question/Edit/index.tsx
import React, { FC } from 'react'
import styles from './index.module.scss'
// import { useParams } from 'react-router-dom'
// import useLoadQuestionData from '../../../hooks/useLoadQuestionData'
const Edit: FC = () => {
// const { id = '' } = useParams()
// const { loading, data } = useLoadQuestionData()
return (
<div className={styles.container}>
<div style={{ backgroundColor: '#fff', height: '40px' }}>Header</div>

</div>
</div>
)
}
export default Edit
question/Edit/index.module.scss
.container {
display: flex;
flex-direction: column;
height: 100vh;
background-color: #f0f2f5;
}
.content-wrapper {
flex: auto;
padding: 12px 0;
}

}
}
.right {
width: 300px;
background-color: #fff;
padding: 0 12px;
}
}
开发问卷组件：Title 和 Input
开发组件 Title
目标：
要点：
- 组件默认参数设置
{ ...QuestionInputDefaultProps, ...props }
Component.ts
import React, { FC } from 'react'
import { Typography, Input } from 'antd'
import { QuestionTitleProps, QuestionInputDefaultProps } from './interface'
const { Paragraph } = Typography
const QuestionTitle: FC<QuestionTitleProps> = (props: QuestionTitleProps) => {
const { title = '', placeholder = '' } = {
...QuestionInputDefaultProps,
...props,
}
return (
<div>
<Paragraph strong>{title}</Paragraph>
<div>
<Input placeholder={placeholder}></Input>
</div>
</div>
)
}
export default QuestionTitle
interface.ts
export type QuestionTitleProps = {
title?: string
placeholder?: string
}
export const QuestionInputDefaultProps: QuestionTitleProps = {
title: '输入框标题',
placeholder: '请输入内容',
}
开发组件 Input
目标：
要点：
- Input标题样式函数设计
genFontSize
Component.ts
import React, { FC } from 'react'
import { Typography } from 'antd'
import { QuestionTitleProps, defaultQuestionTitleProps } from './interface'
const { Title } = Typography
const QuestionTitle: FC<QuestionTitleProps> = (props: QuestionTitleProps) => {
const {
text = '',
level = 1,
isCenter = false,
} = { ...defaultQuestionTitleProps, ...props }
const genFontSize = (level: number) => {
if (level === 1) return '24px'
if (level === 2) return '20px'
if (level === 3) return '16px'
if (level === 4) return '14px'
if (level === 5) return '12px'
return '24px'
}
return (
<Title
level={level}
style={{
textAlign: isCenter ? 'center' : 'left',
marginBottom: '0px',
fontSize: genFontSize(level),
}}
>
{text}
</Title>
)
}
export default QuestionTitle
interface.ts
export type QuestionTitleProps = {
text?: string
level?: 1 | 2 | 3 | 4 | 5
isCenter?: boolean
}
export const defaultQuestionTitleProps: QuestionTitleProps = {
text: '一行标题',
level: 1,
isCenter: false,
}
画布集成组件测试
目标：
要点：
- 画布元素禁止点击，样式设计
.componet - 标题样式上方多余空距问题处理（见下方）
EditCanvas.tsx
import React, { FC } from 'react'
import styles from './EditCanvas.module.scss'
import QuestionTitle from '../../../component/QuestionComponents/QuestionTitle/Component'
import QuestionInput from '../../../component/QuestionComponents/QuestionInput/Component'
const EditCanvas: FC = () => {
return (
<div className={styles.canvas}>
<div className={styles['component-wrapper']}>
<div className={styles.component}>
<QuestionTitle />
</div>
</div>
<div className={styles['component-wrapper']}>
<div className={styles.component}>
<QuestionInput />
</div>
</div>
</div>
)
}
export default EditCanvas
EidtCanvas.module.scss
.canvas {
min-height: 100%;
background-color: #fff;
overflow: hidden;
}
.component-wrapper {
margin: 12px;
border: 1px solid #fff;
padding: 12px;
border-radius: 3px;
// 新增修复代码（推荐方案）
:global(.ant-typography) {
margin-block-start: 0 !important;
margin-block-end: 0 !important;
