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

bpmnjs+Vue3

这是基于 bpmnjs 和 vue3 的组件,实现流程图绘制和流程图解析功能

使用方法

npm i bpmn-vue-temp -save

全局引入(支持按需引入)

import { createApp } from "vue";
import App from "./App.vue";
//引入样式
import "bpmn-vue-temp/lib/style.css";
//引入组件
import BpmnVueTemp from "bpmn-vue-temp";
//全局引入
createApp(App).use(BpmnVueTemp).mount("#app");

工作流画布组件

使用方式

按需引入时组件名叫BpmnCanvas,全局引用时组件名为Bpmn-Vue

1.组件方式

import { ref } from "vue";
import { BpmnCanvas } from "bpmn-vue-temp";
let bpmnRef = ref();

<template>
  <div class="box" id="bpmn">
    <BpmnCanvas :bpmnID="'test'" ref="bpmnRef" @select:element="selectElement" />
  </div>
</template>


// 全局引入使用
<template>
  <div class="box" id="bpmn">
    <Bpmn-Vue :bpmnID="'test'" ref="bpmnRef" @select:element="selectElement" />
  </div>
</template>

2.自定义方式

import { useBpmnCanvas } from "bpmn-vue-temp";

let bpmn = useBpmnCanvas();
bpmn.initModeler({
  container: document.getElementById("bpmn"),
  additionalModules:{},
  moddleExtensions:{}
});
/*
 * bpmnID :string 画布ID
 * isReadOnly :boolben 是否开启只读
 * options : object 自定义配置
 * operation : array 自定义操作,是一个操作数组,包含{label,icon,action}对象,目前自带有['导出XML','导入XML','导出SVG','放大','缩小','重置']
 * */

组件对象和事件

import { ref } from "vue";
import { BpmnVue } from "bpmn-vue-temp";
let bpmnRef = ref();
//通过ref获取可以获得当前画布的事件对象

function selectElement(info) {
  //info中包含了businessObject:节点存储的业务对象,shapeType:节点类型
  console.log(info);
}

<template>
  <div class="box" id="bpmn">
    <Bpmn-Vue bpmnID="test" ref="bpmnRef" @select:element="selectElement" />
  </div>
</template>

API

/**
 * options:{
 *   container:画布节点 选择器或dom元素
 *   additionalModules:{} 个性化配置
 *   moddleExtensions:{} 扩展moddle
 * }
 */
initModeler(options);

//获取图中所有节点
getShapeAll()
//根据节点id获取节点对象
getShapeById(id: any)

//获取xml数据
getXML()

//更新节点数据
updateProperties(element: ModdleElement, properties: PropertiesMap<any>)
//例子
function textareaChange() {
    const moddle = state.bpmnStore.getModdle();
    let conditionExpression = moddle.create('bpmn:FormalExpression', {
      body: '哈哈哈',
    });
    state.bpmnStore.updateProperties(toRaw(state.bpmnStore.getActiveElement().element), {
      conditionExpression,
    });
}

//导入xml生成数据
importXML(string: string)

//导出xml
exportXML()

//导出SVG
exportSVG()

//重置数据
resetData()
