🚗 Built a complete production-grade self-drive car rental app called DriveIndia — inspired by Myles. Full stack with React Native frontend, Node.js + Express + PostgreSQL backend, JWT authentication, double-booking prevention, dynamic pricing, and 300+ cars across 3 cities.

In this video, I walk through everything end to end — from database design to security, from API routes to React Native screens. If you want to learn how to build a real-world full stack app, this is for you.

🛠️ TECH STACK

Frontend:
Expo React Native + TypeScript
NativeWind (Tailwind CSS for RN)
Zustand for global state
Expo Router (file-based routing)
Axios with auto-refresh interceptor
Expo SecureStore for token storage

Backend:
Node.js + Express + TypeScript
PostgreSQL 16 with Prisma ORM v7
JWT with refresh token rotation
Zod schema validation
Winston structured logging
bcryptjs password hashing
Helmet + CORS + Rate Limiting

Database:
7 tables (Users, RefreshTokens, Cities, Sublocations, Cars, Bookings)
3 cities, 75 pickup locations, 300 cars

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✅ Car listing with filters (fuel, transmission, seats)
✅ Sort by price or seats
✅ Full car detail page with specs and pricing
✅ Real-time double-booking prevention
✅ Dynamic pricing (hourly vs daily)
✅ Booking confirmation with full breakdown
✅ Animated success screen
✅ My Bookings with tabs (All/Confirmed/Active/Completed/Cancelled)
✅ Cancel booking with confirmation alert
✅ Pull to refresh
✅ Profile screen with stats
✅ Bottom tab navigation
✅ Auto token refresh on 401
✅ Secure storage for tokens
✅ 300 real cars with images from CarWale

🏗️ ARCHITECTURE HIGHLIGHTS

📌 Double-Booking Prevention
Used Prisma $transaction with three overlap conditions and an atomic re-check inside the transaction to prevent race conditions when two users tap Book at the same time.

📌 JWT Token Rotation
Refresh tokens stored in DB and rotated on every refresh — old token deleted, new one issued. Prevents replay attacks.

📌 Dynamic Pricing Engine
Bookings ≤ 12 hours use hourly rate, anything longer switches to daily pricing with ceiling rounding. KM limit scales with duration.

📌 Type Safety End to End
TypeScript on both frontend and backend. Prisma generates fully typed DB queries.

📌 Security Layers
Helmet (15 security headers), CORS restrictions, rate limiting per IP, Zod input validation, bcrypt password hashing with configurable rounds.
