基于react18+react-vant+zustand仿微信手机端聊天室ReactChat。
react18-chat 一款使用最新react18.x hooks、zustand搭配react-vant组件库开发的mobile版仿微信界面聊天实例项目。实现了发送图文消息、图片/视频预览、红包/朋友圈等功能。
使用vscode开发工具,整个项目采用react18 hooks函数组件编码开发。
如果对react18 hooks开发自定义弹框组件感兴趣,可以去看看这篇分享文章。
https://www.cnblogs.com/xiaoyan2017/p/17592708.html
整个项目使用到的弹窗组件均是rcpop自定义弹窗组件实现功能,支持多种弹窗类型/动画效果及20+参数配置。
项目中顶部navbar及底部tabbar组件均是基于react18自定义组件实现功能。
在components目录下新建navbar和tabbar组件目录。

使用最新版react-router-dom v6进行路由管理。
/**

*/
import { lazy, Suspense } from 'react'
import { useRoutes, Outlet, Navigate } from 'react-router-dom'
import { Loading } from 'react-vant'
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 Chat = lazy(() => import('@views/chat/chat'))

const Error = lazy(() => import('@views/404'))
// 加载提示
const SpinLoading = () => {
return (
// 延迟加载
const lazyload = children => {
// React 16.6 新增了
}
// 路由鉴权验证
const RouterAuth = ({ children }) => {
const authState = authStore()
return authState.isLogged ? (
children
) : (
)
}
// 路由占位模板(类似vue中router-view)
const RouterLayout = () => {
return (
// useRoutes集中式路由配置
export const routerConfig = [
{
path: '/',
element: lazyload(
children: [
// 首页

以往都是react搭配redux、react-redux进行状态管理,这次则改为使用轻量级zustand,非常灵活小巧的一款react状态管理插件,支持本地持久化存储。使用语法上有些类似vue3状态管理插件Pinia。
/**
* Zustand状态管理,配合persist本地持久化存储
*/
import { create } from 'zustand'
import { persist, createJSONStorage } from 'zustand/middleware'
export const authStore = create(
persist(
(set, get) => ({
isLogged: false,
token: null,
loggedData: (data) => set({isLogged: data.isLogged, token: data.token})
}),
{
name: 'authState',
// name: 'auth-store', // name of the item in the storage (must be unique)
// storage: createJSONStorage(() => sessionStorage), // (optional) by default, 'localStorage' is used
}
)
)
import { authStore } from '@/store/auth'
function auth() {
const authState = authStore()
authState.xxx
...
}
这样会在本地存储有authState记录了。
聊天编辑框支持在光标处插入表情,多行文本输入等功能。
解决了react18 hooks输入框每次输入光标就会跳回到首位的问题。
/**
* 编辑器模板
*/
import { useRef, useState, useEffect, forwardRef, useImperativeHandle } from 'react'
import clsx from 'clsx'
const Editor = forwardRef((props, ref) => {
const {
// 编辑器值
value = '',
// 事件
onClick = () => {},
onFocus = () => {},
onBlur = () => {},
onChange = () => {},
className,
...rest
} = props
const \[editorText, setEditorText\] = useState(value)
const editorRef = useRef(null)
const isChange = useRef(true)
// 记录光标位置
const lastCursor = useRef(null)
// 获取光标最后位置
const getLastCursor = () => {
let sel = window.getSelection()
if(sel && sel.rangeCount > 0) {
return sel.getRangeAt(0)
}
}
const handleInput = () => {
setEditorText(editorRef.current.innerHTML)
lastCursor.current = getLastCursor()
}
// 点击编辑器
const handleClick = () => {
onClick?.()
lastCursor.current = getLastCursor()
}
// 获取焦点
const handleFocus = () => {
isChange.current = false
onFocus?.()
lastCursor.current = getLastCursor()
}
// 失去焦点
const handleBlur = () => {
isChange.current = true
onBlur?.()
}
// 删除内容
const handleDel = () => {
let range
let sel = window.getSelection()
if(lastCursor.current) {
sel.removeAllRanges()
sel.addRange(lastCursor.current)
}
range = getLastCursor()
range.collapse(false)
document.execCommand('delete')
// 删除表情时禁止输入法
setTimeout(() => { editorRef.current.blur() }, 0);
}
// 清空编辑器
const handleClear = () => {
editorRef.current.innerHTML = ''
}
// 光标处插入内容 @param html 需要插入的内容
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()
// ##注意:判断最后光标位置
if(lastCursor.current) {
sel.removeAllRanges()
sel.addRange(lastCursor.current)
}
if(sel.getRangeAt && sel.rangeCount) {
range = sel.getRangeAt(0)
range.deleteContents()
