📂 Category Feature Blocks

Category feature blocks provide complete, pre-composed functionality for category management operations in Nodeblocks applications. These features combine schemas, routes, and handlers to create ready-to-use API endpoints for category CRUD operations, status management, and hierarchical organization.

---

🎯 Overview

Category feature blocks are designed to:

• Provide complete category management with full CRUD operations
• Support hierarchical organization with parent-child relationships
• Handle category status management (enable/disable operations)
• Include validation and routing for secure operations
• Support filtering and pagination for category listings

---

📋 Feature Structure

Each category feature follows a consistent composition pattern:

• Schema: Validates category input data and parameters
• Route: Provides HTTP endpoint with category handlers
• Composition: Combines schema and route using compose function

API Endpoint: PUT /api/categories/:categoryId

---

enableCategoryStatusFeatures

Enables disabled categories to restore visibility.

Purpose: Activates category visibility and functionality

Composition:

• Schema: enableCategorySchema - validates path parameters
• Route: enableCategoryRoute - PUT /categories/:id/enable with enable handler

app.use('/api', defService(partial(features.enableCategoryStatusFeatures, [{ dataStores: db }])));

API Endpoint: PUT /api/categories/:categoryId/enable

---

disableCategoryStatusFeatures

Disables enabled categories to hide from listings.

Purpose: Deactivates category visibility and functionality

Composition:

• Schema: disableCategorySchema - validates path parameters
