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 🙏

F6-UI

基于 G 的简易 UI 系统,可以结合 F6 快速实现 UI 布局。适合小范围的在 canvas 上的布局。

  • 支持 html+css
  • 支持 flex 布局
  • 支持事件
  • 支持重排
  • 支持重绘

标签支持

| Tag | 描述 | | ------------------------ | ------------ | | root | 根节点 | | div | 容器节点 | | image | 图片节点 | | text(文本自动隐式创建) | 文本节点 | | shape | G 中的 shape |

css 支持

| 属性 | 值/示例 | | --- | --- | | width/height/min/max-width/heihgt | number | | top,left,right,bottom | number | | pading, padding-left/top/right/bottom | number | | margin, margin-left/top/right/bottom | number | | overflow | hidden | | display | 'flex' , 'none' | | position | 'absolute' | | flex-direction | 'column', 'row' | | flex-wrap | 'wrap', 'nowrap' | | justify-content | 'flex-start', 'center', 'flex-end', 'space-between', 'space-around' | | align-items/ align-self | 'flex-start', 'center', 'flex-end', 'stretch' | | align-content | 'flex-start', 'center', 'flex-end', 'stretch' | | border | | | border-width | number | | border-style | 'solid', 'dashed' | | border-radius | number | | color | 颜色名称 / #xxx / rgb() / rgba() | | font-family | | | backgroud-color | 颜色名称 / #xxx / rgb() / rgba() | | pointer-events | none |

  • 目前文本和 shape 标记不能计算出宽高,不参与布局,文本需要使用 div 将文本包起来,定义该 div 的宽高。shape 可以直接在 css 中定义 shape 的宽高

example

相对比较复杂的案例可以参考 F6-plugin package 下的 timebar 控件。下面是一个简单的示例:

import F6 from '@antv/f6';
import { createUI } from '../../../f6-ui';

function runTestUI(group) {
  const html = `
    <root id="lll">
      <div class="test">
        <shape type="polygon" points = "[
          [0, 0],
          [0, 80],
          [80, 80],
          [80, 0]
        ]" />
        <shape class="circle" type="circle" r="30" />
        666
      </div>
      <div class="real">       
       <image src="https://gw.alipayobjects.com/mdn/rms_6ae20b/afts/img/A*N4ZMS7gHsUIAAAAAAAAAAABkARQnAQ"></image>
      </div>
      <div class="test">test</div>
      <div class="real">test</div>
    </root>
  `;
  const css = `
    #lll {
      /** 盒模型 **/
      width: 500;
      height: 400;
      padding: 0 0;
      margin: 100 100;
      border: 10 solid rgba(0,0,0,1);

      /** flex **/
      display: flex;
      flex-direction: row;
      flex-wrap: nowrap;
      justify-content: center;
      align-items: center;

      /** 基础绘制 **/
      background: blue;
      border-radius: 5;

      /** 继承 **/
      color: red;
      font-size: 24;
      text-align: center;
    }

    /** 优先级 **/
    #lll div.real{
      background: yellow;
    }
    
    /** 选择器组合 **/
    #lll div{
      background: red;
      margin-left: 10;
      width: 100;
      height: 100;
    }
    
    shape {
      position: absolute;
      background: #ff00ff;
      top: 10;
      left: 10;
      width: 80;
      height: 80;
    }

    .test {
      padding-top: 35;
      color: white;
    }
    shape.circle {
      top: 50;
      left: 50;
      background: black;
    }
    image {
      width: 50;
      height: 50;
    }
  `;
  createUI(html, css, group);
}
