Support for Expo's Config Plugins was added in version 2.0. You can find the full documentation here: https://docs.expo.dev/config-plugins/introduction/

In order to use a config plugin in react-native-test-app, there are two things you need to do:

1. Add @expo/config-plugins as a dev dependency:
   • Yarn: yarn add @expo/config-plugins --dev
   • npm: npm add @expo/config-plugins --save-dev
2. Add the config plugins you want to use in your app.json under plugins. In the example below, we're adding the config plugin for Reanimated that comes bundled react-native-test-app:

    "presentationStyle": "modal" } ], + "plugins": [ + "react-native-test-app/plugins/reanimated.js" + ], "resources": { "android": [ "dist/res",

The following plugins are included in the package:

• react-native-test-app/plugins/reanimated.js — Installs the runtime required by React Native Reanimated

As of writing, most of the mods that come with @expo/config-plugins work out-of-box, with the sole exception being the Expo specific mods.ios.expoPlist. Additionally, the following react-native-test-app specific mods have been defined:

• mods.ios.bridgeDelegate — Modify ios/ReactTestApp/BridgeDelegate.mm as a string (dangerous)
• mods.ios.sceneDelegate — Modify ios/ReactTestApp/SceneDelegate.swift as a string (dangerous)

As of 3.9.0, config plugins should also work on macOS. Instead of importing mods from @expo/config-plugins, import them from react-native-test-app/plugins/macos. See plugins/macos.js for currently available mods.
