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 🙏

workflow-bpmn-modeler-antdv

NPM Version NPM Downloads

🔥 本项目基于 vue[email protected] ,实现 flowable 的工作流设计器

🔥 本项目基于 workflow-bpmn-modeler 进行了Ant Design Vue的适配,初始版本基于0.2.8发展适配为antdv下的1.0.1版本

🔥 本项目基于 workflow-bpmn-modeler 如果需要Element UI版本可以直接访问原仓库

本项目代码去除原有表单XFORM组件,整体改的有点冗余,前端功底较差

预览 📟

1.0.2

在线 demo 📢

👉 https://vincent-vic.github.io/workflow-bpmn-modeler-antdv/demo/

安装 ⏳

# yarn
yarn add workflow-bpmn-modeler-antdv
# Or npm
npm i workflow-bpmn-modeler-antdv

更新日志

1.0.1 更新说明

  • 基于workflow-bpmn-modeler适配为Ant design vue版本,功能大致相同
  • 修复信号bug
  • 添加消息 安装后引入
import bpmnModeler from 'workflow-bpmn-modeler-antdv/package/';

1.0.2 更新说明

  • 优化依赖
  • 分类支持树状结构
  • 优化面板显示
  • 调整分配部分逻辑 安装后引入
import bpmnModeler from 'workflow-bpmn-modeler-antdv';

1.0.3,1.0.4 废弃

1.0.5 更新说明 is-view 无效修复

注意事项

在部分系统中存在侧边栏层级覆盖本身系统组件,可参考设置层级

/deep/ .ant-layout-sider{
  z-index: 2;
}

组件使用AntdvUI,但UI需要自行配置,如果版本缺少组件根据报错自行加入全局 例如:

import { FormModel } from 'ant-design-vue';

Vue.use(FormModel);

文档建议参考代码仓库为准

iframe 部署 🎪

如果你的项目是 jquery 或 react 类项目,可以通过 iframe 的方式集成该流程设计器

本仓库通过 github pages 部署了静态页面,使用 jsdelivr 做 cdn ,国内访问也非常快速,所以你可以直接集成本仓库的页面,因为全部白嫖了 github 的资源,没有自己建服务器维护,所以不用担心资源失效问题。

当然你也可以在 docs/lib 文件夹下下载对应的版本,进行本地部署。

集成方式如下(ps:可直接拷贝以下代码到一个html文件中试一下):

<!DOCTYPE html>
<html lang="en">
  <body>
    <iframe
      src="https://vincent-vic.github.io/workflow-bpmn-modeler-antdv/cdn/1.0.1/"
      id="myFrame"
      frameborder="0"
      width="100%"
      height="800px">
    </iframe>

    <script>
      let myFrame = document.getElementById("myFrame");
      // 获取到流程详情
      window.addEventListener("message", (event) => {
        console.log(event.data); // { xml: 'xxx', img: 'xxx', process: {} }
      });
      myFrame.onload = () => {
        let postMsg = {
          xml: "", // 后端查询到的xml,新建则为空串
          users: [
            { name: "张三1", id: "zhangsan" },
            { name: "李四1", id: "lisi" },
            { name: "王五1", id: "wangwu" },
          ],
          groups: [
            { name: "web组1", id: "web" },
            { name: "java组1", id: "java" },
            { name: "python组1", id: "python" },
          ],
          categorys: [
            { name: "OA1", id: "oa" },
            { name: "财务1", id: "finance" },
          ],
          isView: false
        }
        // 设置初始化值
        myFrame.contentWindow.postMessage(postMsg, "*")
      }
    </script>
  </body>
</html>

关于定制 🛠

本组件对标的是 flowable 官方设计器,也就是实现 flowable 的 xml 规则标准,里面所用名词也都是官方文档中的专业术语。所以这个组件只是程序员在开发阶段,自己建模导出 xml 的工具,试图定制该建模器的行为都是不对的,不要把业务带到建模器中来!自己的业务应该另行开发增删改查来实现。

该组件未来也不会升级 UI 库和 vue。不管库是否兼容,通过 iframe 的方式集成建模器才是最简单正确的方式。
