Hub Part 2/2: How To Make A Serverside

Most hubs require instant updates (think dashboards or chat). Standard HTTP requests won't cut it because the server can't "talk" to the client unless asked.

How to Build a Server-Side Hub (Part 2/2): Logic & Execution How To Make A Serverside Hub Part 2/2

If you are using WebSockets, ensure your load balancer supports "sticky sessions" so a user stays connected to the same hub instance during their session. Conclusion Most hubs require instant updates (think dashboards or chat)

Start by implementing a simple Redis cache to see how much it improves your hub’s response times! Conclusion Start by implementing a simple Redis cache

Build a mechanism where the hub attempts to re-send failed requests 3 times before giving up.

When a request hits your hub, the server should check the cache (Redis) first. If the data isn't there, fetch it from the main DB and update the cache for next time. 2. Real-Time Synchronization (WebSockets)

Run multiple instances of your hub behind a Load Balancer .
