requestIdOf(
request,headerName?):string|undefined
Defined in: src/http/middleware/RequestId.ts:32
The request id request carries, or undefined when it carries none —
or when what it carries is not a well-formed id.
The check is the reason this is a function rather than a header read at the call site: the value is client-controlled, and raw client bytes on a log line can forge whole log records through an embedded newline. It is the same check the middleware applies before echoing an incoming id into a response header, deliberately shared rather than re-derived.
What comes back is what the request claimed, which is what correlation
needs — with trustIncoming: false the middleware will have generated a
different id for everything downstream of it, so a caller that logs this
should name the header it came from rather than present it as the id.
