Although its hidden we can still capture the event when an image was selected, which will as a result upload that file using our service!

So, we are using our own Grails 3 applicationas the file server for this tutorial. We are not uploading a base64 string, we are uploading a blob to the storage. Multer will handle the streams of data provided by busboy for us, and automatically upload the file to a specified destination on the server. I hope you liked this tutorial and share it with others.
