The expo command-line interface (CLI) is the entry point for Expo, an open-source platform for building cross-platform apps with JavaScript and React for Android, iOS, and web.

Key features include project initialization, development server startup with hot reloading, dependency management via expo install, custom builds with expo build, over-the-air updates via expo publish, and ejection to bare React Native workflow.

Expo simplifies native development by providing managed workflows, pre-built modules, and cloud services, reducing boilerplate code. It's ideal for rapid prototyping but supports production apps.

Note: Original expo-cli deprecated in 2021; use npx expo or npm install -g @expo/cli for latest.

Requires Node.js ≥14 and npm. Original expo-cli deprecated; prefer npx expo or @expo/cli. Not a core Linux utility.
