Web Socket

Websocket is used to broadcast new publish news. WebSocket address is : ws://localhost:8080/newssocket. Here is sample script on client when consum a websocket. Create a file client.html on your document root and open it using your favorite browser : http://localhost/client.html

<script>
var ws = new WebSocket("ws://localhost:8080/newssocket");

ws.onopen = function() {
  ws.send("hello server!")
}

ws.onmessage = function(event) {
  var m = event.data;
  if (m === "pong") console.debug("Received message", m);
  else notifyMe(m);
}

ws.onerror = function(event) {
  console.debug(event)
}

function notifyMe(message) {
  // Let's check if the browser supports notifications
  if (!("Notification" in window)) {
    alert("This browser does not support system notifications");
  }

  // Let's check whether notification permissions have already been granted
  else if (Notification.permission === "granted") {
    // If it's okay let's create a notification
    var notification = new Notification(message);
  }

  // Otherwise, we need to ask the user for permission
  else if (Notification.permission !== 'denied') {
    Notification.requestPermission(function (permission) {
      // If the user accepts, let's create a notification
      if (permission === "granted") {
        var notification = new Notification(message);
      }
    });
  }

  // Finally, if the user has denied notifications and you 
  // want to be respectful there is no need to bother them any more.
}
</script>
