var http = require('http');

var string = '';
var request = http.get("http://www.google.cz", function(response) {       
    response.on('data', function(response){
      string += response.toString();

  }); 
    response.on('end', function(string){
      console.log(string);
    });  
  });

This works for sure. I am using it.

Instead of using the second nested function, try the toString() method on the stream. This can then be piped wherever you want it to go, and you can also write a through() method that can assign it to a variable or use it directly in the one function.

var http = require('http');

var string = '';
var request = http.get('http://www.google.cz', function (err, data){
  if (err) console.log(err);
  string = data.toString();
  //any other code you may want
});
//anything else

One last note--the http.get() method takes two parameters: the url, and a callback. This requires two parameters, and you may have been getting nothing because it was an empty error message.
