In developing a Progressive Web App (PWA) is it possible to store cached files online for offline access to ensure that the application continues to function while at the same time saving on bandwidth?
Well, it is possible to save images or files in a certain encoding as base 64 in WebStorage. However, in my searches it seems that the limit is approximately 20 MB per source depending on the Browser.
In an assumption where the user wants to watch or listen to a content later, what would be the best way to manage it (save, update, delete ...) on the user's device? It's possible? Or is PWA no longer holding 20% or 30% of the benefits of a native App?
