1、现阶段比较热门的流程图组件库

2、LogicFlow

1、全局安装logicflow插件

1、npm install @logicflow/core -S                 //核心功能
2、npm install @logicflow/extension --save        //扩展功能

2、页面内引用文件

import LogicFlow from '@logicflow/core';
// 引入整体背景的样式
import '@logicflow/core/dist/index.css';
import { Control,DndPanel } from '@logicflow/extension';
// 引入 extension相关操作的样式
import '@logicflow/extension/lib/style/index.css';

3、设置容器的宽高

<template>
  <div class="ViewEditor">
    <div ref="Container" class="viewport" />
  </div>
</template>

<style scoped>
.ViewEditor {
  height: 100vh;
}
.viewport {
    height: 100%;
 }
</style>

4、设置js内容以及执行代码

 data() {
    return {
       lf: null,
      config: {
        stopZoomGraph: true, // 禁止缩放
        // 背景网格大小
        grid: {
          size: 10,
          type: "dot",
        },
        keyboard: {
          enabled: true,
        },
        snapline: true,
      },
    };
  },
  mounted() {
    // 初始项目注册
    this.lf = new LogicFlow({
      ...this.config,
      container: this.$refs.Container,
       plugins: [Control, DndPanel],
    });
    this.lf.render();
 this.lf.extension.dndPanel.setPatternItems([
      {
        type: "circle",
        text: "开始",
        label: "开始节点",
