Overview


Expo is an open-source framework for apps that run natively on Android, iOS, and the web. Expo brings together the best of mobile and the web and enables many important features for building and scaling an app.

  • Develop: Developing an app requires writing code in JavaScript/TypeScript. When you create a new project, Expo provides a standard project structure which you can customize as per your needs. It also provides development builds that help your team to iterate quickly to achieve web-like iteration speeds and safely.

There are plenty of other features and best practices to continue exploring along the way, such as collaborating with your team, using Expo modules, debugging, and working on the command line with Expo CLI.
