Firebase crashlytics in ReactNative

Integrating crash reporting tools like Crashlytics in a React Native project at the component level involves a combination of native code and JavaScript. Below are the general steps for integrating Crashlytics in both Android and iOS platforms:

1. Install necessary packages:

For Crashlytics, you’ll need to install the react-native-firebase package. This package provides a convenient way to integrate Firebase services, including Crashlytics, into your React Native project.

npm install @react-native-firebase/app
npm install @react-native-firebase/crashlytics

2. Link the packages:

npx react-native link @react-native-firebase/app
npx react-native link @react-native-firebase/crashlytics

3. Configure Firebase:

Android:

  • Follow the instructions in the official documentation to add the necessary configurations to your android/app/build.gradle and android/build.gradle files.

iOS:

  • Follow the instructions in the official documentation to add the necessary configurations to your Xcode project.

4. Initialize Firebase:

In your main index.tsx or App.tsx file, initialize Firebase by adding the following code:

import { AppRegistry } from 'react-native';
import messaging from '@react-native-firebase/app';
import Crashlytics from '@react-native-firebase/crashlytics';
import App from './App';
import { name as appName } from './app.json';

// Initialize Firebase
if (!messaging.apps.length) {
messaging.initializeApp();
Crashlytics().setCrashlyticsCollectionEnabled(true);
}

AppRegistry.registerComponent(appName, () => App);

5. Use Crashlytics in Components:

Now, you can use Crashlytics in your React Native components to log custom events or catch errors:

import React, { useEffect } from 'react';
import { View, Button } from 'react-native';
import Crashlytics from '@react-native-firebase/crashlytics';

const MyComponent = () => {
useEffect(() => {
// Log a custom event
Crashlytics().log('MyComponent mounted');

// Log a custom error
try {
// Some code that might throw an error
} catch (error) {
Crashlytics().recordError(error.message);
}
}, []);

return (
<View>
{/* Your component UI */}
<Button title="Press me" onPress={() => {/* Your button press logic */}} />
</View>
);
};

export default MyComponent;

Remember to handle errors appropriately in your components and log them using Crashlytics to track and diagnose issues.

Note: Make sure you carefully follow the documentation for the specific versions of the packages you are using, as they may be subject to updates.
