feat(core): Expose native breadcrumb off-switches by antonis · Pull Request #6768 · getsentry/sentry-react-native

antonis · 2026-09-23T07:58:39Z

📢 Type of change

Bugfix
New feature
Enhancement
Refactoring

📜 Description

Exposes native breadcrumb off-switches so apps can disable native breadcrumbs that largely duplicate the ones the JS SDK already records:

enableAutoBreadcrumbTracking (iOS) — read by sentry-cocoa's options dictionary parser, so it needs only the JS type + JSDoc.
enableActivityLifecycleBreadcrumbs, enableAppLifecycleBreadcrumbs, enableSystemEventBreadcrumbs, enableAppComponentBreadcrumbs (Android) — each mapped explicitly in RNSentryStart.java to its SentryAndroidOptions setter.

All default to true (matching the native defaults); the JS wrapper forwards them to native automatically (only functions/JS-only keys are filtered out). Follows the same mechanism as #6764.

💡 Motivation and Context

Part of #6747

💚 How did you test it?

Added tests: JS forwarding (wrapper.test.ts) and Android option mapping (RNSentryStartTest.java, covering true/false forwarding and native-default preservation when unset).
Manually

📝 Checklist

I added tests to verify changes.
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
I updated the docs if needed feat(react-native): Document native breadcrumb off-switches sentry-docs#19576
I updated the wizard if needed.
All tests passing.
Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.
No breaking changes.

🔮 Next steps

Expose enableAutoBreadcrumbTracking (iOS) and enableActivityLifecycleBreadcrumbs, enableAppLifecycleBreadcrumbs, enableSystemEventBreadcrumbs, enableAppComponentBreadcrumbs (Android) so apps can turn off the native breadcrumbs, which largely duplicate the JS breadcrumbs. All default to the native default (true). iOS is read by cocoa's dictionary parser; Android is mapped in RNSentryStart. Part of #6747. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
