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 🙏

基于React的开源可拖拽图渲染库。

Readme

Easy-Graph

🔖首届支付宝前锋营进阶课「都不队」小组结业项目。

🏷️开源:基于 React 的开源 可拖拽 图渲染和布局库。

🪶轻量:除 React 外无第三方依赖。

🚀简洁:内置多种布局算法 给您快捷多样的体验。

🌹 自由:高度可定制 支持自定义注册节点样式和边样式。

🐥 功能丰富:节点支持拖拽 图会响应式渲染 画板支持缩放 平移。

🦚支持导入导出:支持导入导出数据。

使用方法:

安装:

npm i easy-graph

快速开始:

1.导入组件

import { EGProvider, EGContext,useRegister } from 'easy-graph';

2.自定义组件 (若使用默认组件,可跳过)

边:

const YourEdge: CustomEdge<YourData> = ({
    edgeId:string;
    startEndPosition:[number,number,number,number];
    data:YourData;
})=>{
    return (
       //消费数据的组件
    )
}

节点:

const YourNode: CustomNode<YourData> = ({
    nodeId:string;
    data:YourData;
})=>{
    return (
       //消费数据的组件
    )
}

3.注册自定义组件

{
    [elementType:string]:Element;
}

4.渲染图

首先要先初始化要消费的数据,其中

nodes是形如下面的对象的数组

interface NodeProps{
    nodeType:string;//对应注册的组件
    nodeId:string;//唯一id
    position:[number, number];//位置
    data?:any;//自己的组件要消费的数据
}

edges是形如下面的对象的数组

interface EdgeProps{
    edgeId:string;//边的id
    edgeType:string;//对应注册的组件
    startEndNodeId:[string,string];//两个端点的id
    data?:any;//自己的组件要消费的数据
}

最后

<EGProvider>
    <EGContext
        nodes={nodes}
        edges={edges}
        regist={elements}>
    </EGContext>
</EGProvider>
