Expo Config Plugins
This project provides a collection of custom Expo config plugins to integrate Google Maps, React Native Firebase, and additional Android permissions (such as usesClearTextTraffic
) into an Expo-managed project.
Overview
Expo Config Plugins enable you to customize and extend the native behavior of an Expo project without ejecting. These plugins automatically modify native files during the build process, allowing you to integrate native modules that require additional configurations.
Included Plugins
- Google Maps Integration
- React Native Firebase Integration
- Enabling usesClearTextTraffic (Android)
Setup
To use these plugins in your Expo project, follow the steps below:
1. Install the Required Packages
You need to install Expo config plugins to utilize the custom plugins.
npm install expo-config-plugins
2. Add the Plugins to app.json
or app.config.js
In your project's app.json
or app.config.js
, add the respective plugin configurations:
Google Maps Plugin
{
"expo": {
"plugins": [
[
"expo-config-plugins/lib/with-google-maps",
{
"apiKey": "YOUR_GOOGLE_MAPS_API_KEY"
}
]
]
}
}
Replace YOUR_GOOGLE_MAPS_API_KEY
with your actual Google Maps API key.
React Native Firebase Plugin
{
"expo": {
"plugins": [
"expo-config-plugins/lib/with-react-native-firebase"
]
}
}
Android Cleartext Traffic Permission Plugin
{
"expo": {
"plugins": [
"expo-config-plugins/lib/with-uses-cleartext-traffic"
]
}
}
This will allow Android apps to use cleartext network traffic.
3. Usage
Once the plugins are added to your configuration, Expo will automatically apply the necessary changes to the native project files during the build process.
4. Building the App
After setting up the configuration, run the following command to build your app:
eas build -p android|ios
This will generate and modify the native files required for the integrations to work.
Plugin Details
1. Google Maps Integration (with-google-maps
)
- iOS: Adds Google Maps dependencies to the
Podfile
and updatesAppDelegate.mm
to configure the API key. - Android: Adds the Google Maps API key to the
AndroidManifest.xml
.
2. React Native Firebase Integration (with-react-native-firebase
)
- iOS: Configures Firebase to be used as a static framework and modifies
AppDelegate.mm
to initialize Firebase.
Note: The Android configuration for Firebase has been commented out in the code. You can enable it by uncommenting the relevant parts in
src/with-react-native-firebase.ts
if needed.
3. Android Cleartext Traffic (with-uses-cleartext-traffic
)
- Android: Enables cleartext traffic by setting
android:usesCleartextTraffic
totrue
in theAndroidManifest.xml
.
Customization
You can modify these plugins to fit your own project needs. Each plugin is located in the src
directory:
- Google Maps:
src/with-google-maps.ts
- React Native Firebase:
src/with-react-native-firebase.ts
- Cleartext Traffic:
src/with-uses-cleartext-traffic.ts
If you need to further customize the way the plugins modify native files, you can adjust the mergeContentsAndSaveAsync
utility and the plugin logic directly.