}
&:hover {
border: 1px solid #d9d9d9;
}
}
.componet {
pointer-events: none; // 禁止点击
}
问卷数据获取与存储
问卷信息存储在 Redux 中的原因：
组件间需要不断联动，如下所示，段落的选中以及修改，都涉及到相同的数据的访问。因此，建议把问卷信息存储在 Redux 中，便于组件间共享使用。
组件数据结构设计
服务端mock数据：
{
url: '/api/question/:id',
method: 'get',
response() {
return {
errno: 0,
data: {
id: Random.id(),
title: Random.ctitle(),
componentList: [
{
id: Random.id(),
type: 'questionTitle', // 组件类型，不能重复，前后端统一好
title: '这是一个文本组件',
props: {
text: '文本内容',
level1,
isCenter: false
}
},
{
id: Random.id(),
type: 'questionInput',
title: '这是一个输入框组件',
props: {
title: '你的名字',
placeholder: '请输入内容'
}
},
{
id: Random.id(),
type: 'questionInput',
title: '这是一个输入框组件',
props: {
title: '你的电话',
placeholder: '请输入内容'
}
}
],
}
}
}
},
Ajax 加载数据
要点：
- Hook
useLoadQuestionData设计- 问卷信息获取函数
- id 变化，更新问卷信息
- 数据更新后，存储在 Redux 中
useLoadQuestionData.ts
import { useEffect } from 'react'
import { useParams } from 'react-router-dom'
import { useDispatch } from 'react-redux'
import { getQuestionService } from '../services/question'
import { useRequest } from 'ahooks'
import { resetComponentList } from '../store/componentReducer'
function useLoadQuestionData() {
const { id = '' } = useParams()
const dispatch = useDispatch()
// 问卷信息获取函数
const { data, loading, error, run } = useRequest(
async (id: string) => {
const data = await getQuestionService(id)
return data
},
{
manual: true,
}
)
// 数据更新后，存储在 Redux 中
useEffect(() => {
if (!data) return
const { title = '', componentList } = data
if (!componentList || componentList.length === 0) return
const action = resetComponentList({ componentList })
dispatch(action)
}, [data])
// id 变化，更新问卷信息
useEffect(() => {
run(id)
}, [id])
return {
loading,
error,
}
}
export default useLoadQuestionData
Redux 数据存储
要点：
- 设计 componentReducer，定义类型以及切片
- 设计 index，作为各个切片 类型 和 reducer 的统一收口
文件树：
│ ├── store
│ │ ├── componentReducer
│ │ │ └── index.ts
│ │ ├── index.ts
│ │ └── userReducer.ts
componentReducer/index.ts
import { createSlice, PayloadAction } from '@reduxjs/toolkit'
import { ComponentPropsType } from '../../component/QuestionComponents'
export type ComponentInfoType = {
fe_id: string
type: string
title: string
props: ComponentPropsType
}
export type ComponentsStateType = {
componentList: Array<ComponentInfoType>
}
const INIT_STATE: ComponentsStateType = {
componentList: [],
// 其他拓展
}
export const componentsSlice = createSlice({
name: 'component',
initialState: INIT_STATE,
reducers: {
resetComponentList: (
state: ComponentsStateType,
action: PayloadAction<ComponentsStateType>
) => {
return action.payload
},
},
})
export const { resetComponentList } = componentsSlice.actions
export default componentsSlice.reducer
index.ts
import { configureStore } from '@reduxjs/toolkit'
import userReducer, { UserStateType } from './userReducer'
import componentReducer, { ComponentsStateType } from './componentReducer'
export type StateType = {
user: UserStateType
components: ComponentsStateType
}
export default configureStore({
reducer: {
user: userReducer,
components: componentReducer,
// 组件列表
// 问卷信息
},
})
画布显示问卷列表
组件类型设定
要点：
- 整合各组件 prop type
- 整合各组件 配置列表
文件树：
│ │ ├── QuestionComponents
│ │ │ ├── QuestionInput
│ │ │ │ ├── Component.tsx
│ │ │ │ ├── index.ts
│ │ │ │ └── interface.ts
│ │ │ ├── QuestionTitle
│ │ │ │ ├── Component.tsx

│ │ │ └── index.ts
QuestionComponents/index.ts
import QuestionInputConf, { QuestionInputPropsType } from './QuestionInput'
import QuestionTitleConf, { QuestionTitlePropsType } from './QuestionTitle'
// 各个组件的 prop type
