SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Solves the problem of creating reliable, type-safe remote procedures between SvelteKit client components and server handlers, reducing boilerplate and preventing unsafe data exchange.

Core Features & Use Cases

Supports command() for one-time server actions (writes/updates)
Supports query() for repeated reads and batched requests
Supports form() for progressive enhancement forms
Validates inputs with StandardSchemaV1 and handles JSON-serializable data
Provides guidance and examples to jumpstart development with .remote.ts files

Quick Start

Create a new file ending in .remote.ts and export a function using command() or query(), then call it from the client.

FAQPage Schema

How do I create type-safe remote function calls in SvelteKit server actions?▼

Type-safe remote function calls in SvelteKit are created by exporting functions using command(), query(), or form() within .remote.ts files, which you then invoke directly from client components to ensure end-to-end type safety.

When should I use command() versus query() for SvelteKit server actions?▼

Use command() for one-time server actions like writes or updates in SvelteKit. Use query() for repeated reads or batched data fetches, and use form() for progressive enhancement forms that maintain type safety.

Can I use StandardSchemaV1 validation for SvelteKit server action inputs?▼

This approach enforces JSON-serializable inputs and outputs and uses StandardSchemaV1 for input validation, preventing unsafe data exchange between SvelteKit client components and server handlers.

How do I access cookies and headers inside SvelteKit remote functions?▼

Yes, you can access request event data like cookies and headers by calling the exposed getRequestEvent function within your remote server-side handlers.

Does SvelteKit type-safe RPC support non-JSON-serializable data?▼

No, this approach is strictly limited to JSON-serializable inputs and outputs to ensure reliable data exchange between SvelteKit client components and server-side handlers.
