React Native is the second most popular cross-platform mobile app development framework and holds the sixth rank among all development frameworks with a market share of 38%.
Since its creation, React Native has been on an upward trend, with more and more developers and businesses opting to use it as their primary framework for creating mobile applications due to its reliability and scalability.
In this blog, we will uncover various aspects of React Native app development, from how to use and benefits to comparison with other cross-platform app development frameworks.
What is React Native App Development?
React Native is an open-source cross-platform mobile app development framework developed by Facebook that enables developers to build native-like mobile apps by leveraging the React.js library.
Instead of web-based components, React Native app development employs native components, hence providing a better app performance. React Native also boasts a large developer community, that builds third-party plugins, integrations, and libraries to extend its functionalities and assist other developers.
What’s New in the React Native Ecosystem
The React Native ecosystem is always changing, with new updates, tools, and features coming out all the time. In case you’re interested in what’s new in the React Native ecosystem, here you go:
- React Native 0.64: React Native released version 0.64 with various new features, improvements, and bug fixes. Hermes runtime configuration, accessibility improvements, and iOS and Android components are important features.
- Expo SDK 43: Expo SDK is a popular React Native app development and deployment toolkit. SDK 43 supports iOS 15, Android 12, and TypeScript 4.4.
- React Native Navigation v6: A popular React Native navigation library. v6 adds stack presentation, a tab bar component, and performance improvements.
- React Native Firebase: React Native Firebase integrates Firebase, Google’s mobile developer platform, easily. The latest upgrades support Firebase Authentication v9, Performance Monitoring, and ML Kit.
- React Native CLI: This command-line interface builds and manages React Native projects. The latest updates enhance TypeScript support, project initiation, and third-party integration.
The Architecture of React Native
React Native adheres to a unidirectional data flow design, meaning that data travels in a single path via the application’s components. The architecture is based on the Facebook-developed Flux architectural pattern.
The primary components of React Native are:
- View: This component is in charge of displaying the user interface. It also can have additional elements like text and pictures.
- Props: They are the data supplied to a child component by its parent. They cannot be altered within the component as they are immutable.
- State: It is a component’s internal data. It is modifiable by the component itself, and when it is, the component is re-rendered.
- Redux: It is a library for state management that is compatible with React Native. It keeps the application state in a single store, from which the components can access the state.
- Actions: They are events that initiate state changes within an application. These are sent to the store, which then updates the state and re-renders the components.
- Reducers: They are functions that manage activities and change the state of the application.
React Native employs a Virtual DOM (VDOM) to efficiently update the user interface. It is a lightweight clone of the actual DOM that determines the least number of updates required to update the user interface. This makes React Native apps more efficient and quicker.
How is React Native Better Than Flutter For App Development?
Both React Native and Flutter are well-known cross-platform mobile app development frameworks for developing. Although they have some similarities, they also have substantial differences. Here are some important distinctions between React Native app development and Flutter app development
React Native use native components, whereas Flutter employs its own collection of widgets. Native components offer superior performance and a more consistent user experience, whereas Flutter widgets offer greater customization and flexibility.
For each platform, React Native requires a distinct development environment, such as Xcode for iOS and Android Studio for Android. Flutter offers a unified development environment across both platforms.
React Native supports hot reloading, which allows developers to observe changes in the app without having to rebuild or restart the app. Flutter has a similar functionality called “hot reload,” although it isn’t as fast as React Native
Because React Native has a larger and more established developer community, it has access to a broader choice of tools and third-party libraries. The Flutter community is fast increasing, yet it is still young in comparison to React Native.
Compared to React Native, Flutter has better performance because it compiles code to native ARM machine code, while React Native uses a bridge to talk to native components.
Difference between React Native App Development and Xamarin App Development?
React Native and Xamarin are both popular cross-platform mobile app frameworks. Here are the key differences between React Native app development and Xamarin app development:
React Native use native components, whereas Xamarin employs its own set of controls. Xamarin controls are more customizable, but native components run better and offer a more consistent user experience.
Xcode for iOS and Android Studio for Android are required for React Native development. Xamarin’s cross-platform programming environment simplifies development.
React Native has a larger developer community with more tools and third-party libraries. Xamarin’s community is powerful but smaller than React Native’s.
As Xamarin converts code to native machine code, it outperforms React Native, which uses a bridge to interface with native components.
Xamarin requires a license for full functionality, which might be expensive for small enterprises and individual developers. Smaller teams can use React Native because it’s open source.
How to Start React Native App Development?
- Install Node.js
React Native can’t run without Node.js and the Node Package Manager (npm) is installed. Node.js can be downloaded from its official website and set up in a matter of minutes if you read and follow the instructions carefully.
- Install the React Native CLI
React Native includes a command-line interface (CLI) tool for creating and managing projects. You can install it in your terminal by typing the following command:
npm install -g react-native-cli
- Start a new project
The react-native init command can be used to create a new React Native project. For instance, you can enter this command in the terminal to initiate the creation of a new project with the name “MyApp”:
react-native init MyApp
This will create a new project with the basic file structure and dependencies.
- Run the project
You can run the project using the following command:
This will start the iOS simulator and launch the app.
- Write the code
You can now begin developing your app’s code by making use of React Native’s APIs and components. React Native comes with a set of fundamental components that you can use to design your user interface, including text, image, view, ScrollView, and others.
- Debugging and testing
You can test and debug your app using the React Native development tools. For example, you can analyze the component hierarchy and state using the React Native Debugger tool, and log warnings and errors using the console.
- Create and deploy
When you’ve designed and tested your app, use tools like Xcode and Android Studio to build and push it to app stores.
What is the Difference between React Native App Development For Android and iOS?
While React Native allows for the creation of cross-platform mobile applications, development for the Android and iOS platforms differs. Here are some of the notable differences:
React Native includes a set of UI components that may be used to create applications. However, the UI components for Android and iOS differ slightly. Developers must verify that the application’s UI components are compatible with both platforms.
Android and iOS have platform-specific APIs that the other platform does not have. While React Native gives access to the majority of the core APIs, developers may need to leverage platform-specific APIs to provide platform-specific functionality in some cases.
Because the styling for the Android and iOS platforms changes greatly, developers must ensure that the application’s design and layout adhere to the platform-specific requirements. React Native allows developers to easily generate platform-specific styles by providing a means to declare styles for both platforms.
React Native includes a navigation library that allows developers to design screen navigation. The navigation styles, however, change across Android and iOS. Developers must ensure that the navigation styles follow platform-specific rules.
Debugging React Native apps for Android and iOS differ differently. While both platforms include debugging tools, the debugging process differs. To effectively debug apps, developers must be familiar with platform-specific debugging tools.
How can Businesses Benefit From React Native App Development?
React Native offers numerous benefits to businesses wishing to develop mobile applications. Among the primary benefits are:
Using React Native, developers can create apps for both the iOS and Android platforms using a single codebase. Developers can save time and money by not having to design different codebases for each platform.
Reduced development cycles
The hot reloading feature of React Native allows developers to see changes in the app instantaneously, without having to rebuild or restart the app. This can hasten the development process and shorten the time to market.
Developers can save time and energy by reusing code between projects, thanks to React Native’s modular design and component-based architecture.
React Native renders the user interface using native components, which gives greater performance than hybrid application development frameworks that rely on web-based components.
The modular architecture of React Native enables businesses to easily extend their apps, adding new features and capabilities without having to completely rewrite the app.
Large developer community
React Native offers a huge and active developer community that provides access to a variety of resources, tools, and third-party libraries that can expand the functionality of an app.
