Implement Firebase Push Notifications in React Native with Node.js Backend

This step-by-step guide includes Firebase Admin SDK setup, backend configuration, and sending targeted push notifications. You'll also learn how to configure your React Native Android project for Firebase integration.

📌 **Key Topics Covered:**
- Sending push notifications using FCM.
- Updating Android project files for Firebase integration.

📂 **Backend Code Examples:**

**Firebase Initialization:**
```javascript
const admin = require('firebase-admin');

// Load your Firebase service account key JSON file

});

```

**Send Notification Function:**
```javascript
const admin = require("./firebase");

async function sendNotificationToDevice(deviceToken, title, body) {
const message = {
notification: {
title: title,
body: body,
},
data: { name: "CODE_CATY" },
token: deviceToken, // FCM device token
};

try {
} catch (error) {
}
}

// Example usage
const deviceToken = "YOUR_DEVICE_FCM_TOKEN_HERE";
sendNotificationToDevice(
"Code Caty",
"This is a test notification."
);
```

📂 **Android Configuration:**

```gradle
// Add this line at the top of the file

dependencies {
// The version of react-native is set by the React Native Gradle Plugin

// Add these lines for Firebase dependencies

} else {
implementation jscFlavor
}
}
```

```gradle
dependencies {

// Add this line for Firebase services
}
```
