Angular has released its latest version, Angular 7.0. In this article, we will explore the following points:

What’s New in Angular 7.0
While creating a new Angular application, the Angular CLI will prompt the user to select if they want to add features like Angular routing or the format of stylesheets they want to use in their application.
Angular 7.0 applications will use the Bundle Budget feature of the Angular CLI to warn developers if the application bundle size exceeds the predefined limit. The default value for the warning is set to 2MB and for error is 5MB. This value is configurable and can be changed from the angular.json file. This feature enhances the application performance considerably.
The Component Dev Kit (CDK) of Angular Material also receives some new features as part of this update. The two newly added feature of CDK is mentioned below:
1. Virtual Scrolling
If you are trying to load a large list of elements then it can affect the application performance. The can be used to load only the visible part of the list on the screen. It will render only the items that can fit on the screen. When the user scrolls through the list then the DOM will load and unload the elements dynamically based on the display size. This feature is not to be confused with infinite scrolling which is altogether a different strategy to load elements. You can read more about Virtual Scrolling here.

The following questions are very pertinent:
With Angular, we can call a web service to get an image as a Blob, convert that to an image and display it on a web page. This may sound like a straight and standard use case but I ended up spending a lot of time trying to get this to work and a lot of asking around. This has been one of the main motivations to write this article.
What I Wanted to Do
To begin with, I am building a website that displays thumbnails retrieved from a URL. On clicking on the thumbnail, the full sized image loads in a new page. Like a typical carousel, but the catch is that the thumbnail is generated dynamically and does not load from or stored on the local machine.

Angular Select Has an Empty Value
Often, I’m faced with this problem while implementing a select (dropdown) in Angular. Here I have tried to walk through why Angular adds an empty value at the beginning of your select list.
