webpack处理字体

参考

url-loader

配置

1.创建本地项目webpack-demo

mkdir webpack-demo
cd webpack-demo

2.在webpack-demo的根目录下创建package.json文件

npm init -y

3. 安装webpack依赖包

npm i webpack webpack-cli webpack-dev-server --save-dev

模块说明：

• webpack
webpack核心

• webpack-cli
webpack的脚手架（启动器）

• webpack-dev-server
  开发环境下用于实时加载依赖

4.修改package.json文件的scripts属性值,进行打包资源的配置

"scripts": {
    "dev": "webpack-dev-server --open --mode development",
    "build": "webpack --mode production"
  },

5.安装相关的loader

npm install  url-loader --save-dev

6.在webpack.config.js中配置

const path = require('path');
// 显示进程的完成进度
var ProgressBarPlugin = require('progress-bar-webpack-plugin');
// 设置进度字体颜色
const chalk = require('chalk');
// 以树图的方式展示打包后的文件
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
// 输出html
const HtmlWebpackPlugin = require('html-webpack-plugin');
// 分离css代码
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
// 清空dist文件夹
const {
  CleanWebpackPlugin
} = require('clean-webpack-plugin');
