Once you have one, you can easily set <a href="https://tinybase.org/api/store/type-aliases/store/values/"><code>Values</code></a> in it by unique <a href="https://tinybase.org/api/common/type-aliases/identity/id/"><code>Id</code></a>. And of course you can easily get them back out again.</p><p>Read more about using keyed value data in <a href="https://tinybase.org/guides/the-basics/">The Basics</a> guide.</p></section>

```js
const store = createStore()
  .setValues({employees: 3})
  .setValue('open', true);

console.log(store.getValues());
// -> {employees: 3, open: true}
```

<section><h2 id="level-up-to-use-tabular-data">Level up to use tabular data.</h2><p>For other types of data applications, a tabular data structure is more useful. TinyBase lets you set and get nested <a href="https://tinybase.org/api/store/type-aliases/store/table/"><code>Table</code></a>, <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a>, or <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a> data, by unique <a href="https://tinybase.org/api/common/type-aliases/identity/id/"><code>Id</code></a> and in the same <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a> as the keyed values.</p><p>Read more about setting and changing data in <a href="https://tinybase.org/guides/the-basics/">The Basics</a> guide.</p></section>

```js
store
  .setTable('pets', {fido: {species: 'dog'}})
  .setCell('pets', 'fido', 'color', 'brown');

console.log(store.getRow('pets', 'fido'));
// -> {species: 'dog', color: 'brown'}
```

<section><h2 id="register-listeners-at-any-granularity">Register listeners at any granularity.</h2><p>The magic starts to happen when you register listeners on a <a href="https://tinybase.org/api/store/type-aliases/store/value/"><code>Value</code></a>, <a href="https://tinybase.org/api/store/type-aliases/store/table/"><code>Table</code></a>, <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a>, or <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a>. They get called when any part of that object changes. You can also use wildcards - useful when you don&#x27;t know the <a href="https://tinybase.org/api/common/type-aliases/identity/id/"><code>Id</code></a> of the objects that might change.</p><p>Read more about listeners in the <a href="https://tinybase.org/guides/the-basics/listening-to-stores/">Listening To Stores</a> guide.</p></section>

```js
const listenerId = store.addTableListener('pets', () =>
  console.log('changed'),
);

store.setCell('pets', 'fido', 'sold', false);
// -> 'changed'

store.delListener(listenerId);
```

<section><h2 id="call-hooks-to-bind-to-data">Call hooks to bind to data.</h2><p>If you&#x27;re using React in your application, the optional <a href="https://tinybase.org/api/ui-react/"><code>ui-react</code></a> module provides hooks to bind to the data in a <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a>.</p><p>More magic! The <a href="https://tinybase.org/api/ui-react/functions/store-hooks/usecell/"><code>useCell</code></a> hook in this example fetches the dog&#x27;s color. But it also registers a listener on that cell that will fire and re-render the component whenever the value changes.</p><p>Basically you simply describe what data you want in your user interface and TinyBase will take care of the whole lifecycle of updating it for you.</p><p>Read more about the using hooks in the <a href="https://tinybase.org/guides/building-uis/using-react-hooks/">Using React Hooks</a> guide.</p></section>

```jsx
const App1 = () => {
  const color = useCell('pets', 'fido', 'color', store);
  return <>Color: {color}</>;
};

const app = document.createElement('div');
const root = ReactDOMClient.createRoot(app);
root.render(<App1 />);
console.log(app.innerHTML);
// -> 'Color: brown'

store.setCell('pets', 'fido', 'color', 'walnut');
console.log(app.innerHTML);
// -> 'Color: walnut'
```

<section><h2 id="use-components-for-reactive-apps">Use components for reactive apps.</h2><p>The react module provides simple React components with bindings that make it easy to create a fully reactive user interface based on a <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a>.</p><p>In this example, the library&#x27;s <a href="https://tinybase.org/api/ui-react/functions/store-components/rowview/"><code>RowView</code></a> component just needs a reference to the <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a>, the <code>tableId</code>, and the <code>rowId</code> in order to render the contents of that row. An optional <code>cellComponent</code> prop lets you override how you want each <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a> rendered. Again, all the listeners and updates are taken care of for you.</p><p>The module also includes a context Provider that sets up default for an entire app to use, reducing the need to drill all your props down into your app&#x27;s hierarchy.</p><p>Most of the demos showcase the use of these React hooks and components. Take a look at <a href="https://tinybase.org/demos/todo-app/todo-app-v1-the-basics/">Todo App v1 (the basics)</a> to see these user interface binding patterns in action.</p><p>Read more about the <a href="https://tinybase.org/api/ui-react/"><code>ui-react</code></a> module in the <a href="https://tinybase.org/guides/building-uis/">Building UIs</a> guides.</p></section>

  <RowView
    store={store}
    tableId="pets"
    rowId="fido"

