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 🙏

2.2 Create and automatically start a 60s countdown

创建并自动开启一个60s的倒计时

new CountDown(60000, { cdType: 's' }, cd => console.log(cd.s));

2.3 Create a countdown that accurate to milliseconds

创建一个可以显示毫秒的定时器

new CountDown(10000, { interval: 50 }, ({ss, SSS}) => {
  console.log(`${ss} ${SSS}`);
});

2.4 Create a 60s countdown and start it manually

创建一个60s倒计时,手动开始和结束

const cd = new CountDown(60000, { autoStart: false }, () => {
  console.log(cd);
});

// A moment later
cd.stop();
// A moment later
cd.start();
// Destory The countdown
cd.destory();

3 Interface 接口

/**
 * Time,倒计时时间
 */
type CountDownTime = number | null | undefined;

/**
 * Initial Options, 倒计时初始化参数
 */
interface CountDownOptions {
  // 倒计时步进间隔,默认: 1000
  interval?: number;
  // 是否自动开启,默认为: true
  autoStart?: boolean;
  // 倒计时类型,d: 到天,h: 到小时,m: 到分钟,s: 到秒,S: 到毫秒,默认:'h'.
  cdType?: 'd' | 'h' | 'm' | 's' | 'S';
}
 
/**
 * CountDown 构造定义
 */
declare class CountDown {
  time: number | null;             // 倒计时时间
