Utilizing Angular service in a separate file outside of components

In my library file product.data.ts, I have a collection of exported data that I need to update based on a value returned by a featureManagement service. Our team regularly uses this service and includes it in the constructor of any component using standard DI.

Is there a way to inject this service into the file without relying on a constructor or class?

const productUpdateLDFlag = () => {
  // We cannot directly use the service here, but I am unsure how to inject it.
return this.featureManagement.getCurrentFlagValue(SwitchesProperty.productVersion);
};

rest of file

export const PRODUCTS_COMBINED: Array<Products> = [ProductA, ProductB, productUpdateLDFlag(), Product D]

What is the best way to utilize DI to bring in the featureManagement service and leverage it within the data.ts file?

Answer â„–1

In a scenario where you need to inject dependencies, you have the option to employ the inject(MyService) method.

To establish the injection context, you can utilize the

EnvironmentInjector.runInContext()
function.
