Questions tagged [create-react-app]

create-react-app is a starter-kit for creating React applications with no build configuration. If you’re getting started with React, use this to automate the build of your application. There isn't any configuration file, and react-scripts is the only extra build dependency in your package.json file. Your environment will have everything you need to build a modern React application.
