// The prescribed way of doing this import would be:
//import {IndexedDbStoreWorker} from 'matrix-js-sdk';
// However, this still pulls in all of the js-sdk and we only use a tiny fraction
// of it. It also causes an Olm error to appear because we don't have an Olm in scope.
// Instead, we do this:
import IndexedDBStoreWorker from 'matrix-js-sdk/lib/store/indexeddb-store-worker';

const remoteWorker = new IndexedDBStoreWorker(postMessage);

onmessage = remoteWorker.onMessage;
