ReactNode.jsn8n APIOpenAIFlow Builder
Problem
Creating complex automation workflows requires technical expertise and time-consuming manual configuration.
Solution
Built an intuitive visual flow builder with AI-powered natural language processing that generates n8n workflows instantly from chat descriptions.
Results
- Generate complete automation workflows in seconds
- Natural language interface for non-technical users
- Seamless n8n integration for enterprise automation
- Visual flow builder with drag-and-drop simplicity
- AI-powered workflow optimization suggestions
Tech stack
Frontend
- React 18 + TypeScript (Vite)
- React Flow / @xyflow/react (graph editor)
- Zustand (state)
- Zod (schema validation)
- Tailwind CSS + Headless UI
- dnd-kit (drag & drop)
- React Router
- Vitest + Testing Library
Backend
- Python FastAPI (API)
- Uvicorn
- PostgreSQL + SQLAlchemy 2
- Redis + RQ (workers/queues)
- httpx + Tenacity (resilient I/O)
- Pydantic v2
- OpenAI integrations
- n8n API client
Infrastructure
- Docker Compose (local stack)
- Services: Postgres, Redis, n8n, MinIO, Backend, Worker, Frontend
- Object storage via MinIO
Key challenges
- Graph-to-workflow translation with strict typing and safe execution mapping to n8n
- Realtime streaming across nodes with backpressure, retries, and reconnection handling
- Scalable state persistence and template versioning for large graphs
- Performance in large canvases: virtualization, zoom/pan smoothness, and memoized renders
- Secure integration with external APIs (n8n/OpenAI) and key management
Future plans
- Multi-tenant workspaces with RBAC, audit logs, and org policies
- Observability: Sentry + tracing/metrics for node execution and API hops
- Queue scale-out: Redis cluster today; evaluate Celery/RabbitMQ or NATS/Kafka later
- Plugin SDK and template marketplace for custom nodes
- Vector-store adapters (Pinecone/Chroma) with managed embeddings pipelines
- Realtime collaboration (CRDT/Yjs) with presence and conflict resolution
These upgrades harden reliability, enable enterprise governance, and open ecosystem growth via plugins and templates, while improving UX with realtime collaboration and deep observability.
