# Deprecation of Coralogix Node.js Bunyan integration

**Published**: April 17, 2026

**Effective**: June 30, 2026

## Deprecation notice

Coralogix will deprecate the [Coralogix Bunyan integration](https://coralogix.com/docs/integrations/sdks/nodejs-bunyan/index.md) (`coralogix-logger-bunyan` npm package and Coralogix Bunyan stream) on June 30, 2026.

This integration is deprecated in favor of [OpenTelemetry for JavaScript](https://opentelemetry.io/docs/languages/js/) with Bunyan instrumentation, which is the recommended and supported approach for exporting Bunyan 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

The following Coralogix-maintained package and patterns are deprecated:

- `coralogix-logger-bunyan` and Coralogix-specific Bunyan streams that send logs directly to Coralogix

After the effective date, this package will no longer be supported or maintained.

## What you need to do

### Migrate to OpenTelemetry with Bunyan

Replace the Coralogix Bunyan stream with the [OpenTelemetry SDK for JavaScript](https://opentelemetry.io/docs/languages/js/) and [`@opentelemetry/instrumentation-bunyan`](https://www.npmjs.com/package/@opentelemetry/instrumentation-bunyan), exporting via OTLP. Follow the updated [Node.js Bunyan integration](https://coralogix.com/docs/integrations/sdks/nodejs-bunyan/index.md) documentation.

## What will happen after June 30, 2026?

- The Coralogix Bunyan logger package will no longer be supported.
- No bug fixes, updates, or security patches will be provided.
- Support requests related to the deprecated integration may be declined.
