`getResultRow`

The getResultRow function returns a reactive object reflecting a result Row in a result Table, and registers a listener so that any changes will update current.

getResultRow(
  queryId: MaybeGetter<string>,
  rowId: MaybeGetter<string>,
  queriesOrQueriesId?: MaybeGetter<undefined | QueriesOrQueriesId>,
): {current: Row}

	Type	Description
`queryId`	`MaybeGetter<string>`	The `Id` of the Query (or a getter returning it).
`rowId`	`MaybeGetter<string>`	The `Id` of the `Row` (or a getter returning it).
`queriesOrQueriesId?`	`MaybeGetter<undefined \| QueriesOrQueriesId>`	The `Queries` object to use (plain or getter), or its `Id`.
returns	`{current: Row}`	A reactive object with a `current` `Row` property.

Example

This example passes a TinyBase object into a Svelte component and reads the reactive object's current property.

App.svelte

<svelte:options runes={true} />

<script>
  import {getResultRow} from 'tinybase/ui-svelte';

  let {queries} = $props();

  const result = getResultRow('petColors', 'fido', queries);
</script>

{JSON.stringify(result.current)}

import {flushSync, mount} from 'svelte';
import {createQueries, createStore} from 'tinybase';
import App from './App.svelte';

const store = createStore()
  .setTables({
    pets: {
      fido: {species: 'dog', color: 'brown', sold: false, next: 'felix'},
      felix: {species: 'cat', color: 'black', sold: true},
    },
    species: {dog: {price: 5}, cat: {price: 4}},
  })
  .setValues({open: true, employees: 3});
const queries = createQueries(store).setQueryDefinition(
  'petColors',
  'pets',
  ({select}) => select('color'),
);
const app = document.body.appendChild(document.createElement('div'));
flushSync(() => mount(App, {target: app, props: {queries}}));
console.log(app.textContent);
// -> '{"color":"brown"}'
