# frontend/ Frontend ownership and structure. - Source-managed React frontend lives in [frontend/react](C:/Users/siddh/OPENENV_RL/frontend/react). - Built with Vite and served by FastAPI at `/ui`. - UI is now module-based: - `Overview` - `Simulation Lab` - `Training Studio` - `Model Comparison` - Backend APIs remain under `/api/*`. Local frontend dev: 1. Start backend: - `.\.venv313\Scripts\python.exe scripts\run_local.py --host 0.0.0.0 --port 7860` 2. Start Vite dev server: - `cd frontend/react` - `npm install` - `npm run dev` 3. Open: - `http://localhost:5173` Build for backend serving: - `cd frontend/react` - `npm run build` Deployment path: - UI route: `/ui` - Asset route: `/ui/assets/*`
