Set up a modern web app by running one command.
Create React App is a zero-configuration build tool for setting up modern React web applications with a single command. The project is built around a monorepo structure that includes several npm packages: the main create-react-app CLI tool, official templates for JavaScript and TypeScript, a Babel preset (babel-preset-react-app), an ESLint configuration (eslint-config-react-app), development utilities (react-dev-utils), browser polyfills (react-app-polyfill), and supplementary packages like confusing-browser-globals for static analysis. The tech stack centers on React, Webpack, Babel, and ESLint, with support for both JavaScript and TypeScript projects, and includes accessibility checks via eslint-plugin-jsx-a11y. The project is maintained by Facebook (now Meta), as evidenced by references to the facebook GitHub organization throughout the documentation.
