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 🙏

LS 투자증권 OPEN API Library

Readme

LS증권 (구 이베스트 투자증권) OPEN API Library

LS증권 Open API(RESTful) 사용을 간단히 하기 위한 node.js 모듈입니다


1. 초기화

const ebest=require('k-ebest-im')({AppKey},{AppSecretKey},{모의투자여부},{실시간사용여부});  

AppKey - LS증권 open api 발급 키
AppSecretKey - LS증권 open api 발급 비밀 키
모의투자여부 - [(false)/true] true일때 웹소켓 주소 모의투자 서버로 사용
실시간사용여부 - [false/(true)] 웹소켓 연결을 사용할지 여부(실시간 사용시 true)

2. tr 요청

const tr = await ebest.주식.시세.주식분별주가조회('005930','1','',10);  
if(tr!==null){//null이면 실패  
    for(var obj of tr.t1302OutBlock1){//배열 데이터  
        console.log(obj.close);//종가  
    }  
}  

3. 실시간 요청

const sub=await ebest.주식.실시간.KOSPI체결.등록('005930',(data)=>{  
    //등록 후 체결이 있을경우 함수 실행  
    console.log(obj.price);//현재가  
});  
console.log(sub);//실시간 등록 성공 여부  
const unsub=await ebest.주식.실시간.KOSPI체결.해제('005930');  
console.log(unsub);//실시간 해제 성공 여부  

실시간 해제시에는 등록했을때의 동일 키 사용 필수

4. 연속 tr 요청

//요청한 tr이 완료된 후 (global) __tr_cont, __tr_cont_key 로 다음 연속 조회가 가능합니다
var tr = await ebest.주식.시세.주식분별주가조회(...);
while(global.__tr_cont==='Y'){
    tr = await ebest.주식.시세.주식분별주가조회(..., global.__tr_cont, global.__tr_cont_key);  
}
