Abstract Class: PersistentCache<B>

Defined in: packages/minerender/src/cache/PersistentCache.ts:10

Key/value store that survives a page reload or process restart.

The concrete backing store is supplied by the active EnvProvider - localforage (IndexedDB) in the browser, node-persist (disk) under Node - so this file itself stays free of any platform-specific import.
