Hi Guys , How do you handle caching in shared kmm modules ?

[Paul Weber]

That’s an extremely broad question.
What kind of data do you want to cache and for what reasons?

Because this can be as complicated or simple as you want it to be.

I want to have caching of a list of objects and display them in case the user is offline

[John O'Reilly]

There's a range of caching/persistence libraries available for KMM.... https://github.com/cashapp/sqldelight is probably most popular.....depending on data you want to store the following might also be sufficient https://github.com/russhwolf/multiplatform-settings

[Paul Weber]

Either put them in a database (SQLDelight, Realm, MongoDB, etc), store them in SharedPreferences / UserDefaults (there’s a KMM wrapper around these if you don’t want to write your own) or serialize them to files on disk.

So, basically as you would in native code as well

Thank you guys

Also I suppose there may be some alternatives depending of your other dependencies and your needs, I'm thinking about network cache, Apollo GraphQL cache, ... (never tested myself)

I would argue for this last one. Coil has an image cache. Apollo GraphQL has a data aware cache. HTTP libraries will have a smart cache also, that should be able to server stale content if configured correctly. Often simpler than writing your own persistence.
