Muhammadyasir678 The Evolution Of Todo App Fullstack Web Dev

name: fullstack-web-dev description: Build modern fullstack web applications using Next.js and FastAPI with clean architecture. Use for scalable production-ready web systems.

Fullstack Web Development

Instructions

1. Frontend (Next.js 16+)

   • Use App Router (app/ directory)
   • Server Components by default
   • Client Components only when required
   • Implement routing, layouts, and loading states
   • Use Tailwind CSS for styling
   • Ensure responsive, mobile-first design

2. Backend (FastAPI)

   • Build RESTful APIs using proper HTTP methods (GET, POST, PUT, DELETE)
   • Structure backend with routers, services, and models
   • Use SQLModel ORM for database interactions
   • Implement dependency injection for database sessions
   • Return standardized API responses and status codes

3. Database Layer

   • Define SQLModel models with clear relationships
   • Use migrations-friendly schema design
   • Separate data models and schemas when needed
   • Handle CRUD operations cleanly

4. Authentication & Security

   • Integrate Better Auth with JWT-based authentication
   • Protect routes using auth dependencies
   • Handle token issuance, refresh, and validation
   • Secure environment variables and secrets

5. Monorepo Management

   • Maintain clear separation between frontend/ and backend/
   • Share types or contracts where applicable
   • Use consistent naming and folder conventions
   • Support independent deployment of frontend and backend

Best Practices

• Follow clean code and separation of concerns
• Keep API contracts explicit and documented
• Use type safety on both frontend and backend
• Validate user input on server side
• Handle errors gracefully with meaningful messages
• Optimize for performance and scalability
• Follow REST standards and HTTP semantics
• Write reusable components and services
