We are considering using react-native-svg in our app. We are a bit tempted to use it liberally around the app to create pretty much the visuals of every page, since it should scale better than using images. We are targeting both Android and iOS, tablets and phones.
Does it make sense to make heavy use of SVGs around the app with react-native-svg instead of using PNG images?
IMHO, you should not. I had to deal with svgs a lot of time, and it was always way more complex than pure PNG. If you have to draw icons on tabs or on menus, use PNG, PNG@2x, PNG@3x. react-native-svg can be useful for remote SVG loading, like content managed in a back-office.
