Project Implementation

Architecture Overview

This project follows a clean architecture pattern with the following structure:

• src/ - Main source directory
  • components/ - Reusable UI components (e.g. Button, Typography, Select, Card)
  • screens/ - Screen components (e.g. HomeScreen, ProductDetailsScreen, CartScreen)
  • navigation/ - Navigation configuration (e.g. AppNavigator, CollectionStackNavigator)
  • services/ - API and business logic (e.g. api, cart)
  • state/ - State management - React Context (e.g. CartContext)
  • types/ - TypeScript type definitions (e.g. Product, CartItem)
  • utils/ - Helper functions and utilities (e.g. formatCurrency)

Tech Stack

• Framework: Pure React Native (No Expo)
• Language: TypeScript
• State Management: [React Context]
• Navigation: React Navigation v6
• API Communication: [Mocked data]
• Testing: Jest & React Native Testing Library
• Code Quality: ESLint, Prettier

Development Setup

Note: Make sure you have completed the Set Up Your Environment guide before proceeding.

Step 1: Start Metro

First, you will need to run Metro, the JavaScript build tool for React Native.

To start the Metro dev server, run the following command from the root of your React Native project:

# Using npm
npm start

# OR using Yarn
yarn start

Step 2: Build and run your app

With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:

Android

# Using npm
npm run android

# OR using Yarn
yarn android

iOS

For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).

The first time you create a new project, run the Ruby bundler to install CocoaPods itself:

bundle install

Then, and every time you update your native dependencies, run:

cd ios
bundle exec pod install

For more information, please visit CocoaPods Getting Started guide.

# Using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.

This is one way to run your app — you can also build it directly from Android Studio or Xcode.

Step 3: Modify your app

Now that you have successfully run the app, let's make changes!

Open App.tsx in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by Fast Refresh.

When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload:

• Android: Press the R key twice or select "Reload" from the Dev Menu, accessed via Ctrl + M (Windows/Linux) or Cmd ⌘ + M (macOS).
• iOS: Press R in iOS Simulator.
