I have created my application using systemjs...everything works fine. Now i would like to create a bundle file, but for some reason my application is requesting my module as a separate http request? I thought it should all be included in my bundle.js file? Not sure if i have set something up incorrectly?
My application is stored in the wwwroot/app folder of my application root (asp.net 5 project).
I use gulp to convert my .ts file in .js and put them into wwwroot/dist/app.
I then gulp to convert all these .js files into my bundle.js which is then stored in wwwroot/dist/bundle.js
Now when i execute the page, my bundle.js file is loaded, the .html files are requested (as expected), but a request is made for public.module? I have a feeling it is something to do with this line in the app.routing.ts file loadChildren: 'app/public.module' where the module is loaded dynamically..
I have checked my bundle.js file and no reference of PublicModule is included? Why?

This looks clearly a bug in systemjs-builder.
https://github.com/systemjs/builder/issues/728
The workaround is adding '.js' in all import statement.
e.g.
import { AppModule } from './app.module';
needs to be
import { AppModule } from './app.module.js';
It worked for me with this solution.

I'm going to preface this question by saying that I'm fairly new to Angular 2 and Angular in general, so the odds are that this question is going to have a really easy answer. Anyway, here it is. I've been trying to a create a website, and my issue is that Angular won't insert my components. It stays at the part where it says Loading... and won't load in my things, even when they're simple HTML. I'll provide what I'm pretty sure are the pertinent files, but if you need anything more, don't hesitate to ask.

I grabbed the ng-book 2 as it seemed like a quality way to figure out Angular2. As a heads up, I've never used any of these module loaders or anything before and I've had very limited use of npm and node so all the terminology and assumed knowledge can be quite confusing.
ng-book 2 uses node but I figured I might as well start off using my usual .NET MVC server as that is what I'll be pairing Angular 2 with at work.
My current issue is apparently in the module loading, as I just keep getting 404 errors when systemjs is trying to load angular packages.

The layout of the project is like this
And what I end up getting with this are requests like
zone.js:101 GET http://localhost:18481/#angular/core 404 (Not Found)
The first thing I see is that probably your systemjs config is not applied, because you have
<script resource="~/app/resources/systemjs.config.js"></script>
Why do you have resource here? systemjs.config.js contains plain javascript code that should be executed like any other script.

Can also see here that in my Network tab, the CKEditor.js file is being loaded.
Anyone have any idea why this isnt working?
This means that your CKEDITOR JavaScript didn't load.
The file CKEditor.js refers to the Angular2 component which doesn't contain the editor itself. That file is part of the repo.
So you need to include ckeditor.js yourself.
I'm not sure about the condition on line 159, which should detect missing CKEDITOR JavaScripts. Maybe show the entire error message on what line inside CKEditor.js it throws the error.
The problem is that in routing i have to click twice to trigger ngOnInit code.
The weird thing is, if I have two routes: A and B, and I clicked on A first, it will trigger the constructor only, and if I clicked on B after it, it will trigger A's onInit before calling B's constructor.
using angular 2.0.0-rc.4 and routes 3.0.0-beta.2

Update:
I'll include html of list and the component nested inside if it helps

[mediaItemToWatch] ="mediaItem"
(deleted)="onMediaItemDeleted($event)"
[ngClass]="{'medium-movies': mediaItem.medium === 'Movies', 'medium- series' : mediaItem.medium === 'Series'}" ></media-item>
MediaItem html:
<h2>{{mediaItem.name }}</h2>
<div>{{mediaItem.category}}</div>
<div>{{mediaItem.year}}</div>
<div class="tools">
<a class="delete" (click)="onDelete()">
remove
</a>

Media Item ts:
import {Component, Input, Output, EventEmitter} from '#angular/core';
import {FavoriteDirective} from './favorite.directive';
#Component({
selector: 'media-item',
directives: [FavoriteDirective],
templateUrl: 'app/media-item.component.html',
styleUrls: ['app/media-item.component.css']
})
export class MediaItemComponent {
#Input('mediaItemToWatch') mediaItem;
#Output('deleted') delete = new EventEmitter();
onDelete() {
this.delete.emit(this.mediaItem);
}
}
It seems
vendors.js:2291 Unhandled promise rejection Error: Cannot match any routes: ''
causes change detection to not run
To avoid this error add a route for the '' path like
{ path: '', redirectTo: '/list', pathMatch: 'full' }
or
{ path: '', component: DummyComponent, pathMatch: 'full' }
I think better answer is to add "onSameUrlNavigation" option on
RouterModule.forRoot(
appRoutes,
{
useHash: false,
anchorScrolling: "enabled",
onSameUrlNavigation: "reload",
enableTracing: true,
scrollPositionRestoration: "enabled"
})
I pulled the latest angularjs2 seed application from github (https://github.com/angular/angular2-seed) and got it running in webstorm.
Now I wanted to add a simple load.ts file which preloads some components:
declare var System: any;
declare var esriSystem: any;
esriSystem.register([
'esri/geometry/Point',
'esri/geometry/geometryEngineAsync',
'esri/Map'
], function() {
// bootstrap the app
System.import('../app')
.then(null, console.error.bind(console));
}, {
outModuleName: 'esri-mods'
});
I would like to use this module inside a new map.service.ts: import { Map } from 'esri-mods'; it tells me that it cannot resolve file 'esri-mods'
The overall structure looks like this:
And the system.config.js as follows:
System.config({
transpiler: 'typescript',
typescriptOptions: {
emitDecoratorMetadata: true
},
map: {
app: 'src',
typescript: 'node_modules/typescript/lib/typescript.js',
angular2: 'node_modules/angular2',
rxjs: 'node_modules/rxjs'
},
packages: {
app: {
defaultExtension: 'ts',
main: 'app.ts'
},
angular2: {
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});
What is missing for the module to be usable within the application?
