Invoke a function and assign it to an export variable

I have a query regarding a file containing an export constant that is utilized to construct a navigation bar in CoreUI. However, I am exploring methods to generate dynamic JSON data within other Components or the same file and then inject it into the exported constant. Any suggestions?

import { environment } from '../../../environments/environment';
export const navItems = [
  {
    name: 'Create Form',
    url: environment.URL,
    icon: 'icon-plus',
  },
  {
    name: 'Views',
    url: '#',
    icon: 'cil-applications',
    children: [
        // Placeholder for injecting dynamic json data here
     ]
  }
]

Using InjectionToken to provide the value for your module is recommended.

To do this, you can create an interface for the object and reference it within your module:

const menuItems: YourObjectInterface = {
  ...
}

export const MENU_ITEMS = new InjectionToken<YourObjectInterface>('menu.items');

...

providers: [{ provide: MENU_ITEMS, useValue: menuItems }]

Then in your component, you can inject it as follows:

constructor(@Inject(MENU_ITEMS) items: YourObjectInterface) { }
