`useTableCellIds`

The useTableCellIds hook returns the Ids of every Cell used across the whole Table, and registers a listener so that any changes to that result will cause a re-render.

useTableCellIds(
  tableId: string,
  storeOrStoreId?: StoreOrStoreId,
): Ids

Type Description

	Type	Description
`tableId`	`string`	The `Id` of the `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 `Cell` used across the whole `Table`.

tableId

string

The Id of the 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 Cell used across the whole Table.

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 useTableCellIds hook lets you indicate which Store to get data for: omit the optional final 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 Cell 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 useTableCellIds 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 {useTableCellIds} from 'tinybase/ui-react';

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

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

store.setCell('pets', 'felix', 'species', 'cat');
console.log(app.innerHTML);
// -> '<span>["color","species"]</span>'

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

import {Provider, useTableCellIds} 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(useTableCellIds('pets'))}</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>["color"]</span>'

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

import {Provider, useTableCellIds} 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(useTableCellIds('pets', '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>["color"]</span>'
