404 GET /app - Angular2 quickstart

I'm trying to migrate my app based on the old angular2 quickstart to the new one (which has new folder hierarchy).

When hitting npm start I'm getting 404 GET /app error. It's important to mention that my app.module.ts file is placed under /app/modules/app/app.module.ts

I tried to change paths with no luck but I still suspect that it's something that is related to my configurations.

main.ts:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/modules/app/app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

systemjs.config.js:

/**
 * System configuration for Angular 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
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',

      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

Solution

Change your systemjs.config.js

In the package entry change the app to app: {main: 'app/modules/app/app.module', defaultExtension: 'js'}

If you have a bundle of your app created somewhere you should point the app key to that bundle instead of app.module.
