"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"dev": "webpack --mode development",
"build": "webpack --mode production",
"server": "webpack-dev-server --config webpack.config.js"
},

加载自定义文件
const webpack=require("webpack")
const HtmlWepackPlugin = require('html-webpack-plugin');
const path = require('path');
module.exports={
entry:{
index:path.resolve(__dirname,'src/entry.js')
},
output: {
filename: '[name].[hash].js',
path: path.resolve(__dirname, 'dist'),
publicPath: '/dist/'
},
module: {
rules: [
{test: /\.js$/, use: ['babel-loader']},
{test: /\.css$/, use: ['style-loader', 'css-loader']}
]
},
plugins: [
new HtmlWepackPlugin({
filename: './index.html',
template: './template.html'
})
]
}webpack.config.js
文件目录如下：
