I have an app built in ionic 4 in which we have a page where we display all the available items. This item can be range from 0 to 1,00,000. Currently when the list is loaded the app performance goes down by which the app closes unexepectedly.
So I am looking for a solution that can help me to improve the performance of the item loading and rendering.
Maybe you can try using a virtual scroll.
There's a tutorial just here : https://www.youtube.com/watch?v=qgPNdoB1zhk&ab_channel=SimonGrimm
The HTTP request will still get 100 000 items, but you will display just a part of it into your template.
Another way to display it without burning your PC is to use a simple pagination.
