`useTableIds`

The useTableIds hook returns the Ids of every Table in a Store, and registers a listener so that any changes to that result will cause a re-render.

useTableIds(storeOrStoreId?: StoreOrStoreId): Ids

Type Description

	Type	Description
`storeOrStoreId?`	`StoreOrStoreId`	The `Store` to be accessed: omit for the default context `Store`, provide an `Id` for a named context `Store`, or provide an explicit reference.
returns	`Ids`	An array of the `Ids` of every `Table` in the `Store`.

storeOrStoreId?

StoreOrStoreId

The Store to be accessed: omit for the default context Store, provide an Id for a named context Store, or provide an explicit reference.

returns

Ids

An array of the Ids of every Table in the Store.

A Provider component is used to wrap part of an application in a context, and it can contain a default Store or a set of Store objects named by Id. The useTableIds hook lets you indicate which Store to get data for: omit the optional parameter for the default context Store, provide an Id for a named context Store, or provide a Store explicitly by reference.

When first rendered, this hook will create a listener so that changes to the Table Ids will cause a re-render. When the component containing this hook is unmounted, the listener will be automatically removed.

Examples

This example creates a Store outside the application, which is used in the useTableIds hook by reference. A change to the data in the Store re-renders the component.

import React from 'react';
import {createRoot} from 'react-dom/client';
import {createStore} from 'tinybase';
import {useTableIds} from 'tinybase/ui-react';

const store = createStore().setCell('pets', 'fido', 'color', 'brown');
const App = () => <span>{JSON.stringify(useTableIds(store))}</span>;

const app = document.createElement('div');
createRoot(app).render(<App />);
console.log(app.innerHTML);
// -> '<span>["pets"]</span>'

store.setCell('species', 'dog', 'price', 5);
console.log(app.innerHTML);
// -> '<span>["pets","species"]</span>'

This example creates a Provider context into which a default Store is provided. A component within it then uses the useTableIds hook.

import {Provider, useTableIds} from 'tinybase/ui-react';
import React from 'react';
import {createRoot} from 'react-dom/client';
import {createStore} from 'tinybase';

const App = ({store}) => (
  <Provider store={store}>
    <Pane />
  </Provider>
);
const Pane = () => <span>{JSON.stringify(useTableIds())}</span>;

const store = createStore().setCell('pets', 'fido', 'color', 'brown');
const app = document.createElement('div');
createRoot(app).render(<App store={store} />);
console.log(app.innerHTML);
// -> '<span>["pets"]</span>'

This example creates a Provider context into which a Store is provided, named by Id. A component within it then uses the useTableIds hook.

import {Provider, useTableIds} from 'tinybase/ui-react';
import React from 'react';
import {createRoot} from 'react-dom/client';
import {createStore} from 'tinybase';

const App = ({store}) => (
  <Provider storesById={{petStore: store}}>
    <Pane />
  </Provider>
);
const Pane = () => <span>{JSON.stringify(useTableIds('petStore'))}</span>;

const store = createStore().setCell('pets', 'fido', 'color', 'brown');
const app = document.createElement('div');
createRoot(app).render(<App store={store} />);
console.log(app.innerHTML);
// -> '<span>["pets"]</span>'
