Usage

First, you need to provide your local and remote stores to be used, being possible to use any Keyv storage adapter:

import Keyv from 'keyv';
import KeyvTiered from '@keyv/tiered';
import KeyvSqlite from '@keyv/sqlite';

const remoteStore = () => new Keyv({
	store: new KeyvSqlite({
		uri: 'sqlite://test/testdb.sqlite',
		busyTimeout: 30_000,
	}),
});
const localStore = () => new Keyv();
const remote = remoteStore();
const local = localStore();
const store = new KeyvTiered({remote, local});
const keyv = new Keyv({store});
keyv.on('error', handleConnectionError);
