FileTransfer vs Transfer to Node

What is the current method of uploading files to a Node server?

I see plenty of examples using FileTransfer and Transfer - which is the way to go now?

I have had no luck with either on the node end, so if anyone has a Current Example - that would be great!

Answering my own here in case anyone else can use it.

Upload function in Ionic2 using Native Transfer:

upload() {
const fileTransfer = new Transfer();
var options: any;

options = {
  fileKey: 'file',
  fileName: 'name.jpg',
  headers: {}

}
let filename = "1085.jpg";  // this is a file in the externalDataDirectory
let uploadFile = cordova.file.externalDataDirectory + filename;
console.log("uploadFile: " + uploadFile)
fileTransfer.upload(uploadFile, "https://yourserver.com:3000/upload", options,)
  .then((data) => {
    console.log("SUCCESS")
  }, (err) => {
    console.log("FAILURE")
  })

}


And in Node:

var storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, './uploads/')
    },
    filename: function (req, file, cb) {
        var datetimestamp = Date.now();
        cb(null, file.fieldname + '-' + datetimestamp + '.' + file.originalname.split('.')[file.originalname.split('.').length -1])
    }
});
var upload = multer({ //multer settings
                storage: storage
            }).single('file');

app.post('/upload', function(req, res) {

    upload(req,res,function(err){
        if(err){
	console.log("ERROR: "+err);
             res.json({error_code:1,err_desc:err});
             return;
        }
console.log("SUCCESS: ");
         res.json({error_code:0,err_desc:null});
    })
});
