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 🙏

소개

구글 GeoLocation API와 KMA의 날씨 정보(RSS)를 이용하여 날씨 정보를 받아오는 라이브러리 입니다.

KMA에서 날씨정보를 얻어오기 위해서는 bcode (지역코드)가 필요하지만 해당 라이브러리를 이용하면 좌표를 이용해서 해당 지역의 날씨 정보를 받아 올 수 있습니다.

해당 라이브러리의 작동 방식은 다음과 같습니다.

  1. 유저가 좌표를 이용해서 날씨 정보를 요청.
  2. Google Maps GeoLocation API 를 이용하여 좌표를 주소로 변환.
  3. KMA에 있는 bcode <-> 좌표 매치 데이터를 이용하여 bcode 를 얻어옴.
  4. bcode를 이용하여 KMA에 현재 날씨 정보를 받아옴.

해당 라이브러리를 사용한 예시 페이지

라이브러리 사용 조건

  • ES6
  • Promise
  • Node.js

빠른 시작

설치 방법

npm install kma-js
