| # 🤖 LeRobot Arena Transport Server with UI | |
| A complete Docker deployment of the LeRobot Arena Transport Server with integrated web UI. This combines the FastAPI backend with a SvelteKit frontend in a single container, inspired by the [LeRobot Arena Hugging Face Space](https://huggingface.co/spaces/blanchon/LeRobot-Arena). | |
| ## 🚀 Quick Start with Docker | |
| The easiest way to run the complete LeRobot Arena Transport Server is using Docker, which sets up both the frontend and backend automatically. | |
| ### Prerequisites | |
| - [Docker](https://www.docker.com/get-started) installed on your system | |
| - [Docker Compose](https://docs.docker.com/compose/install/) (usually included with Docker Desktop) | |
| ### Step-by-Step Instructions | |
| 1. **Navigate to the transport server directory** | |
| ```bash | |
| cd services/transport-server | |
| ``` | |
| 2. **Build the Docker image** | |
| ```bash | |
| docker build -t lerobot-arena-transport . | |
| ``` | |
| 3. **Run the container** | |
| ```bash | |
| docker run -p 7860:7860 -e SERVE_FRONTEND=true lerobot-arena-transport | |
| ``` | |
| 4. **Access the application** | |
| - **Frontend**: http://localhost:7860 | |
| - **Backend API**: http://localhost:7860/api | |
| - **API Documentation**: http://localhost:7860/api/docs | |
| 5. **Stop the container** | |
| ```bash | |
| # Find the container ID | |
| docker ps | |
| # Stop the container | |
| docker stop <container_id> | |
| ``` | |
| ### Alternative Build & Run Options | |
| **One-liner build and run:** | |
| ```bash | |
| docker build -t lerobot-arena-transport . && docker run -p 7860:7860 -e SERVE_FRONTEND=true lerobot-arena-transport | |
| ``` | |
| **Run with custom environment variables:** | |
| ```bash | |
| docker run -p 8080:7860 \ | |
| -e SERVE_FRONTEND=true \ | |
| -e PORT=7860 \ | |
| -e HOST=0.0.0.0 \ | |
| lerobot-arena-transport | |
| ``` | |
| **Run with volume mounts for logs:** | |
| ```bash | |
| docker run -p 7860:7860 \ | |
| -e SERVE_FRONTEND=true \ | |
| -v $(pwd)/logs:/home/user/app/logs \ | |
| lerobot-arena-transport | |
| ``` | |
| ## 🛠️ Development Setup | |
| For local development with hot-reload capabilities: | |
| ### Backend Development | |
| ```bash | |
| # Navigate to server directory | |
| cd server | |
| # Install Python dependencies (using uv) | |
| uv sync | |
| # Start the backend server only | |
| python api.py | |
| ``` | |
| ### Frontend Development | |
| ```bash | |
| # Navigate to demo directory | |
| cd demo | |
| # Install dependencies | |
| bun install | |
| # Start the development server | |
| bun run dev | |
| ``` | |
| ### Client Library Development | |
| ```bash | |
| # Navigate to client library | |
| cd client/js | |
| # Install dependencies | |
| bun install | |
| # Build the client library | |
| bun run build | |
| ``` | |

| ## 🐳 Docker Information | |
| The Docker setup includes: | |
| - **Multi-stage build**: Optimized for production using Bun and uv | |
| - **Client library build**: Builds the TypeScript client first | |
| - **Frontend build**: Compiles SvelteKit app to static files | |
| - **Backend integration**: FastAPI serves both API and static files | |
| - **Port mapping**: Single port 7860 for both frontend and API | |
| - **User permissions**: Properly configured for Hugging Face Spaces | |
| - **Environment variables**: Configurable via environment | |
| ### Environment Variables | |
| - `SERVE_FRONTEND=true`: Enable frontend serving (default: false) | |
| - `PORT=7860`: Port to run the server on (default: 7860) | |
| - `HOST=0.0.0.0`: Host to bind to (default: 0.0.0.0) | |
| ## 🌐 What's Included | |
| ### Backend Features | |
| - **Real-time Robot Control**: WebSocket-based communication | |
| - **Video Streaming**: WebRTC video streaming capabilities | |
| - **REST API**: Complete robotics control API | |
| - **Room Management**: Create and manage robot control sessions | |
| - **Health Monitoring**: Built-in health checks and logging | |
| ### Frontend Features | |
| - **Dashboard**: Server status and room overview | |
| - **Robot Control**: 6-DOF robot arm control interface | |
| - **Real-time Monitoring**: Live joint state visualization | |
| - **Workspace Management**: Isolated environments for different sessions | |

| This script will build the image, start a container, test all endpoints, and clean up automatically. | |
| ## 🚨 Troubleshooting | |
| ### Port Conflicts | |
| If port 7860 is already in use: | |
| ```bash | |
| # Check what's using the port | |
| lsof -i :7860 | |
| # Use different port | |
| docker run -p 8080:7860 -e SERVE_FRONTEND=true lerobot-arena-transport | |
| ``` | |
| ### Container Issues | |
| ```bash | |
| # View logs | |
| docker logs <container_id> | |
| # Rebuild without cache | |
| docker build --no-cache -t lerobot-arena-transport . | |
| # Run with verbose logging | |
| docker run -p 7860:7860 -e SERVE_FRONTEND=true -e LOG_LEVEL=debug lerobot-arena-transport | |
| ``` | |
| ### Development Issues | |
| ```bash | |
| # Clear node modules and reinstall (for local development) | |
| cd demo | |
| rm -rf node_modules | |
| bun install | |
| # Clear SvelteKit cache | |
| rm -rf .svelte-kit | |
| bun run dev | |
| # Re-link client library (if needed for local development) | |
| cd ../client/js | |
| bun link | |
| cd ../../demo | |
| bun link lerobot-arena-client | |
| ``` | |
| ### Client Library Issues | |
| ```bash | |
| # Rebuild client library | |
| cd client/js | |
| bun run clean | |
| bun run build | |
| ``` | |
