Typescript utility type to extract the target (generic) type of an injection token #2135
Conversation
…e of an injection token.
This allows to write injected dependencies like:
- given the following injection token:
```ts
const MyToken = new InjectionToken<Promise<Array<string | number>>>('my-token');
```
you can write:
```ts
type MyTokenTargetType = InjectionTokenTargetType<typeof MyToken>;
class MyClass {
constructor(@Inject(MyToken) someField: MyTokenTargetType) {}
}
```
instead of:
```ts
const MyToken = new InjectionToken<Promise<Array<string | number>>>('my-token');
class MyClass {
constructor(@Inject(MyToken) someField: Promise<Array<string | number>>) {}
}
```
