Angular variable change for production?

Question

Angular

How to change some variables for production? There are addresses to which I send requests, for local development, but for production it is necessary to send requests to other addresses, how to do this?

Answer 1

To help you src\environments
There is environment.ts - it is used by default
When building the project:
ng build --prod
the --prod flag is substituted into the mask *.environment.ts
It is simply imported into the component:

import { environment } from 'src/environments/environment';

export class AppComponent implements OnInit {
     url = environment.apiUrl;
}
