This will make a project structure with an index file named App.js in your project directory. Try uninstalling the cli and run the cli using npx. Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. If you want to start a new project with a specific React Native version, you can use the -version argument: npx react-native init ProjectName -version X.XX.X If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues: npm uninstall -g react-native-cli the following commands to create a new React Native project npx react-native init ProjectName We are going to use react native command line interface to make our React Native App. Getting started with React Native will help you to know more about the way you can make a React Native project.

JSON stream supported base on Oboe.js Download an Image.Blob, File, XMLHttpRequest polyfills that make the browser-based library available in RN (experimental).File stream support for dealing with large file.Native-to-native file manipulation API, reduce JS bridging performance loss.

File API supports regular files, Asset files, and CameraRoll files.
