Instrument Node.js APIs.

Adapters automatically retain normalized route templates, response status, duration, API version and explicit customer context.

@apirelio/core owns event creation, route normalization, bounded metadata, retry, backpressure and graceful shutdown.

npm install @apirelio/core

import { ApirelioClient } from '@apirelio/core'

const apirelio = new ApirelioClient({
  apiKey: process.env.APIRELIO_API_KEY!,
  service: 'billing-api',
  environment: 'production',
})

apirelio.capture({
  method: 'POST',
  route: '/api/invoices/:invoice/send',
  status: 202,
  durationMs: 84,
  customer: { id: 'cus_123', plan: 'growth' },
  sdk: 'custom',
  sdkVersion: '0.2.0',
})

Capture only enqueues an in-memory event. Batches are delivered in the background with timeouts and bounded retry; a full queue drops telemetry instead of slowing or breaking the customer API.
