webpack2和angular2搭建的项目

github地址:项目链接

npm install，安装依赖包

npm run dev，启动本地工程，在localhost:1699进行预览

package.json{ "name": "angular-webpack", "version": "1.0.0", "description": "webpack2 & angular2", "scripts": { "dev": "babel-node ./src/config/dev.js" }, "author": "Travis Lee", "license": "ISC", "dependencies": { "@angular/common": "~4.0.0", "@angular/compiler": "~4.0.0", "@angular/core": "~4.0.0", "@angular/forms": "~4.0.0", "@angular/http": "~4.0.0", "@angular/platform-browser": "~4.0.0", "@angular/platform-browser-dynamic": "~4.0.0", "@angular/router": "~4.0.0", "core-js": "^2.4.1", "es6-shim": "^0.35.3", "reflect-metadata": "^0.1.8", "rxjs": "5.0.1", "zone.js": "^0.8.4" }, "devDependencies": { "babel-core": "^6.25.0", "babel-loader": "^7.1.0", "babel-preset-es2015": "^6.24.1", "clean-webpack-plugin": "^0.1.16", "css-loader": "^0.28.4", "extract-text-webpack-plugin": "^2.1.2", "path": "^0.12.7", "style-loader": "^0.18.2", "ts-loader": "^2.1.0", "typescript": "^2.3.4", "typings": "^2.1.1", "uglifyjs-webpack-plugin": "^0.4.6", "webpack": "^2.6.1", "webpack-dev-server": "^2.5.0", "webpack-merge": "^4.1.0" }}

webpack配置文件开发版：

import path from 'path'import config from "./webpack.config"import merge from "webpack-merge"import webpack from "webpack"import webpackDevServer from "webpack-dev-server"import { format } from 'util'let PORT = 1699;let PUBLIC_PATH = "http://localhost:" + PORT + "/";let webpackConifg = merge(config, { devtool: "source-map", //debug: true, webpack2 已切换到plugins中，据说在3中将取消 entry: { main: [ format("webpack-dev-server/client?%s", PUBLIC_PATH), "webpack/hot/dev-server", "./src/main.ts" ] }, output: { path: path.resolve(__dirname, '../../dist'), publicPath: PUBLIC_PATH, filename: '[name].js' }, plugins: [ new webpack.HotModuleReplacementPlugin() ]})const compiler = webpack(webpackConifg);new webpackDevServer(compiler, { inline: true, hot: true, port: PORT, stats: { colors: true }}).listen(PORT, 'localhost', (err) => { console.log(123)})

搭建中遇到的问题：

The URL 'localhost:1699/sockjs-node' is invalid，

该问题是由于webpack配置文件中的publicPath前边没有加http://，导致url解析失败

Uncaught reflect-metadata shim is required when using class decorators，

这个问题是由于main.ts文件中没有引入 reflect-metadata和zone.js
