The recommended way to create a React Native application in IntelliJ IDEA is to use a dedicated project generator, for example, the React Native CLI. Make sure the JavaScript and TypeScript and JavaScript Debugger required plugins are enabled on the Settings | Plugins page, tab Installed, see Managing plugins for details. Make sure you have Node.js on your computer. IntelliJ IDEA also provides code completion for React and Flow symbols.

IntelliJ IDEA helps you create, edit, lint, run, debug, and maintain your React Native applications. Learn more from the React Native official website.

It is created by Facebook and used for such well-known apps as Instagram, Airbnb, and now JetBrains’ own YouTrack mobile application. With React Native you can develop native mobile applications for iOS and Android using JavaScript and React.
