getting opaquetoken to work in angular 2

Question

Hi I can't get opaquetoken to work, did I overlooked anything?

Plunk

in app.ts

export const SbToken = new OpaqueToken('myToken');
const testfile = 'Hello';

in ngModule

providers: [{provide:SbToken, useValue:testfile}]

in test.cmp

constructor(@Inject(SbToken) private token) {
      console.log(token)
    }

and i'm getting error (in punker, which uses systemJS i guess)

(SystemJS) Error: Can't resolve all parameters for TestComponent: (?).

within my webpack Project I get similar error

Can't resolve all parameters for LoginPage: (NavController, SelfbitsAngular, ?).

Answer 1

You have a cyclic dependency between app.module and test.component. This problem was already answer in angular 2 OpaqueToken
