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 🙏

adamjs

  • 自己写的封装一些常用函数的包
  • gitlab地址:gitlab

介绍

  • $ npm install adamjs
  • import adam from adamjs

函数说明

query(name, querystring)

  • 获取指定的 querystring 中指定 name 的 value adam.query('name', '?name=js') //return 'js'

serialize(data)

  • 序列化对象,就是把对象转成 url 字符串 adam.serialize({hello: 'js'}) //return '?hello=js'

$(selector)

  • 根据选择器查找 DOM adam.$(selector) //return {DOM|undefined}

removeNode(node)

  • 删除 DOM 节点 adam.removeNode(node)

insertAfter(node, target)

  • 在 target 节点之后插入 node 节点 adam.insertAfter(node, target)

addClass(node, className)

  • 添加类名 adam.addClass(node, className)

removeClass(node, className)

  • 删除类名 adam.removeClass(node, className)

getAbsoluteUrl(url)

  • 获取绝对路径 adam.getAbsoluteUrl('/hhh') //return 'https://github.com/hhh'

debounce(callback, time)

  • 防抖动函数
  • example
 test('test true', () => {
    const debounce = adam.debounce
    jest.useFakeTimers() // 声明语句,启用jest伪装计时器函数,因为使用了advanceTimersByTime()
    const callback = jest.fn() // 声明语句,使用jest伪装函数
    const createDebounce = debounce(callback, 300)
    expect(callback).not.toBeCalled() // callback还未被调用
    for (let i = 0; i < 11; i++) { // 循环执行createDebounce 11次,每次都在经过299ms时setTimeout被刷新
      createDebounce()
      jest.advanceTimersByTime(299) // 过了299ms
    }
    expect(callback).not.toBeCalled() // callback还未被调用
    jest.advanceTimersByTime(1) // 再过1ms
    expect(callback).toBeCalled() // callback被调用
    expect(callback).toHaveBeenCalledTimes(1) // callback只被调用1次
  })   

removeItemByIndex(index, arr)

  • 根据所以移出数组的某一项 adam.removeItemByIndex(index, arr) // return arr
