Node.js multiple printing to console without a newline

Question

I have an app for upload files to my server, I am using fs and stream my file to the server and use Chuck data for keep tracking file upload progress.

Here sample code for uploading:

// upload video
function uploadVideo(url,file,callback) {
    let size = fs.lstatSync(file).size;
    let bytes = 0;
    let formData = {
      file: fs.createReadStream(file).on('data', (chunk) => {
        bytes += chunk.length
        process.stdout.write(file+filesize(bytes).human()+' of '+filesize(size).human()+' Uploaded'+"\r")
      }),
    };

    request.post({url:url, json:true, formData: formData}, function optionalCallback(err, httpResponse, body) {
      if (err) {
        return callback('upload failed:', err);
      }
      callback(null,body);
    });

}

as you can see I am using process.stdout.write for showing upload progress without newline and its work fine.

The problem I have when I am uploading multiple files same time, all upload progress get override in one line, I want each upload progress be in separate line.

Multiple upload example:

let files = ['video-1.mp4','video-2.mp4','video-3.mp4','video-4.mp4','video-5.mp4']

// upload multiple file
files.forEach((file) => {
    uploadVideo(url,file,function(err,output){
        console.log(output)
    })
})
