/*!
|
||||
* otel-rum.js - browser error/RUM collector for go-otel.
|
||||
*
|
||||
* Captures uncaught errors, unhandled promise rejections, failed resource
|
||||
* loads, failing HTTP requests and Web Vitals (LCP/INP/CLS/TTFB/FCP), and
|
||||
* ships errors as OTLP log records to this server's existing /v1/logs endpoint
|
||||
* (no separate ingestion path needed - the backend's issue view picks these
|
||||
* up like any other error log). Web Vitals go out separately: one beacon per
|
||||
* page view to /v1/vitals, measured with the vendored web-vitals library.
|
||||
*
|
||||
* Also exposes a `traceHeaders()` helper so outgoing `fetch`/XHR calls can
|
||||
* carry a W3C `traceparent` header. If the backend service is itself
|
||||
* OTel-instrumented and honors incoming trace context (most server
|
||||
* instrumentation does by default), spans it creates for that request will
|
||||
* share the same trace id - so a frontend error and the backend spans it
|
||||
* triggered can be found together via GET /api/traces/{traceId}.
|
||||
*
|
||||
* Usage:
|
||||
* <script src="https://otel.k6n.net/static/otel-rum.js"></script>
|
||||
* <script>
|
||||
* var rum = OtelRUM.init({
|
||||
* serviceName: 'my-web-app',
|
||||
* baseUrl: 'https://otel.example.com', // optional collector override
|
||||
* });
|
||||
*
|
||||
* // Manual correlation-id injection into any HTTP client:
|
||||
* fetch('/api/orders', { headers: rum.traceHeaders() });
|
||||
*
|
||||
* // Manual error reporting:
|
||||
* try { risky(); } catch (err) { rum.captureException(err); }
|
||||
* </script>
|
||||
*
|
||||
* Events are batched client-side (flushed on pagehide via keepalive fetch/sendBeacon) and
|
||||
* rate-limited, so a runaway error loop cannot hammer the collector.
|
||||
*
|
||||
* Source-map resolution is performed server-side by go-otel when a matching
|
||||
* release map has been uploaded. Session replay and PII scrubbing remain out
|
||||
* of scope; don't route sensitive data through breadcrumbs/attributes.
