Summary


In this episode, Simon Holthausen from the Svelte team joins to discuss remote functions and async Svelte, two


experimental features that are changing how developers interact with data in SvelteKit applications. Remote


functions offer a new RPC-like approach that provides better type safety, more granular data loading, and


improved developer experience compared to traditional load functions and form actions. The conversation


covers the technical implementation, design decisions, and future possibilities including caching, streaming, and


integration with Svelte's upcoming resource API. Simon also explains how async Svelte enables top-level await


in components with coordinated loading boundaries, making asynchronous work much easier to manage in both


SSR and SPA contexts.
