Is WebSocket better than polling?

WebSockets keeps a unique connection open while eliminating the latency problems that arise with long polling. Full-duplex asynchronous messaging is supported so that both the client and the server can stream messages to each other independently.

How long can a WebSocket stay open?

However, the connection between a client and your WebSocket app closes when no traffic is sent between them for 60 seconds.

How do long polling and WebSocket compare?

WebSockets are Full-Duplex meaning both the client and the server can send and receive messages across the channel. Long Polling is Half-Duplex meaning that a new request-response cycle is required each time the client wants to communicate something to the server.

How does HTTP long polling work?

HTTP Long polling is a mechanism where the server can send data independently or push data to the client without the web client making a request. The information is then pushed as it becomes available, which makes it real-time. However, it works best if the messages from the server are rare and not too frequent.
