webpack 配置案例for angular babel

1、dev.js:

const webpack = require(‘webpack‘);
const webpackUglifyJsPlugin = require(‘webpack-uglify-js-plugin‘);
const path = require(‘path‘);
const ExtractTextPlugin = require(‘extract-text-webpack-plugin‘);
const HtmlWebpackPlugin = require(‘html-webpack-plugin‘);
function root(__path) {
  return path.join(__dirname, __path);
}
const config = {
    entry: [
        "webpack-hot-middleware/client?reload=true",
        // 这里是你的入口文件
        "./src/index.js",
    ],
    output: { //输出目录
        publicPath: "",
        path: __dirname,
        filename: ‘bundle.js‘,
    },
    module: {
        rules: [{
            test: /\.jsx?$/,
            use: [{
                loader: ‘babel-loader‘, //只需要babel就可以写ng2的代码了
                options: {
                    presets: [‘es2015‘, ‘es2016‘, ‘es2017‘, ‘stage-0‘], //使用的presets
                    plugins: [‘transform-decorators-legacy‘] //使用的babel插件
                }
            }],
            exclude: /node_modules/
        }, {
            test: /\.scss$/,
            use: ExtractTextPlugin.extract({
                fallback: "style-loader",
                loader: "css-loader!autoprefixer-loader?{browsers:[‘last 6 Chrome versions‘, ‘last 3 Safari versions‘, ‘iOS >= 5‘, ‘Android >= 4.0‘]}!sass-loader",
            }),
        }, {
            test: /\.png$/,
            use: {
                loader: ‘file-loader‘,
                options: {
                    name: ‘../img/[name].[ext]‘
                }
            }
        }]
    },
    plugins: [
        new webpack.optimize.OccurrenceOrderPlugin(),
        new webpack.ContextReplacementPlugin(  //这个是ng需要用的插件，以免报错
            // The (\\|\/) piece accounts for path separators in *nix and Windows
            /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
            root(‘./src‘), // location of your src
            {} // a map of your routes
        ),
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoEmitOnErrorsPlugin(),
        new ExtractTextPlugin(‘css/style.css‘)
        /*new HtmlWebpackPlugin({
            title: ‘index‘,
            hash:true,
            template: ‘index.ejs‘, // Load a custom template (ejs by default see the FAQ for details)
        })*/
    ]
};
module.exports = config;

2、server.js:

var webpack = require(‘webpack‘),
    webpackDevMiddleware = require(‘webpack-dev-middleware‘),
    webpackHotMiddleware = require(‘webpack-hot-middleware‘),
    config = require("./config/dev.js"),
    express = require(‘express‘),
    app = express(),
    compiler = webpack(config);
app.use(webpackDevMiddleware(compiler, {
    publicPath: config.output.publicPath,
    noInfo: true,
    stats: {
        colors: true,
        progress: true
    }
}));
app.use(webpackHotMiddleware(compiler, {
    noInfo: true,
    publicPath: config.output.publicPath
}));

app.get(‘*‘, function(req, res) {
    var fileName = req.url;
    console.log(fileName);
    if (fileName == ‘/‘) {
        res.sendFile(__dirname + ‘/index.html‘);
    }else{
        res.sendFile(__dirname + fileName);
    }
});
app.listen(8087,‘0.0.0.0‘);

4、index.js:

import ‘reflect-metadata‘;
import ‘zone.js‘; //这两个是为了兼容angular2正常使用而导入的插件
import { platformBrowserDynamic } from ‘@angular/platform-browser-dynamic‘;

// import { enableProdMode } from ‘@angular/core‘;

import { NgModule } from ‘@angular/core‘;
import { BrowserModule } from ‘@angular/platform-browser‘;

import App from ‘./test.js‘;
import Test from "./test2.js";
@NgModule({
  imports: [ BrowserModule ],
  declarations: [
    App,
    Test   //声明所有的组件，这样才能使用组建
  ],
  bootstrap: [ App ] //启动组建，这样index.html 中才能使用该标签
})
class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

5、test.js:

import { Component } from ‘@angular/core‘;
import Test from "./test2.js";

@Component({
  selector: ‘my-app‘,
  template: `
    <h1>sdfjsdfkj</h1>
    <h2>Have {{ what }}</h2>

    this.what = "a good time!";
    this.toChildData=‘sdfksdfdjs‘;
  }

import {
	Component,
	Input
} from ‘@angular/core‘;

@Component({
	selector: ‘test-app‘,
	template: `
		<div (click)="testfn()">{{testData}}</div>  //事件促发案例
