I'm developing a very simple angular app for a tournament were we want to administrate some statistics for the contestants. So far to so good and have it develop with angular and firebase.
Now I want to use picture for the contestants scale it down before converting to Base64 and finally upload it to firebase. I'm using on site my smartphone to take picture from the contestants.
My question is how to scala the down the picture taken by the smartphone down to as small as it possible to see the face and minimise the usage of 3g/4g for my and the user on site.
do you have some experience with that kind of situation? And is this a ok for Firebase to taka long string (I'm quite new to Firebase services)?
