🚀 Niche Marketplace - Quick Start Guide

What's Been Built

Your React Native mobile app now has a solid foundation with:

✅ Complete Project Structure

  • Organized folders for screens, components, services, store, types, utils, and navigation

✅ Authentication System

  • Login & Signup screens
  • Redux state management for auth
  • Session persistence
  • Role-based access control (Customer, Vendor, Admin)

✅ API Service Layer

  • Axios client with interceptors
  • Authentication token management
  • Ready for all endpoints (products, orders, cart, etc.)

✅ Navigation System

  • Role-based navigation (different UI for each user type)
  • Bottom tab navigation for each role
  • Stack navigation for auth screens

✅ Sample Screens

  • Customer: Home (products), Profile
  • Vendor: Dashboard with stats and quick actions
  • Admin: Dashboard with platform overview

✅ State Management (Redux)

  • Auth state slice
  • Products state slice
  • Cart state slice
  • Async API handling with thunks

✅ Type Safety

  • Full TypeScript types for all data models
  • User roles, products, orders, subscriptions, etc.

✅ Reusable Components

  • PrimaryButton, SecondaryButton, TextInput, ErrorMessage

🎯 Next Immediate Steps

1. Update API Configuration

Edit src/services/api.ts - Replace the API base URL:

const API_BASE_URL = 'https://your-api-endpoint.com/v1';

2. Run the App

cd F:\mobileapplication\nichexismarket
npm run android  # or npm run ios

3. Test Authentication

  • Try signing up with different roles (Customer/Vendor)
  • Login and see role-based navigation
  • Check that logout works

🔌 How to Add a New Screen

Step 1: Create the Screen File

// src/screens/customer/CartScreen.tsx
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
import { useSelector } from 'react-redux';
import { RootState } from '../../store';

export const CartScreen: React.FC<any> = ({ navigation }) => {
  const { cart, loading } = useSelector((state: RootState) => state.cart);

  return (
    <View style={styles.container}>
      <Text>Cart Screen</Text>
      {/* Your UI here */}
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
  },
});

Step 2: Add to Navigation

Edit src/navigation/RootNavigator.tsx:

<Tab.Screen
  name="Cart"
  component={CartScreen}
  options={{
    title: 'Cart',
    tabBarLabel: 'Cart',
    tabBarIcon: ({ color }) => <Text>🛒</Text>,
  }}
/>

Step 3: Add Redux Slice (if needed)

Create src/store/slices/[feature]Slice.ts following the pattern in cartSlice.ts

🧪 Testing Quick Commands

# Check for linting errors
npm run lint

# Run tests
npm run test

# Clear cache and reinstall
npm install

📚 Key API Endpoints (Backend Should Implement)

Authentication

  • POST /auth/login - Login
  • POST /auth/signup - Create account
  • POST /auth/logout - Logout

Products

  • GET /products - List products
  • GET /products/:id - Get product detail
  • POST /products - Create product (vendor only)
  • PUT /products/:id - Update product (vendor only)
  • DELETE /products/:id - Delete product (vendor only)

Orders

  • GET /orders - List user orders
  • GET /orders/:id - Get order detail
  • POST /orders - Create new order
  • PATCH /orders/:id/status - Update order status

Cart

  • GET /cart - Get cart
  • POST /cart/items - Add to cart
  • PATCH /cart/items/:id - Update cart item
  • DELETE /cart/items/:id - Remove from cart

Stores (Vendor)

  • GET /stores/:id - Get store detail
  • POST /stores - Create store
  • PUT /stores/:id - Update store

Admin

  • GET /admin/dashboard - Platform stats
  • GET /admin/vendors - List vendors
  • PATCH /admin/vendors/:id/approve - Approve vendor
  • PATCH /admin/vendors/:id/suspend - Suspend vendor

🎨 Styling Tips

The app uses React Native StyleSheet with:

  • Primary color: #FF6B6B (red)
  • Text color: #222 (dark gray)
  • Border color: #ddd (light gray)
  • Background: #f5f5f5 (very light gray)

Create consistent screens by following existing styles in HomeScreen.tsx, DashboardScreen.tsx, etc.

🐛 Troubleshooting

App won't start?

  1. Clear cache: npm run android or npm run ios
  2. Delete node_modules and reinstall: npm install
  3. Check API URL in src/services/api.ts

Redux not updating?

  1. Check Redux DevTools in browser (if available)
  2. Ensure you're using useDispatch<AppDispatch>() with proper typing
  3. Check that async thunks have .unwrap() call

Navigation issues?

  1. Ensure user role is set correctly after login
  2. Check RootNavigator.tsx logic
  3. Verify role values match UserRole enum

💡 Pro Tips

  1. Keep State in Redux - Use Redux for global state, local state for component-level UI
  2. Use TypeScript - Take advantage of type safety - it catches errors early
  3. Reuse Components - Create more components in src/components/ and reuse them
  4. Error Handling - Check API responses and display error messages to users
  5. Loading States - Show spinners while loading data from API
  6. Async Storage - Use for caching, preferences, etc.
