Month: 2025-10 — Delivered critical observability enhancements and stabilized core OpenTelemetry integration in honeycomb-opentelemetry-web. Key feature: CDN wrapper now exposes session management and OpenTelemetry APIs, enabling access to session IDs and instrumentation for custom code, with automatic session rotation and groundwork for metric exporters in the 1.1.0 release. Major bug fix: Removed redundant setGlobalTracerProvider call in WebSDK, eliminating console errors from duplicate tracer provider initialization. Release activity includes publishing honeycomb-opentelemetry-web v1.1.0 with updated examples and session-tracking capabilities. Impact: significantly improved developer experience for instrumenting CDN-based workloads, stronger observability, and a stable foundation for future metrics export. Skills demonstrated: OpenTelemetry integration, session management design, API exposure, release management/versioning, and code cleanup for stability.
