Improvements

Enhanced Browser SDK capabilities for better trace correlation in Discover Applications

Improvements

  • Better trace correlation for custom events: Custom events created via L9RUM.addEvent() are now properly associated with the active view root span instead of creating independent traces, improving trace correlation and view-level analysis
  • Backend trace context propagation: Browser SDK now automatically injects W3C trace context headers into fetch and XHR requests, correlating frontend traces with backend services
  • Global span attributes: Applications can register custom attributes that are automatically included in every span for consistent metadata across traces
  • Unified error capture pipeline: New L9RUM.captureError() API enables manual error reporting, with configurable automatic capture from console errors, global error handlers, ReportingObserver, and network failures
  • Custom event tracking: L9RUM.addEvent() API now emits custom standalone traces enriched with session and view context, enabling tracking of user actions like button clicks
