Complete Vue node lifecycle management system that safely extracts data from LiteGraph and renders nodes with working widgets in Vue components.
Key features:
- Safe data extraction pattern to avoid Vue proxy issues with LiteGraph private fields
- Event-driven lifecycle management using onNodeAdded/onNodeRemoved hooks
- Widget system integration with functional dropdowns, inputs, and controls
- Performance optimizations including viewport culling and RAF batching
- Transform container pattern for O(1) scaling regardless of node count
- QuadTree spatial indexing for efficient visibility queries
- Debug tools and performance monitoring
- Feature flag system for safe rollout
Architecture:
- LiteGraph remains source of truth for all graph logic and data
- Vue components render nodes positioned over canvas using CSS transforms
- Widget updates flow through LiteGraph callbacks to maintain consistency
- Reactive state separated from node references to prevent proxy overhead
Components:
- useGraphNodeManager: Core lifecycle management with safe data extraction
- TransformPane: Performance-optimized viewport container
- LGraphNode.vue: Vue node component with widget rendering
- Widget system: PrimeVue-based components for all widget types
- Add useFeatureFlags composable for Vue nodes
- Update coreSettings with Vue nodes feature flag
- Minor typing improvements in useTransformState
