A feature flag management system built on Cloudflare Workers with React frontend. Designed as a template for clean, layered architecture patterns.

npm install ./bin/dev # Visit http://localhost:8787

Clean layered design with type-safe contracts:

Frontend (React + TanStack Query) → Service (HTTP API) → Core (Business Logic) ← Storage (Durable Objects) 

• Pure API client functions (framework agnostic)
• Shared TypeScript contracts between frontend/backend
• TanStack Query for declarative data fetching
• Individual route handlers for clear API organization

./bin/dev # Start local development ./bin/test # Run tests  ./bin/check # Type checking ./bin/lint # Code linting ./bin/format # Code formatting ./bin/build # Production build ./bin/deploy # Deploy to Cloudflare

This project serves as a template for similar Cloudflare Workers applications. The architecture patterns can be adapted for different domains (users, orders, etc.).
