//working with node express many times we find cors issue even though we have installed cors package modules 
//this is the working example using with socket io 

var app = require('express')();
var http = require('http').createServer(app);
var io = require('socket.io')(http,{
	cors:{
		origin:"http://localhost:3000",
		methods: ["GET","POST"],
		allowedHeaders: [""],
		credentials: true
	}
});
const cors = require('cors');

// creating web socket
io.on('connection',(socket)=>{
	console.log('User Online');

	socket.on('canvas-data',(data)=>{
		socket.broadcast.emit('canvas-data',data);
	})
})

// const app= express();
app.use(cors());


var server_port = process.env.YOUR_PORT || process.env.PORT || 5000;
http.listen(server_port,() =>{
	console.log("Started on : "+server_port);
})
// const PORT = 3001;
// app.use(cors());


// app.get("/", (req, res)=>{
// 	res.send("hell of code");
// });

// app.listen(PORT, ()=>{
// 	console.log(`Server running on port ${server_port}`);
// })
