How to run server on node?

Question

JavaScript

I did exactly as it says here , I also did node.jsnpm install node-static after installation , created server.js and wrote into it:

var http = require('http');
var static = require('node-static');
var file = new static.Server('.');

http.createServer(function(req, res) {
  file.serve(req, res);
}).listen(3000);

console.log('Server running on port 3000')

I start the server node url ... server.js and in cmd it is written that
server running port 3000

Answer 3

On learn.javascript.ru it is written to check like this:
3. Open 127.0.0.1:8080/server.js in the browser.
Should output the server.js file code.
You need to put some file in the current folder and add it to the path in the browser.
