Example
typescript
import { InjectionToken } from '@angular/core';
import { provideValue } from '@dasch-ng/utils';
const API_URL = new InjectionToken<string>('API_URL');
// Type-safe: value must be a string
provideValue(API_URL, 'https://api.example.com');
// Type error: number is not assignable to string
// provideValue(API_URL, 123);
