In the world of mobile app development, efficient cross-platform solutions are a holy grail. One such technology, React Native, stands out due to its capacity to render natively on both iOS and Android platforms. Invented by Facebook, this JavaScript framework has gained widespread popularity among developers and businesses alike. Here's why.
What is React Native?
React Native is a JavaScript framework for building mobile applications that run natively on both iOS and Android platforms. It’s an offshoot of React, Facebook’s JavaScript library for crafting engaging user interfaces. However, instead of targeting browsers like React does, React Native focuses on mobile platforms. The result? A seamless user experience and code reusability that hastens development timelines and reduces costs.
Building Blocks of React Native
In React Native, the building blocks are the native components. It wraps existing native code for user interface controls and exposes them to JavaScript. As a result, your React Native apps will render using real mobile UI components, not webviews, providing the same look and feel as any other mobile application.
React Native also taps into JavaScript and React, enabling you to compose a rich mobile UI from declarative components. If you're familiar with React, you'll be right at home with React Native.
Why Choose React Native?
One of the key advantages of React Native is Code Reusability. The same team can develop apps for both iOS and Android, leading to significant cost and time savings. More than that, up to 90% of the code can be shared between the two platforms.
React Native also boasts Community Support. As an open-source project, React Native is supported by a vibrant community of developers who continually contribute to making the framework better. This means you can leverage plenty of third-party plugins and libraries.
Performance is another area where React Native shines. Unlike hybrid frameworks that render code via webviews, React Native allows components to be rendered as native platform widgets, leading to improved performance.
Hot Reloading is a distinctive feature that increases development speed. This feature refreshes the UI instantly as developers adjust the code, allowing them to see changes in real time.
React Native in the Real World
Major corporations use React Native. Facebook, of course, uses it for their Ads Manager app. Instagram, after being acquired by Facebook, integrated React Native into their existing native app for push notifications and saved posts.
Other notable mentions include Walmart, which used React Native to improve performance of their app, and Bloomberg, which developed their consumer mobile app using this technology.
Starting with React Native
To start with React Native, you need to have Node.js and npm (node package manager) installed on your computer. Also, install the Expo CLI, which helps you create and manage your React Native projects.
Create a new project with expo init AwesomeProject, navigate into the project using cd AwesomeProject, and start your app with npm start.
Conclusion
React Native is a revolutionary framework that is changing the landscape of mobile app development. Its ability to deliver native-like performance, coupled with significant time and cost savings, makes it an attractive choice for businesses and developers. Whether you are planning to build a new app or thinking about migrating an existing one, React Native could be a great choice.
