There's no rivetkit/vite export. Let me check what's actually available and find the correct approach for the Vite plugin.No Vite plugin export. Let me check the skill documentation and examples to see the correct approach for file-system driver with Vite.I see - the example uses vite-plugin-srvx with Hono. Let me look for a simpler setup that uses file-system driver without needing a full server.Let me find an example that uses file-system driver specifically.I see - createFileSystemDriver is exported from rivetkit. The hello-world example uses Hono with srvx. Let me follow that pattern but look for a simpler vanilla JS approach. Let me check how registry.serve() works.Now I understand. The registry.serve() starts its own server. I need to follow the hello-world example pattern: use Hono with srvx for Vite integration. Let me update the project to match that approach.Now let me update the actors to use the file-system driver and reinstall dependencies.The server starts. Now let me test the metadata endpoint to verify everything is working.The metadata endpoint works. But I notice it says "clientEndpoint":"http://127.0.0.1:6420" - that's the standalone runner mode, not serverless. Let me check the actor driver configuration. Actually, looking closer, the issue is that createFileSystemDriver() creates a runner-mode driver, but we need serverless for Vite. Let me check how the hello-world example configures this.I see - the hello-world example doesn't specify a driver! It uses the default. Let me check what the default driver is.The default driver is already file-system when no endpoint/token is set. Looking at the metadata output again, the clientEndpoint being 127.0.0.1:6420 is the correct behavior for the file-system driver - it still needs a runner to handle WebSocket connections.

Let me test the actual counter functionality by making a quick test.The HTML is served. Let me also kill any lingering vite processes and check the main.ts to ensure the client connects properly.The setup looks correct. Let me simplify the actors.ts to not explicitly specify a driver since the default is already file-system when running locally.Now let me add a tsconfig.json for proper TypeScript support.The server is running. Now let me verify the final project structure.The project is complete. Here's a summary:

Project created at /tmp/skill-eval-js-counter-1770947656776

Files:

• actors.ts - Counter actor with increment and getCount actions
• server.ts - Hono server exposing the registry handler at /api/rivet/*
• vite.config.ts - Vite config with srvx plugin for server-side code
• index.html - Counter UI with + button
• main.ts - Vanilla JS client connecting to the counter actor
• package.json - Dependencies including rivetkit, hono, srvx, and vite
• tsconfig.json - TypeScript configuration

To run:

cd /tmp/skill-eval-js-counter-1770947656776
npm run dev

The app runs on port 5173 and uses the file-system driver (default when no endpoint/token is set) for standalone mode without an external server.

Friction logged:

• The skill documentation mentioned rivetkit/vite plugin but it doesn't exist in the package exports. The correct approach is to use vite-plugin-srvx with a Hono server, following the hello-world example pattern.
