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 🙏

vue-list-autoscroll

这是一个vue指令,可以支持菜单横向滚动,当鼠标置于滚动容器的边界时,会触发滚动。当然该指令也不局限于菜单场景,其他的DOM元素也可以使用,使用时需要注意以下几点:

  1. 使用该指令时,建议使用这样的三层结构:div(滚动容器) > ul(横向列表) > li(列表元素)
<div class="scroll__wrapper">
  <ul class="scroll__list">
    <li class="scroll__item"></li>
    <li class="scroll__item"></li>
  </ul>
</div>
  1. div(滚动容器)应该是有确定的宽度,比如500px;必须指定overflow: hidden;
  2. ul(横向列表)应该设置样式
display: inline-block;
white-space: nowrap;
  1. li(列表元素)应该设置样式
display: inline-block;
