metricskit — orvacon

@orvacon/metricskit is a plugin that increments a counter on every payment lifecycle event, tagged with the currency and connector — so you get success / failure / refund rates and volume by gateway in your existing dashboards.

bun add @orvacon/metricskit

import { orvacon } from "@orvacon/paykit";
import { metricskit } from "@orvacon/metricskit";

orvacon({
  // … database, connectors, webhookSigningKey
  plugins: [metricskit({ sink: { inc: (name, tags) => prometheus.inc(name, tags) } })],
});
// → orvacon.payment.captured{currency="TRY",connector="iyzico"}

The sink is a single inc(name, tags?) — wrap Prometheus, StatsD, OpenTelemetry, or your own counter. It counts authorized, captured, refunded, failed, and voided; prefix renames the namespace (default "orvacon").

Counts only — derive revenue from your own payment records. metricskit reacts through hooks, so a slow or throwing sink is reported through onError and never blocks the payment.
