Deliveroo Food Ordering Clone with React Native (Expo Router, Zustand, Reanimated, Google API)

Introduction

In this tutorial, we will replicate the Deliveroo food ordering application using React Native, leveraging modern packages such as Expo Router, Zustand for state management, and Reanimated for animations. We will also integrate Google Maps API to enhance our application. By the end of this guide, you will have a functional food ordering app that demonstrates these technologies in action.

Step 1: Set Up Your Development Environment

• Install Node.js if you haven't already.
• Install Expo CLI by running:

  npm install -g expo-cli
  

• Create a new Expo project:

  expo init deliveroo-clone
  

• Navigate to your project directory:

  cd deliveroo-clone
  

Step 2: Install Required Packages

To replicate the functionalities, you need to install the following packages:

• Expo Router
• Zustand for state management
• Reanimated for animations
• React Navigation
• Google Maps API

Run the following command to install them:

npm install @react-navigation/native @react-navigation/native-stack zustand react-native-reanimated react-native-maps

Step 3: Create a Custom Header

• Define a custom header component to enhance UI.
• Create a new file called CustomHeader.js in your components folder.
• Implement the header with navigation options.

Example code snippet:

import React from 'react';
import { View, Text, Button } from 'react-native';

const CustomHeader = ({ title, navigation }) => {
  return (
    <View>
      <Text>{title}</Text>
      <Button title="Go Back" onPress={() => navigation.goBack()} />
    </View>
  );
};

export default CustomHeader;

Step 4: Implement a Bottom Sheet

• Use a bottom sheet to display additional options or information.
• Install the necessary library if needed.
• Create a BottomSheet component.

Step 5: Create Modal Page with Reanimated

• Utilize Reanimated for smooth modal transitions.
• Define the modal component and use animation hooks for effects.

Example structure:

import Animated, { Easing } from 'react-native-reanimated';

const ModalPage = ({ visible }) => {
  const translateY = new Animated.Value(0);
  // Logic for animation
};

Step 6: Integrate Google Maps API

• Set up Google Maps in your React Native application.
• Obtain an API key from Google Cloud Platform.
• Create a Map component to display locations.

Sample code:

import MapView from 'react-native-maps';

const MapComponent = () => {
  return (
    <MapView style={{ flex: 1 }} />
  );
};

Step 7: Implement Horizontal Scrolling

• Allow users to scroll through food categories horizontally.
• Use a FlatList component with horizontal layout.

Step 8: Create a Parallax Header Image

• Design a parallax effect on the header image as users scroll.
• Utilize the ScrollView component and adjust styles based on scroll position.

Step 9: Set Up Section List

• Use a SectionList to organize food items into categories.
• Define sections and render items accordingly.

Step 10: Implement Sticky Segments

• Create sticky headers for your sections using the SectionList component.

Step 11: Enhance Modals with Animations

• Add animations to modal components for better user experience.
• Use Reanimated to control modal visibility and animations.

Step 12: Manage State with Zustand

• Implement Zustand for global state management.
• Create a store to manage food items, cart, and user data.

Example of a Zustand store:

import create from 'zustand';

const useStore = create(set => ({
  cart: [],
  addToCart: item => set(state => ({ cart: [...state.cart, item] })),
}));

Conclusion

In this tutorial, you learned how to build a Deliveroo-like food ordering app using React Native, incorporating various modern technologies. You set up your development environment, installed necessary packages, and created essential components such as a custom header, bottom sheet, and Google Maps integration. Moving forward, you can enhance the app by adding features like user authentication and payment processing. Happy coding!
