What Is Mobile App Development With React Native?

Patrick Burnett

Mobile app development has seen a significant increase in demand in recent years. With the rise of smartphones, businesses are now investing more in mobile applications to reach out to their customers and offer them unique experiences. React Native is a popular technology for developing mobile applications that has gained traction due to its cross-platform capabilities.

What is React Native?
React Native is an open-source mobile application framework developed by Facebook. It allows developers to build native mobile applications using only JavaScript and React. Since the code can be reused across different platforms, it is an efficient way of creating both Android and iOS apps.

What are the benefits of using React Native?
One major advantage of using React Native is its ability to speed up the development process. The same code can be used for both iOS and Android, thus reducing development costs and time. Additionally, React Native offers a smooth and seamless user interface since it uses native components instead of web views.

Here are some other key benefits:

  • Hot Reloading: Developers can see changes made in real-time without rebuilding the entire app.
  • Third-party plugins: There are numerous third-party plugins available that can be easily integrated into a project.
  • Large community support: Since Facebook backs React Native, it has a large community of developers who constantly contribute to its growth.

How does React Native work?
React Native works by creating a bridge between JavaScript code and native platform components. It uses JavaScriptCore to execute the JavaScript code on the device while communicating with native modules through this bridge. This allows developers to write logic in JavaScript while still having access to all the capabilities that come with native components.

The Development Process

1. Installation

To start developing with React Native, you need Node.js and the React Native CLI installed on your system. You can install the CLI using npm, which is a package manager for Node.js.

2. Creating a Project

After installing the CLI, you can create a new project using the command “react-native init project-name”. This will create a new project with all the necessary files and folders.

3. Running the App

To run the app, navigate to the project directory and use “react-native run-android” or “react-native run-ios” depending on your Target platform.


React Native is an excellent choice for developers looking to build cross-platform mobile applications. Its ability to reuse code and provide a smooth user interface makes it a popular framework among developers worldwide. With its growing community support and constant updates, React Native is set to become even more popular in the future.
