It exists for teams that want useful service telemetry without wiring every observability concern by hand on day one. Corelens is not a full OpenTelemetry replacement. It is a practical SDK that covers common application instrumentation paths and can export to places that already speak OTLP. What It Solves - Structured logs with optional trace correlation. - Application metrics with counters, gauges, and histograms. - HTTP request metrics and tracing for supported frameworks. - Runtime metrics for Node.js process health. - Local Prometheus text rendering for scrape-based metrics. - Console, file, and OTLP-HTTP export for logs, metrics, and traces. - Bounded queues, retry, circuit breaker, and shutdown behavior for production export paths. - A small debug/stats surface for understanding dropped items, exporter failures, and queue state. Install Install your framework only if you use its adapter: Express, Fastify, and Hono are optional peer dependencies. Corelens itself can be used without any framework adapter. Quickstart Supported Signals Logs Corelens logs are structured events written through lens.logger . Log configuration: Metrics Metrics are recorded in a local registry and can be rendered as Prometheus text or exported through the export pipeline.
