trpc-sveltekit

• Purpose: tRPC-SvelteKit enables end-to-end typesafe APIs for SvelteKit applications, allowing developers to "move fast and break nothing" by leveraging tRPC's type-safe communication between client and server.

• Target Audience: SvelteKit developers who want to integrate tRPC for type-safe API interactions, with additional experimental WebSocket support for real-time functionality.

• Key Features:

  • SvelteKit Integration: Designed specifically for SvelteKit, compatible with adapters like @sveltejs/adapter-node, -vercel, and -netlify.
  • tRPC Compatibility: Supports tRPC v10 (with legacy support for v9 in older versions).
  • WebSocket Support (Experimental): Enables real-time communication via WebSockets when using @sveltejs/adapter-node, though with some limitations (e.g., hardcoded URL /trpc, no prerendering support).

• Core Workflow:

  • Define a tRPC router and context.
  • Set up SvelteKit hooks to handle tRPC requests.
  • Create a client helper for easy tRPC calls in pages.
  • Call procedures directly from Svelte components with full type safety.

• Examples: Includes practical implementations like simple, bookstall, and websocket .

• Documentation: Detailed guides available at icflorescu.github.io/trpc-sveltekit .

• Experimental WebSocket Details:

  • Requires @sveltejs/adapter-node and ws.
  • Uses a Vite plugin and custom server setup to handle WebSocket upgrades.
  • All tRPC calls are routed through WebSockets in this mode (may change
