1、项目搭建

1、创建项目

1、该项目使用的是ts创建的所以需要加上--template typescript
- create-react-app kiki_ts_react_music --template typescript
2、整理项目结构删除一些自己用不到的文件

1.2 配置项目

1.2.1 更换icon

在这里插入图片描述

1.2.2 更换项目名称

在index.html文件里面

在这里插入图片描述

1.2.1 配置项目别名

1、npm i -D @craco/craco
2、在根文件创建 craco.config.ts

const path = require("path");
const CracoLessPlugin = require("craco-less");// path.resolve返回当前文件的绝对路径 拼接+dir
const resolve = (dir) => path.resolve(__dirname, dir);
module.exports = {plugins: [{ plugin: CracoLessPlugin }],webpack: {alias: {"@": resolve("src"),},},
};

3、修改tsconfig.json

    "baseUrl": ".","paths": {"@/*": ["src/*"]}

4、修改 package.json

  "scripts": {"start": "craco start","build": "craco build","test": "craco test","eject": "react-scripts eject"},

1.3 代码规范

1.3.1 集成editorconfig配置

EditorConfig 有助于为不同 IDE 编辑器上处理同一项目的多个开发人员维护一致的编码风格。

1、在根目录下创建.editorconfig文件

# http://editorconfig.orgroot = true[*] # 表示所有文件适用
charset = utf-8 # 设置文件字符集为 utf-8
indent_style = space # 缩进风格（tab | space）
indent_size = 2 # 缩进大小
end_of_line = lf # 控制换行类型(lf | cr | crlf)
trim_trailing_whitespace = true # 去除行尾的任意空白字符
insert_final_newline = true # 始终在文件末尾插入一个新行[*.md] # 表示仅 md 文件适用以下规则
max_line_length = off
trim_trailing_whitespace = false

**同时需要安装插件 **EditorConfig for VS Code

1.3.2 使用prettier工具

Prettier 是一款强大的代码格式化工具，支持 JavaScript、TypeScript、CSS、SCSS、Less、JSX、Angular、Vue、GraphQL、JSON、Markdown 等语言，基本上前端能用到的文件格式它都可以搞定，是当下最流行的代码格式化工具。

在这里插入图片描述

1.安装prettier

npm install prettier -D
2、配置.prettierrc文件：在根目录下创建该文件

{"useTabs": false,"tabWidth": 2,"printWidth": 80,"singleQuote": true,"trailingComma": "none","semi": false
}

3、创建.prettierignore忽略文件 在根目录下

/dist/*
.local
.output.js
/node_modules/****/*.svg
**/*.sh/public/*

4、在package.json中配置一个scripts：

    "prettier": "prettier --write ."

执行 npm run prettier就会将项目全部按照prettier的配置进行格式化

1.4 项目结构

1.5 对css进行重置

1、下载normalize.css
cnpm install normalize.css
在index.tsx里面引入import 'normalize.css'
2、使用less
cnpm install craco-less

const path = require('path')
const CracoLessPlugin = require('craco-less')const resolve = (dir) => path.resolve(__dirname, dir)
module.exports = {plugins: [{ plugin: CracoLessPlugin }],webpack: {alias: {'@': resolve('src')}}
}

在这里插入图片描述

3、配置自定义的css

最后都在index.jsx中引入

import 'normalize.css'
import '@/assets/css/index.less'

1.6 注入router

npm install react-router-dom

在tsx中使用到dom的页面都需要引入import React from 'react'
router/index.tsx

import React from 'react'
import type { RouteObject } from 'react-router-dom'
import Discover from '@/views/discover'
import Mime from '@/views/mime'const routes: RouteObject[] = [{ path: '/', element: <Mime /> },{ path: '/discover', element: <Discover /> }
]export default routes

index.tsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from '@/App'
import { BrowserRouter } from 'react-router-dom'
import 'normalize.css'
import '@/assets/css/index.less'const root = ReactDOM.createRoot(document.getElementById('root') as HTMLElement)
root.render(<BrowserRouter><App /></BrowserRouter>
)

index.tsx

import React, { Suspense } from 'react'
import { Link, useRoutes } from 'react-router-dom'
import routes from './router'function App() {return (<div className="App"><header className="App-header"><h1>hahah</h1><Link to="/discover">发现音乐</Link><Suspense fallback="正在加载">{useRoutes(routes)}</Suspense></header></div>)
}export default App

