angular2 rc6 - systemjs.config.js using subfolder /src/app

Question

On the angular2 quick start page: https://angular.io/guide/quickstart

with Angular2 rc6 , file systemjs.config.js has changed . I'm trying to change the folder /app/ accord to angular quick start by /src/app accord my app, so i'm not sure what i must to change in this file. I've tried some paths but it's not working, anyone can explain more about this file and how I use the paths. in this configuration i dont care about production or /dist , because i'm just testing angular. I was working before with webpack starters or angular-cli but new versions angular broke those packages, so i want to stay simple.

src/app/systemjs.config.js:

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',
      // angular bundles

Answer 1

To load modules in NodeJS, install SystemJS with:

npm install systemjs

If transpiling ES modules, install the transpiler plugin following the instructions from the transpiler project page.

Answer 2

I find the new systemjs.config from angular to be a bit more messy. This is what i use and it works great:

(function(global) {
    var map = {
            'app': 'src/app',
            '@angular': 'node_modules/@angular',
            'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
            'rxjs': 'node_modules/rxjs'
        },
        packages = {
            'app': { main: 'main.js',  defaultExtension: 'js' },
            'angular2-in-memory-web-api': {main: './index.js',defaultExtension:'js'}
            'rxjs': { defaultExtension: 'js' }
        },
        ngPackageNames = [
            'common',
            'compiler',
            'core',
            'http',
            'platform-browser',
            'platform-browser-dynamic',
            'router',
            'forms'
        ],

        tests = [
            'core/testing',
            'common/testing',
            'compiler/testing',
            'platform-browser/testing',
            'platform-browser-dynamic/testing',
            'http/testing',
            'router/testing',
            'forms/testing'
        ];

    function packUmd(pkgName) {packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.min.js', defaultExtension: 'js' }}

    ngPackageNames.forEach(packUmd);

    tests.forEach(function (test) {
        return packages['@angular/'+ test] = { main: '/bundles/' + test.replace(/\//, '-') + '.umd.min.js', defaultExtension: 'js' }
    })

    var config = {
        map: map,
        packages: packages
    };

    System.config(config);

})(this);

I think this looks much cleaner and understandable. The only thing you need to change if your app folder changes is: 'app': 'path-to-app/app'
