├──────────────────────────────┬──────────────────────┤
│  Canvas Area (flexible)      │  Edit Panel (400px)  │
│                              │                      │
│  [+HTTP] [+Script] [+Cond]   │  Node Configuration  │
│                              │                      │
│  ┌───────┐ ┌───────┐        │  Label: [_____]      │
│  │Node 1 │ │Node 2 │        │  Type:  [HTTP▼]      │
│  │ HTTP  │ │Script │        │                      │
│  └───────┘ └───────┘        │  URL:   [_____]      │
│                              │  Method:[GET ▼]      │
│  ┌───────┐ ┌───────┐        │                      │
│  │Node 3 │ │Node 4 │        │  [Save] [Delete]     │
│  │ Delay │ │ Loop  │        │                      │
│  └───────┘ └───────┘        │                      │
└──────────────────────────────┴──────────────────────┘
```

**Node Types:**
1. **HTTP Request** - REST API calls with headers/body
2. **Script Execution** - Run scripts by path or inline
3. **Condition** - Conditional branching logic

  description TEXT,
  status INTEGER DEFAULT 0,
  workflowGraph JSON,
  createdAt DATETIME NOT NULL,
  updatedAt DATETIME NOT NULL
);
```

## Future Enhancements (Optional)

   - Allow manual node repositioning on canvas
   - Save x/y coordinates in node data

3. **Workflow Execution Engine**
   - Backend execution engine to run workflows
   - Queue management for concurrent executions

4. **Real-time Monitoring**
   - Live execution status updates
   - Detailed execution logs per node

5. **Workflow Templates**
   - Pre-built workflow templates for common tasks
   - Template marketplace/library

6. **Import/Export**
   - Export workflows as JSON
   - Import workflows from files

7. **Advanced Validation**
   - Detect circular dependencies
   - Validate node connections
   - Required field validation

8. **Version Control**
