📂 Category Route Blocks

Category route blocks provide pre-configured HTTP endpoints for category management operations in Nodeblocks applications. These routes combine handlers, validators, and middleware to create complete API endpoints with proper authentication, authorization, and error handling.

---

🎯 Overview

Category route blocks are designed to:

• Provide complete API endpoints for category management operations
• Combine handlers with validators for secure operations
• Include authentication and authorization checks
• Support functional composition patterns
• Handle logging and error management automatically

---

📋 Route Structure

Each category route follows a consistent pattern:

• HTTP Method: Defines the operation type (GET, POST, PATCH, DELETE)
• Path: Specifies the endpoint URL with parameters
• Handler: Composed function chain for business logic
• Validators: Authentication and authorization checks
