1. Download the iconfont font package from the website

2. Build CSS files according to the prompts in the font file package

3. Import HTML file test

[this step is omitted, and there are cases in the font package]

Configure man.js

//import the example
import './css/index.css';

@font-face {

  src: url('./icon/iconfont.ttf?t=1650505701581') format('truetype');
.iconfont {
  font-family: "iconfont" !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;

	height: 100px;
	width: 100px;
	/* display: block; */

	font-size: 150px;	

Project initialization

Module download is not cumbersome here

Key: Type: ‘JavaScript/auto’// you must specify the type. Although you don’t know what, it seems that you must specify the type before which version to display that the loading is normal. If you know, please tell us the specific reasons in the comment area below.

No type specified: ‘JavaScript/auto’

webpack.config..js file configuration [complete solution]

const {resolve} = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
			{test:/\.css$/, use:['style-loader','css-loader']},//css
			// {exclude: /\.(css|js|html)$/, //Exclude the packaging of other resources (in addition to html js css resources unexpected resources) this static packaging font file
			// loader:'file-loader'
			// },
 //{test:/\.(png|woff|woff2|svg|ttf|eot)$/, use:'url-loader?esModule=false&limit=10*1024&name=[hash:8]-[name].[ext]' ,type: 'javascript/auto'},
			options: {
				limit: 10*1024,  //This should be large enough so that all the font icons are packed into the css
				name:"[hash:8]-[name]. [ext]"
			// type: 'javascript/auto' // must specify type
		new HtmlWebpackPlugin({

Start the virtual server with NPM run dev

Enter http://localhost:3000 in the browser address and the iconfont font file of the page is displayed normally
