How to download a file with Node.js (without using third-party libraries)?

How do I download a file with Node.js without using third-party libraries?

I don't need anything special. I only want to download a file from a given URL, and then save it to a given directory.

You can create an HTTP GET request and pipe its response into a writable file stream:

var http = require('http');
var fs = require('fs');

var file = fs.createWriteStream("file.jpg");
var request = http.get("", function(response) {

If you want to support gathering information on the command line--like specifying a target file or directory, or URL--check out something like Commander.
