Issue
I hope you all having a great day.
Here is the deal, whenever I load a lot of products from API that has one image each one of the products, the app kind of does a restart, and it loads from the beginning.
In the beginning it was with simple <img>
tag, I changed it to ion-img
, and I saw that there was a big difference using the ion-img
tag because it lazy loads the images.
But still, when I have loaded more that 40-60 products, and those images are loaded, the app still refreshes.
I remove the images, no images are shown, and the app works fine, but the app needs those images.
What might be the issue here? Am I missing something?
Click Here for Streamable 1 video
Here the client wants to see product categories with a lot products in it
Click here for Streamable 2 video.
Here the client wants to select a product, but when it does, the app restarts.
The second video, is where I have tried, to remove the top 15 products, when get the next 15 on infinite scroll, but a scrolling flick happens because of that.
Here it is Ionic Info:

here is a short code of the HTML that I am using to show the products and images.

<div *ngFor="let sub of allData">

<ion-button slot="end" (click)="goToShowAll()"size="small" fill="outline" class="seeAllButtonClass"><span style="margin: 10px;">voir tout</span></ion-button>
</ion-item>
</ion-col>
<ion-col size-xs="6" *ngFor="let prods of sub.products">
<div class="products-scroll">
<div>
<ion-card (click)="goToDetail(prods)">
<ion-img class="img" src="{{prods.image}}" alt=""></ion-img>
<div class="diviParagrafit">
<p>
{{prods.price}}<small>{{this.webService.config.currency}}</small>
</p>
<p>
{{prods.title}}
</p>
</div>
</ion-card>
</div>
</div>
</ion-col>
</ion-row>
</div>
</ion-grid>
This is the error I am getting on XCODE when the crash/restart happens:

Thank you very much.
Solution
The issue was the HTML TAG <ion-card>
.
After I removed that tag, and replaced it with <ion-grid>
everything was working fine on iOS.
But, thanks for letting me know about ion-virtual-scroll
@E. maginni , I will give it a try and use it in the future.
