Node.JS static file web server. Put it in your path to fire up servers in any directory, takes an optional port argument.

static_server.js

var http = require("http"),
    url = require("url"),
    path = require("path"),
    fs = require("fs")
    port = process.argv[2] || 8888;

http.createServer(function(request, response) {

  var uri = url.parse(request.url).pathname
    , filename = path.join(process.cwd(), uri);
  
  path.exists(filename, function(exists) {
    if(!exists) {
      response.writeHead(404, {"Content-Type": "text/plain"});
      response.write("404 Not Found\n");
      response.end();
      return;
    }

    if (fs.statSync(filename).isDirectory()) filename += '/index.html';

    fs.readFile(filename, "binary", function(err, file) {
      if(err) {        
        response.writeHead(500, {"Content-Type": "text/plain"});
        response.write(err + "\n");
        response.end();
        return;
      }

      response.writeHead(200);
      response.write(file, "binary");
      response.end();
    });
  });
}).listen(parseInt(port, 10));

console.log("Static file server running at\n  => http://localhost:" + port + "/\nCTRL + C to shutdown");

Agree with the last comment, replacing path.exist with fs.exist fixed an error that I did not fully understand. Otherwise, fantastic solution, perfect for beginners :)

yes thanks brandt1871 path.exists is now called fs.exists

Same issue here, path.exists is now called fs.exists

Please fix for future generations :)

Thanks!!!

Please, include package.json so that we could npm install. Thanks!

You saved my day brotha.. Thanks :) ~

For those newbies out there, path.exists has been depricated to fs.exists.

thank u

If anyone is interested in ES6+ version, I've revamped it here.

Small typo: fs = require("fs") is missing a comma at the end of the line, making port on the next line a global variable.
Thank you for sharing!

Fixed the whole code. Enjoy :)

var http = require("http"),
    url = require("url"),

Hi, Everyone:

Problem: There is a failure in the JavaScript code (server.js) to route a var to the following directory: ./public/index.html.

Symptoms: HTTP Error 403.14 - Forbidden.

Request for Support: What is the correct JavaScript to route var to a particular directory?

I created a new one that handles MIME types and uses ES6+

Got an error with path.exists, changed it to fs.exists and the snippet worked fine.

@kovid-rathee I ran in to the same issue and your solution worked!

Hey, guys what do you think about this article?
he best Node.js framework for your project: Express.js, Koa.js or Sails.js is express js the best framework for Node js?

Awesome! I am new to Node.js and was trying to figure out how to configure this...This worked with a minor update as givne in another post creationix/howtonode.org#88
Thank you very much!

ty. min req, what i was after

path.exists has been deprecated. If you want a sync check then

  if (!fs.statSync(filename)) {
    response.writeHead(404, {'Content-Type': 'text/plain'})
    response.write('404 Not Found\n')
    response.end()
    return
  }

even better how about the handler's fs stuff all async with callbacks

fs.stat(filename, function(err,stats) {
    if (err) {
      response.writeHead(404, {'Content-Type': 'text/plain'})
      response.write('404 Not Found\n')
      response.end()
      return
    }

    if (stats.isDirectory()) filename += '/index.html'

    fs.readFile(filename, 'binary', function(err, file) {
      if(err) {
        response.writeHead(500, {'Content-Type': 'text/plain'})
        response.write(err + '\n')
        response.end()
        return
      }
      response.writeHead(200)
      response.write(file, 'binary')
      response.end()
    })
  })

Thanks a lot :)

Thanks a lot, but it can be hijacked

This is insecure, someone can request /../../../etc/shadow or similar to read any file they want.

thanks ...it's great, that why I'm looking for it

path.exists is now called fs.exists

This is insecure, someone can request /../../../etc/shadow or similar to read any file they want.

I guess you're not familiar with how path.join works, because as coded here it won't resolve to a directory outside of cwd directory branch.

fs.exists is deprecated. fs.statSync can be used to check if file path exists, as in dkebler's code above.

Thank you for this!

Incredible article, thanks for sharing it! I think this article will also be useful for you - Node js vs Python.
