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 🙏

throttle和debounce

  • click事件我们最常见的就是异步请求一个后台接口,通常我们都只需要执行一次,频繁的执行,响应都是相同的数据没有意义,同时也增加了服务器的压力。这种情况最适合的就是debounce函数;
  • scroll事件如果是触发UI的变化呢,我建议使用throttle。如果是,通过scroll事件加载数据呢则可以使用debounce函数。总之按需取用。
  • resize事件就推荐debounce了,一般情况下只需要在resize结束的时候执行一次回调函数就满足需求了,但是也不是绝对的情况。如果要保持UI的连续性也可以使用throttle函数。
  • mousemove事件一般都是配合UI的改变,因此推荐使用throttle。 现在看一下细分的情况;
  • 滚动加载我们也是在滚动到底部的时候才去加载一次数据,多余的加载都是没有意义的,而且有可能出错,因此使用debounce。
  • 搜索框那就推荐使用throttle了,在合适的间隔去请求搜索结果,既提高了用户体验,又减少了服务器的压力
