  • Explain authentication flow
  • Show database schema
  • Demonstrate API endpoints (maybe with Postman)

3. Frontend Walkthrough (5-7 min)

  • Show React component structure
  • Explain API integration
  • Show state management
  • Demonstrate user flow

4. Running the Application (5 min)

  • Start backend server
  • Start frontend
  • Register a new user
  • Add shoes
  • Delete shoes
  • Show data persistence

5. Code Highlights (5-7 min)

  • Authentication middleware
  • JWT token handling
  • Prisma query examples
  • React hooks usage
  • Error handling

6. Technical Summary (2-3 min)

  • Explain how the full stack works together
  • Highlight design decisions
  • Discuss scalability considerations
  • Answer any questions

🎤 Key Points to Communicate

Architecture

"I've used a clean, layered architecture with TypeScript throughout. The backend has typed routes that handle HTTP, typed controllers for request logic, and typed services for business logic and database operations. TypeScript provides compile-time type checking and better developer experience."

Authentication

"I implemented JWT-based authentication. When users register, their passwords are hashed with bcryptjs. On login, a JWT token is issued and stored in localStorage. All protected routes use middleware to validate this token."

Database

"I'm using Prisma ORM with SQLite for simplicity. Prisma provides type-safe queries and automatic migrations. The schema defines User and Shoe models with proper relationships."

Frontend

"The React app uses functional components with hooks. I created modular components - Login for auth, ShoeList for display, and AddShoeForm for adding shoes. The API service centralizes all HTTP calls with axios."

Security

"Passwords are hashed with bcryptjs, JWT tokens have expiration, protected routes require valid tokens, and CORS is configured to prevent unauthorized access."

Error Handling

"I've added try-catch blocks throughout, proper HTTP status codes, user-friendly error messages, and loading states for better UX."

🐛 Common Issues & Solutions

Port 3000 already in use?

# Change PORT in server/.env
PORT=3001

Cannot find module errors?

cd server && npm install
cd ../client && npm install

Database errors?

cd server
npx prisma generate
npx prisma migrate deploy

Frontend cannot connect to backend?

  • Check backend is running on port 3000
  • Check client/.env has correct API URL
  • Check CORS is enabled
