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 🙏

ReGraph

数据领域图表定义:以树、图为基础数据结构,带有数据业务属性与特征的图表

现状与痛点

  • 数据产品中领域图表较多,业务场景丰富
  • 产品中领域图表交互实现方式不统一
  • 领域图表开发成本高,几乎都需要个性化开发
  • 在树与图的渲染与交互上,比较成熟,但在布局上,对于开发者而言,门槛很高,直接使用第三方库也很难上手,很难调整到理想情况

ReGraph针对以上痛点,打造了基础操作层、渲染交互层、布局算法层三层结构。

ReGraph = 计算(布局插件)+ 底层操作(树图基础库)+ 渲染(交互的统一封装)

安装

yarn add regraph-next

ReScreen

ReScreen 组件统一封装了画布的操作和缩略图功能,支持对画布的全屏、复位、显示所有、重置、平移缩放等常见功能。

使用

import { ReScreen } from 'regraph-next';

<ReScreen  
  height = {500}
  width = {500}
  mapWidth = {200}
  mapHeight = {200}
  mapPosition = "RT-IN" >
  <svg>
    <g>
      <circle cx={0} cy={0} r={500} fill="yellow" />
      <circle cx={cx} cy={cy} r={250} fill="red" /> 
    </g>
  </svg> 
</ReScreen>

API

BaseGraph

BaseGraph 以树、图为基础数据结构,规范数据定义并提供基础操作库。

功能

  • 插入/删除/替换/查找节点/子树
  • 插入/删除/替换/查找边
  • 获取父节点/子节点/子孙节点/兄弟(层级结构/扁平结构/排序规则)
  • 获取两个子节点的相同父节点
  • 获取子节点到 任意节点(跟节点)的路径

  • 插入/删除/替换/查找节点
  • 插入/删除/替换/查找边
  • 获取父节点/子节点/子孙节点/兄弟(层级结构/扁平结构/排序规则)

BaseLayout

BaseLayout 主要处理树图布局集成

使用方式

import { ReLayout } from 'regraph-next';
const { DAGAIU } = ReLayout;
interface MyRelation {
  sourceId: number;
  targetId: number;
  periodDiff: number;
}
interface MyNode {
  id: number;
  downRelations: MyRelation[];
  upRelations: MyRelation[];
  name: string;
  desc: string;
  nodeWidth?: number;
  nodeHeight?: number;
}
// 生成dag图
const dag = new DAGAIU<MyNode, MyRelation>({
  isTransverse: true,
  padding: 20,
});
  • 生成单个DAG
dag.getSingleDAG(data)
  • 生成多个DAG
dag.getMultiDAG(data)
  • 带组的图布局
this.groupLayout = new GroupGraphLayout(nodes, links, groups, groupLinks, config);
this.groupLayout.layout();
