const patchFile = path.join(__dirname, 'resources/react.patch');
const generatedFile = path.join(__dirname, 'resources/react-generated.zip');

bsdiff.diff(oldFile, newFile, patchFile, function(result, err) {
    if(err) return console.log('Error:', err);
    console.log(result + "%");

    if(result === 100) {
        console.log("Patch");
        bsdiff.patch(oldFile, generatedFile, patchFile, function(result, err) {
            if(err) return console.log('Error:', err)
            console.log(result + "%");
