自动清空上次打包资源

1. 配置

js
const path = require("path");

module.exports = {
  entry: "./src/main.js",
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "static/js/main.js",
    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: 40 * 1024, // 小于40kb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]",
        },
      },
    ],
  },
  plugins: [],
  mode: "development",
};

2. 运行指令

npx webpack
