Deprecation of Coralogix Node.js Winston integration
Published: April 17, 2026
Effective: June 30, 2026
Deprecation notice
Coralogix will deprecate the legacy Node.js Winston integration that shipped logs directly to the Coralogix Logs API (for example via Winston HTTP transport to the singles endpoint) on June 30, 2026.
That pattern is deprecated in favor of OpenTelemetry for JavaScript with Winston instrumentation, which is the recommended and supported approach for exporting Winston logs to Coralogix.
Action is required to ensure continued support and compatibility.
Why this is happening
The observability ecosystem has converged on OpenTelemetry as the industry standard for telemetry collection. Standardizing on OpenTelemetry reduces duplication and provides a consistent, long-term approach across languages and platforms.
What’s affected
Custom Winston transports or HTTP clients that post logs directly to Coralogix ingestion URLs without OTLP, as described in earlier documentation, are deprecated.
After the effective date, Coralogix will not support maintaining those client-side patterns as the primary integration path.
What you need to do
Migrate to OpenTelemetry with Winston
Replace direct API shipment with the OpenTelemetry SDK for JavaScript and @opentelemetry/instrumentation-winston, exporting via OTLP. Follow the updated Node.js Winston integration documentation.
What will happen after June 30, 2026?
- The legacy Winston-to-Coralogix Logs API approach will no longer be documented or supported as the recommended integration.
- Support requests may be directed toward OpenTelemetry-based setups.
