import { initDB } from "@frecency/indexeddb-datasource";

const datasource = initDB("unique-identitier-used-as-name-of-database");

await datasource.visit("namespace.selector", "contoso");
await datasource.visit("namespace.selector", "contoso");

await datasource.visit("namespace.selector", "acme");
await datasource.visit("namespace.selector", "contoso");
await datasource.visit("namespace.selector", "contoso");

// Results are returned ordered by their score
const list = await datasource.list("namespace.selector");
