feat(tracing): Add check and download timing spans to Expo Updates listener by antonis · Pull Request #6430 · getsentry/sentry-react-native

antonis · 2026-07-09T12:29:48Z

📢 Type of change

Bugfix
New feature
Enhancement
Refactoring

📜 Description

Adds timing spans to the expoUpdatesListenerIntegration to capture how long OTA update checks and downloads take. The integration previously only emitted breadcrumbs for state transitions — now it also creates spans:

app.update.check — measures the duration of an update check (from isChecking=true to completion or error)
app.update.download — measures the duration of an update download (from isDownloading=true to completion or error)

Both spans:

Use forceTransaction: true since OTA checks typically happen outside user-interaction transactions
Set expo.update.id attribute on success when a manifest ID is available
Set error status with the error message on failure
Are properly cancelled (with error status) on client close or re-init to prevent leaks

Existing breadcrumb behavior is fully preserved.

💡 Motivation and Context

The expoUpdatesListenerIntegration captures that a check/download happened but not how long it took. When investigating slow app starts or poor UX after an OTA update, there's no way to see whether the update check or download was the bottleneck.

Closes #6337

💚 How did you test it?

33 unit tests covering all span lifecycle paths (start, ok/error end, close cleanup, re-init cleanup, full lifecycle)
All existing breadcrumb tests continue to pass unchanged
All 272 integration tests pass
npx jest test/integrations/expoupdateslistener.test.ts — 33/33 pass

📝 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.
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

…stener The integration now creates spans (`app.update.check`, `app.update.download`) alongside the existing breadcrumbs, capturing how long OTA update checks and downloads take. Spans use `forceTransaction: true` since OTA checks typically happen outside user-interaction transactions. In-progress spans are properly cancelled on client close or re-init.
