@ngx-pwa/local-storage/bundles/ngx-pwa-local-storage.umd.min.js

Efficient local storage module for Angular: simple API based on native localStorage API, but internally stored via the asynchronous IndexedDB API for performance, and wrapped in RxJS observables to be homogeneous with other Angular modules.
