# 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:

```bash
pnpm add better-auth better-auth-credentials-plugin
```

### ReactFlow Dependencies

Verify that `@xyflow/react` is installed:

```bash
pnpm add @xyflow/react
```

### Mermaid Dependency

Verify that `mermaid` is installed:

```bash
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
