ng-smart-modal is a lightweight Angular library for creating dynamic nested modals

Supported version of Angular 9 and higher

1) Install Library - 'npm i ng-smart-modal'

2) Inject service into component.

    constructor(
         private ngSmartModalService: NgSmartModalService
    ) {}

3) ngSmartModalService attach method will create instance from component and append template into document body. You can also pass ng-template with attachTemplate method with the same configs.

    public openModal(): void { 
     const modal: IModal<Component> = this.ngSmartModalService.attach(Component,
          {
             inputs: {},   // object;
             outputs: {}, // object;
             class: 'my-custom-class',        // string | string[];
             ignoreWhenRouterChanged: false, // boolean; (the modal automatically closes when changing the route, if enabled)
             ignoreBackdropClick: false,    // boolean;
             ignoreBackdrop: false,        //  boolean;
             ignoreAnimation: false,      // boolean;
             ignoreEsc: false,           // boolean;
             topPosition: 'center'      // could be 'px' | '%' | 'vh' 
           });
           
           this.ngSmartModalService.attachTemplateRef(templateRef);
    }

Input key names should be the same as attached component property names.

    export class TestModalComponent {
      public title: string;
      public user: {name: string, age: number};
    }
    
    public openModal(): void { 
         this.ngSmartModalService.attach(TestModalComponent, {
             inputs: {title: 'my-title', user: {age: 27, name: 'David'}}
         });
    }

To use output bindings assign them to component properties or local variables.

     export class AppComponent implements OnInit {
    
       private testModalClose$ = new EventEmitter<void>();
     
       constructor(
         private ngSmartModalService: NgSmartModalService
       ) {
       }
     
       ngOnInit(): void {
         this.testModalClose$.subscribe();
       }
     
       public openModal(): void {
         this.ngSmartModalService.attach(TestModalComponent, {
             outputs: {close$: this.testModalClose$}
         });
    }

    export class TestModalComponent {
      public close$ = new EventEmitter<void>();
    }

4) You can listen to component instance and modalsWrapper closeWrapper$ EventEmitters.

    modal.instance.event$.subscribe();
    modal.closeWrapper$.subscribe();

5) 'detach()' - method will remove last modal from document body. You can also pass index of a modal which you want to remove.

    this.ngSmartModalService.detach();
    this.ngSmartModalService.detach(modalIndex);

6) You can pass or remove classes to modals. You can also pass an index of a modal on which you want to add or remove class.

    this.ngSmartModalService.setClass(['my-first-custom-class', 'my-second-custom-class']);
    this.ngSmartModalService.removeClass(['my-first-custom-class', 'my-second-custom-class'], modalIndex);
