How to get rid of the warning .ts file is part of the TypeScript compilation but it's unused

Question

I Just updated angular to latest 9.0.0-next.4. I am not using routing but suddenly after updating I keep seeing this warning. How Do I remove this warning

Answer 1

For me, the problem was that I was using:

loadChildren: () => import('./components/admin/_admin.module').then(m => m.AdminModule)

in my routes.ts file but wasn't importing module. So if I just put

import { AdminModule } from './components/admin/_admin.module';

it solves it.
