Angular 5 webpack 3 aot

Question

我正在尝试使用webpack 3和angular 5进行构建,但网上有很多教程,没有显示完整的示例没有问题,到目前为止,我有以下配置:(对于那些有疑问的人路径 - 我在java应用程序中使用它)

webpack.config.aot.js:

const webpack = require("webpack");
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const ngToolsWebpack = require('@ngtools/webpack');

module.exports = {
    context: __dirname + "/src/main/webapp/resources/script/",
    entry: {
        app: "./core/main.aot.ts",
        vendor: "./vendor.ts",
        polyfills: "./polyfills.ts"
    },
    output: {
        filename: 'js/[name].js',
        chunkFilename: "js/chunks/[id].chunk.js",
        publicPath: "resources/compiled/",
        path: __dirname + '/src/main/webapp/resources/compiled'
    },
    resolve: {
        alias: {
            STYLES: __dirname + "/src/main/webapp/resources/css/",
            SCRIPT: __dirname + "/src/main/webapp/script/"
        },
        extensions: [".js", ".json", ".scss", ".ts"]
    },
    module: {
        rules: [
            {
                test: /[\/]angular\.js$/,
                loader: 'exports-loader?angular'
            },
            {
                test: /\.html$/,
                loader: 'raw-loader'
            },
            {
                test: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/,
                loader: '@ngtools/webpack'
            }
        ]
    },
    plugins: [
        new ngToolsWebpack.AngularCompilerPlugin({
            tsConfigPath: './tsconfig.aot.json',
            entryModule: './src/main/webapp/resources/script/core/i18n/app.module.en#AppModule'
        })
    ]
};

tsconfig.aot.json:

{
  "compilerOptions": {
    "module": "es2015",
    "moduleResolution": "node",
    "target": "es5",
    "noImplicitAny": false,
    "sourceMap": true,
    "mapRoot": "",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "es2015",
      "dom"
    ],
    "outDir": "lib",
    "skipLibCheck": true,
    "rootDir": "."
  },
  "exclude": [
    "node_modules/*",
    "target/*"
  ],
  "angularCompilerOptions": {
    "genDir": "./src/main/webapp/resources/script/factory",
    "rootDir": ".",
    "baseUrl": "/"
  }
}

main.aot.ts:

import {platformBrowser} from '@angular/platform-browser';
import {enableProdMode} from "@angular/core";
import {AppModuleNgFactory} from '../factory/app/app.module.ngfactory';

enableProdMode();

platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);

文件结构(简化):

- webpack.config.aot.js
- tsconfig.aot.js
- src/
  - main/
    - webapp/
      - resources/
        - script/
          - vendor.ts
          - polyfills.ts
          - core/
            - main.aot.ts
            - i18n/
              - app.module.en.ts

(如果我没有展示相关内容,请告诉我)

所以当我想用它来构建它时 webpack -p --config ./webpack.config.aot.js

我收到以下错误:

ERROR in src/main/webapp/resources/script/core/main.aot.ts(5,34): error TS2307: Cannot find module '../factory/app/app.module.ngfactory'.

哪个声音非常合理,因为那里没有AppModuleNgFactory,但正如我在教程中看到它应该是在构建时使用genDir生成的,我是对的吗？(请注意,如果我省略app /文件夹,那么路径看起来'../factory/app.module.ngfactory'我得到同样的错误)

是否使用@ ngtools/webpack指向aot构建中不存在的AppModuleNgFactory？

什么是AppModuleNgFactory？在角度站点上几乎没有关于它的任何文档的文档

我应该在配置中更改什么才能成功生成构建？

如果我将主文件更改为引导AppModule本身,它会成功构建,但在浏览器中我会收到NullInjectorError: No provider for t!错误

没有缩小它显示: No provider for CompilerFactory!

Answer 1

看来 @ngtools/webpack 可以从原始主文件处理引导模块工厂本身，例如 webpack 条目应该是：path_to_file/main.ts

main.ts 包含：

platformBrowserDynamic().bootstrapModule(AppModule);

整个事情将自行处理，无需额外配置！

真是太神奇了
