how to run node.js app from cmd with some predefined port in Windows

Is it some command exist to run my node.js code with directly specified port? something like node server.js port=7777 ?

my server.js code looks like this

http.createServer(function (req, res) {
  if (mount(req, res)) return;
}).listen(process.env.PORT || 80);

http-server -p 7777

for linux export PORT=5000; node index.js

for windows set PORT=5000; node index.js

in case of powerShell

set $env:PORT=5000; node index.js

const port = process.env.PORT || 3000; app.listen(port,()=>{console.log(Listening on port ${port})})

A simple adding to Alberto's answer. On Windows machine you haven't export command in cmd, use set instead. Then the whole script will be looks like this:

set PORT=7777
node server.js

Note that the syntax in PowerShell is slightly different:

$env:PORT=7777
node server.js

Depending on what server.js contains you should be able to do so.

At a minimum you should read port (you could use https://github.com/substack/node-optimist)

var argv = require('optimist').argv;
console.log(argv.port);

// use it like this
$ node server.js -port 7777

and then listen to it on your server (this depends on what lib you're using).

Run the server like this

export PORT=7777; node server.js
