What is the method of using websockets?

Here is the way to use WebSocket:

1. Create a WebSocket object: Use the WebSocket class in JavaScript to create a WebSocket object. The server’s URL needs to be passed in as a parameter.
2. Create a new WebSocket connection to “ws://example.com/socket” and assign it to the variable named “socket”.
3. Event listening: You can monitor the status of a WebSocket and receive messages through the events of the WebSocket object.
4. onopen: Triggered when the WebSocket connection has been established.
5. onmessage: triggers when a message is received from the server.
6. onclose: triggered when the WebSocket connection is closed.
7. onerror: Triggered when there is an error with the WebSocket connection.
8. “Can you please explain the difference between these two concepts?”

   “Could you clarify the distinction between these two ideas?”

9. socket.onopen = function() {
   console.log(“WebSocket connection successfully established”);
   };

   socket.onmessage = function(event) {
   var message = event.data;
   console.log(“Message received: ” + message);
   };

   socket.onclose = function() {
   console.log(“WebSocket connection closed”);
   };

   socket.onerror = function(error) {
   console.error(“WebSocket connection error: ” + error);
   };

10. Send message: You can utilize the send() method of the WebSocket object to transmit messages to the server.
11. Send the message “Hello, server!” using the socket.
12. Note: Messages can be either text data or binary data.
13. Close connection: you can actively close the WebSocket connection using the close() method of the WebSocket object.
14. Close the socket.
15. Please note that WebSocket connections can also be closed on the server side, in which case the client will trigger the onclose event.

The above is the basic usage of WebSockets. Developers can use WebSockets for real-time communication or to implement other features according to their specific needs.
