Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Node.js와 AWS Lambda에서 OpenTelemetry SDK를 초기화하는 런타임 패키지입니다. OTLP exporter, 샘플링, 자동 계측, flush 제어를 제공합니다.

설치

pnpm add @croco/telemetry-sdk-node

사용법

기본 초기화

import { TelemetryRuntime } from "@croco/telemetry-sdk-node";

const telemetry = TelemetryRuntime.getInstance();
await telemetry.init({
  serviceName: "orders",
  trace: {
    enabled: true,
    exporterUrl: "http://localhost:4318/v1/traces",
  },
});

Lambda 프리셋

import { TelemetryRuntime, lambdaPreset } from "@croco/telemetry-sdk-node";

const telemetry = TelemetryRuntime.getInstance();
await telemetry.init(
  lambdaPreset({
    serviceName: "orders",
    probability: 0.1,
  }),
);

종료 전 flush

const result = await telemetry.forceFlush(5000);
if (!result.success) {
  throw result.error ?? new Error("telemetry flush failed");
}

API 레퍼런스

  • TelemetryRuntime: init, forceFlush, shutdown, isInitialized, getConfig
  • lambdaPreset: Lambda 환경 기본 설정 생성
  • ProbabilitySampler: 확률 기반 샘플링 구현체
  • 자동 계측: normalizeAutoInstrumentationConfig, LAMBDA_DEFAULT_MODULES, NODE_DEFAULT_MODULES
  • Problem: OtlpEndpointRequiredProblem, SamplerProblem
  • 타입: TelemetryConfig, TraceConfig, MetricsConfig, LogsConfig, ForceFlushResult
  • 메트릭 타입: MetricsApi, Counter, Histogram, Gauge
  • 로그 타입: LogsApi, Logger, LogRecord, LogSeverity

Lambda 참고

  • AWS_LAMBDA_EXEC_WRAPPER 방식은 사용하지 않습니다.
  • 핸들러 바깥에서 init()을 호출합니다.
  • 핸들러 종료 전에 forceFlush()를 호출합니다.
