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 🙏

wmf-kgraph(威士顿知识图谱组件)

Wisdom framework Department language language

概述

威士顿知识图谱组件是知识图谱应用的可视化关系展示图。

快速上手

引用 wmf-kgraph

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <script src="wmf-kgraph-x.x.x.min.js"></script>
  </head>
</html>

绘制一个简单的图

在绘图前我们需要为 wmf-kgraph 准备一个定义了高宽的 DOM 容器。在刚才的例子 之后,添加

<body>
  <div id="main" style="width: 600px;height:400px;"></div>
</body>

然后就可以通过 wmfGraph.draw 方法初始化一个 wmfGraph 实例并生成一个简单的关系图,下面是完整代码。

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <title>wmf-kgraph</title>
    <script src="wmf-kgraph-1.0.0.min.js.js"></script>
  </head>
  <body>
    <div id="main" style="width: 600px;height:400px;"></div>
    <script type="text/javascript">
      wmfGraph.draw("main", {
				nodes: [
					{ data: { id: 'a', label:'a', detail:'a desc' } },
					{ data: { id: 'b', label:'b', detail:'b desc' } }
				],
				edges: [
					{ data: { id: 'ab', source: 'a', target: 'b', label:'ab' } }
				]
			})
    </script>
  </body>
</html>

API

事件绑定

/// 事件绑定
/// -- eventName	事件名称
/// -- eventHandle	事件处理句柄
wmfGraph.on(eventName, eventHandle)

/// 使用方法

// 菜单事件绑定(menuClick)
wmfGraph.on("menuClick", function (menuName, node){
	if(menuName) // TODO
})

// 节点点击事件
wmfGraph.on("nodeclick", function (node, grapher) {
	console.log("执行了点击事件 node data", node.data())
	// 返回false阻止默认事件(关闭菜单...)
	return true
})

设置点击菜单

/// 设置节点点击菜单
/// -- menus    菜单选项
/// -- nodeOrId 节点或节点Id(设置单个节点时使用)
///	   单个菜单已数据里的菜单为准(data.menus)
wmfGraph.setMenus(menus, nodeOrId)

// 使用方法
wmfGraph.setMenus([
	{ name: "expand-node", title: "展开节点" },
	{ name: "remove-node", title: "删除节点" },
	{ class: "wsd-split" },
	{ name: "update", title: "更新数据" },
	{ name: "update-edge", title: "调整线条" },
	{ class: "wsd-split" },
	{ name: "addani", title: "添加动画" },
	{ name: "removeani", title: "删除动画" }
])

// 菜单事件监控
wmfGraph.on("menuClick", function (eventName, node) {
	if (eventName === 'expand-node') {
		// TODO
		return 
	}
})

添加节点

/// 添加节点
/// -- elements 节点元素数据(节点+关系)
wmfGraph.addNode(elements)

// 使用方法
wmfGraph.addNode({nodes:[{data:{id:'a2',label:'a2',detail:'a2 desc'}},{data:{id:'b2',label:'b2',detail:'b2 desc'}}],edges:[{data:{id:'a2b2',source:'a2',target:'b2',label:'ab'}}]})

删除节点

/// 删除节点
/// -- nodeOrId  节点对象或节点Id
wmfGraph.removeNode(nodeOrId)

展开节点

/// 展开节点
/// -- nodeOrId     节点对象或节点Id
/// -- subElements  子节点元素数据(节点+关系)
wmfGraph.expandNode(nodeOrId, subElements)

更新节点数据

/// 更新节点数据
/// -- nodeOrId  节点对象或节点Id
/// -- data      数据(menus菜单数据,animation动画数据....)
wmfGraph.updateNode = function(nodeOrId, data)

// 使用方法
wmfGraph.updateNode('a', {
						label:"11111", 
						image:'./images/warning.png',  
						detail: '<div style="color:red;">新的详细信息</div>',
					})

添加动画

/// 添加动画
/// -- nodeOrId  节点对象或节点Id
/// -- animation 动画配置
///    {name:'flash', style:{'border-with':10, 'border-color':'red'}, duration: 1000}
wmfGraph.addNodeAnimation(nodeOrId, animation)

// 使用方法
wmfGraph.addNodeAnimation('a', { name: 'flash' })

删除指定动画效果

/// 删除指定动画效果
/// -- nodeOrId  节点对象或节点Id
/// -- name      动画名称
wmfGraph.removeNodeAnimation(nodeOrId, name)

// 使用方法
wmfGraph.removeNodeAnimation('a', 'flash')

更新线条数据

/// 更新线条数据
/// -- edgeOrId   线条对象或线条id
/// -- data       更新的数据
wmfGraph.updateEdge(edgeOrId, data)

/// 设置节点点击菜单
/// -- menus    菜单选项
///             [{name:'menu1',title:'菜单1'}...]
