Mindmap Components Migration - Phase 3

Status: ✅ Complete (with notes)
Commit: aa267b5 - "feat: add mindmap components from jarvis frontend"
Branch: feature/jarvis-fe-migration

Completed Tasks

1. ✅ Directory Structure Created

apps/web/src/components/mindmap/
├── controls/
│   ├── ExportButton.tsx
│   └── NodeCreateModal.tsx
├── hooks/
│   └── useGraphData.ts
├── nodes/
│   ├── BaseNode.tsx
│   ├── ConceptNode.tsx
│   ├── IdeaNode.tsx
│   ├── ProjectNode.tsx
│   └── TaskNode.tsx
├── index.ts
├── MermaidViewer.tsx
├── MindmapViewer.tsx
└── ReactFlowEditor.tsx

2. ✅ Components Copied

All mindmap components have been successfully migrated:

• Main viewers: ReactFlowEditor, MindmapViewer, MermaidViewer
• Node types: BaseNode, ConceptNode, TaskNode, IdeaNode, ProjectNode
• Controls: NodeCreateModal, ExportButton
• Hooks: useGraphData (with KnowledgeNode, KnowledgeEdge types)

3. ✅ Barrel Export Created

components/mindmap/index.ts exports all components and types for clean imports

4. ✅ Route Created

• Created /mindmap page at apps/web/src/app/mindmap/page.tsx
• Includes proper metadata and layout

5. ✅ Dependencies Added

• Copied lib/auth-client.ts (BetterAuth integration)
• Created lib/api.ts (session management utilities)

Import Updates

No @jarvis/* imports were present in the mindmap components - they were already using relative paths and @/lib/* aliases, which are compatible with the Mosaic structure.

Type Adaptations

The mindmap uses its own KnowledgeNode and KnowledgeEdge types, which are specific to the knowledge graph feature and not part of the general Mosaic entity types (Task, Project, etc. from @mosaic/shared). This is correct as the mindmap represents a different data model.

Known Issues & Next Steps

Missing Package Dependencies

The build currently fails due to missing packages required by auth-client.ts:

better-auth
better-auth/react
better-auth-credentials-plugin
better-auth-credentials-plugin/client

Resolution: These packages need to be added to the workspace:

pnpm add better-auth better-auth-credentials-plugin

ReactFlow Dependencies

Verify that @xyflow/react is installed:

pnpm add @xyflow/react

Mermaid Dependency

Verify that mermaid is installed:

pnpm add mermaid

Testing Checklist

Once dependencies are installed:

• Build completes without errors
• Navigate to /mindmap route
• Create a knowledge node
• Verify ReactFlow interactive editor renders
• Test Mermaid diagram view
• Test export functionality
• Verify node type rendering (Concept, Task, Idea, Project)

API Integration

The mindmap components expect a backend knowledge graph API at:

• Base URL: process.env.NEXT_PUBLIC_API_URL (default: http://localhost:8000)
• Endpoints:
  • GET /api/v1/knowledge/graph - Fetch graph data
  • GET /api/v1/knowledge/mermaid - Fetch Mermaid diagram
  • POST /api/v1/knowledge/nodes - Create node
  • PUT /api/v1/knowledge/nodes/:id - Update node
  • DELETE /api/v1/knowledge/nodes/:id - Delete node
  • POST /api/v1/knowledge/edges - Create edge
  • DELETE /api/v1/knowledge/edges - Delete edge
  • GET /api/v1/knowledge/graph/statistics - Get statistics
