YAML Format Support - Implementation Summary
✅ Successfully Implemented
New UI Features in Swagger Interface
The Swagger UI now includes four format selection buttons positioned in the top-right corner:
- 📄 JSON - Direct download of JSON specification (
/swagger.json) - 📝 YAML - Direct download of YAML specification (
/swagger.yaml) - 📋 JSON URL - Copy JSON endpoint URL to clipboard
- 📋 YAML URL - Copy YAML endpoint URL to clipboard
New Endpoint
GET /swagger.yaml- Serves OpenAPI 3.0.3 specification in YAML format- Same authentication requirements as JSON endpoint
- Full caching support with format-specific cache keys
- Rate limiting protection
- Content-Type:
application/x-yaml
Enhanced Features
- Dual Format Caching: Separate cache entries for JSON and YAML
- Copy to Clipboard: JavaScript functionality with visual feedback
- Format Consistency: Both formats contain identical API information
- Professional Styling: Clean button design that matches the Swagger UI theme
🎯 User Benefits
- Easy Access: One-click access to both JSON and YAML formats
- Developer Friendly: YAML format is more readable for manual inspection
- Tool Integration: YAML format works better with many OpenAPI tools
- Quick Sharing: Copy URL buttons make it easy to share specific format URLs
🔧 Technical Details
- YAML Generation: Uses PyYAML 6.0.2 with optimized settings
- Caching Strategy: Format-specific cache keys (
*_json,*_yaml) - Performance: No impact on existing JSON functionality
- Error Handling: Proper error responses for both formats
