一、我的项目介绍
react18 聊天我的项目 ReactChat 基于 vite4+react18+acro design+zustand
等技术架构实现开发仿微信电脑端界面聊天实例。反对图文混排、图片 / 视频预览、红包 / 朋友圈等性能。
二、编码技术
- 编辑器:vscode
- 技术栈:react18+vite4+react-router-dom+zustand+sass
- 组件库:@arco-design/web-react (字节跳动 react 组件库)
- 状态治理:zustand^4.4.1
- 路由治理:react-router-dom^6.15.0
- className 拼合:clsx^2.0.0
- 对话框组件:rdialog (基于 react18 hooks 自定义桌面端弹窗组件)
- 滚动条组件:rscroll (基于 react18 hooks 自定义丑化滚动条)
- 预处理款式:sass^1.66.1
三、我的项目构造目录
整个我的项目采纳 react18 hooks 标准编码开发页面。
react18 自定义弹窗 / 滚动条组件
我的项目中利用到的对话框及滚动条插件均是基于 react18 hooks 自定义组件实现成果。
// 引入弹窗组件
import RDialog, {rdialog} from '@/components/rdialog'
// 组件式调用
<RDialog
visible={confirmVisible}
title="题目信息"
content="对话框内容信息"
closeable
shadeClose={false}
zIndex="2050"
dragOut
maxmin
btns={[{text: '勾销', click: () => setConfirmVisible(false)},
{text: '确定', click: handleInfo}
]}
onClose={()=>setConfirmVisible(false)}
/>
// 函数式调用
rdialog({
title: '题目信息',
content: '对话框内容信息',
closeable: true,
shadeClose: false,
zIndex: 2050,
dragOut: true,
maxmin: true,
btns: [{text: '勾销', click: rdialog.close()},
{text: '确定', click: handleInfo}
]
})
// 引入滚动条组件
import RScroll from '@/components/rscroll'
<RScroll autohide maxHeight={100}>
包裹须要滚动的内容块。。。</RScroll>
main.jsx 入口文件
import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'
import '@arco-design/web-react/dist/css/arco.css'
import './style.scss'
ReactDOM.createRoot(document.getElementById('root')).render(<App />)
App.jsx 模板
import {HashRouter} from 'react-router-dom'
// 引入 useRoutes 集中式路由配置文件
import Router from './router'
function App() {
return (
<>
<HashRouter>
<Router />
</HashRouter>
</>
)
}
export default App
react-router v6 配置
// 路由占位模板(相似 vue 中 router-view)
const RouterLayout = () => {const authState = authStore()
return (<div className="rc__container flexbox flex-alignc flex-justifyc" style={{'--themeSkin': authState.skin}}>
<div className="rc__layout flexbox flex-col">
{/* <div className="rc__layout-header"> 顶部栏 </div> */}
<div className="rc__layout-body flex1 flexbox">
{/* 菜单栏 */}
<Menu />
{/* 两头栏 */}
<Aside />
{/* 主内容区 */}
<div className="rc__layout-main flex1 flexbox flex-col">
{lazyload(<Outlet />) }
</div>
</div>
</div>
</div>
)
}
残缺的配置文件
/**

import {lazy, Suspense} from 'react'
import {useRoutes, Outlet, Navigate} from 'react-router-dom'
import {Spin} from '@arco-design/web-react'
import {authStore} from '@/store/auth'
// 引入路由页面
import Login from '@views/auth/login'
import Register from '@views/auth/register'
const Index = lazy(() => import('@views/index'))
const Contact = lazy(() => import('@views/contact'))
const Uinfo = lazy(() => import('@views/contact/uinfo'))
const NewFriend = lazy(() => import('@views/contact/newfriend'))
const Chat = lazy(() => import('@views/chat/chat'))
const ChatInfo = lazy(() => import('@views/chat/info'))
const RedPacket = lazy(() => import('@views/chat/redpacket'))
const Fzone = lazy(() => import('@views/my/fzone'))
const Favorite = lazy(() => import('@views/my/favorite'))
const Setting = lazy(() => import('@views/my/setting'))
const Error = lazy(() => import('@views/404'))
import Menu from '@/layouts/menu'
import Aside from '@/layouts/aside'
// 加载提醒
const SpinLoading = () => {
return (
<div className="rcLoading">
<Spin size="20" tip='loading...' />
</div>
)
}
// 提早加载
const lazyload = children => {
// React 16.6 新增了 <Suspense> 组件, 让你能够“期待”指标代码加载, 并且能够间接指定一个加载的界面,让它在用户期待的时候显示
// 路由懒加载报错:react-dom.development.js:19055 Uncaught Error: A component suspended while responding to synchronous input.
