@sentry/react-native

What is @sentry/react-native?

@sentry/react-native is a comprehensive error tracking and performance monitoring tool for React Native applications. It helps developers capture and report errors, monitor application performance, and gain insights into issues affecting their apps.

What are @sentry/react-native's main functionalities?

Error Tracking

This feature allows you to capture and report errors in your React Native application. The code sample initializes Sentry with a DSN and captures an exception.

import * as Sentry from '@sentry/react-native';

Sentry.init({
  dsn: 'https://[e-mail]/0',
});

try {
  throw new Error('Test error');
} catch (error) {
  Sentry.captureException(error);
}

Performance Monitoring

This feature allows you to monitor the performance of your application. The code sample initializes Sentry with a DSN and a traces sample rate, then starts and finishes a transaction.

import * as Sentry from '@sentry/react-native';

Sentry.init({
  dsn: 'https://[e-mail]/0',
  tracesSampleRate: 1.0,
});

const transaction = Sentry.startTransaction({
  name: 'test-transaction',
});

setTimeout(() => {
  transaction.finish();
}, 2000);

Breadcrumbs

Breadcrumbs are used to record events that lead up to an error. The code sample initializes Sentry and adds a breadcrumb for a user login event.

import * as Sentry from '@sentry/react-native';

Sentry.init({
  dsn: 'https://[e-mail]/0',
});

Sentry.addBreadcrumb({
  category: 'auth',
  message: 'User logged in',
  level: Sentry.Severity.Info,
});

User Feedback

This feature allows users to provide feedback when an error occurs. The code sample initializes Sentry and shows a report dialog for user feedback.

import * as Sentry from '@sentry/react-native';

Sentry.init({
  dsn: 'https://[e-mail]/0',
});

Sentry.showReportDialog({
  title: 'Feedback',
  subtitle: 'Please describe what you were doing when the error occurred.',
  labelName: 'Name',
  labelEmail: 'Email',
  labelComments: 'Comments',
  labelSubmit: 'Submit',
  successMessage: 'Thank you for your feedback!',
});
