node.js - Making xampp and node(socket.io) work together -

i have little web app applies angularjs , php functions , queries database(xampp's apache , mysql). want apply simple chat in web app , not know how configure nor ports , on.

following similar http://socket.io/get-started/chat/

i have index.js such

var app = require('express')(); var http = require('http').server(app); var io = require('socket.io')(http);  app.get('/', function(req, res){    res.sendfile(__dirname + '/index.html');  });  io.on('connection', function(socket){    console.log('a user connected');    socket.on('disconnect', function(){    console.log('user disconnected');    }); });   http.listen(443, function(){   console.log('listening on *:443'); }); 

i trying port 443 , 80, doesnt seem work (xampp shows 80 , 443, no idea how ports work)

my js file has var socket = io();

in browser console , i'm getting

socket.io-1.2.0.js:2 http://localhost/socket.io/?io=3&transport=polling&t=1465649664392-0 404 (not found) 

how resolve problem? expecting output such a user connected in cmd after running node index.js not.

i followed example chat, , works fine without xampp.

your problem socket.io work needs able communicate end on http (e.g. switch protocol). if xampp using port won't work. try xampp forwards requests http://localhost/socket.io/* node.js server.

you can use proxypass directive in apache httpd.conf , like

rewriteengine on rewritecond %{request_uri}  ^/socket.io            [nc] rewritecond %{query_string} transport=websocket    [nc] rewriterule /(.*)           ws://localhost:8000/$1 [p,l]  proxypass        /socket.io http://localhost:8000/socket.io proxypassreverse /socket.io http://localhost:8000/socket.io 

also make sure required modules enabled

loadmodule proxy_module modules/mod_proxy.so loadmodule proxy_http_module modules/mod_proxy_http.so loadmodule proxy_wstunnel_module modules/mod_proxy_wstunnel.so 

then you'd have start node.js server on port 8000

http.listen(8000, function(){   console.log('listening on *:8000'); });
