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 🙏

Readme

countUp: new zpm.sys.web.number.countUp(target, startVal, endVal, decimals, duration, options)

参数:

target: 目标元素的id *必填 startVal:开始的值(从哪个值开始) *必填 endVal:结束的值(滚动到哪个值结束) *必填 decimals:小数位数,默认值为0 *可选 duration:动画持续时间,单位为秒,默认值为2 *可选 options:选项的可选对象 *可选 useEasing:true --是否使用缓动动画,默认为缓动,可设置为false让其匀速

                 useGrouping:true --对数字进行分组,如12345,按三位一组变为类似12,345这样的

                 separator: ','  --分组时使用的分隔符默认是逗号

                  decimal: '.'  --小数点

                  prefix: ''  --添加前缀如12345,变为¥12345

                  suffix: ''  --添加后缀如12345 通过添加后缀变为12345$,12345元之类的

方法:

暂停/恢复 pauseResume 重置动画 reset 更新值 update(newVal)

例如: numberScroll() { let count = new CountUp("numScroll", 0, 56565, 0, 5, {duration: 5, useEasing: false}) if (!count.error) { count.start() } else { console.log(count.error) } }

setInterval(() => { count.update(count.endVal); }, 1000);
