Hello, I’m working on an Ionic application and trying to create a reusable modal component. I’m considering two approaches and would appreciate some guidance:
Scenario:
Imagine a ‘confirmation modal’ that displays a message and ‘Yes/No’ buttons. I need to use this modal in multiple parts of my application.
Shared Component:
- In both approaches, I would create a separate component (e.g.,
ConfirmationModalComponent
) to define the modal’s content (message, buttons) and logic (handling ‘Yes/No’ clicks).
Approach 1: Using <ion-modal>
Directly
- I would use
<ion-modal>
directly within each component where the modal is needed. - I would pass data to the
ConfirmationModalComponent
via input properties within the<ion-modal>
tag. - I would use
@ViewChild('modal') modal: IonModal;
to access the<ion-modal>
instance within the component and usethis.modal.dismiss()
orthis.modal.present()
to control its presentation and dismissal. - Each instance of
<ion-modal>
would handle its own presentation and dismissal.
Approach 2: Creating a Service with modalController
- I would create a service (e.g.,
ModalService
) that usesmodalController
to programmatically create and present theConfirmationModalComponent
. - The service would handle data passing to the
ConfirmationModalComponent
when creating the modal. - To dismiss or open the modal, I would call methods on the
modalController
instance (e.g.,modalController.dismiss()
,modalController.create()
,modal.present()
) from within the service or in the same component!. - The service would centralize the logic for presenting and dismissing the modal, ensuring consistent behavior across the application.
Questions:
- Maintainability: Which approach is generally considered more maintainable for a moderately complex application with many instances of this modal?
- Control and Customization: Does creating a service with
modalController
provide significant advantages in terms of control and customization over using<ion-modal>
directly? For instance, can it simplify global styling or pre-processing of data? - Best Practices: Are there established best practices for creating reusable modal components in Ionic?
- Performance: Is there a performance difference between the two approaches?
For simple modals, is the complexity of creating a resuable modal worth it, or should one opt for individual modals?
I’m also curious if these considerations apply similarly to other Ionic components like action sheets or alerts. I have a service for alerts or a toastService where i indeed benefit the use of that. But what about modals?
Thank you for your insights!
