snaker工作流引擎web设计器(vue3版)

情怀！N年前使用的工作流引擎，虽然原作者已经不再维护，但是还是有那么一波人还在使用。个人看来其核心功能尚好，麻雀虽少，五脏俱全，是用来学习工作流引擎的好项目。但其流程设计器所用的技术栈可能就跟不上时代了（2016年前的开源项目）。为了让大伙或自己用得更舒心，或者也为了让更多人认识或重新认识这个工作流引擎。本人就花些许时间，使用现阶段前端主流的技术栈重新开发此款流程设计器。如大家在使用的过程中如有啥问题，欢迎留言或进群交流！

如何使用

安装

npm install snakerflow-designer-vue@next --save

其他依赖

设计器依赖以下第三方库，如果工程中没有引入这些第三库将会无法正常使用，需自行安装。

npm install @logicflow/core@^1.1.28 --save
npm install @logicflow/extension@^1.1.28 --save
npm install clipboard@^2.0.11 --save
npm install vue-json-pretty@^2.1.1 --save

引入

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
// 导入组件库
import SnakerFlowDesigner from 'snakerflow-designer-vue'
createApp(App).use(router).use(ElementPlus).use(SnakerFlowDesigner).mount('#app')
