AOT & Roll-Up: Only bundles main.js and nothing else

Question

I am trying to implement AOT and Rollup per https://angular.io/docs/ts/latest/cookbook/aot-compiler.html#!#tree-shaking

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

and the result is a build.js file with just the entry file and nothing else. There are no errors and just one warning: "'default' is imported from external module 'rollup' but never used"

The "aot" folder does contain all the relevant compiled ngfactory files.

Following is the entry file:

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

platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);

The rollup-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()
    ]
}

and my systemjs just in case its relevant:

(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',

                defaultExtension: 'js'
            },
            appjit: {

            'libs/angular2-ui-switch': {

                defaultExtension: 'js'
            }
        }
    });
})(this);

My folder structure is as follows:

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

My environment:

• VS 2015
• Angular: 2.4.0
• Node: v5.5.0
• Typescript: 2.0.10
• rollup: 0.41.4
• rollup-plugin-node-resolve: 2.0.0
• rollup-plugin-commonjs: 7.0.0
• rollup-plugin-uglify: 1.0.1

Answer 1

In your [visual studio project]/scripts/aot folder, there should be a main.ts file, visual studio will compile it to main.js using tsconfig.json but not tsconfig-aot.json, check your main.js file, if it looks like

"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);

you need to update in your tsconfig.json:

    {
     "module": "commonjs",
    }

to

   {
     "module": "es2015",
   }

I also was following the official angular2 AOT guilde myself and due to lack of a simple working example I have created this github repository. I hope it helps you.

If you are a windows user, you should definitely be able to get it working in git-bash terminal (tested by me).
