An example of an AI chatbot conversation about using OnPush strategy in Angular for performance optimization.
How do I use the OnPush change detection strategy in Angular?
The OnPush strategy in Angular optimizes performance by reducing the number of checks Angular performs. You can use it by setting the change detection strategy in your component's decorator.
What are the benefits of using OnPush?
Using OnPush can significantly improve performance, especially in large applications, by limiting change detection to only when input properties change or events occur.
Can you give me an example of how to implement it?
Sure! In your component, you can set it like this: @Component({ changeDetection: ChangeDetectionStrategy.OnPush }). Then, ensure your component's inputs are immutable.
Are there any drawbacks to using OnPush?
Yes, the main drawback is that it requires a good understanding of immutability and can lead to missed updates if not used correctly.
