基于Antd4 和React-hooks的项目开发

本文主要是介绍基于Antd4 和React-hooks的项目开发，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

基于Antd4 和React-hooks的项目开发

https://github.com/dL-hx/react-cnode

项目依赖使用

• react 16.13
• react-redux 7.x
• react-router-dom 5.x
• redux 4.x
• antd 4
• axios
• moment 2.24 (日期格式化)
• qs

配置按需加载

https://3x.ant.design/docs/react/use-with-create-react-app-cn#%E9%AB%98%E7%BA%A7%E9%85%8D%E7%BD%AE

$ yarn add react-app-rewired customize-cra

高级配置#

$ yarn add react-app-rewired customize-cra
/* package.json */
"scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test",
+   "test": "react-app-rewired test",
}

module.exports = function override(config, env) {// do stuff with the webpack config...return config;
};

使用 babel-plugin-import#

$ yarn add babel-plugin-import
+ const { override, fixBabelImports } = require('customize-cra');- module.exports = function override(config, env) {
-   // do stuff with the webpack config...
-   return config;
- };
+ module.exports = override(
+   fixBabelImports('import', {
+     libraryName: 'antd',
+     libraryDirectory: 'es',
+     style: 'css',
+   }),
+ );

  // src/App.jsimport React, { Component } from 'react';
- import Button from 'antd/es/button';
+ import { Button } from 'antd';import './App.css';class App extends Component {render() {return (<div className="App"><Button type="primary">Button</Button></div>);}}export default App;

自定义主题#

$ npm install less@3.9.0 less-loader@4.1.0 --save-dev
- const { override, fixBabelImports } = require('customize-cra');
+ const { override, fixBabelImports, addLessLoader } = require('customize-cra');module.exports = override(fixBabelImports('import', {libraryName: 'antd',libraryDirectory: 'es',
-   style: 'css',
+   style: true,}),
+ addLessLoader({
+   javascriptEnabled: true,
+   modifyVars: { '@primary-color': '#1DA57A' },
+ }),
);

* react hooks 中的state使用

+   import { useSelector } from 'react-redux'
+   console.log(useSelector(state => state));
+   console.log(useSelector(state => state.topic));+ // 获取search
+ import qs from 'qs';
+ const { search } = useLocation();
+ const { tab } = qs.parse(search.substr(1))

获取地址栏id参数

import { useParams } from 'react-router-dom';
let { id } = useParams()

获取history对象,返回上一页

import { useHistory } from 'react-router-dom';let history = useHistory()
afterClose={()=>{history.goBack()
}}

配置页面整体布局和响应式处理方案

配置通用头部+Footer底部
组件基于bootstrap的响应式处理

列表实现

获取异步数据

如何获取异步数据,hooks写法与之前有何不同
数据和reducer进行关联

let getData = useTopicsList()
let {search} = useLocation()
let {tab, page} = qs.parse(search.substr(1));
useEffect(() => {// 调接口
getData(tab, page)
}, [tab, page]);
// ....function useTopicsList() {const dispatch = useDispatch()return function (tab = "dev", page = 1, limit = 20, mdrender = false) {dispatch({type: 'topics_loading',})http.get(`/topics?tab=${tab}&page=${page}&limit=${limit}&mdrender=${mdrender}`).then(res => {dispatch({// 存入state的数据type: 'topics_loadover',data: res.data.data})})}
}

moment转日期格式

dayjs处理时间
https://dayjs.fenxianglu.cn/category/display.html#%E6%A0%BC%E5%BC%8F%E5%8C%96

import dayjs from 'dayjs';
var relativeTime = require('dayjs/plugin/relativeTime')
dayjs.extend(relativeTime)
require('dayjs/locale/zh-cn')
dayjs.locale('zh-cn'){/* 日期内容 */}{/* 返回现在到当前实例的相对时间。 */}{dayjs(last_reply_at).fromNow()}

分页

获取分类,点击分页时,修改地址栏参数(关联)
Pagination组件

import React from "react";
import { Pagination } from 'antd'
import { Link, useLocation } from 'react-router-dom'
import qs from 'qs'// 获取分类,点击分页时,修改地址栏参数(关联)
export default function IndexPagination() {// 通过qs获取分类let { search } = useLocation();let { tab = "all", page = 1 } = qs.parse(search.substr(1));return <div className="index-pagination"><PaginationdefaultCurrent={page}defaultPageSize={20}total={1000}showSizeChanger={false}itemRender={(page, type) => {switch (type) {case 'page':return <Link to={`/?tab=${tab}&page=${page}`}>{page}</Link>case 'prev':return <Link to={`/?tab=${tab}&page=${page}`}> {"<"} </Link>case 'next':return <Link to={`/?tab=${tab}&page=${page}`}> {">"}</Link>default:return <Link to={`/?tab=${tab}&page=${page}`}> {"..."}</Link>}}}/></div>
}

详情

封装时间组件

import dayjs from 'dayjs';
var relativeTime = require('dayjs/plugin/relativeTime')
dayjs.extend(relativeTime)
require('dayjs/locale/zh-cn')
dayjs.locale('zh-cn')// 处理时间的组件
export default function FromNow(props){let {date} = propsreturn dayjs(date).fromNow()
}

使用

<FromNow date={create_at}/>
<FromNow date={last_reply_at}/>

评论列表组件

import React from 'react'
import {Avatar, Card, List, Comment} from "antd";
import {UserOutlined} from "@ant-design/icons";
import FromNow from "../../components/FromNow";
import {Link} from "react-router-dom";export default function Replies(props) {let {data=[], loading} = propsreturn <Cardtitle="评论列表"loading={loading}id='replies'><ListdataSource={data}renderItem={(itemData) => {// console.log(itemData)return <List.Item><Commentauthor={<Link to={`/user/${itemData.author.loginname}`}>{itemData.author.loginname}</Link>}avatar={<Avataricon={<UserOutlined/>}src={itemData.author.avatar_url}title={itemData.author.loginname}/>}content={<divdangerouslySetInnerHTML={{__html: itemData.content}}/>}datetime={<time>发布于: <FromNow data={itemData.create_at}/></time>}/></List.Item>}}pagination={{simple: true}}/></Card>
}

引用组件

• <Replies data={data.replies} loading={loading}/>
  

用户详情

<TopicList loading={loading} data={recent_topics} />
