Next, provide configuration implementation for the library:

@NgModule({
    ...
    imports: [
        ...
        NgxAvatarLibModule.forRoot({
            provider: {
                provide: NgxAvatarLibConfigurationProvider,
                useClass: ExampleNgxAvatarLibConfigurationProvider
            }
        })
    ]
    ...
})
export class AppModule {
}

Example of the configuration:

import {Injectable} from "@angular/core";
import {
    NgxAvatarLibConfiguration,
    NgxAvatarLibConfigurationProvider
} from "@mindarchitect-ngx-libraries/ngx-avatar-lib";

@Injectable({ providedIn: 'root' })
export class ExampleNgxAvatarLibConfigurationProvider implements NgxAvatarLibConfigurationProvider {
    get Configuration(): NgxAvatarLibConfiguration {
        return {
            defaultAvatarImagePath: '/assets/',
            defaultAvatarImageFileName: 'avatar.jpg'
        };
    }
