local-dev-serve-troubleshooting

Common local dev setups

UI fast loop (Vite dev server)

• Start UI:

  • npm run dev

• In another terminal, start the Rust server:

  • cargo run -- serve --port 8080

Notes:

• lotar serve port must be set with --port (the short -p is reserved for the global --project flag).
  • Correct: lotar serve --port 9000
  • Also accepted: lotar serve 9000 (positional port; kept for backward compatibility)
  • Incorrect (sets project, not port): lotar serve -p 9000
  • See: docs/help/serve.md

Production-like UI (embedded/static bundle)
