I am a beginner in the world of Angular2. It is known that in Angular2, there is a way to reference a file using a relative path by defining moduleId : module.id in the component meta data. However, I have tried doing it this way and keep encountering the following error:
Error: (SystemJS) module is not defined
I have created a Plunker showcasing a simple Angular2 app here.
The file structure is very basic and shown below:

The contents of each part are detailed as follows:
config.js:
System.config({
// Use TypeScript for compilation
transpiler: 'typescript',
// TypeScript compiler options
typescriptOptions: {
emitDecoratorMetadata: true,
module: "commonjs"
},
meta: {
'typescript': {
"exports": "ts"
}
},
paths: {
'npm:': 'https://unpkg.com/'
},
// Map tells the System loader where to look for things
map: {
'app': './app',

packages: {

},

}
});
app.component.ts:
import { Component } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'app',
templateUrl: 'app.component.html'
})
export class AppComponent {
}
To check out other files, you can refer to the Plunker link provided. I have also included module: "commonjs" in typescriptOptions. Do you see any issues with my code?
