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 🙏

注意事项

  1. 确保传入的 data 数组不为空
  2. 自定义 itemHeight 或 itemWidth 时,请确保与实际样式一致
  3. 使用 loop 模式时,列表数据会自动复制一份以实现无缝滚动
  4. 滚动速度建议设置为 0.5-2 之间,过大可能导致滚动过快
  5. 在组件销毁时会自动停止滚动,无需手动清理
  6. 拖拽功能支持鼠标和触摸事件,拖拽时会自动暂停自动滚动
  7. 拖拽结束后,如果之前不是暂停状态,会自动恢复滚动
  8. 拖拽范围受容器大小限制,超出边界会自动停止
