Cache images coming from Firebase Storage


#1

I would like to cache image coming from Firebase Storage but the info online is a bit confusing. A lot of tutorials show the use of Cordova File and Cordova File Transfer. Why not ionic/storage and save the image in base64 using btoa()? Note that the CORS issue from Firebase exists and this is the only way to get around it: https://stackoverflow.com/questions/37760695/firebase-storage-and-access-control-allow-origin/37765371#37765371. Is it possible to cache image from Firebase Storage for apps running in the browser, iOS and Android? Anyone handled this issue?

This is my ionic info.

Can we use updateMetaData() for cache: https://firebase.google.com/docs/storage/web/file-metadata

Check out https://firebase.google.com/docs/storage/web/file-metadata. You can set a cache header for the file.
