WebSocket is a richer protocol to perform bi-directional communication It's a full-duplex communication channel that can operate through a single socket over the web, your request reuses the same connection from the client to the server and the server to the client. The Message event takes place usually when the server sends some data. Messages sent by the server to the client can include plain text messages, binary data, or images. Whenever data is sent, the onmessage function is fired. This event acts as a client's ear to the server. Whenever the server sends.

The Message event takes place usually when the server sends some data. Messages sent by the server to the client can include plain text messages, binary data, or images. Whenever data is sent, the onmessage function is fired.
Websocket Sharp Example
This event acts as a client's ear to the server. Whenever the server sends data, the onmessage event gets fired.
The following code snippet describes opening the connection of Web Socket protocol.
It is also necessary to take into account what kinds of data can be transferred with the help of Web Sockets. Web socket protocol supports text and binary data. In terms of Javascript, text refers to as a string, while binary data is represented like ArrayBuffer.
Web sockets support only one binary format at a time. The declaration of binary data is done explicitly as follows −
Strings
Strings are considered to be useful, dealing with human readable formats such as XML and JSON. Whenever onmessage event is raised, client needs to check the data type and act accordingly.
The code snippet for determining the data type as String is mentioned below −
JSON (JavaScript Object Notation)
It is a lightweight format for transferring human-readable data between the computers. The structure of JSON consists of key-value pairs.
Example
The following code shows how to handle a JSON object and extract its properties −
XML
Parsing in XML is not difficult, though the techniques differ from browser to browser. The best method is to parse using third party library like jQuery.
In both XML and JSON, the server responds as a string, which is being parsed at the client end.
ArrayBuffer
It consists of a structured binary data. The enclosed bits are given in an order so that the position can be easily tracked. ArrayBuffers are handy to store the image files.
Receiving data using ArrayBuffers is fairly simple. The operator instanceOf is used instead of equal operator.
