Based on  epegzz suggestion for the regex     url     gt      return url match           0  split      slice 1      returns an array with paths

req protocol           req get  host     req originalUrl   or  req protocol           req headers host   req originalUrl    I like this one as it survives from proxy server  getting the original host name

var http   require  http    var url    require  url    var fs     require  fs     var neededstats        http createServer function req  res        if  req url      index html     req url                   fs readFile    index html   function err  data                res end data                     else           var p     dirname         req params filepath          fs stat p  function err  stats                if  err                    throw err                            neededstats push stats mtime               neededstats push stats size               res send neededstats                        listen 8080   0 0 0 0    console log  Server running       I have not tested your code but other things works  If you want to get the path info from request url   var url parts   url parse req url    console log url parts    console log url parts pathname     1 If you are getting the URL parameters still not able to read the file just correct your file path in my example  If you place index html in same directory as server code it would work     2 if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs  If you want raw solution to file path  var http   require  http    var url   require  url     function start     function onRequest request  response        var pathname   url parse request url  pathname      console log  Request for     pathname     received         response writeHead 200    Content-Type    text plain         response write  Hello World        response end       http createServer onRequest  listen 8888   console log  Server has started        exports start   start    source   http   www nodebeginner org
