sveltekit-remote-functions

Remote functions in SvelteKit let you call server logic directly from the client using typed, JSON-serializable calls. Define functions in *.remote.ts files and invoke them from client components; the framework handles serialization, validation via StandardSchemaV1, and error propagation automatically.

command() executes one-time server actions like writes or deletes; query() handles repeated reads with batching support; form() provides progressive enhancement for form submissions. Each pattern suits different interaction types and server-side requirements.

Yes. Remote functions support getRequestEvent() to access the underlying SvelteKit request context, enabling you to read headers, cookies, sessions, and other request data within your server-side function logic.

Remote functions enforce StandardSchemaV1 validation for JSON-serializable inputs and outputs. Define schemas to validate data before execution and ensure type safety across the client-server boundary.

Remote functions use deterministic serialization to convert client inputs and server outputs to JSON. This ensures consistent, predictable data transformation and reliable error propagation across network calls.

Yes. The query() pattern supports batching, allowing multiple read requests to be grouped and executed efficiently on the server, reducing round trips and improving performance in client-heavy applications.
