I am wanting to use App Configuration to store both configuration and feature flags (using the Feature Manager) for both Frontend and Backend. Frontend is in Angular and Backend is .NET Core Web API. They run on separate App Services. I understand how to use the Feature Manager for the Backend but I don't see any guidance or npm package for the end. I see the REST APIs for App Configuration, but I am worried about the frequency of the calls and also exposing the entire configuration settings to the Frontend.
Is there any guidance or npm package I should be referencing/using?
