How to integrate nodeJS + Socket.IO and PHP?

Question

I have recently been looking around, to find a good way to communicate between nodeJS and PHP. Here is the idea : nodeJS is still quite new, and it can be kind of tricky to

Answer 1

Try similar or you can check my blog for complete sample code on nodejs

On your page side:

• Load Socket JS

https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.js

• Make object of the socket

var socket = io();

• Use the emit function to send data to nodeserver.

socket.emit('new_notification', {
message: 'message',
title: 'title',
icon: 'icon',
});

So now your code will be look like

var socket = io(); 

$(document).ready(function($) {
  $('.rules-table').on('click', '.runRule', function(event) {
    event.preventDefault();
    /* Act on the event */
    var ruleID = $(this).parents('tr').attr('id');

    // send notification before going to post 
    socket.emit('new_notification', {
        message: 'Messge is ready to sent',
        title: title,
        icon: icon,
    });
    $.ajax({
      url: '/ajax/run-rule.php',
      type: 'POST',
      dataType: 'json',
      data: {
        ruleID: ruleID
      },
    })
    .done(function(data) {
      console.log(data);

      // send notification when post success 
      socket.emit('new_notification', {
        message: 'Messge was sent',
        title: title,
        icon: icon,
      });

    })
    .fail(function() {
      console.log("error");

      // send notification when post failed 
      socket.emit('new_notification', {
        message: 'Messge was failed',
        title: title,
        icon: icon,
      });
    })
    .always(function() {
      console.log("complete");
    });

  });
});

Now on Node server side make handler for your request to get your request and send a message to all connected devices/browsers(server.js)

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res) {
   res.sendfile('index.html');
});


io.on('connection', function (socket) {
  socket.on( 'new_notification', function( data ) {
    console.log(data.title,data.message);

    // Now Emit this message to all connected devices
    io.sockets.emit( 'show_notification', { 
      title: data.title, 
      message: data.message, 
      icon: data.icon, 
    });
  });
});

http.listen(3000, function() {
   console.log('listening on localhost:3000');
});

Now the client/browser/client side make a receiver to receive socket message from node server

   

var socket = io();

/**
 * Set Default Socket For Show Notification
 * @param {type} data
 * @returns {undefined}
 */
socket.on('show_notification', function (data) {
    showDesktopNotification(data.title, data.message, data.icon);
});
/**
 * Set Notification Request
 * @type type
 */
function setNotification() {
    showDesktopNotification('Lokesh', 'Desktop Notification..!', '/index.jpeg');
    sendNodeNotification('Lokesh', 'Browser Notification..!', '/index.jpeg');
}
/**
 * Check Browser Notification Permission
 * @type window.Notification|Window.Notification|window.webkitNotification|Window.webkitNotification|Window.mozNotification|window.mozNotification
 */
var Notification = window.Notification || window.mozNotification || window.webkitNotification;
Notification.requestPermission(function (permission) {
});
/**
 * Request Browser Notification Permission 
 * @type Arguments
 */
function requestNotificationPermissions() {
    if (Notification.permission !== 'denied') {
        Notification.requestPermission(function (permission) {
        });
    }
}
/**
 * Show Desktop Notification If Notification Allow
 * @param {type} title
 * @param {type} message
 * @param {type} icon
 * @returns {undefined}
 */
function showDesktopNotification(message, body, icon, sound, timeout) {
    if (!timeout) {
        timeout = 4000;
    }
    requestNotificationPermissions();
    var instance = new Notification(
            message, {
                body: body,
                icon: icon,
                sound: sound
            }
    );
    instance.onclick = function () {
        // Something to do
    };
    instance.onerror = function () {
        // Something to do
    };
    instance.onshow = function () {
        // Something to do
    };
    instance.onclose = function () {
        // Something to do
    };
    if (sound)
    {
        instance.sound;
    }
    setTimeout(instance.close.bind(instance), timeout);
    return false;
}
