一、项目中css模块化管理

1、css-loader
以下可以使用styles.xxx方式使用class是因为使用css-loader配置了module。

import styles from './index.less'
export const App(){
   
	return <div className={
   styles.xxx}>hello word</div>
}

//webpack配置
{
   
	test:/\.css$/,
	use[{
   
		loader:'css-loader',
		options:{
   
			modules:{
   
				localIndentName:isDevelopment?"[path]_[name]_[local]":"[hash:base64:5]"
			}
		}
	}]
}

开发环境使用路径模块名类名命名方便调试"[path][name][local]“,生产环境使用”[hash:base64:5]"这个命名进行压缩混淆代码减少代码体积。
2、css in js

import styles from './styles.js'
export const App(){
   
	return <div style={
   styles.xxx}>jeelo</div>
}

//.styles.js
const xxx = {
   
	backgroundColor:'red'
}

3、styled-components

import styled from 'styled-components'
const Button = styled.button`background:#ff0`
export const App(){
   
	return <Button >jeelo</Button>
}

tailwind css是原子化的css包,解决一些css的复杂性,类名约定的负担。它主要使用postcss进行css的babelloader转换编译。
控制粒度:bootsrap>tailwind>css
headless ui 是没有样式的。

二、实战一个知乎首页

app.js

import {
    BrowserRouter, Routes, Route } from "react-router-dom";
// pages
import Home from './pages/home'
import CommandList from "./pages/home/tabPages/commandList";

export default function App(params) {
   
    return <BrowserRouter>
        <Routes>
            <Route path="/" element={
   <Home />}>
                <Route path="" element={
   <CommandList />} />
                <Route path="follow" element={
   <div>Follow</div>} />
                <Route path="hot" element={
   <div>Hot</div>} />
                <Route path="zvideo" element={
   <div>ZVideo</div>} />
            </Route>
            <Route path="/xen" element={
   <div>Xen</div>}></Route>
            <Route path="/explore" element={
   <div>Explore</div>}></Route>
            <Route path="/question" element={
   <div>Question</div>}></Route>

        </Routes>
    </BrowserRouter>
};

home.js
这里的navigator导航顶部栏为了滑动滚动条,导航栏依旧留在顶部使用了position:sticky属性,维护一个hide属性在传递给naviagtor组件

// import { Outlet } from "react-router-dom";
import {
    useState } from 'react';
// components
import Navigation from "../../components/navigation";
import Card from '../../components/card';
// pages
import TabPages from './tabPages';
import Creation from './siderPages/creation';
import AdvancedBtns from './siderPages/advancedBtns';
import SelfFuncs from './siderPages/selfFuncs';

export default function Home(params) {
   
    const [hide, setHide] = useState(true);
    const handleChange = (isHide) => setHide(isHide);
    return <div>
        <Navigation className="sticky top-0" hide={
   hide} />
        <div className="mx-auto max-w-7xl w-320 flex m-2">
            <Card className="w-2/3">
                <TabPages onChange={
   handleChange} />
            </Card>
            <div className="w-1/3">
                <Card>
                    <Creation />
                </Card>
                <Card>
                    <AdvancedBtns />
                </Card>
                <Card>
                    <SelfFuncs />
                </Card>
            </div>

        </div>

    </div>
};

navigation导航栏,navigator栏根据滚动传递的hide属性显示不同的顶部栏

import React from 'react'
import {
    Fragment } from 'react';
import {
    NavLink } from 'react-router-dom';
import {
    Menu, Transition } from '@headlessui/react';
import {
    BellIcon } from '@heroicons/react/outline';


const navs = [
    {
    name: "首页", to: "/" },
    {
    name: "会员", to: "/xen" },
    {
    name: "发现", to: "/explore" },
    {
    name: "等你来答", to: "/question" },
]

const tabs = [
    {
    name: "关注", to: "/follow" },
    {
    name: "推荐", to: "/" },
    {
    name: "热榜", to: "/hot" },
    {
    name: "视频", to: "/zvideo" },
]

const Logo = () => <div className='flex'>
    <div className=' flex-shrink-0 flex items-center'>
