Crash Reporting

Crash reporting tools automatically capture and report application crashes occurring on real user devices, providing essential visibility into stability issues that would otherwise go unnoticed.

Why Crash Reporting Matters

Without crash reporting, developers only learn about crashes through user complaints or app store reviews, often missing the specific context needed to diagnose and fix the underlying issue.

Installing Firebase Crashlytics

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

Logging a Custom Non-Fatal Error

javascript import crashlytics from '@react-native-firebase/crashlytics'; try { await processPayment(); } catch (error) { crashlytics().recordError(error); }

Adding User Context

javascript crashlytics().setUserId(user.id); crashlytics().setAttribute('subscriptionTier', user.tier);

Adding Breadcrumb Logs

javascript crashlytics().log('User navigated to checkout screen');

Using Sentry as an Alternative

Sentry offers similar crash reporting capabilities, along with additional performance monitoring features, providing detailed stack traces and release tracking for React Native applications.

Testing Crash Reporting Integration

javascript crashlytics().crash(); // Forces a test crash to verify integration

Setting Up Alerts

Configure alerts for crash rate spikes so your team is notified immediately when a new release introduces a significant stability regression, allowing for rapid response.

Conclusion

Implementing crash reporting using tools like Firebase Crashlytics or Sentry provides essential visibility into production stability, allowing teams to identify and fix critical issues before they affect a large portion of users.
