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 🙏

API

createActions()

此方法生成实例为图谱展示的数据管理实例,必不可少;

actions.addData(GraphData, isReplace = false)

往当前图谱中添加数据,数据格式固定;isReplace 为 true 的时候会替换当前所有数据

actions.savePic(fileType)

当前图谱保存为图片,格式支持 jpeg|png|svg

actions.adaption(padding=30, minScale=undefined)

自适应当前视图大小;padding为四周间隔,minScale为最小缩放量

actions.zoomIn(step=0.1)

放大,setp 为百分比

actions.zoomOut(step=0.1)

缩小,setp 为百分比

actions.zoomTo(scale)

缩放为原图的 scale 倍

actions.relayout()

重新布局

actions.focus(nodeId)

聚焦到某个节点

Layout

内置了以下布局,可以在 ReactGraph 里配置

{
    force: '力导布局',
    tree: '树形布局',
    grid: '网格布局'
}

如果需要实现自定义布局,需要继承BasicLayout类实现

utils

shortestPath

最短路径计算

fullPath(number)

n 度以内全路径计算

isomorphicAnalysis(GraphData)

同构图分析,返回分析后的同构图

数据说明

Node

{
    id: String,
    type: String,
    label: String,
    x: Number,
    y: Number,
    nodeSize: Number,
    mode: String<default|highlight|unHighlight>,
    ...other
}

Edge

{
    id: String,
    target: String,
    source: String,
    type: String,
    label: String,
    strokeWidth: Number,
    isDirected:false,
    ...other
}

GraphData

{
    nodes: Node[],
    edges: Edge[]
}

其他

注意:如果需要兼容 ie11,打包的 babel 的配置里面请不要排除d3-forced3-quadtreed3-timer,因为他们内部包含了箭头函数、const

规划功能

动画:路径分析后出来的结果是否可以以动画的形式展示 eg: pipe(animate(node1), animate(edge1), animate(node2), animate(edge2), animate(node3))

图形扩展:圆形、矩形、椭圆
