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' | |

// 引入路由页面 | |
import Login from '@views/auth/login' | |

// 加载提醒 | |
const SpinLoading = () => { | |

// 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 = [ | |

}, | |
// 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()} |
