An example of an AI chatbot conversation about virtual scrolling in Angular.
What is virtual scrolling in Angular?
Virtual scrolling is a technique in Angular that allows you to efficiently render large lists by only displaying the items in view.
How does it improve performance?
It improves performance by reducing the number of DOM elements rendered at any time, which decreases memory usage and increases rendering speed.
Can you show me an example of how to implement it?
Sure! You can use the cdk-virtual-scroll-viewport from Angular's CDK. Here's a basic example:
<cdk-virtual-scroll-viewport itemSize="50" class="example-viewport">
<div *cdkVirtualFor="let item of items">{{item}}</div>
</cdk-virtual-scroll-viewport>
What are the limitations of virtual scrolling?
Some limitations include complexity in handling dynamic heights of items and potential issues with accessibility if not implemented correctly.
