Remote Control
summary
SvelteKit adds remote modules that declare server-held state and expose queries and commands, wired via Vite/Rollup plugin hooks (resolveId/load/transform/renderChunk/writeBundle). The team builds per-function endpoints by loading modules on the server during transform, returns single-flight mutation responses that include updated queries, and supports optimistic updates with automatic rollback. Demos show a persisted counter, batched weather requests, and form handlers with Valibot/Zod validation and client-side enhancements; the system works today but relies on heavy plugin-API hacks.
