Auto cleanup (LRU) about app-storage HOT 3 CLOSED

LocalStorage doesn't keep any built-in indication of create / update time. It's possible to keep track of this yourself by recording such values with your data as you change it, but it can be costly to constantly deserialize and re-examine values that are kept in LocalStorage.

app-localstorage-document does nothing to improve this condition, nor does it make anything harder than it would be when using the basic Storage API.

app-indexeddb-mirror uses IndexedDB as its backing storage layer. This presents an opportunity to index and query by age of record in order to purge old entries. Currently, app-indexeddb-mirror does not do this. However, if someone could describe the user story in an issue, we may be able to design a feature of app-indexeddb-mirror that supports automatic purging of old data.

So, bottom line: app-storage doesn't do anything to help or hurt this specific use case today. In some cases, it might be able to help in the future. For LocalStorage: I would advise against trying to keep lots of structured data there.

In case somebody else faces the same issue, we implemented and open sourced an element that allows pruning old entries in local storage:
