how to run different node app on server different domains


var http = require('http'),
httpProxy = require('http-proxy');

var proxy_web = new httpProxy.createProxyServer({
target: {
host: 'localhost',
port: 8080
}
});

var proxy_api = new httpProxy.createProxyServer({
target: {
host: 'localhost',
port: 8081
}
});

http.createServer(function(req, res) {
if (req.headers.host === 'http://www.domain.com') {
proxy_web.proxyRequest(req, res);
proxy_web.on('error', function(err, req, res) {
if (err) console.log(err);
res.writeHead(500);
res.end('Oops, something went very wrong...');
});
} else if (req.headers.host === 'http://api.domain.com') {
proxy_api.proxyRequest(req, res);
proxy_api.on('error', function(err, req, res) {
if (err) console.log(err);
res.writeHead(500);
res.end('Oops, something went very wrong...');
});
}
}).listen(80);
