Angular is Google’s open-source reactive framework and continues to remain popular in 2021.
Many enterprises and large-scale companies rely on Angular to build their applications. Top technology job markets consistently seek out Angular developers. As Google uses the software in its own apps, it will remain in demand for years to come.
This article offers 5 tips on how to improve your Angular developer skills.
Learn how to add drag and drop functionality into your Angular app. See how Chrome’s DevTools can highlight bottlenecks. Discover why you should add lazy loading to your applications.
Read on to bolster your skillset and ignite your coding career.
1. Use Fewer $watchers in Your Angular Applications
Angular uses the MVC model. That means it must listen for every change to your app and report it down the line.
This is the Digest Cycle in AngularJS and it keeps track of scope changes through watchers.
However, using too many can severely decrease performance. Therefore, limit your $watch() methods and only keep track of variables that are vital to the flow of your app.
2. Learn Angular Drag and Drop In a Material Tree
The Material CDK now includes the Drag and Drop UI. That makes it quite simple to include drag/drop functionality in your Angular apps through boilerplate code.
The Material Tree component also brings a file explorer design to structure your data. Combining them produces powerful results where the user can reorder lists of linked data by dragging them up or down.

3. Use Chrome DevTools to Improve Your Developer Skills
The Google Chrome browser can assist you to develop your Angular apps.
Press F12 to open the DevTools pane and switch between mobile views, elements, source files, and the console. You can edit DOM elements on the fly along with CSS properties to change them in real-time.
Chrome DevTools even lets you find performance bottlenecks.
Open the Network and Performance tabs to view and record loading issues. You can identify the offending file and discover where the issues lie.
4. Keep Your DOM Small
Like watchers, remove unnecessary DOM elements to keep your app running smoothly.
Angular needs to keep track of all elements, whether the user can see them or not. Don’t hide them from view. Delete them entirely and add them programmatically if required.
5. Include Lazy Loading as Standard
Most Angular applications contain several pages. By default, the browser loads content from each linked page even if you don’t require them when initializing.
Lazy loading limits non-essential modules to reduce initial loading times.
This will also reduce your bundle sizes. And it improves the user’s experience as they can interact with your app more quickly.
