Real-time collaborative applications require persistent, bi-directional connections between clients and servers. Here is how we build real-time collaborative platforms.
1. Implementing Socket.io Gateways
We deploy Socket.io gateways in Node.js to manage active WebSocket channels, routing events (like text updates or mouse cursor tracking coordinates) in real-time.
2. Horizontal Scaling with Redis Adapters
To scale WebSockets across multiple server nodes, we integrate Redis Adapter streams. The adapter pub-sub broker broadcasts events across all nodes, syncing active sessions automatically.
Conclusion
Building socket-driven architectures enables real-time collaboration. By combining Socket.io with scaling adapters, we ensure fast synchronization at scale.
