Preload map tiles that are outside current map view in Leaflet talks about how to preload map tiles that aren't currently in the viewport but are at the same zoom level. But what if I wanted to preload map all the map tiles for the default map view but at all the various supported zoom levels?
(My use case is that I expect my app to be used in an area where there's no cell service or WiFi; I still want people to be able to pan around and what not in the browser even tho new tiles at various different zoom levels will not be able to be loaded on demand.)
