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 🙏

API
      init:function(){
          // 在组件mounted后的手动初始化方式,方便多次初始化而不用去重新载入组件。
      } 
      addItemBox:function(item){
          // item:布局方框,属性值应和props中的yourList数组对应的对象相同
      }
      removeItem:function(index){
          // index:方框所在list中的下标
      }
      getList:function(){
          //此方法返回将yourList数组, 并且提供原本数组的index
          return sortedList; 
      }
      getMaxCell:function(){
          //此方法返回当前宽度下每行的最大单元格个数
      }    
指定拖动和缩放触发器
    vue-power-drag默认以.item元素作为拖动触发器,以方格右下角的三角形为缩放触发器,
    如果需要指定其他元素作为拖动触发器,可以为xx元素指定.dragHandle类名
    同样,如果要指定xx元素作为缩放触发器,那么可以指定.resizeHandle类名
适配各个分辨率的屏幕

可以参考 src/test.vue里的102行的做法。

    //屏幕适配,使得当前布局能在所有分辨率下适用,示例是在1366*638分辨率下完成
    let screenWidth = window.innerWidth; // 当前屏幕的宽度
    let screenHeight = window.innerHeight; // 当前屏幕的高度
    this.baseWidth = 90.8333 * (screenWidth / 1366); // 假设这里我们设置vue-power-drag的最小单元格宽度为90.8333px,那么他在其他分辨率的屏幕上应该是该屏幕宽度与原本设置90.8333px的屏幕宽度的比值*90.83333
    this.baseHeight = 100 * (screenHeight / 638); // 以此类推
    this.baseMarginLeft = 20 * (screenWidth / 1366);
    this.baseMarginTop = 20 * (screenHeight / 638);
