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 🙏

思考如下问题: 当我们需要延迟执行代码,这种情况一多,我们就需要同时创建很多个定时器。当我们的页面同时持有很多定时器的时候,这会耗费很多不必要的计算机资源。 ```javascript setTimeout(() => {}, 100) setTimeout(() => {}, 200) setTimeout(() => {}, 300) setTimeout(() => {}, 400) setTimeout(() => {}, 500) ... ```

思考如下问题: 当我们需要延迟执行代码,这种情况一多,我们就需要同时创建很多个定时器。当我们的页面同时持有很多定时器的时候,这会耗费很多不必要的计算机资源。

setTimeout(() => {}, 100)
setTimeout(() => {}, 200)
setTimeout(() => {}, 300)
setTimeout(() => {}, 400)
setTimeout(() => {}, 500)
...

试想,我们是否可以只使用一个定时器来完成上述的逻辑,也就是说我们只需要依次设置一个100ms的定时器,在前一个定时器完成后,才设置下一个定时器。

setTimeout(() => {
  setTimeout(() => {
    setTimeout(() => {
      ...
    }, 300- 200)
  },200 - 100)
},100)

OneTimer最终完成的事情就是这个。

npm i --save one-timer

import OneTimer from 'one-timer/dist/OneTimer.es.js'

let oneTimer = new OneTimer()
oneTimer.push(100, () => {})
oneTimer.push(200, () => {})
oneTimer.push(300, () => {})
oneTimer.push(400, () => {})
oneTimer.push(500, () => {})
...

如上,不管你需要执行多少个定时逻辑,持有的定时器永远只有一个。

let id = oneTimer.setTimeout( () => {}, delay)
oneTimer.clearTimeout(id)
  • oneTimer.pause
  • oneTimer.restart

oneTimer.pause()
onetTimer.restart()
