致读者：探索 CSS 工程化之路 👋

前端开发者们，

今天我们将深入探讨 CSS 工程化实践，学习如何在大型项目中管理 CSS。

工程化配置 🚀

项目结构

src/├── styles/│   ├── base/│   │   ├── _reset.scss│   │   ├── _typography.scss│   │   └── _variables.scss│   ├── components/│   │   ├── _button.scss│   │   ├── _card.scss│   │   └── _form.scss│   ├── layouts/│   │   ├── _grid.scss│   │   ├── _header.scss│   │   └── _footer.scss│   ├── utils/│   │   ├── _mixins.scss│   │   └── _functions.scss│   └── main.scss

构建配置

// webpack.config.js
module.exports = {module: {rules: [{test: /\.scss$/,use: [MiniCssExtractPlugin.loader,{loader: 'css-loader',options: {modules: true,importLoaders: 2}},'postcss-loader','sass-loader']}]},plugins: [new MiniCssExtractPlugin({filename: '[name].[contenthash].css'}),new PurgeCSSPlugin({paths: glob.sync(`${PATHS.src}/**/*`, { nodir: true })})]
};

模块化管理 🎯

CSS Modules

// Button.module.scss
.button {padding: 0.5em 1em;border-radius: 4px;&.primary {background: var(--primary-color);color: white;}&.secondary {background: var(--secondary-color);color: white;}
}// 使用
import styles from './Button.module.scss';const Button = () => (<button className={styles.button}>Click me</button>
);

样式组织

// _variables.scss
:root {// 颜色系统--primary-color: #007bff;--secondary-color: #6c757d;--success-color: #28a745;// 间距系统--spacing-unit: 8px;--spacing-small: calc(var(--spacing-unit) * 1);--spacing-medium: calc(var(--spacing-unit) * 2);--spacing-large: calc(var(--spacing-unit) * 3);// 字体系统--font-family-base: system-ui, -apple-system, sans-serif;--font-size-base: 16px;--line-height-base: 1.5;
}// _mixins.scss
@mixin responsive($breakpoint) {@if $breakpoint == tablet {@media (min-width: 768px) { @content; }} @else if $breakpoint == desktop {@media (min-width: 1024px) { @content; }}
}@mixin flex-center {display: flex;justify-content: center;align-items: center;
}

质量控制 💫

Stylelint 配置

// .stylelintrc.js
module.exports = {extends: ['stylelint-config-standard','stylelint-config-prettier'],plugins: ['stylelint-scss','stylelint-order'],rules: {'order/properties-alphabetical-order': true,'at-rule-no-unknown': null,'scss/at-rule-no-unknown': true,'selector-class-pattern': '^[a-z][a-zA-Z0-9]+$','max-nesting-depth': 3}
};

Git Hooks

// package.json
{"husky": {"hooks": {"pre-commit": "lint-staged"}},"lint-staged": {"*.scss": ["stylelint --fix","prettier --write"]}
}
