Here's how it's done

function uploadFile(){
    var path = untildify("~/workspace/a.jpg");
    var drive = google.drive('v2');
    console.log('start upload');
    var req = drive.files.insert({
        resource: {
            title: "a.jpg"
        },
        media: {
            body: fs.createReadStream(path)
        },
        auth: oauth2Client
    }, function(err, response, body) {
        if (err) {
            console.log(err);
        } else {
            console.log('finish upload');
            clearInterval(q);
        }
    });
    var q = setInterval(function () {
         console.log("Uploaded: " + req.req.connection.bytesWritten);
     }, 250);
}
