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 🙏

localStorage 兼容IE 等

[功能描述]

给不支持本地存储的浏览器创建一个 window.localStorage 对象来提供类似接口

该对象支持以下方法或属性

  • setItem : function(key, value)
  • getItem : function(key)
  • removeItem : function(key)
  • clear : function()
  • length : int
  • key : function(i)
  • isVirtualObject : true

二次包装的接口 window.LS 提供以下方法和属性（如果有jQuery则同样会扩展该对象），推荐使用

  • set : function(key, vlaue)
  • get : function(key)
  • remove : function(key)
  • clear : function()
  • each : function(callback) callback接受两个参数 key 和 value
  • obj : function() 返回一个对象描述的localStorage副本
  • length : int

[已知问题、使用限制]

  • 原生本地存储的key是区分大小写的，模拟对象不区分（因为userData不区分key的大小写）
  • 模拟对象的 clear 方法仅仅能清理通过本组件设定的数据
  • 模拟对象的实际的存储容量跟原生本地存储有差异
  • 模拟对象不支持任何localStorage事件件
