Steps To Build Shopify Mobile Store With React Native

Building a React Native mobile app for Shopify store involves several steps. Below is a step-by-step guide to help you create your Shopify mobile app using React Native: 

1. Set Up Your Development Environment

• Install Node.js (latest stable version).

Install React Native CLI if you want to use the CLI tool (alternatively, you can use Expo). npm install -g react-native-cli

• Install Android Studio and Xcode (if developing for iOS).

Install Expo (if using Expo for easier development). npm install -g expo-cli

• Install npm or yarn for package management.

2. Create a New React Native Project

Create a new React Native project using the CLI or Expo.

Using React Native CLI:

npx react-native init ShopifyMobileApp

cd ShopifyMobileApp

Using Expo:

expo init ShopifyMobileApp

cd ShopifyMobileApp

3. Set Up Shopify Store and Get API Credentials

• Go to the Shopify Admin Dashboard and create a new store (if you don’t already have one).
• Obtain your Shopify Store’s API credentials (API Key, API Password, and Storefront Access Token).
  • You need to create a private app in your Shopify store’s settings under Apps > Manage private apps.
• Shopify provides the Storefront API to access store data, including products, collections, and more.

 4. Install Dependencies

Install the necessary libraries to interact with Shopify, as well as libraries for navigation, state management, etc.

npm install axios react-navigation react-navigation-stack react-redux redux

• Axios: For making HTTP requests to the Shopify API.
• React Navigation: For navigating between screens.
• Redux: For managing global state, especially for managing cart data.

5. Connect to Shopify Store API

Create a file api.js (or a similar name) where you’ll define functions to interact with Shopify’s Storefront API.

import axios from ‘axios’;

const SHOPIFY_API_URL = ‘https://your-shopify-store.myshopify.com/api/2023-10/graphql.json’;

const SHOPIFY_ACCESS_TOKEN = ‘your-shopify-access-token’;

const getProducts = async () => {

  const query = `

    {

      products(first: 10) {

        edges {

          node {

            id

            title

            descriptionHtml

            variants(first: 1) {

              edges {

                node {

                  priceV2 {

                    amount

                    currencyCode

                  }

                  image {

                    src

                  }

                }

              }

            }

          }

        }

      }

    }

  `;

  

  try {

    const response = await axios.post(

      SHOPIFY_API_URL,

      { query },

      {

        headers: {

          ‘X-Shopify-Storefront-Access-Token’: SHOPIFY_ACCESS_TOKEN,

          ‘Content-Type’: ‘application/json’,

        },

      }

    );

    return response.data.data.products.edges;

  } catch (error) {

    console.error(‘Error fetching products:’, error);

  }

};

export { getProducts };

6. Create Screens for Your App

• Home Screen: Display a list of products.
• Product Detail Screen: Show details about a specific product.
• Cart Screen: Display the items in the cart and allow checkout.

Example of Home Screen (Products List):

import React, { useEffect, useState } from ‘react’;

import { View, Text, FlatList, TouchableOpacity, Image } from ‘react-native’;

import { getProducts } from ‘./api’;

const HomeScreen = ({ navigation }) => {

  const [products, setProducts] = useState([]);

  useEffect(() => {

    const fetchProducts = async () => {

      const data = await getProducts();

      setProducts(data);

    };

    fetchProducts();

  }, []);

  const renderItem = ({ item }) => (

    <TouchableOpacity onPress={() => navigation.navigate(‘ProductDetail’, { productId: item.node.id })}>

      <View>

        <Image source={{ uri: item.node.variants.edges[0].node.image.src }} style={{ width: 100, height: 100 }} />

        <Text>{item.node.title}</Text>

        <Text>${item.node.variants.edges[0].node.priceV2.amount}</Text>

      </View>

    </TouchableOpacity>

  );

 

  return (

    <FlatList

      data={products}

      keyExtractor={(item) => item.node.id}

      renderItem={renderItem}

    />

  );

};

 

export default HomeScreen;

7. Implement Navigation

Set up navigation between the Home screen, Product Detail screen, and Cart screen.

App.js:

import * as React from ‘react’;

import { NavigationContainer } from ‘@react-navigation/native’;

import { createStackNavigator } from ‘@react-navigation/stack’;

import HomeScreen from ‘./HomeScreen’;

import ProductDetailScreen from ‘./ProductDetailScreen’; // You need to create this screen

import CartScreen from ‘./CartScreen’; // You need to create this screen

const Stack = createStackNavigator();

export default function App() {

  return (

    <NavigationContainer>

      <Stack.Navigator initialRouteName=”Home”>

        <Stack.Screen name=”Home” component={HomeScreen} />

        <Stack.Screen name=”ProductDetail” component={ProductDetailScreen} />

        <Stack.Screen name=”Cart” component={CartScreen} />

      </Stack.Navigator>

    </NavigationContainer>

  );

}

8. Implement Cart and Checkout Logic

You will need to store the user’s cart items in Redux or Context API to manage the state across screens.

• Implement functions to add and remove items from the cart.
• Use Shopify’s Checkout API to create and manage the checkout process.

9. Test on Devices

• Run the app on an Android/iOS simulator or a physical device.

npx react-native run-android

npx react-native run-ios

• If using Expo:

expo start
