Properties

Optional allowlist

allowlist?: string | RegExp | ((urlOrPath) => boolean) | (string | RegExp | ((urlOrPath) => boolean))[]

List of URLs/paths that should be instrumented.

Note that when used for an http client the entry represents a full outbound URL (https://example.org/api/foo) but when used as a server the entry represents an inbound path (/api/foo).

Optional blocklist

blocklist?: string | RegExp | ((urlOrPath) => boolean) | (string | RegExp | ((urlOrPath) => boolean))[]

List of URLs/paths that should not be instrumented. Takes precedence over allowlist if a URL matches an entry in both.

Note that when used for an http client the entry represents a full outbound URL (https://example.org/api/foo) but when used as a server the entry represents an inbound path (/api/foo).
