Minor Changes

• #14430 78011ba Thanks @ascorbic! - Adds support for async server rendering

  Svelte 5.36 added experimental support for async rendering. This allows you to use await in your components in several new places. This worked out of the box with client-rendered components, but server-rendered components needed some extra help. This update adds support for async server rendering in Svelte components used in Astro.

  To use async rendering, you must enable it in your Svelte config:

  // svelte.config.js export default { compilerOptions: { experimental: { async: true, }, }, };

  Then you can use await in your components:

  <script> let data = await fetch('/api/data').then(res => res.json()); </script> <h1>{data.title}</h1>

  See the Svelte docs for more information on using await in Svelte components, including inside $derived blocks and directly in markup.
