The official Prometheus client library for Node.js, supporting counters, gauges, histograms, and summaries. It exposes metrics via a registry that can be scraped by Prometheus, and includes default Node.js runtime metrics like event loop lag and GC.

Use cases

• instrument a node.js app with prometheus metrics
• collect default node.js runtime metrics like event loop lag and gc
• expose a /metrics endpoint for prometheus scraping
• create custom counters, gauges, histograms and summaries
• monitor http request latency with histograms
• push metrics to a prometheus pushgateway

When to choose

• you run node.js services monitored by prometheus
• you need standard prometheus metric types in javascript
• you want built-in node.js runtime metrics out of the box

When to avoid

• you need metrics for a non-node.js runtime
• you want a full metrics dashboarding solution rather than a client library
• you use a different monitoring ecosystem like statsd or opentelemetry exclusively
