Function createLogger

Parameters

• OptionalserviceName: string

  Optional service name included in log output. When omitted the OTLP exporter's resource attributes (e.g. service.name) are used instead — this is the recommended approach so that the service name is configured in a single place.

  Dual output:

  1. Stderr — pino (Node + pino installed), built-in formatter (Node without pino), or console[level] (Cloudflare Workers).
  2. OTLP — emits via the global LoggerProvider if one is registered.

  Every method is wrapped in try-catch — never throws.
