WebSocket chat application

Most of your favourite apps update themselves with WebSockets , which are persistent connections between your mobile device and the server. Messages can be transmitted in text or binary both ways.

Avoid using WebSockets if only a small number of messages will be sent or if the messaging is very infrequent . Unless the client must quickly receive or act upon updates, maintaining the open connection may be an unnecessary waste of resources.

WebSockets can act as a universal hub for transmitting messages between connected mobile and tablet clients . We can implement a native iOS application, which communicates with a WebSocket server just like the HTML5 JavaScript client.

Additionally, Whatsapp uses HTML5 WebSockets which communication technology which facilitates two-way communication.
