How to Build a Shopping App Like Amazon By Using React Native Platform

By Softpulse Infotech, April 9th, 2021

More than half of the internet traffic is coming from mobile devices. The majority of mobile e-commerce traffic as well is coming from the smartphone. If mobile users are targeted right, then it can work as a notably good source of business revenue. And still, several e-commerce store owners are ignoring this platform. By giving reasons such as the high cost of development and maintenance, they are ignoring this platform. And believe us, they are losing out on the great opportunity. Here I would like to mention the excellent platform named React Native.

In the past few years, React Native has penetrated the mobile app development industry. Several giant brands have accepted this platform and created their apps using it. With React Native, the app development process gets pretty easy. The primary advantage of React Native is its cross-platform development capability. With React Native, there is no need for individual teams for different operating systems. With its cross-platform functionality, one team can write an app for all different OS. 

Shopify ecommerce development

In this article, we will talk about creating a basic eCommerce app like Amazon, with basic search and display results functionality. 

Let’s discuss the process in one by one steps.

Prerequisite

As a prerequisite, you should have at least some experience in writing the React app. There are several resources available online. You can start with them. If you prefer the videos over text, that is available too. You should be familiar with the basic principles of React. And more importantly, you should know the basic principle of developing an app. With React Native, you will also use a shared codebase for both the major platforms. Now let’s discuss the app development process step by step.

Basic concept

Before starting the app development process, let’s understand the working of React. You should know how JavaScript code converts into a native mobile app. The React Native runs on two threads, the Main thread & the JavaScript Thread. The main thread manages the user interface of your app. The main thread executes the codes written utilizing Android, Java, and Swift or Objective C. And the JavaScript thread executes the code on a separate JavaScript engine. 

For apps to work, both of these codes need to interact with each other. And for that to happen, the bridge is there. The bridge helps in data transactions between the main thread and JavaScript thread. Now, it’s time to write the app.

Connect phones using the Expo client app

Firstly, make sure to install the node in your system. And we are going to use the create-react-native-app (CRNA) tool for setting up the boilerplate. Now create a new React Native project. Start the new development server and print the QR code in your terminal. The next step is to install the Expo client app on your Android and iOS devices. Connect both the devices on the same wireless network as your PC. Open the project on your phone by scanning the QR code from the terminal. Now your app will look blank. You can run it through an emulator.

Debugging

Debugging helps a lot during the app development process. It helps in browsing the errors or console messages in the browser. And you should download the React native debugger. It offers the functionality of browsing through the component state and props tree. And it also helps you edit and browse the styles applied to the app’s components. 

Installing UI components

The React Native comes with several built-in components. The components help in creating a simple UI for your app. For the app, most of them use Elasticsearch. It is a NoSQL based database. Elasticsearch can search through a large amount of data in a short time. It can perform full-text searches on the whole database of documents(JSON objects). And it also examines each word in all the documents.

You can install the Elasticsearch server using its official installation guide. Now you need to create a data set for your e-commerce app. You may find it a bit hard, but don’t worry, we have got you covered. Clone this database using the clone this app button. And generate a credential for your app. Now connect the credentials with your app.

ReactiveSearch

ReactiveSearch is an open-source React and React Native library for Elasticsearch. ReactiveSearch helps in simplifying the entire process of connecting to an Elasticsearch index. And ReactiveSearch also helps in the interaction of the components. Install ReactiveSearch in your React Native project.

Search box for searching the products

Here we will use the Data Search component from ReactiveSearch. It helps us in searching across one or more fields in our datasheet. This DataSearch searches for the queries on data fields in the dataset. It goes inside the ReactiveSearch component and fetches all the necessary information.

Time to display the search results

To display the search result, we will use the ReactiveList component from ReactiveSearch. The props such as dataField, react, and onData have their individual functions. The DataField orders result using the name field. The react specifies the queries according to the currently selected value of the search box. When a new input is added in the search box, it automatically creates the new query. Hence, there is no need to write a manual query for any UI components. OData renders the list of the components.

The final result

After applying some components and styling, our React Native e-commerce app is ready. This was a short tutorial on creating an e-commerce app with basic search and list functionality.