export type ComponentPropsType = QuestionInputPropsType & QuestionTitlePropsType
// 组件的配置
export type ComponentConfType = {
title: string
type: string
Component: React.FC<ComponentPropsType>
defaultProps: ComponentPropsType
}
// 全部组件配置的列表
const componentConfList: ComponentConfType[] = [
QuestionInputConf,
QuestionTitleConf,
]
export function getComponentConfByType(type: string) {
return componentConfList.find(c => c.type === type)
}
画布动态显示组件列表
效果：
要点：
- 根据组件类型动态渲染指定组件
- 返回组件函数实现：
getComponent用于根据组件类型返回指定组件
- 返回组件函数实现：
question/Edit/EditCanvas.tsx
import React, { FC } from 'react'
import styles from './EditCanvas.module.scss'
// import QuestionTitle from '../../../component/QuestionComponents/QuestionTitle/Component'
// import QuestionInput from '../../../component/QuestionComponents/QuestionInput/Component'
import { Spin } from 'antd'
import useGetComponentInfo from '../../../hooks/useGetComponentInfo'
import { getComponentConfByType } from '../../../component/QuestionComponents'
import { ComponentInfoType } from '../../../store/componentReducer'
type PropsType = {
loading: boolean
}
function getComponent(componentInfo: ComponentInfoType) {
const { type, props } = componentInfo
const componentConf = getComponentConfByType(type)
if (!componentConf) {
return null
}
const { Component } = componentConf
return <Component {...props} />
}
const EditCanvas: FC<PropsType> = ({ loading }) => {
const { componentList } = useGetComponentInfo()
if (loading) {
return (
<div style={{ textAlign: 'center', padding: '20px' }}>
<Spin />
</div>
)
}
return (
<div className={styles.canvas}>
{componentList.map(c => {
const { fe_id } = c
return (
<div key={fe_id} className={styles['component-wrapper']}>
<div className={styles.component}>{getComponent(c)}</div>
</div>
)
})}
</div>
)
// <div className={styles.canvas}>
// <div className={styles['component-wrapper']}>
// <div className={styles.component}>
// <QuestionTitle />
// </div>
// </div>
// <div className={styles['component-wrapper']}>
// <div className={styles.component}>
// <QuestionInput />
// </div>
// </div>
// </div>
}
export default EditCanvas
点击画布选中组件
效果：
要点：
- 选中画布中组件显示
- 点击画布组件选中，点击空白不选中。
clearSelectedId()和handleClick()实现- 冒泡机制实现
- 组件 selectedId 与 Redux 绑定
- ComponentsStateType 设定 selectedId
useLoadQuestionData设定进入画布时默认选中组件
- 点击画布组件选中，点击空白不选中。
- 处理 Immer 中 draft 为空的问题
EditCanvas.tsx
import React, { FC, MouseEvent } from 'react'
import styles from './EditCanvas.module.scss'
import { useDispatch } from 'react-redux'
import useGetComponentInfo from '../../../hooks/useGetComponentInfo'

}
const { Component } = componentConf
return <Component {...props} />
}
const EditCanvas: FC<PropsType> = ({ loading }) => {
const { componentList, selectedId } = useGetComponentInfo()
const dispatch = useDispatch()
// 点击冒泡机制实现
function handleClick(event: MouseEvent, id: string) {
event.stopPropagation()
dispatch(changeSelectedId(id))
}
if (loading) {
return (
<div style={{ textAlign: 'center', padding: '20px' }}>
<Spin />
</div>
)
}
return (
<div className={styles.canvas}>
{componentList.map(c => {
const { fe_id } = c
// 拼接 class name
const wrapperDefaultClassName = styles['component-wrapper']
const selectedClassName = styles.selected
const wrapperClassName = classNames({
[wrapperDefaultClassName]: true,
[selectedClassName]: fe_id === selectedId,
})
return (
<div
key={fe_id}
className={wrapperClassName}
onClick={e => handleClick(e, fe_id || '')}

}, [data])
fix：immer draft 为空
**问题：**draft打印出来为null，请问是什么原因？
// ... 其他代码保持不变 ...
