生活随笔
收集整理的這篇文章主要介紹了
一个简易的webpack开发环境
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
本菜鳥搭建的入門級別的webpack環(huán)境， 僅供參考，webpack學(xué)精很不容易，每個插件作者都有自己的思想。 待我吃透了再說。 待我后續(xù)完善， 目前可以
- 提取圖片
- 服務(wù)器環(huán)境 支持跨域 熱更新
- ES6語法降級
- less 轉(zhuǎn) es6
//壓縮js插件
var UglifyJSPlugin = require(
'uglifyjs-webpack-plugin');
//
var webpack = require(
'webpack');
//提取公共代碼
var ExtractTextPlugin = require(
"extract-text-webpack-plugin");
//在使用時將不再需要import和require進行引入， ProvidePlugin進行實例初始化后，jquery就會被自動加載并導(dǎo)入對應(yīng)的node模塊中
var providePlugin = new webpack.ProvidePlugin({ $:
'jquery', jQuery:
'jquery',
'window.jQuery':
'jquery' });
module.exports = {entry: { //多入口index:
'./src/js/index.js',goodsInfo:
'./src/js/goodsInfo.js'},output: {//多出口filename:
'[name].js',path: __dirname +
'/out',publicPath:
'http://localhost:8080/out'},module: {rules: [{
test: /.js$/, use: [
'babel-loader'] }, //js語法降級// {
test: /.css$/, use: [
'style-loader',
'css-loader'] }, //css{
test: /.css$/,use: ExtractTextPlugin.extract({fallback:
"style-loader",use:
"css-loader"})},{
test: /.jpg|png|gif|svg$/, use: [
'url-loader?limit=8192&name=./[name].[ext]'] },//設(shè)置尺寸名字和擴展名{
test: /.less$/, use: [
'style-loader',
'css-loader',
'less-loader'] }]},plugins: [new UglifyJSPlugin(),new webpack.optimize.CommonsChunkPlugin({name:
"commons",filename:
"commons.js",minChunks: 2}),new ExtractTextPlugin(
"[name].css"),providePlugin],devServer: {quiet:
false, //控制臺中不輸出打包的信息open:
