When defining a component decorator in Angular 2, mixing tabs and spaces can lead to an unhandled exception

After refactoring my Angular 2 component code and adding some tabulations, the code suddenly stopped working. Surprisingly, when I removed the tabs (spaces), it started working again.

@Component({
  templateUrl   : './app.component.html',
  styleUrls     : ['./app.component.scss'],
  encapsulation : ViewEncapsulation.None
})
export class AppComponent {}

The initial code snippet did not work as expected. However, the following modification made it work:

@Component({
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {}

This behavior is quite odd and unexpected.

UPDATE: I am using webpack along with awesome-typescript-loader and angular2-template-loader for transpiling the code.

When the code includes tabs and spaces, it compiles to this result: https://i.sstatic.net/sgRpp.png

On the other hand, without any tabs or spaces, the compilation leads to a different outcome: https://i.sstatic.net/vdjRA.png

It appears that the webpack loaders are having trouble recognizing the code when there are spaces between the ":" in the object decorator definition.

Answer №1

Ah, the culprit was indeed the Angular2-template-loader. The problem was resolved after upgrading to v0.6.0.
