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 🙏

ColorData

Data Visualization with canvas and d3

数据可视化

  • 基于canvas/svg

  • 关系拓扑图

  • 流程逻辑图

  • json数据结构化

  • 节点数据刷新图像重绘(diff算法)

应用条件

需要将json数据的派生结构 转换为 可视化数据图形

例子

const data=[
  {
    name: `node-${new Date().getTime() * Math.random()}`, // 节点图名称/id
    text: '', // 图中显示字样
    isShow: true, // 是否默认显示图
    type: 0, // 0:方框图 1:菱形图 2:椭圆图 3:四边形图
    value: null,  // 节点图所代表值 [object | string | number | boolean]
    events: {
      'mousedown':function(data,_ev){}, // 绑定事件名 : 绑定事件(冗余参数,事件对象)
    },  // 节点图所绑定事件
    x: 0, // 节点图中心点x坐标值
    y: 0, // 节点图中心点y坐标值
    width: 160, // 节点图宽度
    height: 40, // 节点图高度
    children: [], // 节点图子节点
  }
];

当json数据输入给本插件,由本插件转化为可视化拓扑图像

测试

基于三大框架(vue/angular/react)搭建的平台中,进行测试和项目优化
