How to create a simple html server using express js

I'm new in node.js I want to create a simple express.js static file server, but I have some issues.
I have been installed express.js 4.2 globally like this:

npm install -g express-generator


I have this code in httpsrv.js:

var http = require('http');
var express = require('express');
var app = express();

app.use('/', express.static(__dirname + '/public'));
app.listen(3000, function() { console.log('listening')});


I'm not sure is it ok I guess it is not enough, but I cant run it it's failed with error: cannot find module 'express'.

I want to create a simple http server which can serve from specific folder("\public" e.g.) and I'm using .html language. I found on the internet a many bullshit, I don't want to use this .jade thing and I don't want to create a empty web app with express etc. I want express.js http server which can operate like Apache and can serve a static html pages first from a specified folder.
Can anybody help me on this, suggest a good article which is explain a step by step, because I'm beginner.

Answer

If you're just trying to serve static files from a directory called "public", you might have luck with an app like this:

var path = require('path');
var express = require('express');

var app = express();

var staticPath = path.join(__dirname, '/public');
app.use(express.static(staticPath));

app.listen(3000, function() {
  console.log('listening');
});

You'll need to make sure Express is installed. You'll probably run npm install express --save in the same directory as the above JavaScript file. Once you're all ready, you'll run node the_name_of_the_file_above.js to start your server.
