Does anyone have a tip if this can be done and how I can do this ?
var fs= require("fs");
var stream= require("stream");
var util= require("util");
var inFile= fs.createReadStream("in.txt", {encoding: "utf8"});
var outFile= fs.createWriteStream("out.txt");
var UpperTransform = function(options) {

util.inherits(UpperTransform, stream.Transform);
UpperTransform.prototype._transform = function(line, enc, done) {

};
var upper = new UpperTransform({ objectMode: true });
upper.on("error", function(err) {
console.log(err)
});
inFile.pipe(upper).pipe(outFile);
Enjoy !
