Error Tracking

Automatically capture JavaScript errors on your site.

How it works

Revlytics captures unhandled JavaScript errors via window.onerror and unhandledrejection events. Errors are sent as error event types.

Captured data

Field	Description
error_name	Error type (e.g., TypeError, ReferenceError)
error_message	Error message
error_stack	Stack trace (up to 2KB)
filename	Source file URL
lineno	Line number
colno	Column number

Deduplication

The same error (same message + filename) is deduplicated within a 1-minute window. This prevents error floods from crashing loops or rapidly-firing events.

Filtered errors

The following are automatically filtered out:

• ResizeObserver loop errors — Common, benign browser noise
• Third-party script errors — Errors from scripts on other domains (where filename doesn’t match your hostname)

No configuration needed

Error tracking is enabled by default. There is no attribute to disable it independently, but you can filter errors in the dashboard.
