Azure-Node.js socket.io-Cors

Question

I create a basic nodejs website on azure last days. I would like to have a server dedicate for nodejs, and on the other hand I have a classic HTML5 page on another domain.

The matter is that I have a CORS (cross origin problem) when my page try to connect to the azure website. Any solutions ? This is a bit of my code :

Server :

var express = require('express');
var path = require('path');
var app = express();

var server = require('http').createServer(app).listen(process.env.PORT || 5000);
var io = require('socket.io').listen(server);

Client :

var socket = io.connect('https://****.azurewebsites.net/');

Thanks for your time,

Regards.

From my experience the easiest way to enable CORS is with cors npm package .

Include cors in your package.json or run $ npm install --save cors .

Then include the following in your server code.

var cors = require('cors');
app.use(cors());
