          const socket = new WebSocket('ws://localhost:8080');

          socket.onopen = perform() {
            console.log('Related to the server');
          };

          socket.onmessage = perform(occasion) {
            console.log('Message from the server:', occasion.knowledge);
          };

          socket.ship('Hey from the consumer!');
        
      

        
          const WebSocket = require('ws');

          const server = new WebSocket.Server({ port: 8080 });

          server.on('connection', perform(socket) {
            console.log('New consumer related');

            socket.on('message', perform(message) {
              console.log('Message from the consumer:', message);

              socket.ship('Message from the server: ' + message);
            });
          });
        
      

Integrating Websocket Capabilities
