Async réactif svelte

let package_name = 'svelte';
let download_count = 0;
$: fetch('https://api.npmjs.org/downloads/point/last-week/' + package_name)
	.then(response => response.json())
	.then(data => download_count = data.downloads || 0);

// Updating `package_name` will asynchronously update `download_count`
