nodejs+websocket case analysis (with code)

This time I will bring you a nodejs websocket case analysis (with code). What are the precautions for nodejs websocket case analysis? The following is a practical case, let’s take a look.

Server (nodejs):

var WebSocketServer = require('ws').Server,
wss = new WebSocketServer({ port: 8080 });
wss.on('connection', function (ws) {
console.log('client connected');
ws.on('message', function (message) {
  console.log(message);
});
});

Client:

<script>
var ws = new WebSocket("ws://localhost:8080");
ws.onopen = function (e) {
  console.log('Connection to server opened');
  sendMessage();
}
function sendMessage() {
  ws.send('hello');
}
</script>