<section><h2 id="apply-schemas-to-tables-and-values">Apply schemas to tables and values.</h2><p>By default, a <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a> can contain any arbitrary <a href="https://tinybase.org/api/store/type-aliases/store/value/"><code>Value</code></a>, and a <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a> can contain any arbitrary <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a>. But you can add a <a href="https://tinybase.org/api/store/type-aliases/schema/valuesschema/"><code>ValuesSchema</code></a> or a <a href="https://tinybase.org/api/store/type-aliases/schema/tablesschema/"><code>TablesSchema</code></a> to a <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a> to ensure that the values are always what you expect: constraining their types, and providing defaults.</p><p>In this example, we set a second <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a> without the <code>sold</code> <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a> in it. The schema ensures it&#x27;s present with default of <code>false</code>.</p><p>Read more about schemas in the <a href="https://tinybase.org/guides/schemas-and-persistence/using-schemas/">Using Schemas</a> guide.</p></section>

```js
store.setTablesSchema({
  pets: {
    species: {type: 'string'},
    color: {type: 'string'},
    sold: {type: 'boolean', default: false},
  },
});

store.setRow('pets', 'felix', {species: 'cat'});
console.log(store.getRow('pets', 'felix'));
// -> {species: 'cat', sold: false}

store.delTablesSchema();
```

<section><h2 id="persist-data-to-browser-file-or-server">Persist data to browser, file, or server.</h2><p>You can easily persist a <a href="https://tinybase.org/api/store/interfaces/store/store/"><code>Store</code></a> between browser page reloads or sessions. You can also synchronize it with a web endpoint, or (if you&#x27;re using TinyBase in an appropriate environment), load and save it to a file.</p><p>Read more about persisters in the <a href="https://tinybase.org/guides/schemas-and-persistence/persisting-data/">Persisting Data</a> guide.</p></section>

```js
const persister = createSessionPersister(store, 'demo');
await persister.save();

console.log(sessionStorage.getItem('demo'));
// -> '[{"pets":{"fido":{"species":"dog","color":"walnut","sold":true},"felix":{"species":"cat","sold":false}}},{"employees":3,"open":true}]'

persister.destroy();
sessionStorage.clear();

<section><h2 id="build-complex-queries-with-tinyql">Build complex queries with <a href="https://tinybase.org/guides/making-queries/tinyql/">TinyQL</a>.</h2><p>The <a href="https://tinybase.org/api/queries/interfaces/queries/queries/"><code>Queries</code></a> object lets you query data across tables, with filtering and aggregation - using a SQL-adjacent syntax called <a href="https://tinybase.org/guides/making-queries/tinyql/">TinyQL</a>.</p><p>Accessors and listeners let you sort and paginate the results efficiently, making building rich tabular interfaces easier than ever.</p><p>In this example, we have two tables: of pets and their owners. They are joined together by the pet&#x27;s ownerId <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a>. We select the pet&#x27;s species, and the owner&#x27;s state, and then aggregate the prices for the combinations.</p><p>We access the results by descending price, essentially answering the question: &quot;which is the highest-priced species, and in which state?&quot;</p><p>Needless to say, the results are reactive too! You can add listeners to queries just as easily as you do to raw tables.</p><p>Read more about <a href="https://tinybase.org/api/queries/interfaces/queries/queries/"><code>Queries</code></a> in the <a href="https://tinybase.org/guides/releases/#v2-0">v2.0 Release Notes</a>, the <a href="https://tinybase.org/guides/making-queries/">Making Queries</a> guide, and the <a href="https://tinybase.org/demos/car-analysis/">Car Analysis</a> demo and <a href="https://tinybase.org/demos/movie-database/">Movie Database</a> demo.</p></section>

This is useful for counting rows, but also supports averages, ranges of values, or arbitrary aggregations.</p><p>In this example, we create a new table of the pet species, and keep a track of which is most expensive. When we add horses to our pet store, the listener detects that the highest price has changed.</p><p>Read more about <a href="https://tinybase.org/api/metrics/interfaces/metrics/metrics/"><code>Metrics</code></a> in the <a href="https://tinybase.org/guides/metrics-and-indexes/using-metrics/">Using Metrics</a> guide.</p></section>

<section><h2 id="create-indexes-for-fast-lookups">Create indexes for fast lookups.</h2><p>An <a href="https://tinybase.org/api/indexes/interfaces/indexes/indexes/"><code>Indexes</code></a> object makes it easy to look up all the <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a> objects that have a certain value in a <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a>.</p><p>In this example, we create an index on the <code>species</code> <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a> values. We can then get the the list of distinct <a href="https://tinybase.org/api/store/type-aliases/store/cell/"><code>Cell</code></a> value present for that index (known as &#x27;slices&#x27;), and the set of <a href="https://tinybase.org/api/store/type-aliases/store/row/"><code>Row</code></a> objects that match each value.</p><p><a href="https://tinybase.org/api/indexes/interfaces/indexes/indexes/"><code>Indexes</code></a> objects are reactive too.
