description	Starts the Vite dev server or full Tauri desktop app. Use when starting development or verifying UI changes in the running app.

run

When to use

• Before any visual verification step in Frontend Engineer or UX Designer roles
• To confirm a Tauri command is reachable from JS after wiring it up
• To reproduce a UI bug before and after a fix

Procedure

1. For Vite-only (React UI, no Rust backend): pnpm dev - serves on http://localhost:4200.
2. For full Tauri desktop app (includes Rust backend, IPC, file system): pnpm tauri:dev - opens the native desktop window with hot reload.
3. After running, check the terminal for Rust compile errors before inspecting the UI.
4. In Tauri dev mode, right-click the window and select Inspect to open browser devtools.

Failure modes

• Rust compile error on start → fix the Rust error shown in the terminal before proceeding to UI verification.
• Port 4200 in use → kill the existing process (lsof -ti:4200 | xargs kill) or change the port in apps/klank/vite.config.ts.
• Tauri window doesn't open → check apps/klank/src-tauri/tauri.conf.json §build.devUrl matches the Vite server address.
• pnpm tauri:dev not found → run pnpm install first to ensure the Tauri CLI is installed.
