Testing Node: Uploading a file, see its progress % and creating an equal size .md file

basicNodeFileUpload.js

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

http.createServer(function(request, response){
	
	var newFile = fs.createWriteStream("big_copy.md"); //This is created automatically
	var fileBytes = request.headers['content-length']; //Check how much bytes a file has
	var uploadedBytes = 0;//Keep track of the bytes uploaded.

	request.on('readable', function(){ //Each time information is read 
		var chunk = null;
		while(null !== (chunk = request.read())){ //Reads each request's chunks
			uploadedBytes += chunk.length;
			var progress = (uploadedBytes/fileBytes) * 100; //Calculate upload progress
			response.write("progress: " + parseInt(progress, 10) + "%\n"); //Show it in browser
		}
	});

	request.pipe(newFile); //Takes care of the upload for us...

	request.on('end', function(){
		response.end('File Uploaded!');
	});

}).listen(8080);

--> Test with curl --upload big.mp4 http://localhost:8080 where big.mp4 is a video named like that
--> To run curl command, must be on the container folder, file must name as in command and check copied file at the end
--> It only works with .md files
