I am currently working on developing a versatile modal component that has the ability to be called from within the same modal itself.
Is there any way to configure the component and modal in such a manner that when the reusable component is triggered, it automatically closes any previous instances?
You can find my project on Stackblitz through the following link:

I suggest implementing a single modal...
Let me provide you with the step-by-step approach
Now, we can start by defining our Service
import { Injectable } from "@angular/core";
import { BehaviorSubject, Subject } from "rxjs";
interface IModalParams {
component: any;
config?: any;
title?: any;
}
@Injectable()
export class MyService {
private isModalOpen$ = new BehaviorSubject(false);
private component;
private config;
private title;
public showModal({ component, config, title }: IModalParams) {
this.component = component;
this.config = config;
this.title = title;
this.isModalOpen$.next(true);
}
}
In the above code snippet, we define a method called showModal which takes in parameters for the component, configuration, and title of the modal.
We also have a BehaviorSubject named isModalOpen$, which allows subscribing properties to be notified whenever a user opens a new modal.
ngOnInit() {
this.myService.isModalOpen$.pipe(
tap(() => this.modalRef?.hide()),
filter(isOpen => isOpen)
).subscribe({
next: () => {
const {component, config, title} = this.myService
this.modalRef = this.modalService.show(component, config);
if(title) {
this.modalRef.content.title = title;
}
}
})
}
In the above code snippet, we subscribe to isModalOpen$ and handle the opening or closing of the modal component.
this.myService.showModal({
component: ModalContentComponent,
config: {
ignoreBackdropClick: false
},
title: "Modal with component"
})
}
In other components, you can utilize the showModal method as demonstrated in the example above.
