在这个示例中,我们创建了一个包含两个节点和一条边的简单流程图。ReactFlow 组件用于渲染流程图,MiniMap、Controls 和Background 是react-flow-renderer 提供的附加组件,分别用于显示小地图、控制按钮和背景。 4. 进一步学习资源和文档链接 react-flow-renderer GitHub 仓库:包含库的源代码、示例和更新日志。 react-flo...
import { MarkerType } from 'react-flow-renderer'; export const nodes=[ { id:'1',//id必须type: 'input',//类型: input开始 default默认 output结束 区别在于连接点不一样data: {//额外的数据label: (//节点名称<>Welcome toReact Flow! </>),//value: 5, ... // 可以将其他数据放入}, pos...
import {useStoreState,useStoreActions}from'react-flow-renderer'; 通常情况下可以直接使用它们来获取 nodes、edges 但如果页面上同时存在多个ReactFlow,或者需要在ReactFlow外部操作画布数据,就需要使用ReactFlowProvider将整个画布包起来 于是整个流程图的入口文件 index.jsx 是这样的: //index.jsximport React, { us...

exportdefaultconnect((state) =>({elements: state}))(EditorReactFlow); Also am I supposed to see the internal store of react-flow-renderer in the redux devtools? I can only see my own app's one, so I presume not? Edit: Currently what I dispatch are Elements from t...
