Synapse
Synapse is a robust backend architecture designed for scalable, real-time communication. While it includes a frontend, the core engineering lies in its event-driven backend which leverages Socket.io for sub-millisecond message delivery and Prisma ORM for complex relationship management. The system handles substantial throughput for features like typing indicators, message queues, and media uploads.
Core Technology
System Design
Scalable Real-Time Infrastructure
- •Engineered custom Socket.io adapters for distributed event broadcasting.
- •Optimized database schema with composite indexes for rapid message history retrieval.
- •Implemented secure file handling middleware with stream-processing for media uploads.
Architecture
Event-driven backend architecture. Socket.io handles stateful connections for real-time events, while REST endpoints manage stateless resource operations. Prisma ORM optimizes complex join queries on MySQL to ensure low-latency data retrieval.
Key Features
Real-time bidirectional event streams
Optimized SQL query performance
Secure media stream handling
RBAC middleware implementation
