安装html-webpack-plugin
npm install --save-dev html-webpack-plugin
在webpack.config.js中配置html-webpack-plugin
const path = require('path');
const VueLoaderPlugin = require('vue-loader/lib/plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
mode: 'development',
entry: './src/index.js',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist')
},
module: {
rules: [
// ... 其它规则
{
test: /\.vue$/,
loader: 'vue-loader'
},
// 它会应用到普通的 `.css` 文件
// 以及 `.vue` 文件中的 `<style>` 块
{
test: /\.css$/,
use: [
'vue-style-loader',
'css-loader'
]
},
{
test: /\.js$/,
loader: 'babel-loader'
}
]
},
plugins: [
// 请确保引入这个插件！
new VueLoaderPlugin(),
new HtmlWebpackPlugin({
filename: 'index.html',
template: 'index.html',
inject: true
})
],
resolve:{
extensions:['.vue','.js'],
alias:{
'vue$': 'vue/dist/vue.esm.js'
}
}
}执行npm run start，生成dist目录
index.html原文件：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<div id = "root">
</div>
</body>
</html>dist下目录的index.html文件：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<div id = "root">
</div>
<script type="text/javascript" src="main.js"></script></body>
</html>
html-webpack-plugin生成了index.html文件，并将生成的js插入进去
安装webpack-dev-server
npm install --save-dev webpack-dev-server
在webpack.config.json文件中添加devServer字段配置webpack-dev-server：
const path = require('path');
const VueLoaderPlugin = require('vue-loader/lib/plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
mode: 'development',
entry: './src/index.js',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist')
},
module: {
rules: [
// ... 其它规则
{
test: /\.vue$/,
loader: 'vue-loader'
},
// 它会应用到普通的 `.css` 文件
// 以及 `.vue` 文件中的 `<style>` 块
{
test: /\.css$/,
use: [
'vue-style-loader',
'css-loader'
]
},
{
test: /\.js$/,
loader: 'babel-loader'
}
]
},
plugins: [
// 请确保引入这个插件！
new VueLoaderPlugin(),
new HtmlWebpackPlugin({
filename: 'index.html',
template: 'index.html',
inject: true
})
],
resolve:{
extensions:['.vue','.js'],
alias:{
'vue$': 'vue/dist/vue.esm.js'
}
},
devServer:{
open: true,
host: 'localhost',
port: 8081,
inline: true
}
}在package.json中添加dev命令：
{
"name": "webpacktest",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"dev": "webpack-dev-server",
