Webpack5入门到原理9：处理字体图标资源

1. 下载字体图标文件

打开阿里巴巴矢量图标库
选择想要的图标添加到购物车，统一下载到本地

2. 添加字体图标资源

src/fonts/iconfont.ttf
src/fonts/iconfont.woff
src/fonts/iconfont.woff2
src/css/iconfont.css/注意字体文件路径需要修改

src/main.js

import { add } from "./math";
import count from "./js/count";
import sum from "./js/sum";
// 引入资源，Webpack才会对其打包
import "./css/iconfont.css";
import "./css/index.css";
import "./less/index.less";
import "./sass/index.sass";
import "./sass/index.scss";
import "./styl/index.styl";console.log(count(2, 1));
console.log(sum(1, 2, 3, 4));

public/index.html

<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8" /><meta http-equiv="X-UA-Compatible" content="IE=edge" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><title>webpack5</title></head><body><h1>Hello Webpack5</h1><div class="box1"></div><div class="box2"></div><div class="box3"></div><div class="box4"></div><div class="box5"></div><!-- 使用字体图标 --><i class="iconfont icon-arrow-down"></i><i class="iconfont icon-ashbin"></i><i class="iconfont icon-browse"></i><script src="../dist/static/js/main.js"></script></body>
</html>

3. 配置

const path = require("path");module.exports = {entry: "./src/main.js",output: {path: path.resolve(__dirname, "dist"),filename: "static/js/main.js", // 将 js 文件输出到 static/js 目录中clean: true, // 自动将上次打包目录资源清空},module: {rules: [{// 用来匹配 .css 结尾的文件test: /\.css$/,// use 数组里面 Loader 执行顺序是从右到左use: ["style-loader", "css-loader"],},{test: /\.less$/,use: ["style-loader", "css-loader", "less-loader"],},{test: /\.s[ac]ss$/,use: ["style-loader", "css-loader", "sass-loader"],},{test: /\.styl$/,use: ["style-loader", "css-loader", "stylus-loader"],},{test: /\.(png|jpe?g|gif|webp)$/,type: "asset",parser: {dataUrlCondition: {maxSize: 10 * 1024, // 小于10kb的图片会被base64处理},},generator: {// 将图片文件输出到 static/imgs 目录中// 将图片文件命名 [hash:8][ext][query]// [hash:8]: hash值取8位// [ext]: 使用之前的文件扩展名// [query]: 添加之前的query参数filename: "static/imgs/[hash:8][ext][query]",},},{test: /\.(ttf|woff2?)$/,type: "asset/resource",generator: {filename: "static/media/[hash:8][ext][query]",},},],},plugins: [],mode: "development",
};

type: "asset/resource"和type: "asset"的区别：

type: "asset/resource" 相当于file-loader, 将文件转化成 Webpack 能识别的资源，其他不做处理

type: "asset" 相当于url-loader, 将文件转化成 Webpack 能识别的资源，同时小于某个大小的资源会处理成 data URI 形式
