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 🙏

Readme

@croco/telemetry-api

애플리케이션 코드에서 사용하는 OpenTelemetry 추적 API입니다. SDK 초기화는 @croco/telemetry-sdk-node가 담당하고, 이 패키지는 Span 생성과 이벤트 기록을 담당합니다.

설치

pnpm add @croco/telemetry-api @opentelemetry/api

사용법

@Trace 데코레이터

import { Trace } from "@croco/telemetry-api";

class OrderService {
  @Trace({ name: "order.create" })
  async createOrder(): Promise<void> {}
}

withSpan과 이벤트 기록

import { recordEvent, withSpan } from "@croco/telemetry-api";

await withSpan(async (span) => {
  span.setAttribute("feature", "checkout");
  recordEvent("checkout.started");
});

현재 Trace 정보 읽기

import { getActiveTraceInfo } from "@croco/telemetry-api";

const traceInfo = getActiveTraceInfo();

API 레퍼런스

  • Trace: 비동기 메서드를 Span으로 감싸는 데코레이터
  • withSpan: 수동 Span 실행 유틸리티
  • recordEvent: 현재 활성 Span에 이벤트 추가
  • recordError: 현재 활성 Span에 에러 기록
  • getActiveTraceInfo: 현재 traceId, spanId, traceFlags 조회
  • getTracer: 수동 Span 생성용 Tracer 반환
  • 타입: TraceDecoratorOptions, SpanOptions, TraceInfo, TracerOptions

참고

  • 이 패키지만 단독으로 사용하면 Span이 전송되지 않습니다.
  • 애플리케이션 시작 시 @croco/telemetry-sdk-node로 먼저 SDK를 초기화해야 합니다.
