[笔记]ng2的webpack配置

欢迎吐槽

　　前言

　　　　angular.cn教程中用的是systemjs加载器，那用webpack应该怎么配置呢？本文 demo: https://github.com/LeventZheng/angular2-practice-colloection ( 非本人，而是群里大神共享的一份资料，感谢 )。webpack通过这份文件能实现：typescript转码，html、css、图片加载，less支持，区分开发环境，热更新，启动浏览器自动打开。

　　文件结构

　　　　

　　如何引入

// 组件中
@Component
template: require('./app.component.html'),
styles: [
    require('./app.component.css')
 ]
//或者less支持
styles: [
　　require('./app.component.less").toString( )
]

　　config -- helper.js

var path = require('path');
var _root = path.resolve(__dirname, '..');
function root(args) {
  args = Array.prototype.slice.call(arguments, 0);
  return path.join.apply(path, [_root].concat(args));
}
exports.root = root;

　　config -- webpack.dev.config.js

var webpack = require('webpack');
var helper = require('./helper.js');

var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var OpenBrowserPlugin = require('open-browser-webpack-plugin');

module.exports = {
	devtool: 'cheap-module-eval-source-map',

	entry: {
	    'polyfills': './app/polyfills.ts', // 补丁包
	    'vendor': './app/vendor.ts', // 库包，包含@angular/core等
	    'app': './app/main.ts' // 入口文件
	},

	output: {
	    path: helper.root('dist'),
	    publicPath: 'http://localhost:8080/',
	    filename: '[name].js',
	    chunkFilename: '[id].chunk.js'
	},

	resolve: {
	    extensions: ['', '.js', '.ts']
	},

	module: {
	    loaders: [
	      {
	        test: /\.ts$/,
	        loaders: ['awesome-typescript-loader', 'angular2-template-loader']
	      },
	      {
	        test: /\.html$/,
	        loader: 'html'
	      },
	      {
	        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
	        loader: 'file?name=assets/[name].[hash].[ext]'
	      },
	      {
	        test: /\.css$/,
	        exclude: helper.root('app'),
	        loader: ExtractTextPlugin.extract('style', 'css?sourceMap')
	      },
	      {
	        test: /\.css$/,
	        include: helper.root('app'),
	        loader: 'raw'
	      }
	    ]
	},

	plugins: [
	    new webpack.optimize.CommonsChunkPlugin({
	      name: ['app', 'vendor', 'polyfills']
	    }),

	    new HtmlWebpackPlugin({
	      template: 'app/index.html'
	    }), // 新建入口文件，并自动引入全部脚本 配合浏览器自动打开插件很方便

	    new ExtractTextPlugin('[name].css'),

	    new OpenBrowserPlugin({
	      url: 'http://localhost:8080'
	    }), // 浏览器自动打开

	    new webpack.DefinePlugin({
	    	_ENV_: 'production'
	    })
    ],

    devServer: {
	    historyApiFallback: true,
	    stats: 'minimal'
	}

};

　　补丁文件-- polyfills.ts

import 'core-js/es6';
import 'core-js/es7/reflect';
require('zone.js/dist/zone');
if (process.env.ENV === 'production') {
  // Production
} else {
  // Development
  Error['stackTraceLimit'] = Infinity;
  require('zone.js/dist/long-stack-trace-zone');
}

　   vendor文件-- vendor.ts

// Angular
import '@angular/platform-browser';
import '@angular/platform-browser-dynamic';
import '@angular/core';
import '@angular/common';
import '@angular/http';
import '@angular/router';
// RxJS
import 'rxjs';
// Other vendors for example jQuery, Lodash or Bootstrap
// You can import js, ts, css, sass, ...
