Functions

navigationObserver

function navigationObserver(tracer?: Tracer): (event: NavigationEvent) => void

The observe function for createRouter: a span named navigate opens when a navigation starts and ends when it commits, fails, or is canceled by a newer navigation, with zerolith.route, url.path, url.query when the URL has a query, and zerolith.navigation.mode as attributes, the loader's error recorded on failure, and zerolith.navigation.canceled set on a canceled one, whose status stays unset. The values of the query keys the URL conventions redact, such as sig, are recorded as REDACTED.

traceparent

function traceparent(active?: Context): string | undefined

The W3C traceparent header for a context, or undefined when no span is active in it.

Source: packages/otel/src/index.ts:107

tracedTransport

function tracedTransport(transport: Transport | undefined, tracer?: Tracer): Transport

Wraps a transport, or fetch when none is given, so every request runs in a client span named by its method, as GET, with http.request.method, url.full, and http.response.status_code, carries a traceparent header from that span, and records a failed request as an error. The span is not named by the request's path, which would give every note its own span name; the HTTP conventions name a client span by its method when no route template is known. url.full records the values of the query keys the conventions redact, such as sig, as REDACTED.
