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.

1. Google Maps Integration
2. React Native Firebase Integration
3. Enabling usesClearTextTraffic (Android)

Setup

To use these plugins in your Expo project, follow the steps below:

$3

You need to install Expo config plugins to utilize the custom plugins.

``bash
npm install expo-config-plugins
`

$3

In your project's app.json or app.config.js, add the respective plugin configurations:

#### Google Maps Plugin

`json
{
"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

`json
{
"expo": {
"plugins": [
"expo-config-plugins/lib/with-react-native-firebase"
]
}
}
`

#### Android Cleartext Traffic Permission Plugin

`json
{
"expo": {
"plugins": [
"expo-config-plugins/lib/with-uses-cleartext-traffic"
]
}
}
`

This will allow Android apps to use cleartext network traffic.

$3

Once the plugins are added to your configuration, Expo will automatically apply the necessary changes to the native project files during the build process.

$3

After setting up the configuration, run the following command to build your app:

`bash
eas build -p android|ios
`

This will generate and modify the native files required for the integrations to work.

Plugin Details

$3

- iOS: Adds Google Maps dependencies to the Podfile and updates AppDelegate.mm to configure the API key.
- Android: Adds the Google Maps API key to the AndroidManifest.xml.

$3

- 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: Enables cleartext traffic by setting android:usesCleartextTraffic to true in the AndroidManifest.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.
