How can I improve performance in Angular and Vue applications?
An example of an AI chatbot conversation about optimizing performance in Angular and Vue apps.
How can I improve performance in Angular and Vue applications?
To improve performance, consider lazy loading modules, optimizing change detection, and using trackBy in ngFor for Angular. For Vue, use computed properties and the async component feature.
What is lazy loading and how does it help?
Lazy loading is a technique where you load components or modules only when they are needed, reducing the initial load time and improving performance.
Can you give examples of using trackBy in Angular?
Sure! In Angular, you can use trackBy in ngFor like this: *ngFor='let item of items; trackBy: trackByFn', where trackByFn is a function that returns a unique identifier for each item.
What tools can I use to measure performance?
You can use tools like Google Lighthouse, Chrome DevTools, and WebPageTest to measure and analyze the performance of your Angular and Vue applications.
