Extending the Horizons of Mobile App Development with React Native

In the rapidly evolving world of mobile app development, React Native emerges as a beacon of efficiency and cross-platform compatibility. As a dynamic framework that allows developers to build mobile applications using JavaScript, React Native stands out for its ability to compile native app components, enabling the development of apps for both iOS and Android with a single codebase.

This revolutionary approach not only accelerates the development process but also ensures a seamless user experience across multiple platforms. Saigon Digital, a leading digital solutions provider, leverages React Native to redefine mobile app development, emphasising innovation, efficiency, and an exceptional user experience.

The React Native Edge: A Saigon Digital Perspective

Saigon Digital adopts React Native for its distinct advantages in creating robust, market-responsive apps. The framework’s efficiency stems from its live reloading feature, which allows developers to immediately see the results of the latest changes, thereby significantly reducing development time. Moreover, React Native’s focus on UI renders highly responsive interfaces, ensuring a smooth and immersive user experience. Saigon Digital harnesses these strengths to deliver superior digital products that stand out in a competitive marketplace.

Bridging the gap between Development Speed and User Experience

One of the core reasons Saigon Digital champions React Native is its unique ability to balance rapid development cycles with delivering high-quality user experiences. The framework’s component-based structure enables developers to build apps with a hot reloading feature, facilitating quicker iterations. This means that Saigon Digital can bring products to market faster without compromising on the quality of the user interface or the overall app performance.

Navigating Challenges with Expertise

While React Native offers numerous benefits, navigating its landscape comes with its own set of challenges. These include understanding the nuances of native modules for advanced functionalities and managing app performance for complex applications. Saigon Digital, with its seasoned team of developers, navigates these challenges with strategic expertise and innovative solutions. By continuously learning and adapting to the latest React Native updates, Saigon Digital ensures that its apps remain cutting-edge, reliable, and scalable.

Empowering Businesses with React Native Solutions

Saigon Digital specialises in React Native development, empowering businesses to reach their digital transformation goals. From startups launching their first app to enterprises enhancing their mobile presence, we craft tailored solutions aligned with strategic objectives. Our client-centric approach has driven successful app deployments across diverse industries like e-commerce, healthcare, education, and entertainment.

React Native implementation at Saigon Digital Case Studies 

At Saigon Digital, we successfully launched our first React Native application named Viking Cup to the Google Store and IOS App Store 

Here is what we did to leverage Viking Cup App with React Native!

Expo Go

A free, open-source sandbox for learning and experimenting with React Native on Android and iOS devices

When you run npx expo start in your project, Expo CLI starts a development server and generates a QR code. Expo Go is available on Google Play and App store, download it and preview your app in the development environment. On Android, you can open the Expo Go app and scan the QR code to connect to the dev server. On iOS, use the device’s camera to scan the QR code.

You can now preview the app via Expo Go

File-based router

Expo routers enable developers to organise the file-base route, which allows us to manage navigation between screens in your app

Here is the Viking Cup codebase of the route architect:

React Navigation

React Navigation provides solutions for transitioning between screens and managing navigation history. It provides a consistent look and feel on both iOS and Android, while also allowing for platform-specific customization when needed.

Here is the code block for implementing React Navigation

import { createMaterialTopTabNavigator } from "@react-navigation/material-top-tabs";


const Tab = createMaterialTopTabNavigator<Screens>();


 	<Tab.Navigator
         screenOptions={{
           tabBarScrollEnabled: true,
           tabBarActiveTintColor: COLORS.PRIMARY.WHITE,
           tabBarInactiveTintColor: COLORS.PRIMARY.WHITE,
           tabBarStyle: {
             marginHorizontal: 16,
             backgroundColor: COLORS.PRIMARY.BLACK,
           },
           tabBarIndicatorStyle: {
             height: 2,
             backgroundColor: COLORS.PRIMARY.YELLOW,
           },
           tabBarGap: 16,
           tabBarLabelStyle: {
             fontFamily: "gotham",
             fontSize: 10,
             lineHeight: 16,
           },
           tabBarLabel(props) {
             return (
               <Text
                 {...props}
                 {...TextSizes.body}
                 fontFamily={props.focused ? "gothamMedium" : "gotham"}
                 width="100px"
                 textAlign="left"
               />
             );
           },
           tabBarItemStyle: {
             padding: 0,
             paddingBottom: 16,
             flexDirection: "row",
             alignItems: "flex-start",
             minHeight: 0,
             width: "auto",
           },
         }}
       >
         {days
           ?.filter((d) => Object?.keys(d?.fields)?.length)
           ?.map((day) => (
             <Tab.Screen
               options={{
                 title: format(
                   new Date(day?.fields?.Date ?? ""),
                   "EEE, dd MMM"
                 ),
               }}
               key={day?.fields?.Date}
               name={day?.id as "DateScreen"}
               component={DateScreen}
               initialParams={{
                 day: day?.fields,
                 placeholder: longestHeading,
               }}
             />
           ))}
       </Tab.Navigator>

And here is the result: when click on each navigation item, it will redirect to relevant screen

Conclusion

React Native is a popular framework for building mobile applications, and it comes with several advantages as well as some trade-offs:

Advantages:

  • Cross-Platform Development: React Native allows you to write your app’s code once and deploy it on both iOS and Android, which can lead to significant time and cost savings.
  • JavaScript and React Ecosystem: It leverages JavaScript and React, which have large communities and ecosystems. This means a wealth of libraries and tools are available to developers.
  • Live Reloading/Hot Reloading: React Native’s live and hot reloading features make it possible to immediately see the result of the latest change.
  • Native Feel: By using native components, React Native apps maintain the look and feel of traditional native apps.
  • Community and Support: React Native has strong community support, which means a lot of documentation, forums, and third-party tools are available.
  • Expo Integration: For projects using Expo, the development and deployment process is simplified, providing a set of tools and services that can expedite development.

Trade-offs:

  • Native Code Interoperability: Some features may still require native code, which can necessitate having a team member familiar with iOS and Android native development.
  • Performance Overhead: For apps with highly intensive computational tasks or needing fine-tuned optimisation, React Native might not match the performance of a fully native app.
  • App Size: React Native apps can be larger compared to native apps, although improvements and strategies are available to mitigate this.
  • Upgrades and Maintenance: React Native evolves quickly, and sometimes breaking changes can make the upgrade process challenging.
  • Dependency on Third-Party Libraries: While the rich ecosystem is an advantage, it also means that projects can become dependent on third-party libraries that may not be maintained over time.
