WorkflowUI Quick Start Guide

🚀 Getting Started in 5 Minutes

Prerequisites

• Node.js 18+ installed
• Python 3.9+ installed
• Port 3001 (frontend) and 5000 (backend) available

---

Option 1: Full Stack (Frontend + Backend)

Terminal 1 - Start Backend

cd workflowui/backend
pip install -r requirements.txt
python3 server_sqlalchemy.py

Expected output:

Starting WorkflowUI Backend on 0.0.0.0:5000
Database: sqlite:///workflows.db
 * Running on http://0.0.0.0:5000

Terminal 2 - Start Frontend

cd workflowui
npm install
npm run dev

Expected output:

✓ Ready in 1085ms
Local: http://localhost:3001

Terminal 3 - Test Backend (Optional)

# Health check
curl http://localhost:5000/api/health

# List workspaces
curl 'http://localhost:5000/api/workspaces?tenantId=default'

Open in Browser

• Frontend: http://localhost:3001
• Backend: http://localhost:5000

---

Option 2: Frontend Only (Mock Data)

cd workflowui
npm run dev

Browser automatically opens to http://localhost:3001 with local IndexedDB data.

---

Option 3: Docker (Full Stack)

# Build and run everything
docker-compose up

# Or just the backend
docker-compose up -d backend

# Or just the frontend
docker-compose up -d frontend

Then open http://localhost:3001

---

🧪 Testing the API

Create a Workspace

curl -X POST http://localhost:5000/api/workspaces \
  -H "Content-Type: application/json" \
  -d '{
    "id": "ws-1",
    "name": "My First Workspace",
    "tenantId": "default",
    "color": "#1976d2"
  }'

Create a Project

curl -X POST http://localhost:5000/api/projects \
  -H "Content-Type: application/json" \
  -d '{
    "id": "proj-1",
    "name": "AI Workflows",
    "workspaceId": "ws-1",
    "tenantId": "default",
    "color": "#ff6b6b"
  }'

Get Project Canvas Items

curl http://localhost:5000/api/projects/proj-1/canvas?tenantId=default

Add Workflow to Canvas

curl -X POST http://localhost:5000/api/projects/proj-1/canvas/items \
  -H "Content-Type: application/json" \
  -d '{
    "id": "card-1",
    "workflowId": "workflow-123",
    "position": {"x": 100, "y": 100},
    "size": {"width": 300, "height": 200},
    "zIndex": 0,
    "color": "#4CAF50"
  }'

🎯 Main Features

Frontend

• ✅ Infinite canvas with zoom/pan
• ✅ Workspace and Project management
• ✅ Workflow cards with drag-and-drop
• ✅ Real-time collaboration setup
• ✅ Settings (Canvas, Security, Notifications)
• ✅ Material Design 3 UI

Backend

• ✅ RESTful API (28 endpoints)
• ✅ SQLAlchemy ORM
• ✅ Multi-tenant support
• ✅ Proper database indexing
• ✅ CRUD operations for all entities

🧬 Architecture Highlights

Three-Layer Hierarchy

Workspace (top level)
  └── Project (grouping)
      └── Workflow Cards (spatial canvas items)
          └── Workflow Editor (existing React Flow)

Modular Component Design

• All components: <150 LOC (single responsibility)
• All hooks: Focused business logic
• Composition pattern: Complex hooks built from simple ones
• Barrel exports: Clean import statements

State Management

• Redux: Global state (workspaces, projects, canvas)
• IndexedDB: Offline persistence + sync queue
• Redux Slices: workspaceSlice, projectSlice, canvasSlice, etc.

---

🔧 Customization

Add a New Hook

// src/hooks/useMyFeature.ts
import { useSelector, useDispatch } from 'react-redux';

export function useMyFeature() {
  const dispatch = useDispatch();
  const state = useSelector(s => s.myFeature);

  const doSomething = useCallback(() => {
    dispatch(myAction());
  }, [dispatch]);

  return { state, doSomething };
}

Add a New Component

// src/components/MyComponent/MyComponent.tsx
import { Box, Button } from '@mui/material';
import styles from './MyComponent.module.scss';

export function MyComponent() {
  return (
    <Box className={styles.container}>
      <Button variant="contained">Click me</Button>
    </Box>
  );
}

Add a New API Endpoint

# backend/server_sqlalchemy.py
@app.route('/api/my-endpoint', methods=['POST'])
def my_endpoint():
    data = request.json
    tenant_id = request.args.get('tenantId', 'default')

    # Your logic here

    return jsonify({'success': True})

🚨 Troubleshooting

Port Already in Use

# Kill existing process
lsof -i :5000      # Find process on port 5000
kill -9 <PID>      # Kill process

# Or use a different port
# Edit backend/server_sqlalchemy.py, change port in app.run()

Database Issues

# Clear database and reinitialize
rm -f backend/workflows.db
python3 backend/server_sqlalchemy.py

Build Errors

# Clear build cache
rm -rf .next node_modules
npm install
npm run build

🎓 Learning Path

1. Start: Read this file
2. Explore: Check src/components/ directory structure
3. Understand: Look at src/hooks/index.ts to see all available hooks
4. Learn: Study one hook file (e.g., useWorkspace.ts)
5. Build: Create your own component using existing hooks
6. Test: Use API endpoints to persist data

💡 Pro Tips

• Fast Development: Use npm run dev for hot reloading
• Type Safety: All code uses TypeScript strict mode
• Easy Debugging: Redux DevTools works with useSelector
• Clean Code: All files <150 LOC, single responsibility
• Reusable: All hooks exported, easy to combine
