Expo is an open-source framework and platform built around React Native, designed to streamline the development process for cross-platform mobile applications. It provides a managed workflow that includes a comprehensive set of tools, APIs, and services for building, testing, and deploying apps for iOS, Android, and web—all using JavaScript or TypeScript.
Expo simplifies mobile development by handling much of the native configuration behind the scenes. Developers can use the Expo Go app to preview and test their projects instantly on real devices, while the Expo CLI offers powerful commands for creating, running, and managing apps. The Expo SDK provides prebuilt modules for features like camera access, push notifications, geolocation, and more, allowing you to focus on app logic rather than native integrations. For production workflows, EAS (Expo Application Services) supports custom builds, over-the-air updates, and app store submissions.
