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 🙏

  • parseDate (t):转为日期对象
    • t:时间戳或fmt(参考上述fmt示例)
  • getTextAgo (d):将时间转为文字描述
    • d:日期对象、时间戳或fmt,转换规则:
      • 刚刚(一分钟内)
      • x分钟前
      • 今天 x时x分
      • 明天 x时x分

url(路由处理)

  • encodeUrl (url):加密url
  • decodeUrl (url):解密url
  • getQueryString (name, url = window.location.search, decode = false):获取url中的参数
    • name:获取的名称
    • url:从这个url中获取
    • decode:是否需要解密
  • toQueryString (params, encode = false):将对象格式转换为url的query
  • parseQueryString (url = window.location.search, decode = true):将url中的所有参数解析为一个对象
  • formatUrl (url, params, encode = false):将参数追加到url后面
  • parseUrl (url):将url转换成对象格式,形如location,返回值有:
    • hash
    • host
    • hostname
    • href
    • origin
    • pathname
    • port
    • protocol

data(数据转换)

  • getDeepData (data, chain, dft):获取对象的深层值,防止报错
    • data:原始对象
    • chain:需要取值的链,如:time.start,表示取data.time.start的值
    • dft:若不存在则返回该值
  • parseJSON (str):字符串转为json对象
  • toArray (args, start = 0):类数组转换为数组,可以调用数组方法
  • fillArray (start, end):按照数字顺序填充数组,如:fillArray(1, 100),则返回一个包含1~100的数组
  • randomArray (array, count):将数组打乱,返回一个新数组,第二个参数可以设置新数组的长度
