简介

  • 是一个基于@antv/x6以及plain-ui-composition封装的Vue3.0可视化流程编辑组件;
  • 旨在于封装开箱即用的常用功能,包括快速定义画布组件、快速定义画布React组件、撤销重做、放大缩小、数据导入导出、冻结画布、拦截新增(删除)节点(边)等功能;

安装

安装依赖

npm i vue-x6-editor plain-ui-compositoin @antv/x6 @antv/x6-vue-shape -S

示例代码

  • plain-ui-composition是一个基于Vue3.0 CompositionAPI封装的插件库,旨在于提供更好的组件与TS类型提示开发体验。
  • 目前仅支持组合式API的方式使用。

JSX使用示例

import {createApp} from "vue";
import {designPage} from 'plain-ui-composition';
import {createBranchNode, createEndNode, createFlowEdge, createFlowNode, createRenderNode, createStartNode, ReactX6Editor, useFlowEditor} from "vue-x6-editor";
import 'vue-x6-editor/dist/vue-x6-editor.css'
import './main.scss';

const App = designPage(() => {

  const editor = useFlowEditor({
    onlyOneStartNode: true,
    operators: [
      {
        label: '选项一',
        icon: () => (<i class="iconfont icon-pay_wechat" style={{ height: '27px', display: 'inline-flex', alignItems: 'center', justifyContent: 'center' }}/>),
        handler: () => console.log('option 1...')
      }
    ]
  });
  editor.components.registry(createStartNode());
  editor.components.registry(createFlowNode());
  editor.components.registry(createBranchNode());
  editor.components.registry(createEndNode());
  editor.components.registry(createFlowEdge());
  editor.components.registry(createRenderNode());

  import('./flow.data.json').then(data => {editor.methods.update(data.default);});

  editor.hooks.onCreateContextmenu.use(({ options, edge, node, type }) => {
    switch (type) {
      case 'node':
        options.push({
          label: '自定义node选项2',
          icon: () => <i class="iconfont icon-pay_zhifubao" style={{ padding: '0 4px' }}/>,
          handler: () => alert('自定义node选项2')
        });
        return;
      case 'edge':
        options.push({
          label: '自定义edge选项',
          icon: 'data',
          handler: () => alert('自定义edge选项')
        });
        return;
      case 'vertex':
        options.push({
          label: '自定义拐点选项',
          icon: 'data',
          handler: () => alert('自定义拐点选项')
        });
        return;
      case 'blank':
        options.push({
          label: '自定义白板选项',
          icon: 'data',
          handler: () => alert('自定义白板选项')
        });
        return;
    }
  });

  return () => (
    <div style={{ height: '100%', width: '100%' }}>
      <ReactX6Editor editor={editor}/>
      {/*<div style={{ position: 'absolute', bottom: 0, right: 0 }}>
        {JSON.stringify(editor.state.data)}
      </div>*/}
    </div>
  );
});

createApp(<App/>).mount('#app');

Template使用示例

  const code = 'render-node';
  return {
    name: custom.name || 'Vue节点',
    icon: custom.icon || 'data',
    code,
    defaultNodeData: ({ config }) => ({
      width: 300,
      height: 100,
    }),
    process: async ({ Graph, config }) => {
      Graph.registerNode(code, {
        inherit: 'vue-shape',
        component: (
          <BaseVueComponent config={config}>
            <DemoRenderNodeContent/>
          </BaseVueComponent>
        ),
        ports: {
          ...createFlowConnectPorts(config),
        }
      }, true);
    }
  };
}
  • DemoRenderNodeContent.tsx
import {designPage, reactive} from "plain-ui-composition";
import './DemoRenderNodeContent.scss';
import {defer, DFD} from 'plain-utils/utils/defer';
import {FlowIcon} from "./FlowIcon";

export const DemoRenderNodeContent = designPage(() => {

  interface iFormData {
    taskName: string,
  }

  const state = reactive({
    formData: {
      taskName: '简历:前端工程师',
    } as iFormData
  });

  const edit = (() => {
    const innerState = reactive({
      editData: null as null | iFormData,
    });
    let dfd: DFD<iFormData> | null = null;
    const open = () => {
      innerState.editData = JSON.parse(JSON.stringify(state.formData));
      dfd = defer<iFormData>();
      dfd.promise.then(val => {
        state.formData = val;
      });
    };
    const cancel = () => {
      dfd!.reject();
      innerState.editData = null;
      dfd = null;
    };
    const confirm = () => {
      dfd!.resolve(innerState.editData!);
      innerState.editData = null;
      dfd = null;
    };
    const renderEdit = (notEditContent: any) => {
      return !innerState.editData ? notEditContent : <>
        <input type="text" value={innerState.editData.taskName} onInput={(e: any) => innerState.editData!.taskName = e.target.value}/>
      </>;
    };
    const renderButton = (externals: any) => {
      return !innerState.editData ? <>
        <button onClick={open}>编辑</button>
        {externals}

