🏗️ Architecture Highlights
Module-First Design
Every variant is now a BrowserModuleContract:
const variant = new VariantModuleWrapper(widgetVariant);
await variant.initialize().toPromise();
await variant.start().toPromise();
// Expose actions via manifest
variant.manifest.publicActions.apply
variant.manifest.publicActions.preview
variant.manifest.publicActions.duplicate
variant.manifest.publicActions.promoteToModule
Three-Tier Scoping
Global Variants (GoGrab Team)
├─ Read-only, production-ready
├─ Available across all universes
└─ 31 pre-built variants
Universe Variants (Space Builders)
├─ Shared across spaces in a universe
├─ Customizable per universe
└─ Can be public or private
Space Variants (Space Builders)
├─ Scoped to individual spaces
├─ Maximum flexibility
└─ Local experimentation
AI-Discoverable
Variants expose rich metadata through manifests:
- Tags: For semantic search
- Public Actions: For programmatic access
- Category: For organization
- Description: For AI context
- Usage Stats: For popularity ranking
🔧 Technical Implementation
Fixed Architectural Issues
ActionRegistry Integration
- Problem: ActionRegistry required action classes, not function registrations
- Solution: Simplified VariantActionProvider to provide direct service methods
EventBus API
- Problem: Used
emit()instead ofpublish() - Solution: Updated to use
EventBusService.publish()with proper event structure
- Problem: Used
Module Contract Compliance
- Problem: Lifecycle methods returned Promises instead of Observables
- Solution: Converted all methods to return RxJS Observables
Type System Alignment
- Problem: Used invalid category types (
'widget-variant','widget') - Solution: Mapped to valid types (
'utility','crud','workflow')
- Problem: Used invalid category types (
Circular Dependencies
- Problem:
WidgetVarianttype caused circular dep between libraries - Solution: Moved types to foundational
widgetslibrary
- Problem:
Ambiguous Exports
- Problem: Two
WidgetVariantinterfaces - Solution: Renamed legacy interface to
WidgetModuleVariant
- Problem: Two
