以前习惯用gulp+less来开发项目，由于公司项目用的vue开发的，所以学下webpack这个打包工具。以下是我学习时的笔记，希望给在webpack配置过程中遇到麻烦的朋友一丝帮助。
目前只配置了sass,css,js,html,es6,图片编译，字体引入，热加载这几项，简单项目已经够用。
如果深入webpack可以配置很多，原谅我也只是初次配置
1.首先建一个自己的项目文件夹，npm init -y快速生成一个配置文件
2. npm i webpack -D 本地安装webpack
3. npm i webpack-dev-server -g 全局安装webpack-dev-server
4. npm i webpack-dev-server -D 添加到package.json文件里
5.以下是我的package.json，里面的包都是常用的

根目录下的webpack.config.json
// html压缩
var HtmlWebpackPlugin = require('html-webpack-plugin');
// js css分离
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var path = require('path')
var webpack = require('webpack') module.exports = {
// 配置入口文件

build: './src/main.js'
}, // 配置输出路径
output: {
path: path.resolve(__dirname, './dist'),
// publicPath: '/dist/',//指定资源引用目录
filename: '[name].js'
}, // loader模块配置
module: {
loaders: [
// js 文件
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
// css 文件
{
test: /\.css$/,
use: ExtractTextPlugin.extract({

],
// webpack-dev-server 热加载
devServer: {

devtool: '#eval-source-map'
}
.babelrc文件
{
"presets": [
["latest", {
"es2015": { "modules": false }
}]
]
}
index.html移入编译后的文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" type="text/css" href="dist/styls.css">
<script src="dist/build.js"></script>
</head>
<body>
<h1>hello</h1>
<h2>hello</h2>
<p>hello <span>hello world</span></p>
</body>
</html>
我的项目目录
main.js里面移入所有需要打包的文件
import {hello,hello1} from './script/hello1';
import {demo} from './script/hello';
import './style/hello.css';
import './style/hello.scss';
命令行npm start 启动项目 npm run build 编译项目
