Manual Installation

1. Install Go 1.21 or later
2. Clone the repository
3. Install dependencies:

   go mod download
   

4. Build the application:

   go build -o stash-vr-companion
   

5. Run the application:

   ./stash-vr-companion
   

Configuration

All configuration is done via environment variables:

Required Configuration

• API_URL: Stash GraphQL endpoint (e.g., http://localhost:9999/graphql)

Optional Configuration

• API_KEY: Stash API key (required if Stash has authentication enabled)
• PORT: Server port (default: 8080)
• HOST: Server host (default: 0.0.0.0)
• CACHE_DIR: Cache directory (default: ./cache)
• HSP_DIR: HSP files directory (default: ./hsp)
• LOG_LEVEL: Logging level (default: info)
• VERIFY_SSL: Enable SSL certificate verification (default: true)
• DISABLE_CERT_VERIFICATION: Disable SSL certificate verification (default: false)
• TITLE_AS_FILENAME: Use filename as title (default: false)
• THUMBNAIL_WIDTH: Thumbnail width (default: 472)
• THUMBNAIL_HEIGHT: Thumbnail height (default: 290)

Authentication Configuration

• USERNAME: Username for authentication
• PASSWORD: Bcrypt hashed password for authentication

API Endpoints

VR Platform APIs

• GET /deovr - DeoVR library
• GET /deovr/:scene_id - DeoVR scene details
• GET /heresphere - HereSphere library
• POST /heresphere/auth - HereSphere authentication
• GET /heresphere/:scene_id - HereSphere scene details
• GET /gizmovr_scene/:scene_id - GizmoVR scene data

Utility APIs

• GET /stash-metadata - Stash metadata export
• GET /health - Health check
• GET /info - Server information
• GET /refresh-cache - Refresh cache
• GET /clear-cache - Clear cache

Proxy APIs

• GET /image/:scene_id - Scene image proxy
• GET /thumb/:scene_id - Scene thumbnail proxy
• GET /heatmap/:scene_id - Scene heatmap proxy
• GET /script/:scene_id - Scene script proxy

Performance Improvements

The Go version provides several performance improvements over the Python version:

• Memory Efficiency: Lower memory usage with efficient data structures
• Concurrent Processing: Goroutines for background tasks and concurrent request handling
• Faster Startup: Quicker application startup and cache initialization
• Better Resource Management: Efficient HTTP client pooling and connection reuse
• Type Safety: Compile-time type checking prevents runtime errors

Development

Prerequisites

• Go 1.21 or later
• Access to a Stash server for testing

Running in Development

# Set environment variables
export API_URL=http://localhost:9999/graphql
export API_KEY=your-api-key
export LOG_LEVEL=debug

# Run the application
go run main.go

Building

# Build for current platform
go build -o stash-vr-companion

# Cross-compile for different platforms
GOOS=linux GOARCH=amd64 go build -o stash-vr-companion-linux
GOOS=windows GOARCH=amd64 go build -o stash-vr-companion-windows.exe
GOOS=darwin GOARCH=amd64 go build -o stash-vr-companion-mac

Migration from Python Version

The Go version maintains API compatibility with the Python version while providing:

• Same REST endpoints and response formats
• Compatible authentication methods
• Identical VR platform integration
• Same configuration options (via environment variables)

Simply replace the Python version with the Go version using the same configuration.

Troubleshooting

Common Issues

1. Connection refused: Check that Stash is running and accessible
2. Authentication failed: Verify API key or username/password
3. SSL errors: Set DISABLE_CERT_VERIFICATION=true for self-signed certificates
4. Cache not updating: Check network connectivity to Stash server

Debug Mode

Enable debug logging for troubleshooting:

export LOG_LEVEL=debug

Health Check

Check if the service is running:

curl http://localhost:8080/health
