Where do I keep the equivalent of Web.config appSettings in an Angular app?

Well, I've made this in the topmost folder side by side with main.ts and index.html:

export class Configuration {
   public routeToApi:string = "http://localhost:61995/";
}

 
 

It has its own file and what you see is the entirety of the file. I loop it in as a provider in my outermost module wrapping everything else and that allows me to pull it in at the constructor line of a service. Is this ghetto?