          <button onClick={() => alert('transfer')}>转交</button>
        </>)}
      </div>
    </div>
  );
});

Hooks钩子(拦截器)

  • editor有很多内置的钩子函数,用于监听(拦截)各种行为,比如监听节点的点击事件:
editor.hooks.onClickNode.use(({ node }) => {
    console.log('click node', node);
});
  • 钩子函数可以阻止,在添加的拦截函数中抛出异常或者返回Promise.reject()就可以阻止行为。比如添加节点的时候限制只能有一个开始(结束)节点的控制行为:
hooks.onAddNode.use(async ({ node }) => {
if (node.shape == START_NODE) {
  if (!config.onlyOneStartNode) {return; }
  const { cells } = await methods.getGraphData();
  if (!!cells.find(i => i.shape === START_NODE && i.id !== node.id)) {
    alert('只能存在一个开始节点!');
    return Promise.reject('only one start node!');
  }
} else if (node.shape == END_NODE) {
  if (!config.onlyOneEndNode) {return; }
  const { cells } = await methods.getGraphData();
  if (!!cells.find(i => i.shape === END_NODE && i.id !== node.id)) {
    alert('只能存在一个结束节点!');
    return Promise.reject('only one end node!');
  }
}
});

所有可用的Hook钩子

export function useFlowEditorHooks() {

  const hooks = {
    onMouseupCanvas: createHooks<(e: MouseEvent) => void>(),                                // 点击画布动作
    onGraphLoaded: createHooks<(module: iGraphModule) => void>(),                           // Graph模块加载完毕
    onGraphReady: createHooks<(module: iGraphModule) => void>(),                            // graph初始化准备完毕触发动作,onGraphLoaded执行完毕之后就会执行这个动作
    onFlowMounted: createHooks<() => void>(),                                               // ReactX6Editor组件的mounted动作
    onProcessOperators: createSyncHooks<(operators: iFlowEditorOperatorMeta[]) => void>(),  // 处理操作栏按钮

    /*节点钩子*/
    onClickNode: createHooks<(e: NodeView.PositionEventArgs<any>) => void>(),               // 单击节点
    onDblclickNode: createHooks<(e: NodeView.PositionEventArgs<any>) => void>(),            // 双击节点
    onNodeContextmenu: createHooks<(e: NodeView.PositionEventArgs<any>) => void>(),         // 右击节点触发动作
    onAddNode: createHooks<(e: { node: Node, cell: Cell, index: number }) => void>(),       // 添加节点钩子
    onDeleteNode: createHooks<(e: { node: Node, cell: Cell, index: number }) => void>(),    // 删除节点钩子

    /*连接线钩子*/
    onClickEdge: createHooks<(e: EdgeView.PositionEventArgs<any>) => void>(),               // 单击连接线
    onDblclickEdge: createHooks<(e: EdgeView.PositionEventArgs<any>) => void>(),            // 双击连接线
    onEdgeContextmenu: createHooks<(e: EdgeView.PositionEventArgs<any>) => void>(),         // 右击边触发动作
    onVertexContextmenu: createHooks<(e: EdgeView.PositionEventArgs<any>) => void>(),       // 右击拐点触发动作
    onAddEdge: createHooks<(e: { edge: Edge, cell: Cell, index: number }) => void>(),       // 添加连接线钩子
    onDeleteEdge: createHooks<(e: { edge: Edge, cell: Cell, index: number }) => void>(),    // 删除连接线钩子
    onConnectedEdge: createHooks<(e: EdgeView.EventArgs["edge:connected"]) => void>(),      // 连接线连接节点钩子

    /*画布钩子*/
    onBlankContextmenu: createHooks<(e: CellView.PositionEventArgs) => void>(),             // 右击拐点触发动作

