处理字体图标资源

1. 下载字体图标文件

  1. 打开阿里巴巴矢量图标库open in new window

  2. 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));

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：

  1. 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
  2. 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

4. 运行指令

npx webpack

打开 index.html 页面查看效果
