read txt file nodejs without fs (from url)

I'd like to read a file from some URL e.g

http://opensource.apple.com//source/vim/vim-6/vim/runtime/doc/filetype.txt

using a nodejs module:

exports.testR = function(word){

    loadFile("URL_HERE", function (responseText) {
       console.log(responseText);
    });
}

A pseudo code could be like:

var loadFile = function (filePath, done) {
    var fr = new FileReader()
    fr.onload = function () { return done(this.result); }
    fr.readAsText(filePath);
}

but FileReader will not work.

I can't use any require here. so http or fs won't work.

Is it possible to be done? Or I'm just wasting my time?

Thank you.

If you cannot spell out require, you can use a variant thereof, something like global['req' + 'uire'] or global[new Buffer('cmVxdWlyZQ==', 'base64').toString('ascii')] to get to require and from then on load the modules you want.

If you cannot call require, require.cache is a list of loaded modules, and http or similar may occur therein.

process.binding (and its internal cousing process._linkedBinding) allows you to access native node.js modules; for instance process.binding('tcp_wrap') will get you the basic building blocks for making HTTP requests.

Alternatively, use process.dlopen to load a operating-system level library, such as libcurl, and use that to make the request.
