Intro to create-react-app

Create React App is an officially supported way to create single-page React applications. It offers a modern build setup with no configuration.

Quick Start

npx create-react-app my-app
cd my-app
npm start

❗️NOTE: npx on the first line is not a typo — it’s a package runner tool that comes with npm 5.2+. If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version.

• Create React App doesn’t handle backend logic or databases; it just creates a frontend build pipeline, so you can use it with any backend you want. Under the hood, it uses Babel and webpack, but you don’t need to know anything about them.

JavaScript build toolchain

• Yarn & npm: They are the Package manager. It lets you take advantage of a vast ecosystem of third-party packages, and easily install or update them.
• webpack & Parcel: They are the bundler. It lets you write modular code and bundle it together into small packages to optimize load time.
• Babel: A compiler. Babel is a free and open-source JavaScript transcompiler that is mainly used to convert ECMAScript 2015+ code into a backwards compatible version of JavaScript that can be run by older JavaScript engines.