export const componentsSlice = createSlice({
name: 'component',
initialState: INIT_STATE,
reducers: {
// 错误写法：多层嵌套 produce
changeSelectedId: produce( // 需移除外层 produce
(draft: ComponentsStateType, action: PayloadAction<string>) => {
console.log('payload', action.payload)
console.log(draft) // 此时 draft 为 null
draft.selectedId = action.payload || ''
}
),
},
})
原因：
- Redux Toolkit 已内置 Immer 集成，无需额外使用
produce包装 - 双重 Immer 包装会导致状态代理失效，此时
draft参数无法正确接收 Redux 状态树 - 直接通过
state参数操作即可实现安全的不可变更新
方案：
export const componentsSlice = createSlice({
name: 'component',
initialState: INIT_STATE,
reducers: {
// 正确写法：直接使用 Immer（Redux Toolkit 已内置）
changeSelectedId: (state: ComponentsStateType, action: PayloadAction<string>) => {
console.log('payload', action.payload)
state.selectedId = action.payload || ''
},
// ...其他 reducer 保持不变...
},
})
注意点：
- RTK 从 1.0 版本开始内置 Immer。
- Immer 默认用于
createSlice和createReducer，允许开发者以“可变”的方式更新状态。 - 如果需要，可以通过配置禁用 Immer，但绝大多数情况下，默认启用 Immer 是推荐的做法。
组件库面板
组件分组显示
需求：
要点：
- 组件库配置
- 组件库组件列表渲染显示
- 组件库组件点击框图、鼠标样式设计
思路：
先对组件库进行配置，然后在页面中对应位置进行渲染组件即可。
QuestionComponents/index.ts
import QuestionInputConf, { QuestionInputPropsType } from './QuestionInput'
import QuestionTitleConf, { QuestionTitlePropsType } from './QuestionTitle'
export type ComponentPropsType = QuestionInputPropsType & QuestionTitlePropsType
export type ComponentConfType = {
title: string
type: string
Component: React.FC<ComponentPropsType>
defaultProps: ComponentPropsType
}
const componentConfList: ComponentConfType[] = [
QuestionInputConf,
QuestionTitleConf,
]
// 组件库配置
export const componentConfGroup = [
{
groupId: 'textGroup',
groupName: '文本显示',
components: [QuestionTitleConf],
},
{
groupId: 'inputGroup',
groupName: '用户输入',
components: [QuestionInputConf],
},
]
export function getComponentConfByType(type: string) {
return componentConfList.find(c => c.type === type)
}
ComponentLib.tsx
import React, { FC } from 'react'
import { componentConfGroup } from '../../../component/QuestionComponents'
import { Typography } from 'antd'
import { ComponentConfType } from '../../../component/QuestionComponents'
import styles from './ComponentLib.module.scss'
const { Title } = Typography
function genComponent(c: ComponentConfType) {
const { Component } = c
return (
<div className={styles.wrapper}>
<div className={styles.component}>
<Component />
</div>
</div>
)
}
const Lib: FC = () => {
return (
<>
{componentConfGroup.map((item, index) => {
const { groupId, groupName } = item
return (
<div key={groupId}>
<Title
level={3}
style={{ fontSize: '16px', marginTop: index > 0 ? '20px' : '0' }}
>
{groupName}
</Title>
<div>{item.components.map(c => genComponent(c))}</div>
</div>
)
})}
</>
)
}
export default Lib
ComponentLib.scss
.wrapper {
padding: 12px;
margin-bottom: 12px;
cursor: cursor;
border: 1px solid #fff;
border-radius: 3px;
background-color: #fff;
&:hover {
border-color: #d9d9d9;
}
}
.component {
pointer-events: none; // 屏蔽鼠标
}
No newline at end of file
组件库添加到画布
需求：
要点：
- 组件与画布交互逻辑
- 组件默认插入画布末尾
- 画布中组件选定后，组件插入会在其之后
- 交互逻辑数据实现
ComponentLib组件插入画布位置逻辑实现addComponent通过 selected 判断组件插入画布位置
ComponentLib.tsx
import React, { FC } from 'react'
import { componentConfGroup } from '../../../component/QuestionComponents'
import { Typography } from 'antd'
import { ComponentConfType } from '../../../component/QuestionComponents'
