Webpack 2 不加载 Angular2 Typescript 应用程序的导入

Question

我正在尝试在使用打字稿的中型 angular2 项目上实施 webpack。但是当我运行 webpack 它只捆绑我在配置文件中指定的 2 个文件。它从不遍历导入树并加载其余模块。

我已经设置了一个相当简单的配置。我想得到它只是捆绑打字稿开始。然后我将继续捆绑更多文件。

当我将 import {} 从 "x" 语法更改为 var {} = require("x"). webpack 可以工作，但是会抛出数百个错误，因为它无法解析从 @angular2 目录导入的任何内容。

如何让 webpack 遍历 'import' 语句并将多个文件打包到结果中？

我的配置如下

webpack.config.js

var webpack = require('webpack');
var path = require('path');

module.exports = {
    context: path.join(__dirname, 'wwwroot/app'),
    entry: {
        'vendor': './vendor',
        'app': './main'
    },
    resolve: {
        extensions: ['', '.ts', '.js']
    },
    output: {
        path: path.join(__dirname, 'wwwroot/built'),
        filename: '[name].bundle.js'
    },
    module: {
        loaders: [
            {
                test: /\.ts$/,
                exclude: /node_modules/,
                loaders: ['ts', 'angular2-template-loader']
            }
        ]
    }
};

tsconfig.json

{
  "compilerOptions": {
    "noImplicitAny": false,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "system",
    "moduleResolution": "node"
  },
  "exclude": [
    "node_modules",
    "wwwroot/lib",
    "bin"
  ]
}

main.ts

import { bootstrap } from '@angular/platform-browser-dynamic';
import { HTTP_PROVIDERS } from '@angular/http';
import { disableDeprecatedForms, provideForms } from '@angular/forms';

import { AppComponent } from './app.component';
import { APP_ROUTER_PROVIDERS } from './app.routes';

bootstrap(AppComponent, [
    APP_ROUTER_PROVIDERS,
    HTTP_PROVIDERS,
    disableDeprecatedForms(),
    provideForms()
]).catch(err => console.error(err));

运行ning webpack 上的控制台输出：

Answer 1

尝试将 module 从 system 更改为 commonjs，如下所示：

{
  "compilerOptions": {
    "noImplicitAny": false,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "commonjs", // <--- from 'system' to 'commonjs'
    "moduleResolution": "node"
  },
  "exclude": [
    "node_modules",
    "wwwroot/lib",
    "bin"
  ]
}
