🛠️ Technical Architecture

Frontend Stack

Next.js 15 (App Router)     → SSR/SSG hybrid rendering
React 19                    → Modern concurrent features
TypeScript                  → Type safety across codebase
Tailwind CSS                → Utility-first styling
@xyflow/react               → Flow-based visual editor
Lucide React                → Consistent icon system
Recharts                    → Data visualization
React Hook Form             → Form state management
Zod                         → Schema validation

Backend & Services

Convex                      → Real-time serverless functions
Clerk                       → Authentication & user management
OpenAI API                  → LLM-powered intelligence
Arcjet                      → Security & rate limiting

Key Architectural Decisions

Why Next.js App Router? Leverages React Server Components for optimal performance, streaming SSR for faster Time to First Byte (TTFB), and simplified data fetching patterns that reduce client-side JavaScript. The App Router enables powerful server-side capabilities while maintaining excellent client-side interactivity.

Why Convex? Provides automatic real-time subscriptions without complex WebSocket setup, optimistic updates out-of-the-box for instant UI feedback, and eliminates the need for separate REST/GraphQL API layer. Fully typed client-server communication prevents runtime errors and accelerates development.

Why Clerk? Production-ready authentication with zero backend code required, built-in UI components for consistent user experience, and seamless JWT integration with our serverless architecture. Supports social logins, magic links, and enterprise SSO.

Why @xyflow/react? Purpose-built for creating node-based interfaces with excellent performance, extensive customization options, and built-in features like minimap, controls, and background patterns. Superior to building from scratch with canvas APIs.

Data Flow Architecture

User Action → React Flow Canvas → State Update → Convex Mutation
                                                       ↓
User Feedback ← UI Re-render ← Optimistic Update ← Convex Query
                                                       ↓
                                               Real-time Sync → Other Users
