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

화면에 보이는 요소만 렌더링함으로써 성능 개선에 도움을 줄 수 있는 리액트 컴포넌트입니다.

다음과 같이 react-window를 사용하면서 느낀 불편한 점들을 개선하였습니다.

  • 내부 스크롤이 생기지 않는 방식으로 구현하였습니다. react-window는 List 내부에 스크롤이 생겨 이 스크롤 위치를 감지하나, 본 컴포넌트에서는 스크롤 타겟 요소를 지정해줄 수 있습니다.
  • List 내부의 Item 컴포넌트에 props를 넘겨줄 수 있습니다.

사용법

<FixedSizeList scrollTarget={window} top={0} itemHeight={300} itemData={data} overscanCount={2}>
  <Item newprops={newprops} />
</FixedSizeList>
  • scrollTarget: 스크롤 타겟 요소
  • top: 스크롤 타겟 요소 내에서 List의 y축 위치
  • itemHeight: 아이템의 높이
  • itemData: 렌더링 시 사용할 배열 형태의 데이터
  • overscanCount: 위 아래로 추가로 렌더링할 요소의 개수
