xray scraper

x(url, {

	poster: '.image img@src',
	videoLink: x('#player@src', 'body script'),	
	
	})
(function (err, obj) {
	if (err) {
		console.log(err);
	}
	else {

		var link = obj.videoLink;
		var lit = /\bpl\b\:'([^']*)/i;

		var scrappedUrl = link.match(lit)[1] || null;
		var output = "";
	
		http.get(scrappedUrl, function (res) {
			res.setEncoding('utf8');
			res.on('data', function (chunk) {
			output += chunk;
		    });
			res.on('end',function(){
				fs.writeFile('../animeApp/app/data/results.json',output);
			});
		});
	};

});
    // .write('../animeApp/app/data/results.json');


this is how i solved the problem with RegExp, but how can i use the .write method instead of "fs"?
