Create a non constructable ProviderToken

[deebloo]

Yes this would allow that. Till now I have just used a class with a "value" prop but this would allow any type.

Could even put simple values in there?

const name = 'Grain';
const token = new InjectionToken(name); // would be nice to optionally give it a name
const providers = [{ provide: token, factory: () => 'Salt']

[deebloo]

One other note. Adding a default value would be optional. So this would be another way to require manually defending a provider.

Found a minor issue with the new example in the readme (typescript is complaining), I hope this is related enough:

Type 'typeof Logger' is not assignable to type 'ProviderToken'.
Cannot assign an abstract constructor type to a non-abstract constructor type.ts(2322)
provider.d.ts(7, 5): The expected type comes from property 'provide' which is declared here on type 'Provider'

abstract class Logger {
  abstract log(...args: any[]): void;
}

const app = new Injector([
  {
    provide: Logger as ProviderToken<Logger>, // manual typecast to supress
    factory() {
      return console;
    }
  }
]);

I'll double check the example locally. There should be no need to type cast anything. I think I just have the Logger class those wrong.

@Phoscur ah the problem with the docs is the abstract token. I thought I had added the ability to support abstract classes but turns out that is missing from the provider definition. I updated the docs to reflect the correct usage.
