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.

Every request passing through the hub must carry a JSON Web Token (JWT). The hub should verify this token before passing the request to internal services.

Run multiple instances of your hub behind a Load Balancer . How To Make A Serverside Hub Part 2/2

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

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 Use Socket

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.

Use a centralized logger (like Winston or ELK Stack ) so you can see exactly where a packet dropped within the hub's logic. 5. Final Deployment & Scaling The hub should verify this token before passing

As your traffic grows, a single hub instance will become a bottleneck.