    /*其他*/
    onCreateContextmenu: createHooks<(e: { edge?: Edge, node?: Node, view?: View, type: eCreateContextmenuType | keyof typeof eCreateContextmenuType, options: iFlowContextmenuOption[], pos: { x: number, y: number } }) => void>(),
  };

  return hooks;
}

自定义右击菜单

  editor.hooks.onCreateContextmenu.use(({ options, edge, node, type }) => {
    switch (type) {
      case 'node':
        options.push({
          label: '自定义node选项',
          icon: 'data',
          handler: () => alert('自定义node选项')
        });
        options.push({
          label: '自定义node选项2',
          icon: () => <i className="iconfont icon-pay_zhifubao" style={{ padding: '0 4px' }}/>,
          handler: () => alert('自定义node选项2')
        });
        return;
    }
  });

自定义操作栏按钮

  const editor = useFlowEditor({
    onlyOneStartNode: true,
    operators: [
      {
        label: '选项一',
        icon: () => (<i className="iconfont icon-pay_wechat" style={{ height: '27px', display: 'inline-flex', alignItems: 'center', justifyContent: 'center' }}/>),
        handler: () => console.log('option 1...')
      }
    ]
  });

可用函数methods

  • useFlowEditor创建的对象有许多可用函数,使用示例如下所示:
// 获取x6创建的graph对象
const { graph } = await editor.getGraph();
// 获取所有的cell
const cells = graph.getSelectedCells();
  • 所有可用函数如下所示
函数名称类型说明
getGraph()=>Promise异步获取graph实例对象,因为是按需加载antv/x6以及需要等待Editor挂载,所以graph初始化是一个异步的过程
update(data:iFlowData)=>Promise更新数据
getGraphData()=><{ cells: iFlowMetaData[] }>从graph中解析json数据
deleteSelection()=>Promise)删除选中节点
undo()=>:Promise撤销
redo()=>:Promise重做
undoAndClearRedo()=>Promise,撤回,并且清空重做列表
setFrozen(frozen?:boolean)=>Promise冻结

createFlowEditorUser

  • 可以通过函数createFlowEditorUser自定义默认配置的组合函数,比如useFlowEditor的源码如下所示
export const useFlowEditor = createFlowEditorUser({
  height: '100%',
  width: '100%',
  processGraphConfig: ({ graphConfig, module, config }) => {
    return Object.assign({}, {
      background: { color: '#fff' },        // 默认背景色为白色
      grid: {                               // 默认开启网格

        visible: true,
      },

        allowLoop: false,
        allowEdge: false,
        highlight: true,
        createEdge() {
          return new module.Shape.Edge({
            shape: 'flow-edge',
            ...createDefaultEdge(config)
          });
        },
      },
      panning: true,                        // 拖拽画布移动所有节点
      resizing: true,                       // 节点选中之后可以调整大小
      rotating: true,                       // 节点选中之后可以旋转

    } as X6GraphConfig, graphConfig);
  },

  cannotDeleteStartNode: false,
  cannotDeleteEndNode: false,
});

操作说明

节点连接桩

  • 鼠标进入节点会显示节点的连接桩,拖拽连接桩到另一个节点或者另一个节点的连接桩,会创建一条连接线;
  • 点击节选会使得节点处于选中状态,处于选中状态的节点不会显示连接桩;但是此时可以拖拽调整节点大小。
  • 默认情况下,一个节点连接到另一个节点,不会保留连接线的开始节点连接桩以及目标节点的连接桩。右击节点,启用【保留连接桩】,此时从该节点连接的连线在创建的时候就不会自动去掉连接桩,同理如果这个节点为连接线的目标节点也是一样。如果需要保留连接线的连接桩,需要右击节点勾选保留连接桩;

连接线拐点

  • 默认情况下拐点的功能,是单击(双击)拖拽连接线添加拐点,或者移动拐点,双击存在的拐点删除拐点。
  • 为了支持业务需求,目前默认禁用了这些行为。单击拖拽连接线空白处不会添加拐点,双击拐点不会删除拐点。而是右击连接线,在右击的位置添加拐点,右击拐点选择删除拐点。
  • 单击连接线的时候会选中连接线,之后可以删除。同时预留双击连接线的功能用来处理更多业务需求;

可交互的React节点

  • 默认情况下,选中节点之后,选中框会挡住节点。此时如果节点是自定义React渲染的节点,那么选中框会挡住React节点的内容(按钮、输入框等等)的点击动作。
  • 目前为了优化这个逻辑,监听了选中的动作。当单选的时候,通过css选择器的方式,设置选中框的div的css属性pointer-eventsnone以避免挡住节点内容的操作;多选的时候则不做处理,允许选择框挡住节点(方便拖拽整体移动节点);

快捷键

多选

在画布上摁住shift可以框选多个节点,框选完毕之后,可以摁住ctrl或者meta键选中某个节点,以实现额外添加或者取消选中节点的功能;
