AOT 和 Roll-Up：只有捆绑包 main.js，没有其他

Question

我正在尝试根据 https://angular.io/docs/ts/latest/cookbook/aot-compiler.html#!#tree-shaking

实施 AOT 和 Rollup

I 运行 rollup per:"node_modules/.bin/rollup" -c scripts/rollup-config.js

结果是一个 build.js 文件，只有入口文件，没有其他内容。没有错误，只有一个警告：“'default' 是从外部模块 'rollup' 导入的，但从未使用过”

"aot" 文件夹确实包含所有相关的已编译 ngfactory 文件。

入口文件如下：

import { platformBrowser }    from '@angular/platform-browser';
import { AppModuleNgFactory } from '../aot/app/app.module.ngfactory';

platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);

汇总-js.config:

import rollup      from 'rollup'
import nodeResolve from 'rollup-plugin-node-resolve'
import commonjs    from 'rollup-plugin-commonjs';
import uglify      from 'rollup-plugin-uglify'

export default {
    entry: 'scripts/app/main.js',
    dest: 'scripts/app/build.js', // output a single application bundle
    sourceMap: true,
    sourceMapFile: 'scripts/app/build.js.map',
    format: 'iife',
    onwarn: function(warning) {
        // Skip certain warnings

        // should intercept ... but doesn't in some rollup versions
        if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }
        // intercepts in some rollup versions
        if ( warning.indexOf("The 'this' keyword is equivalent to 'undefined'") > -1 ) { return; }

        // console.warn everything else
        console.warn( warning.message );
    },
    plugins: [
        nodeResolve({jsnext: true, module: true}),
        commonjs({
            include: '../node_modules/rxjs/**'
        }),
        uglify()
    ]
}

和我的 systemjs 以防其相关：

(function (global) {
    System.config({
        paths: {
            // paths serve as alias
            'npm:': 'libs/'
        },
        // map tells the System loader where to look for things
        map: {
            // our app is within the app folder
            app: 'approot',
            appjit: 'approot',
            // angular bundles

        },
        // packages tells the System loader how to load when no filename and/or no extension
        packages: {
            app: {
                main: './app/main.js',
                defaultExtension: 'js'
            },
            appjit: {
                main: './app/main-jit.js',

            },
            rxjs: {

            },
            'libs/text-mask-core/': {
                main: "textMaskCore.js",
                defaultExtension: 'js'
            },
            'libs/angular2-ui-switch': {
                main: "index.js",
                defaultExtension: 'js'
            }
        }
    });
})(this);

我的文件夹结构如下：

[visual studio 项目]/scripts/aot
[visual studio 项目]/scripts/app
[visual studio项目]/scripts/app/main.js
[visual studio 项目]/scripts/rollup-config.js
[visual studio 项目]/scripts/tsconfig-aot.json

我的环境：

对比 2015
Angular: 2.4.0
节点：v5.5.0
打字稿：2.0.10
汇总：0.41.4
rollup-plugin-node-resolve: 2.0.0
rollup-plugin-commonjs: 7.0.0
rollup-plugin-uglify: 1.0.1

Answer 1

要使 AOT 正常工作，您需要确保生成的是 es6 模块加载语法：

Rollup 只能使用具有导入和导出语句的 Tree Shake ES2015 模块。

tsconfig.json:

{
    "compilerOptions" {
        "module": "es6",
         ...
     }
}

Answer 2

我也在关注官方的 angular2 AOT guilde myself and due to lack of a simple working example I have created this github repository。希望对你有帮助。

如果您是 windows 用户，您绝对应该能够在 git-bash 终端中使用它（由我测试）。

Answer 3

在您的 [visual studio 项目]/scripts/aot 文件夹中，应该有一个 main.ts 文件，visual studio 将使用 t[ 将其编译为 main.js =19=]sconfig.json 但不是 tsconfig-aot.json，检查你的 main.js 文件，如果它看起来像

"use strict";
 var platform_browser_1 = require("@angular/platform-browser");
 var app_module_ngfactory_1 = require("./app.module.ngfactory");
 platform_browser_1.platformBrowser().bootstrapModuleFactory(app_module_ngfactory_1.AppModuleNgFactory);

您需要更新 tsconfig.json:

    {
     "module": "commonjs",
    }

至

   {
     "module": "es2015",
   }
