What Works Right Now

✅ You Can Use These Features in Production

  1. Define Reports with DSL

    • Full Spark DSL integration
    • Band hierarchy (report_header, page_header, detail, group_footer, etc.)
    • Element types (field, label, box, line, image, chart)
    • Parameters with validation
    • Variables with calculations
  2. Generate Charts

    • Bar, line, pie, area, scatter charts using Contex
    • SVG output for embedding in reports
    • Data aggregation and grouping
    • Customizable styling
  3. Stream Large Datasets

    • Ash.stream! with keyset pagination
    • Memory-efficient processing
    • Automatic batch size management
    • Aggregation during streaming
  4. Load Data from Ash Resources

    • Query building with parameters
    • Relationship loading
    • Filtering and sorting
    • Group processing
  5. Format Data (i18n)

    • CLDR-based formatting
    • Numbers, dates, currencies
    • Multiple locale support
    • RTL text direction

⚠️ Use With Caution (Untested)

These features are implemented but lack comprehensive test coverage:

  1. HTML Report Generation
  2. HEEX/LiveView Reports
  3. PDF Generation
  4. JSON Export
  5. Interactive Features (filters, pivots, statistics)

Recommendation: Test thoroughly in your own environment before using these features in production.

❌ Don't Try to Use These Yet

These features are documented but not implemented:

  1. Streaming configuration DSL (e.g., streaming section)
  2. Security DSL (e.g., security section)
  3. Monitoring DSL (e.g., monitoring section)
  4. Cache configuration DSL (e.g., cache section)
  5. ChartJS/D3/Plotly chart providers (status unclear)
