Purpose

This repository serves as a reference implementation for building scalable event-driven systems using various technologies and architectural patterns. Each module contains working examples, best practices, and documentation specific to its domain.

Quick Start

1. Clone the repository:

   git clone https://github.com/satya-supercluster/event-systems.git
   cd event-systems

2. Navigate to any module to explore implementations:

   cd api/graphql
   cat README.md

3. Each module contains its own README with specific setup instructions and examples.

Module Overview

API Layer

• GraphQL: Real-time data subscriptions and efficient query handling
• REST: Traditional RESTful endpoints with event notifications
• Webhooks: Event-driven HTTP callbacks for asynchronous processing

Real-time Communication

• WebSocket: Full-duplex communication channels for live updates
• WebRTC: Direct peer-to-peer connections for low-latency streaming

RPC Systems

• gRPC: High-performance RPC with Protocol Buffers
• RPC: Various RPC implementations and patterns

Message-Oriented Middleware

• Kafka: Distributed streaming platform for high-throughput event processing
• Pub/Sub: Publish-subscribe messaging for decoupled service communication
• Message Queue: Asynchronous message queuing for reliable delivery

Caching & Data

• Redis: In-memory caching, pub/sub, and stream processing

Infrastructure

• Nginx: Reverse proxy, load balancing, and SSL termination
• SSH: Secure tunneling and remote access configurations

Common Resources

• Configs: Shared environment variables and settings
• Scripts: Automation tools for testing and deployment
• Docs: Architecture diagrams, design patterns, and additional guides