// 懒加载的模式须要咱们给他加上一层 Loading 的提醒加载组件
return <Suspense fallback={<SpinLoading />}>{children}</Suspense>
}
// 路由鉴权验证
const RouterAuth = ({children}) => {const authState = authStore()
return authState.isLogged ? (children) : (<Navigate to="/login" replace={true} />
)
}
export const routerConfig = [
{
path: '/',
element: <RouterAuth><RouterLayout /></RouterAuth>,
children: [
// 首页
{index: true, element: <Index />},
// 通讯录模块
{path: '/contact', element: <Contact />},
{path: '/uinfo', element: <Uinfo />},
{path: '/newfriend', element: <NewFriend />},
// 聊天模块
{path: '/chat', element: <Chat />},

]
},
// 登录 / 注册
{path: '/login', element: <Login />},
{path: '/register', element: <Register />}
]
const Router = () => useRoutes(routerConfig)
export default Router
zustand 新一代 react18 hooks 状态治理库
反对 react18 hooks 格调的状态治理库 zustand。在用法上有些相似 vue3 pinia 语法。
// NPM
npm install zustand
// Yarn
yarn add zustand
/**
* react18 状态治理库 Zustand
*/
import {create} from 'zustand'
import {persist, createJSONStorage} from 'zustand/middleware'
export const authStore = create(
persist((set, get) => ({
isLogged: false,
token: null,
// 折叠侧边栏
collapse: false,
// 共性换肤
skin: null,
// 登录数据
loggedData: (data) => set({isLogged: data.isLogged, token: data.token}),
setCollapse: (v) => set({collapse: v}),
setSkin: (v) => set({skin: v})
}),
{
name: 'authState',
// name: 'auth-store', // name of the item in the storage (must be unique)
// storage: createJSONStorage(() => sessionStorage), // by default, 'localStorage'
}
)
)
如上图:聊天编辑框反对多行文本、光标处插入表情等性能。
return (
<div
{...rest}
ref={editorRef}
className={clsx('editor', className)}
contentEditable
onClick={handleClick}
onInput={handleInput}
onFocus={handleFocus}
onBlur={handleBlur}
style={{'userSelect': 'text', 'WebkitUserSelect': 'text'}}
/>
)
在光标中央插入指定内容。
const insertHtmlAtCursor = (html) => {
let sel, range
if(!editorRef.current.childNodes.length) {editorRef.current.focus()
}
if(window.getSelection) {
// IE9 及其它浏览器
sel = window.getSelection()
// ## 留神:判断最初光标地位
if(lastCursor.current) {sel.removeAllRanges()
sel.addRange(lastCursor.current)
}
if(sel.getRangeAt && sel.rangeCount) {range = sel.getRangeAt(0)
range.deleteContents()
let el = document.createElement('div')
el.appendChild(html)
var frag = document.createDocumentFragment(), node, lastNode
while ((node = el.firstChild)) {lastNode = frag.appendChild(node)
}
range.insertNode(frag)
if(lastNode) {range = range.cloneRange()
range.setStartAfter(lastNode)
range.collapse(true)
sel.removeAllRanges()
sel.addRange(range)
}
}
} else if(document.selection && document.selection.type != 'Control') {
// IE < 9
document.selection.createRange().pasteHTML(html)
}
// 执行输出操作
handleInput()}
