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 🙏

      })
      </script>

用法

  1. 参数

    <TimerCountdown
      :deadline="倒计时剩余时间-秒(必填)"
      :complete-zero="补全0(true)"
      :left-second="提前到期-秒(0)"
      :ignore-day="true:展示到小时;false:展示到天(true)"
      @done="倒计时结束后回调的方法"
      @update="每秒渲染结束后回调的方法,带参数{ day, hour, minute, second, restSecond }(展示的天、小时、分钟、秒,总共剩余的秒)"
    />

    任何时候(包括已经结束后触发done之后),修改deadline都可以让组件重新启动。

  2. 插槽

    <TimerCountdown
      :deadline="倒计时剩余时间-秒(必填)"
      v-slot="time"
    >
      {{ time.day }}天
      {{ time.hour }}时
      {{ time.minute }}分
      {{ time.second }}秒
    </TimerCountdown>

Tips

因为传递的deadline是剩余秒数,而不是时间戳,所以如果想要重启同一个秒数的倒计时,需要想办法触发,比如先设置deadline为其他值然后再设置回去。(如果改为时间戳实现就可以规避前面说的问题,但是使用者就要每次传入倒计时秒数 + Date.now()
