🔴 Let's build a Full Stack Car Rental App with REACT NATIVE using Node.js | PostgreSQL

🚗 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. source code - https://sujan45.gumroad.com/l/rlhwio 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 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔥 FEATURES BUILT ✅ Full authentication flow with JWT + Refresh Token rotation ✅ 9 mobile screens with premium dark UI ✅ City and pickup location selection with search ✅ Date/time pickers for booking duration ✅ 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. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📚 WHAT YOU'LL LEARN How to structure a full stack project from scratch Setting up PostgreSQL with Prisma ORM Building secure JWT authentication with refresh tokens Designing REST APIs with Express and TypeScript Preventing race conditions with database transactions Building beautiful UIs with React Native + NativeWind State management with Zustand File-based navigation with Expo Router Implementing axios interceptors for auto token refresh Date/time pickers in React Native Bottom sheet modals Pull-to-refresh and tab navigation Production-grade error handling and logging ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💬 CONNECT WITH ME 🔔 Subscribe for more full stack tutorials:    / @sujananand6155   📸 Instagram: @sujananand 🙏 If you found this video valuable: 👍 LIKE the video 💬 COMMENT what feature you want next 🔔 SUBSCRIBE for more projects like this 📤 SHARE with someone learning full stack ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ #ReactNative #NodeJS #FullStack #PostgreSQL #Prisma #Expo #JavaScript #TypeScript #WebDevelopment #MobileApp #CarRental #JWT #FullStackDeveloper #CodingTutorial #LearnToCode
