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 🙏

//   { name: 'A', age: undefined },
//   { name: 'B', age: undefined },
//   { name: 'C', age: undefined },
//   { name: 'D', age: null },
//   { name: 'E', age: 20 },

const removeListener = draggingScroll(document.getElementById('id'));

// removeListener()

randomId

生成一串随机字符

console.log(randomId());
// lmsimogsk7pukfcia4

isNumber

判断一个字符串是否是数字,科学计数法也会被认为是数字

console.log(isNumber('0.23e-1'));
// true

deepMerge

深度合并对象,只有对象会被合并,其他类型均会被新的值替换

const a = { a: 1, b: { c: 2, d: 3 }, e: 4 };
const b = { a: 1, b: { c: 5, f: 6 }, e: 4 };

console.log(deepMerge(a, b));
// { a: 1, b: { c: 5, d: 3, f: 6 }, e: 4 }

getRootOffset

获取相对位置,默认获取到 html 标签的 offsetTop, offsetLeft

isMobile

判断当前设备是否为移动端设备。依据:userAgent 包含移动端信息并且支持触摸事件,否则降级为使用屏幕宽度判断。

  /**
   * 是否强制使用屏幕宽度检查。
   * 默认为 false。
   */
  forceScreenWidth?: boolean;

  /**
   * 自定义的屏幕宽度阈值(单位为像素)。
   * 默认为 768 像素。
   */
  threshold?: number;

  /**
   * 当 User-Agent 检查结果为 false 时,是否自动降级使用屏幕宽度检查。
   * 默认为 true。
   */
  fallbackToScreenWidth?: boolean;
}
