Imported Packages allow you to add third-party libraries to your app.


React Native & Expo

Imported libraries must be compatible with React Native and the Expo managed workflow



Packages which require running pod install for iOS installation are not currently supported. Look for packages without this requirement



Packages which require linking are not currently supported. Look for packages which have auto-linking

Finding compatible packages

You can find several compatible libraries here. Make sure they also meet the above requirements.

If you want to import libraries from the npm registry, please follow Expo's tips for determining compatibility.

Adding a package

First, navigate to the Packages tab in the Custom Code modal.

Click the "+" icon to add a new package.

Then, enter your Package Name in the first input field and it's Version in the second input field.


In most cases, you will want the latest version of your package.

If you want a specific version, be sure to specify in the version input, with or without npm ~, ^, or >= syntax.


To remove a package, click the '-' button at the end of the row where the package is listed.
