Offline map in ionic (react) / react?

[borakuldeep]

Hello, Great repo. If you are familiar with ionic, could you please share your thought on how to implement offline maps in ionic latest version? The offline should work across all platforms (web/mobile/native).
I am using react for ionic.
Can't find your email, that;s why mentioning this here.

Hi, unfortunately I don't familiar with ionic.

A few ideas, that should works in general (not related to framework you choose):

• static files as html/js/css/sprites should have no issues with going offline
• most issue you can have with tile data caching
• if you can deliver and manage tile data within application, sound this way can be better
• if you cannot deliver (using web page that can go offline), then you can do something similar to this repo (use storages available in browser and override way to fetch tiles)
• you probably want to decrease area you want to cache to decrease cache data size
• you probably want to decrease max zoom you want to cache to decrease cache data size
• you probably want to use vector tiles instead raster to decrease cache data size
• you probably want to use vector tiles with only necessary features to decrease cache data size
