🚀 Chat Feature Blocks

Chat feature blocks provide complete, pre-composed functionality for chat management operations in Nodeblocks applications. These features combine schemas, routes, and handlers to create ready-to-use API endpoints with proper validation, authentication, and error handling.

---

🎯 Overview

Chat feature blocks are designed to:

• Provide complete API endpoints for chat management operations
• Combine schemas with routes for validated operations
• Include authentication and authorization checks automatically
• Support functional composition patterns
• Handle logging and error management seamlessly

This documentation is organized into three main subsections:

• 📺 Channel Features: Manage chat channels (create, read, update, delete, search)
• 💬 Message Features: Handle chat messages (create, read, update, delete, search)
• 🔔 Subscription Features: Manage user subscriptions to channels (create, read, delete, search)

---

📋 Feature Structure

Each chat feature follows a consistent composition pattern:

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