You can use the built-in tick function in Svelte to wait for any pending state changes in a component, before executing code:

Copied to clipboard!
<script>
    import { beforeUpdate, tick } from 'svelte';

    beforeUpdate(async () => {
        console.log('The component is about to update');

        await tick();
        console.log('The component has been updated');
    });
</script>
Tick.svelte

The function returns a Promise that resolves once pending state changes have been applied.
