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

Use Socket.io (Node.js) or SignalR (.NET). This creates a "persistent pipe" between the hub and the users. How To Make A Serverside Hub Part 2/2

Build a mechanism where the hub attempts to re-send failed requests 3 times before giving up. Now that your basic server structure is live,

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. This creates a "persistent pipe" between the hub

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
