Existing Apps

If you want to use parts of the Expo SDK in your existing React Native app, you are in the right place.

Most packages in the Expo SDK depend on a module tooling installed with the expo package. Once it is installed and configured in your app, you can install other packages from the Expo SDK just as you would any other React Native library.

Setting up the `expo` package

Follow the the installing Expo modules guide. It should take about five minutes to configure in an existing app.

Install libraries from the Expo SDK

The short version: find an Expo package that you would like to use in the API reference or by searching this documentation, eg: expo-web-browser, install it with npm, then run npx pod-install and re-build your app.

The longer, more detailed version: check out Install an Expo SDK package in the "Up and Running" guide.

That's it!

You're ready to go. You may also want to install expo-updates in your project to add support for updates. If so, follow the installing expo-updates guide guide once you have installed expo.
