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 🙏

Readme

基于@antv/g6的边拖拽连线组件

使用

import {edgeDragLinkNode, stateName as edgeStateName, edgeDragLinkBehavior, edgeDragArrow} from '@alone-g6/edge-drag-link';
const EdgeDragLinkNode = edgeDragLinkNode();

1、在自定义节点的afterDraw函数调用该组件的afterDraw用于生成拖拽辅助点shape

afterDraw(cfg, group) {
    EdgeDragLinkNode.afterDraw(cfg, group);
  }

2、在合适的时机设置edge-drag-link为激活状态,用于显示拖拽点

setState(name, value, item) {
    EdgeDragLinkNode.setState(name, value, item);
}

3、使用交互

G6.registerBehavior(edgeDragLinkBehavior.name, edgeDragLinkBehavior);
modes: {
  default: ['drag-node', edgeDragLinkBehavior.name],
}

4、使用箭头拖拽

G6.registerEdge('some-name', edgeDragArrow, 'line');

节点参数

  • markerStyle: 辅助点的样式
  • getAttr: 动态获取attr属性function(value, item, shape)
  • stateChanged: 状态变更事件function(value, item, shape)

交互参数

  • shouldBegin(e): 是否允许当前被操作的条件下开始创建边
  • shouldEnd(e):是否允许当前被操作的条件下结束创建边

交互事件

  • edge-drag-link:end:当边创建完成时将会触发该时机事件。使用 graph.on('edge-drag-link:end', edge => {...}) 监听。其参数 edge 字段即为刚刚创建的边。
