Hello, I tried to get GPS location from photo. but it is not working

I am now developing social photo sharing platform using ionic.
The most important feature is to get GPS location from taken photo.
I’ve tried several times but always get failure to integrate exif js on my app.
I referred those links.

Is there anyone to have experiences of integrate exif js?
please leave any though if you have exp.
Welcome any opinions!