import styles from './ComponentLib.module.scss'
import { useDispatch } from 'react-redux'
import { addComponent } from '../../../store/componentReducer'
import { nanoid } from '@reduxjs/toolkit'
const { Title } = Typography
const Lib: FC = () => {
const dispatch = useDispatch()
function genComponent(c: ComponentConfType) {
const { type, Component } = c
function handleClick(c: ComponentConfType) {
const { title, type, defaultProps } = c
dispatch(
addComponent({
fe_id: nanoid(),
type,
title,
props: defaultProps,
})
)
}
return (
<div key={type} className={styles.wrapper} onClick={() => handleClick(c)}>
<div className={styles.component}>
<Component />
</div>
</div>
)
}
return (
<>
{componentConfGroup.map((item, index) => {
const { groupId, groupName } = item
return (
<div key={groupId}>
<Title
level={3}
style={{ fontSize: '16px', marginTop: index > 0 ? '20px' : '0' }}
>
{groupName}
</Title>
<div>{item.components.map(c => genComponent(c))}</div>
</div>
)
})}
</>
)
}
export default Lib
componentReducer/index.ts
import { createSlice, PayloadAction } from '@reduxjs/toolkit'
import { ComponentPropsType } from '../../component/QuestionComponents'
export type ComponentInfoType = {
fe_id: string
type: string
title: string
props: ComponentPropsType
}
export type ComponentsStateType = {
selectedId: string
componentList: Array<ComponentInfoType>
}
const INIT_STATE: ComponentsStateType = {
selectedId: '',
componentList: [],
// 其他拓展
}
export const componentsSlice = createSlice({
name: 'component',
initialState: INIT_STATE,
reducers: {
......
addComponent: (
draft: ComponentsStateType,
action: PayloadAction<ComponentInfoType>
) => {
const newCompontent = action.payload
const { selectedId, componentList } = draft
const index = componentList.findIndex(c => c.fe_id === selectedId)
if (index < 0) {
draft.componentList.push(newCompontent)
} else {
draft.componentList.splice(index + 1, 0, newCompontent)
}
draft.selectedId = newCompontent.fe_id
},
},
})
export const { resetComponentList, changeSelectedId, addComponent } =
componentsSlice.actions
export default componentsSlice.reducer
注意：fe_id 和 _id 区别
要点：
- _id是服务端的数据，_是因为 mongodb 会为每条数据生成id，这是不重复的，由 _id 表示
- fe_id 是前端用于区分组件是否被选中的标记，用于组件库与画布的交互
QuestionCart.tsx
type PropsType = {
_id: string
title: string
isPublished: boolean
isStar: boolean
answerCount: number
createdAt: string
}
组件属性面板
点击组件显示属性
需求：
要点：
- 构建属性面板
- 构造组件属性模块
PropComponet，用于配制组件属性
│ │ ├── QuestionComponents
│ │ │ ├── QuestionInput
│ │ │ │ ├── Component.tsx
│ │ │ │ ├──+ PropComponent.tsx
│ │ │ │ ├── index.ts
│ │ │ │ └── interface.ts

│ │ │ │ ├── Component.tsx
│ │ │ │ ├──+ PropComponent.tsx
│ │ │ │ ├── index.ts
│ │ │ │ └── interface.ts
│ │ │ └──m index.ts
思路：
- 当我们点击画布中的组件后，更新组件
selectedId - 属性面板通过
useGetComponentInfo获取selectedComponent-
从
selectedComponent中层层解构出组件参数props和参数组件PropComponent，返回
<PropComponent {...props} />传参后的组件即可。
-
构建属性面板
RightPanel.tsx
import React, { FC } from 'react'
import { Tabs } from 'antd'
import { FileTextOutlined, SettingOutlined } from '@ant-design/icons'
import ComponentProp from './componentProp'
const RightPanel: FC = () => {
const tabsItems = [
{
key: 'prop',
label: (
<span>
<FileTextOutlined />
属性
</span>
),
children: <ComponentProp />,
},
{
key: 'setting',
label: (
<span>
