- Refactor TimeParsingService to parse time strings to UTC only
- Remove minutesAgo from RadarFrame and FrameMetadata models
- Update CaptureFramesStep to extract UTC timestamps directly
- Update CacheService to store/load ObservationTime instead of MinutesAgo
- Update BomRadarService to use AbsoluteObservationTime directly
- Remove all backward compatibility code for old cache folders
- Update documentation and test SPA to calculate minutes ago on client
- Fix step registration to register concrete types for DI resolution
- Fix hosted service registration to use reflection correctly
- Remove OpenAPI/Swagger support and all related code
- Standardize configuration: remove hardcoded defaults, all defaults from appsettings.json
- Configuration values throw exceptions if missing (except Debug:Enabled defaults to false)
- Refactor CacheManagementService: extract ProcessLocationsAsync helper, remove duplicate code
- Combine UpdateStaggerSeconds and LocationStaggerSeconds into single LocationStaggerSeconds config
- Move config reads to constructors for better performance
- Update README and docker-compose.yml to reflect configuration changes
Major architectural changes:
- Replace monolithic ScrapingService with workflow-based system
- Extract scraping logic into discrete, testable steps
- Add configuration-driven selectors, JavaScript templates, and text patterns
- Implement step registry and workflow factory for extensibility
- Add PageState tracking and step dependencies
- Make IWorkflow generic to support different response types
New components:
- Scraping steps organized by category (Navigation, Search, Map, Metadata, Capture)
- BaseScrapingStep base class with common dependencies
- ScrapingContext for shared state between steps
- RadarScrapingWorkflow orchestrating step execution
- SelectorService for configurable element selection
- Configuration models (SelectorConfig, TextPatternsConfig, JavaScriptTemplatesConfig)
Performance and monitoring:
- Add step-level timing metrics with historical tracking
- Log step durations and compare to averages
- Warn on slow steps/workflows (50%+ slower than average)
- Integrate metrics with CacheService
Configuration improvements:
- Externalize all selectors to appsettings.json
- Externalize JavaScript templates to appsettings.json
- Externalize text patterns to appsettings.json
- Support Docker configuration via mounted appsettings.json
- Remove hardcoded waits, use configurable timeouts
Bug fixes:
- Fix DebugService collection modification exception
- Fix ResetToFirstFrameStep click interception with JavaScript fallback
- Remove minutes ago fallback, use timestamp parsing only
- Update timestamp parsing for new BOM website format
Documentation:
- Update README with new architecture details
- Add configuration section with Docker guidance
- Add development guidelines for extending scraping system
- Add performance monitoring documentation
- Fix TimeRangeError to properly extract properties from anonymous objects
- Add suggestions field to timeseries error response examples in README
- Enhance demo app to use suggested ranges from error responses
- Make time series endpoint consistent with main radar endpoint (triggers background update, provides cache status)
- Add validation for large time ranges with meaningful error messages
- Make time range limit configurable via TimeSeries:MaxTimeRangeHours (defaults to CacheRetentionHours)
- Remove arbitrary max limits from demo app settings (frame interval, refresh interval)
- Update documentation to reflect configurable limits and improved error handling
