What problem does it solve? Connecting React or Flutter frontends to Kailash SDK workflows requires correct API client setup, state management, error handling, and type safety, which developers often implement inconsistently or incorrectly. ## Core Features & Use Cases - React Integration: Quick-start patterns for calling Kailash workflows from React using TanStack Query, React Flow workflow editors, Zustand state, and streaming responses. - Flutter Integration: HTTP client setup with Dio, Riverpod/Bloc state management, responsive layouts, form validation, and platform-specific code for mobile and desktop apps. - Architecture Guidance: Recommended stacks, backend architecture (Frontend → Nexus API → Kailash Workflows → DataFlow), and best practices for error handling, caching, and performance. - Use Case: A developer building a React dashboard that executes Kailash workflows through the Nexus API can follow the provided patterns to implement typed API clients, loading states, and real-time WebSocket updates. ## Quick Start Ask how to connect a React or Flutter app to a Kailash workflow through the Nexus API, including state management and error handling setup.
