Graph Component Refactoring Summary

· 2 min read

Execution Plan​

The goal was to refactor the Graph component system from a single 3200+ line file into a modular architecture with focused components, hooks, and utilities.

Planned Components​

  1. GraphMenuBar.tsx - Menu bar with control buttons
  2. GraphInfoPanel.tsx - Side panel for node/edge information
  3. GraphCanvas.tsx - ForceGraph2D wrapper component

Planned Hooks​

  1. useGraphState.ts - Centralized state management
  2. useGraphData.ts - Data transformation and flattening
  3. useGraphInteractions.ts - Event handler management

Planned Documentation​

  1. Storybook setup and stories for all components
  2. Architecture documentation
  3. Usage guides

Execution Results / Attempts​

✅ Completed Components​

  1. GraphMenuBar.tsx ✅

    • Menu bar with control buttons
    • ~100 lines

  2. GraphInfoPanel.tsx ✅

    • Side panel for node/edge information
    • ~400 lines
    • Handles node display, edge display, connections, external links
    • Fully documented with Storybook stories

  3. GraphCanvas.tsx ✅

    • ForceGraph2D wrapper component
    • ~150 lines
    • Handles canvas rendering configuration

✅ Completed Hooks​

  1. useGraphState.ts ✅

    • Centralized state management
    • ~120 lines
    • Returns { state, actions } object

  2. useGraphData.ts ✅

    • Data transformation and flattening

    • Handles hierarchical node flattening

  3. useGraphInteractions.ts ✅

    • Event handler management

✅ Utility Files (Previously Created)​

  1. GraphDataUtils.ts ✅
  2. GraphNodeUtils.ts ✅
  3. GraphRenderingUtils.ts ✅
  4. GraphTextUtils.ts ✅
  5. graphUtils.ts ✅ (re-export for backward compatibility)

    • Webpack configuration for canvas support

  2. .storybook/preview.ts ✅

    • Global Storybook settings
    • Decorators and parameters

  3. GraphMenuBar.stories.tsx ✅

    • Menu bar stories
    • Multiple examples (default, dark mode, etc.)

    • Info panel stories
    • Node/edge examples, dark mode, differentiating edges

  5. Graph.stories.tsx ✅

    • Architecture overview
    • Component composition examples

✅ Documentation​

  1. README.md ✅

    • Complete component system documentation
    • Usage examples
    • File structure

  2. COMPONENT_ARCHITECTURE.md ✅

    • Detailed architecture documentation
    • Component hierarchy diagrams
    • Data flow diagrams

    • Status tracking

📊 Impact Achieved​

File Size Reduction:

  • Before: Single file with ~3,219 lines
  • After: Split into 10+ focused files
  • Main File: Will be reduced to ~800-1000 lines after full refactor

Organization:

  • Components: 3 focused components
  • Hooks: 3 custom hooks
  • Utilities: 4 utility files (previously created)
  • Stories: 3 Storybook story files

Benefits Achieved: ✅ Better code organization ✅ Improved maintainability ✅ Enhanced testability ✅ Interactive documentation (Storybook) ✅ Reusable components ✅ Clear separation of concerns

⏳ Remaining Work​

  1. Refactor GraphRendererImpl ⏳

    • Update to use new components
    • Replace inline code with component imports
    • Maintain backward compatibility

  2. Testing ⏳

    • Add unit tests for components
    • Add integration tests
    • Test Storybook stories

  3. Performance ⏳

    • Profile component rendering
    • Optimize re-renders
    • Code splitting optimization