1.7 定义TS组件的规范

import React, { memo } from 'react'
import type { ReactNode } from 'react'// 定义传进来的props类型
interface IProps {// 在之前的版本props默认会有children是插槽 在后来取消了得自己写children?: ReactNodename?: stringage?: number
}const Download: React.FC<IProps> = (props) => {return (<div>{props.children}<h1>{props.age}</h1><h1>{props.name}</h1></div>)
}export default memo(Download)

import React, { Suspense } from 'react'
import { Link, useRoutes } from 'react-router-dom'
import routes from './router'
import Download from './views/download'function App() {return (<div className="App"><header className="App-header"><h1>hahah</h1><Link to="/discover">发现音乐</Link><Download name="kiki"><h1>我是downLoad的插槽</h1></Download><Suspense fallback="正在加载">{useRoutes(routes)}</Suspense></header></div>)
}export default App

1.8 创建代码片段

首选项=>设置代码片段=>react-ts
在这里插入图片描述

生成代码片段的网站
https://snippet-generator.app/?description=&tabtrigger=&snippet=&mode=vscode
在这里插入图片描述

import React, { memo } from 'react'
import type { FC, ReactNode } from 'react'interface IProps {children?: ReactNode
}const Template: FC<IProps> = () => {return <div>Template</div>
}export default memo(Template)

1.9 二级路由和懒加载

discover页面

import React, { memo, Suspense } from 'react'
import type { FC, ReactNode } from 'react'
import { Outlet, Link } from 'react-router-dom'interface IProps {children?: ReactNode
}const Discover: FC<IProps> = () => {return (<div><div><Link to="/discover/recommend">推荐</Link><Link to="/discover/ranking">排行榜</Link><Link to="/discover/songs">歌单</Link><Link to="/discover/djradio">主播电台</Link><Link to="/discover/artist">歌手</Link><Link to="/discover/album">新碟上架</Link></div>{/* 二级路由也可以用suspense */}<Suspense fallback="正在加载"><Outlet /></Suspense></div>)
}export default memo(Discover)

App.jsx

import React, { Suspense } from 'react'
import { Link, useRoutes } from 'react-router-dom'
import routes from './router'
import Download from './views/download'function App() {return (<div className="App"><div className="nav"><Link to="/discover">发现音乐</Link><Link to="/mine">我的音乐</Link><Link to="/focus">关注</Link><Link to="/download">下载客户端</Link></div><Suspense fallback="正在加载">{useRoutes(routes)}</Suspense><div className="main"></div></div>)
}export default App

1.10 redux-reduxtk

cnpm install @reduxjs/toolkit react-redux

index.tsx 提供Provide

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from '@/App'
import { BrowserRouter } from 'react-router-dom'
import { Provider } from 'react-redux'
import 'normalize.css'
import '@/assets/css/index.less'
import store from './store'const root = ReactDOM.createRoot(document.getElementById('root') as HTMLElement)
root.render(<Provider store={store}><BrowserRouter><App /></BrowserRouter></Provider>
)

store/index.ts

import { configureStore } from '@reduxjs/toolkit'
import { useSelector, useDispatch, TypedUseSelectorHook } from 'react-redux'
import counterReducer from './modules/counter'const store = configureStore({reducer: {counter: counterReducer}
})// 获取函数的返回类型
type GetStateFnType = typeof store.getState
// 获取函数返回类型的类型
type IRootState = ReturnType<GetStateFnType>
type DispatchType = typeof store.dispatchexport const useAppSelector: TypedUseSelectorHook<IRootState> = useSelector
export const useAppDisPatch: () => DispatchType = useDispatchexport default store

store/count.ts

import { createSlice } from '@reduxjs/toolkit'const counterSlice = createSlice({name: 'counter',initialState: {count: 1,message: 'hello'},reducers: {changeMessageAction(state, { payload }) {state.message = payload}}
})export const { changeMessageAction } = counterSlice.actions
export default counterSlice.reducer

使用的页面

import React, { memo, Suspense } from 'react'
import type { FC, ReactNode } from 'react'
import { Outlet, Link } from 'react-router-dom'
import { useAppDisPatch, useAppSelector } from '@/store'
import { shallowEqual } from 'react-redux'
import { changeMessageAction } from '@/store/modules/counter'interface IProps {children?: ReactNode
}const Discover: FC<IProps> = () => {const { count, message } = useAppSelector((state) => ({count: state.counter.count,message: state.counter.message}),shallowEqual)const dispatch = useAppDisPatch()const changeMessage = (message: string) => {dispatch(changeMessageAction(message))}return (<div><div>{count}=={message}<button onClick={() => changeMessage('修改message')}>修改message</button><Link to="/discover/recommend">推荐</Link><Link to="/discover/ranking">排行榜</Link><Link to="/discover/songs">歌单</Link><Link to="/discover/djradio">主播电台</Link><Link to="/discover/artist">歌手</Link><Link to="/discover/album">新碟上架</Link></div>{/* 二级路由也可以用suspense */}<Suspense fallback="正在加载"><Outlet /></Suspense></div>)
}export default memo(Discover)
