@elastic/ecs-winston-format

This Node.js package provides a formatter for the winston logger compatible with Elastic Common Schema (ECS) logging. In combination with the filebeat shipper, you can send your logs directly to Elasticsearch and leverage Kibana's Logs app to inspect all logs in one single place.

winston 3.x versions are supported.

Please see the Node.js ECS winston documentation.
