Act like a professional mobile app developer using Rocket.new to scaffold a fully functional React Native Expo application. Your task is to generate all code and structure required to build an app named "Maak" for ordering Gas cylinders and Diesel material.Objective:Build a React Native Expo application with a clean architecture, API-ready screens, and essential features, with every screen scaffolded and modularized for easy integration of real API endpoints.Step-by-step requirements:Step 1: App Configuration- App name: "Maak".- Use Expo with TypeScript.- Apply modular code structure, reusable components, and atomic design principles.- Prepare folder structure like: screens/, components/, services/, contexts/, and utils/.Step 2: Splash Screen- Implement a basic splash screen with the app logo.- Add a loading spinner and prepare the screen for future API readiness (e.g., check user session or fetch config).Step 3: Authentication Screen (Login/Register)- Create a combined Login/Register screen using phone number and username only.- No password, email, Google, or Apple login.- Prepare API-ready form handlers using placeholder functions such as authService.login() and authService.register().- Create services/authService.ts to handle future API logic (with placeholder URLs and logic).- After success, navigate to the main app.Step 4: Main App Navigation (Bottom Tabs)Use a Bottom Tab Navigator with 4 tabs, each screen ready for API integration:1. Home Tab (Gas & Diesel Products) - Display two sections: Gas Cylinders and Diesel Material. - Fetch product lists from placeholders: productService.getGasCylinders() and productService.getDieselMaterials(). - Prepare services/productService.ts with dummy API structure to allow plug-and-play with your API.2. Order Status Tab - Display list of orders and their statuses (e.g., Pending, Delivered). - Make screen ready for API integration: orderService.getUserOrders(). - Scaffold services/orderService.ts for future API fetch.3. Profile Tab - Display user’s current profile (username and phone). - Enable editing the username. - All data/actions should be ready to fetch/update via: userService.getProfile() and userService.updateProfile().4. Settings Tab - Toggle Dark Mode and Light Mode using context. - Logout button (clears user session context). - Language Switcher using i18next (Arabic and English). - Static views for "About Us" and "Privacy Policy" (can be converted to API-rendered content later). - Make logout ready with a call to authService.logout().Step 5: Internationalization- Implement i18n with support for Arabic and English.- Provide placeholder translation JSON files.- Language toggle should update app content dynamically.Step 6: Theming- Implement theme switcher (light/dark) using context/provider.- Apply consistent styling via a central theme object.Step 7: State Management- Use Context API or Zustand for global state (auth, theme, language).- Maintain user session across app and persist via AsyncStorage.Step 8: API Service Layer- In the services/ directory, create modular and replaceable files: - authService.ts - productService.ts - orderService.ts - userService.ts- Inside each, define functions with placeholder base URLs like https://your-api-url.com/endpoint.Step 9: Dummy Data and UX- Provide fallback data in the UI until API integration is live.- Keep UI simple, clean, and mobile-first.Take a deep breath and work on this problem step-by-step.
I'll help you build a complete React Native Expo application called "Maak" for ordering gas cylinders and diesel materials. Let me scaffold the entire application with a clean architecture and API-ready structure.

Installation Instructions
To get started with this Maak Gas & Diesel delivery app:
Install Expo CLI globally:
npm install -g @expo/cliCreate a new Expo project:
npx create-expo-app MaakApp --template typescript cd MaakAppInstall dependencies:
npm install @react-navigation/native @react-navigation/bottom-tabs @react-navigation/stack react-native-screens react-native-safe-area-context @expo/vector-icons @react-native-async-storage/async-storage i18next react-i18next zustand expo-splash-screen expo-status-bar- Replace the generated files with the code provided above
Start the development server:
npx expo start
Key Features Implemented:
✅ Complete App Structure - Modular architecture with proper folder organization ✅ Authentication System - Phone number + username login/register ✅ Bottom Tab Navigation - 4 main screens (Home, Orders, Profile, Settings) ✅ API-Ready Services - Placeholder service layer for easy API integration ✅ Internationalization - Arabic and English support with i18next ✅ Theme System - Light/Dark mode with context provider ✅ State Management - Zustand store for global state ✅ Persistent Storage - AsyncStorage for user session and preferences ✅ TypeScript Support - Full type safety throughout the app ✅ Mock Data - Dummy data for immediate testing and development
The app is now ready for API integration - simply replace the mock responses in the service files with actual API calls to your backend endpoints!
I understand you'd like to test the React Native Expo app, but I need to clarify something important: I can only generate and display code for web-based applications in my preview environment. React Native apps are designed to run on mobile devices or simulators, which I cannot directly execute or preview.
However, I can help you get the app running on your local machine! Here's exactly what you need to do:
Step-by-Step Setup Instructions
1. Prerequisites
Make sure you have Node.js installed on your computer. You can download it from nodejs.org.
2. Install Expo CLI
npm install -g @expo/cli3. Create the Project
npx create-expo-app MaakApp --template typescript
cd MaakApp4. Install Required Dependencies
npm install @react-navigation/native @react-navigation/bottom-tabs @react-navigation/stack react-native-screens react-native-safe-area-context @expo/vector-icons @react-native-async-storage/async-storage i18next react-i18next zustand expo-splash-screen expo-status-bar5. Install Expo Dependencies
npx expo install react-native-screens react-native-safe-area-context6. Replace Files
Copy all the code I provided above into the corresponding files in your project. The main files you need to create/replace are:
App.tsxapp.jsonsrc/screens/(all screen files)src/contexts/(context files)src/services/(service files)src/stores/authStore.tssrc/types/index.tssrc/utils/i18n.tssrc/locales/(translation files)
7. Start the Development Server
npx expo start8. Test the App
Once the server starts, you'll see a QR code. You can:
- On your phone: Download the "Expo Go" app and scan the QR code
- On computer: Press
ifor iOS simulator orafor Android emulator (requires Xcode/Android Studio) - Web browser: Press
wto run in web browser (limited functionality)
What You Can Test
Once running, you'll be able to test:
✅ Splash Screen - App loading with Maak branding ✅ Authentication - Login/Register with phone number and username ✅ Home Screen - Browse gas cylinders and diesel materials ✅ Orders Screen - View order history and status ✅ Profile Screen - Edit user profile information ✅ Settings Screen - Toggle dark mode, change language (Arabic/English), logout ✅ Navigation - Bottom tab navigation between all screens ✅ Theming - Switch between light and dark modes ✅ Internationalization - Switch between English and Arabic
Alternative: Web Preview
If you'd like to see a web-based version for quick preview (though it won't have full mobile functionality), I can create a Next.js version that demonstrates the same UI and features. Would you like me to do that instead?
Need Help?
If you run into any issues during setup, let me know the specific error messages and I can help troubleshoot!
The app is fully functional with mock data, so you can test all features immediately without needing a backend API.
