Server Setup (Linux)

The server requires X11 to simulate mouse and keyboard events.

1. Configuration

Navigate to the server directory and create a .env file:

cd server
cp .env.example .env # Or create one manually

Edit .env:

WS_PORT=1488
SERVER_PASSWORD=1234

2. Permissions (X11)

Since the server runs in Docker, you must allow it to access your display:

xhost +local:docker

3. Run with Docker (Recommended)

docker compose up -d --build

4. Run without Docker

If you have Go installed locally, install dependencies and run:

sudo apt install libx11-dev libxtst-dev libpng-dev # Debian/Ubuntu/PopOS
go mod download
go run cmd/main.go

Client Setup (Mobile)

The client is built with Expo (React Native).

1. Install Dependencies

cd client
npm install

2. Start Expo

npx expo start

Scan the QR code with the Expo Go app on your Android or iOS device.

3. Connecting

• Ensure your phone and PC are on the same Wi-Fi network.
• Use the Search icon in the app to scan the network, or tap the + button to add your PC's IP manually.
• Default Port: 1488
• Default Password: 1234

Troubleshooting

• "Could not open main display": Ensure you ran xhost +local:docker.
• Connection Timed Out: Check your PC's firewall. You might need to allow the port:

  sudo ufw allow 1488/tcp

• Scrolling doesn't work: Ensure your Linux environment uses X11 (Wayland is currently not supported by robotgo).
