecture and example folder structure for projects.
• Offer guidelines for testing and instrumentation.

Quick Start

Provide a concrete, scalable Express API design blueprint for a new or existing project.
