Using Sentry For React Native Expo Applications

Using Sentry with React Native Expo applications involves a few steps. Here’s a guide to help you integrate Sentry into your Expo app:

1. Installation:

First, you’ll need to install the necessary packages:

expo install @sentry/react-native

2. Configuration:

After installation, you need to configure Sentry in your application.

In your main application file (e.g., App.js):

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

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN', // Replace with your Sentry DSN
  enableInExpoDevelopment: true, // This will enable Sentry even in Expo's development mode
  debug: true, // If you want Sentry to print debug information
});

Replace 'YOUR_SENTRY_DSN' with the DSN value you get from your Sentry project settings.

3. Catching and Reporting Errors:

With the above configuration, Sentry will automatically catch and report JavaScript exceptions. However, if you want to capture exceptions or messages manually, you can do so:

try {
  // Some code that might throw an exception
} catch (error) {
  Sentry.captureException(error);
}

// To capture a message:
Sentry.captureMessage('A custom message about an event');

4. Adding Context:

You can add additional context to your error reports, which can help in debugging:

Sentry.configureScope(scope => {
  scope.setExtra('extra_info', 'Some extra info');
  scope.setUser({
    id: '12345',
    username: 'test_user',
  });
});

5. Release and Source Maps:

You’ll need to configure releases and upload source maps to differentiate between errors from different versions of your app and get proper source maps for better error traces. This is more involved and might require additional configuration, especially using a managed Expo workflow.

Note:

If you’re using a managed Expo workflow, you might need to consider some limitations and additional steps, especially regarding native code and source maps. Refer to the official Sentry and Expo documentation for the most up-to-date and detailed instructions.

Remember to test the Sentry integration in a safe environment (like a staging version of your app) before deploying to production to ensure everything works as expected.
