Discord Bot Ecosystem: Multi-Service API Gateway

Multi-Service API Gateway Architecture

TypeScript-based Discord bot serving as central API gateway with Express.js server, GitHub webhook processing, and custom endpoint management for cross-platform automation.

---

Technical Architecture

• Express.js Server - REST API with JWT authentication and middleware stack
• Discord.js Integration - Slash commands, modal interactions, and embed generation
• GitHub Webhook Processing - Signature validation and commit payload parsing
• Custom API Endpoints - Raspberry Pi hardware integration and notification system

---

Core Technical Implementation

API Gateway Structure

• Express.js server with modular route handlers
• JWT token validation for secure cross-service communication
• Webhook signature verification using SHA-256 hashing
• Rate limiting via token bucket algorithm

GitHub Integration

• Webhook payload parsing with type-safe TypeScript interfaces
• Commit message analysis using regex patterns and semantic extraction
• Dynamic embed generation with Discord.js MessageEmbed builder
• File change detection and diff summarization algorithms

Discord Bot Features

• Slash command registry with permission-based routing
• Modal interactions for complex user input handling
• Embed template system with conditional field rendering
• Event-driven architecture using Discord.js event emitters

Performance & Optimization

• Connection pooling for multiple API endpoints
• Memory-efficient stream processing for large payloads
• Atomic file I/O operations for state persistence
• Background garbage collection and memory management
