# 修改输出资源的名称和路径
|
|
|
|
## 1. 配置
|
|
|
|
```js{7,37-44}
|
|
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
|
|
},
|
|
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]",
|
|
},
|
|
},
|
|
],
|
|
},
|
|
plugins: [],
|
|
mode: "development",
|
|
};
|
|
```
|
|
|
|
## 2. 修改 index.html
|
|
|
|
```html{17}
|
|
<!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>
|
|
<!-- 修改 js 资源路径 -->
|
|
<script src="../dist/static/js/main.js"></script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
## 3. 运行指令
|
|
|
|
```:no-line-numbers
|
|
npx webpack
|
|
```
|
|
|
|
- 此时输出文件目录：
|
|
|
|
（注意：需要将上次打包生成的文件清空，再重新打包才有效果）
|
|
|
|
```
|
|
├── dist
|
|
└── static
|
|
├── imgs
|
|
│ └── 7003350e.png
|
|
└── js
|
|
└── main.js
|
|
```
