webpack2和angular2搭建的项目

github地址:项目链接

1. npm install，安装依赖包
2. npm run dev，启动本地工程，在localhost:1699进行预览

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

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
