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.
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.
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 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:
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.
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.
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.
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.
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
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.
You can run the project using the following command:
This will start the iOS simulator and launch the app.
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.
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.
When you’ve designed and tested your app, use tools like Xcode and Android Studio to build and push it to app stores.
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.
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.
While there are many benefits for organizations to use React Native, there are also potential drawbacks. Some of the major obstacles include:
Absence of native functionality
While React Native gives you access to numerous native device capabilities and APIs, some of them may be unavailable or have restricted usefulness. This can be difficult for organizations that need unique app functionalities.
Issues with compatibility
React Native may not be compatible with all third-party libraries and frameworks, which can be difficult for organizations that rely on these tools in their development workflow.
Support for legacy systems is limited
Because React Native is a new technology, it may not be well-suited for enterprises that need to integrate with older legacy systems or technologies.
Developer recruitment and training
It can be difficult to find skilled React Native developers, and firms may need to invest time and resources in training their developers on this technology.
Debugging and testing
Debugging and testing React Native apps can be difficult because the technology is still emerging and developers may have limited resources and tools.
