Question 1

Sentry Capacitor vs Firebase Crashlytics for mobile apps?

Accepted Answer

Sentry Capacitor is tailored for Capacitor hybrid apps, offering detailed JavaScript and native error tracking with performance monitoring, while Firebase Crashlytics focuses more on native Android/iOS. Sentry provides richer context and breadcrumbs, but Firebase might be simpler if you're already using Google's ecosystem for other services.

Question 2

How to set up Sentry Capacitor with an Ionic Vue app?

Accepted Answer

Install @sentry/capacitor and @sentry/vue with exact versions using yarn or npm, then initialize Sentry early in your app's entry point. Follow the Sentry documentation for Capacitor and Vue specifics, ensuring you handle Ionic's build configuration to avoid conflicts.

Question 3

Does Sentry Capacitor work with Capacitor 5?

Accepted Answer

Yes, Sentry Capacitor is compatible with recent Capacitor versions, but always check the official documentation for the latest version requirements. Updates may introduce breaking changes, so test thoroughly with your specific Capacitor setup.

Question 4

How to capture custom errors manually in Sentry Capacitor?

Accepted Answer

Use the captureException or captureMessage APIs from @sentry/capacitor, passing error objects or custom strings. You can add context by setting extras, tags, or user info with scope methods like setExtra before capturing events.

Question 5

What's the performance impact of using Sentry Capacitor?

Accepted Answer

Sentry adds minimal overhead in production, but initialization and error capture can introduce slight latency. Mitigate this by disabling Sentry in development, using sampling to reduce data volume, or optimizing event breadcrumbs to avoid excessive logging.

Question 6

Can I use Sentry Capacitor for offline error logging?

Accepted Answer

Yes, Sentry Capacitor supports offline error queuing and will send captured events when connectivity is restored. Configure this through SDK options like enabling caching, but be aware of storage limits and potential data loss in extreme cases.
