Using WebSocket subscriptions without queues

In a world increasingly reliant on real-time data communication, WebSockets offer a robust solution for establishing full-duplex, low-overhead connections between servers and clients, allowing both parties to send messages anytime during the connection. This is particularly useful in applications like multiplayer games, live financial updates, and online chat platforms. The implementation of WebSockets involves setting up a connection through an HTTP protocol upgrade, followed by maintaining communication via the WebSocket Protocol. The process is made easier with JavaScript's event loop for managing asynchronous events, simplifying error handling, retries, and connection management. By adopting a lazy connection approach, connections are established only when necessary and closed when no longer needed, enhancing efficiency. The article also highlights the use of a subscription system to manage message dispatching and error handling, ultimately creating a resilient client-side implementation that can be easily extended to server-side applications.
