Serverside Hub Part 2/2 - How To Make A

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)

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 How To Make A Serverside Hub Part 2/2

Use Socket.io (Node.js) or SignalR (.NET). This creates a "persistent pipe" between the hub and the users. When a request hits your hub, the server

Now that your basic server structure is live, it’s time to transform it from a simple gateway into a functional "brain" for your application. 1. State Management & Data Persistence Now that your basic server structure is live,

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.

This second part of our series dives into the of your server-side hub. If Part 1 was about setting the stage (infrastructure and basic routing), Part 2 is about making the gears turn—handling data persistence, real-time synchronization, and security.

A hub is useless if it forgets information the moment a user refreshes. You need a way to store "state"—who is online, what settings are active, and what messages are pending.
