# 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](https://www.iconfont.cn/)
|
||
|
||
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
|
||
|
||
```js{5}
|
||
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
|
||
|
||
```html{16-19}
|
||
<!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
|
||
|
||
```js{47-53}
|
||
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
|
||
|
||
```:no-line-numbers
|
||
npx webpack
|
||
```
|
||
|
||
打开 index.html 页面查看效果
