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

An entity designer for typeorm, based on fabric.js.

@see http://fabricjs.com/ @see https://typeorm.io/#/separating-entity-definition

1. Intro

TypeORM Entity Designer 是一个用来在页面上绘制 ER 图的小工具,底层基于 fabricjs ,这个小工具可以自动生成 typeorm 规定的 Schema 格式,方便与 typeorm 进行对接。

内部只有 2 个核心类:Entity & Relation ,分别对应“实体”和“关系”。

只依赖以下 3 个 node 模块:

  • "fabric": "^4.4.0",
  • "pluralize": "^8.0.0",
  • "uuid": "^8.3.2"

其中 pluralize 和 uuid 已经被打包进去,fabric 需要使用 script 标签加载。(fabric 当前版本没有提供 ES 模块加载的方式。)

2. Usage


<!DOCTYPE html>
<html>
  <head>
    <title>Group</title>
    <script src="../node_modules/fabric/dist/fabric.js"></script>
    <script src="../dist/index.umd.js"></script>
  </head>
  <body>
    <div><canvas id="container" style="border: 1px solid #ccc" width="1024" height="768"></canvas></div>
    <script>
      let canvas = new fabric.Canvas('container', {
        preserveObjectStacking: true,
      });

      let boEntity1 = new fabric.BoEntity([], {
        width: 200,
        height: 100,
        fill: '#fee',
        stroke: '#000',
        padding: 5,
        linkable: true,
        title: 'testtesttesttesttesttesttesttesttesttesttest',
        fields: [
          {
            name: 'userName',
            type: 'String',
          },
          {
            name: 'userName',
            type: 'String',
          },
          {
            name: 'userName',
            type: 'String',
          },
          {
            name: 'userName',
            type: 'String',
          },
          {
            name: 'userName',
            type: 'String',
          },
          {
            name: 'userName',
            type: 'String',
          },
        ],
      });
      canvas.add(boEntity1);

      let link1 = new fabric.Link([500, 500, 300, 300], {
        stroke: '#f00',
        fill: '#f00',
        arrowType: 'both',
      });
      canvas.add(link1);

      link1.setLinkTo(boEntity1);

      let boEntity2 = new fabric.BoEntity([], {
        width: 200,
        height: 100,
        fill: '#fee',
        stroke: '#000',
        padding: 5,
        linkable: true,
        title: '2222',
        fields: [
          {
            name: 'userName',
            type: 'String',
          },
        ],
      });
      canvas.add(boEntity2);

      link1.setLinkFrom(boEntity2);

      console.log(canvas.toJSON());
      console.log(JSON.stringify(canvas));
    </script>
  </body>
</html>

注意:由于 fabric.js 是采用 ES5 语法编写的,没有支持 ES6 模块,ted 也采用了相同的技术栈来扩展功能,所以目前只能使用 <script> 标签的方式进行引入。
