UNIVERSAL COMPOSITOR STATUS
Comprehensive guidelines for AI-assisted development within the Editor platform
Universal Visual Compositor - Current Status 🎨
🎯 Vision
A JSON-based imagination-to-life prototype builder where AI and developers can create ANYTHING through highly specific JSON definitions - a robust, powerful, modern design system with full persistence, functionality attachment, and infinite extensibility.
✅ Core Foundation - COMPLETE & PRODUCTION-READY
1. Vector Shape System ✅
- 8 Shape Types: circle, ellipse, rectangle, polygon, path, line, polyline, bezier
- Full SVG Support: All SVG attributes (fill, stroke, opacity, transforms)
- Shape Primitives: 18+ factory methods for quick creation
- Type-Safe: Comprehensive TypeScript definitions
- Precise: Infinite scalability through vector rendering
2. Interactive Canvas ✅
- Drag & Drop: Smooth, precise element dragging
- 8-Point Resize: Corner and edge handles with constraints
- Free Rotation: With shift-key snapping to 15° increments
- Selection System: Single and multi-select with keyboard shortcuts
- Zoom/Pan: Canvas navigation (ready to expand)
- Viewport Constraints: Elements stay within bounds
3. Connection System ✅
- Dual-Purpose Control Points: Reshape geometry OR connection ports
- 4 Path Types: straight, bezier, curved, orthogonal
- Arrow Styles: arrow, circle, square, diamond, or none
- Smart Connections: Follow elements when moved
- Connection Selection: Click to select, delete, style
- Cascade Delete: Remove element → auto-delete connections
4. Event-Driven Architecture ✅
- Proper Event Flow: Child → Parent component hierarchy
- Operation Events: dragEnd, resizeEnd, rotateEnd
- No setTimeout: Clean, reactive patterns
- State Management: Signal-based, precise control
- Mutual Exclusion: Operations don't interfere
5. Persistence ✅
- Auto-Save: All changes persist automatically
- Storage Integration: Uses
@storage-systemautoFlashState - Undo/Redo: Full history with 50-state buffer
- Multi-Element: Positions, sizes, rotations, connections
- Session Recovery: Survives page refresh
6. AI Generation (Basic) ✅
- Prompt Parsing: Natural language → composition
- Templates: Panda, robot, house, smiley, diagrams, flowcharts, wireframes
- Intent Detection: Drawings, diagrams, flowcharts, wireframes
- Element Generation: Creates positioned, styled elements
🏗️ Architecture Quality
Code Standards ✅
- Angular 20: Standalone components, signals, OnPush
- TypeScript Strict: No
anytypes, full type coverage - SOLID Principles: Single responsibility, dependency injection
- DRY: No code duplication
- Accessibility: ARIA labels, keyboard navigation
- Performance: Efficient change detection, computed signals

❌ Simple Methods - addCircle(), addText(), connect()
❌ Layouts - Grid, flow, stack auto-layout
❌ Groups - Compound shapes and nesting
Phase 4: Functionality System (Planned)
❌ Interaction Definitions - Attach click/hover/etc handlers via JSON ❌ Action System - Navigate, emit, animate, transform actions ❌ State Management - Element-level state for dynamic behaviors ❌ Event System - Custom events between elements ❌ Script Support - Sandboxed JavaScript execution
Phase 5: Enhanced AI Generator (Planned)
❌ JSON-Driven Templates - Load templates from JSON files ❌ Advanced Parsing - Better natural language understanding ❌ Modification - "Change the button to red", "Make it bigger" ❌ Smart Suggestions - Auto-improvements and optimizations
Phase 6: Export/Import System (Planned)
❌ Complete JSON Export - Full composition with all metadata ❌ SVG Export - Render to downloadable SVG ❌ PNG/JPEG Export - Raster image generation ❌ Copy/Paste - System clipboard integration ❌ Templates Library - Save and share compositions
Phase 7: Advanced Features (Future)
❌ Scroll Integration - Connect to existing @scroll-trigger library
❌ Path Morphing - Smooth shape transitions
❌ Animation Timeline - Keyframe-based animations
❌ Text Elements - Rich text editing
❌ Image Elements - Image upload and manipulation
❌ Layers - Layer management and organization
❌ Styles - Global style system (like CSS classes)
❌ Components - Reusable component instances
❌ Constraints - Auto-layout constraints
❌ Responsive - Breakpoint-based adaptations
Phase 8: Collaboration (Future)

✨ The Vision is Clear
We're building the Figma/Framer of JSON-based prototyping:
- Design through code (or AI)
- Everything is JSON
- Full interactivity
- Production-ready output
- Infinite extensibility
Current Status: Strong foundation (40%), needs JSON architecture and functionality system to reach full vision (60% remaining).
Estimated Time to V1.0: 2-4 weeks of focused development