<SettingOutlined />
页面设置
</span>
),
children: <div>页面设置</div>,
},
]
return <Tabs defaultActiveKey="prop" items={tabsItems} />
}
export default RightPanel
构造组件属性模块 PropComponet ，用于配制组件属性
question/Edit/ComponentProp.tsx
import React, { FC } from 'react'
import useGetComponentInfo from '../../../hooks/useGetComponentInfo'
import { getComponentConfByType } from '../../../component/QuestionComponents'
const NoProp = () => {
return <div style={{ textAlign: 'center' }}>请先选择组件</div>
}
const ComponentProp: FC = () => {
const { selectedComponent } = useGetComponentInfo()
if (!selectedComponent) return <NoProp />
const { type, props } = selectedComponent
const componentConf = getComponentConfByType(type)
if (!componentConf) return <NoProp />
const { PropComponent } = componentConf
return <PropComponent {...props} />
}
export default ComponentProp
QuestionComponents/index.ts 新增 PropComponent
import QuestionInputConf, { QuestionInputPropsType } from './QuestionInput'
import QuestionTitleConf, { QuestionTitlePropsType } from './QuestionTitle'
import { FC } from 'react'
export type ComponentPropsType = QuestionInputPropsType & QuestionTitlePropsType
// 组件的配置: 新增 PropComponent
export type ComponentConfType = {
title: string
type: string
Component: FC<ComponentPropsType>
PropComponent: FC<ComponentPropsType> // Here
defaultProps: ComponentPropsType
}
const componentConfList: ComponentConfType[] = [
QuestionInputConf,
QuestionTitleConf,
]

组件属性数据同步画布
需求：
要点：
componentProp统一更新组件数据，更新方式传递给PropComponent- Redux 设计
changeComponentProps参数更新函数
思路：
- 用户选择画布组件后，传递
selectedId到Redux中 - 用户更新组件属性面板数值，会通过
onChange事件传递参数到Redux，采用changeComponentProps对画布中组件数据进行修改
Edit/componentProp.tsx
import React, { FC } from 'react'
import useGetComponentInfo from '../../../hooks/useGetComponentInfo'
import {
getComponentConfByType,
ComponentPropsType,
} from '../../../component/QuestionComponents'
import { useDispatch } from 'react-redux'
import { changeComponentProps } from '../../../store/componentReducer'
const NoProp = () => {
return <div style={{ textAlign: 'center' }}>请先选择组件</div>
}
const ComponentProp: FC = () => {
const dispatch = useDispatch()
const { selectedComponent } = useGetComponentInfo()
if (!selectedComponent) return <NoProp />
const { type, props } = selectedComponent
const componentConf = getComponentConfByType(type)
if (!componentConf) return <NoProp />
const { PropComponent } = componentConf
// 组件参数更新：传递组件参数到 Redux 进行更新
function changeProps(newProps: ComponentPropsType) {
if (!selectedComponent) return
dispatch(changeComponentProps({ fe_id: selectedComponent.fe_id, newProps }))
}
return <PropComponent {...props} onChange={changeProps} />
}
export default ComponentProp
store/componentReducer/index.tsx
import { createSlice, PayloadAction } from '@reduxjs/toolkit'
import { ComponentPropsType } from '../../component/QuestionComponents'
......
export const componentsSlice = createSlice({
name: 'component',
initialState: INIT_STATE,
reducers: {
......
changeComponentProps: (
draft: ComponentsStateType,
action: PayloadAction<{ fe_id: string; newProps: ComponentPropsType }>
) => {
const { fe_id, newProps } = action.payload
const component = draft.componentList.find(c => c.fe_id === fe_id)
if (component) {
component.props = {
...component.props,
...newProps,
}
}
},
