Angular elements Tutorials | web components examples

Angular is a framework for building SPA and hybrid applications.

with Angular, You can create Angular components, Which you can use only in the Angular application Each component you created in the angular application is a straightforward way to use it.

Suppose, How to use the Angular component in nonangular applications like any Java frontend or PHP or ruby on rails application.

Is this possible to use independent angular components outside of javascript frameworks?

It is possible by using Angular custom elements and web components.

Angular elements are introduced from the Angular 6 version onwards.

#What are Angular custom web elements?

Angular elements are normal angular components also called web components, that are packaged and shipped as minified versions to use in other applications

Custom elements are like normal HTML or DOM elements that wrap the entire functionality in a single element. Angular elements are custom components that build as mini

These are also called Angular web components.

Angular custom web elements are a simple way of using the minified angular version in any web application.

Angular provides the @angular/elements package to make custom web components elements

For example, Angular custom elements can be used as follows

<custom-elements data="dataobject"></custom-elements>

This will be used in Nonangular applications by This can be used like an adding javascript link

#why angular elements

There are many advantages of using angular elements

• Angular elements are nothing but components, So can be packaged and used in non-angular applications.
• These are reusable, develop a single component and reuse it in multiple applications independently.
• You can add angular elements to server-side code
• You can still use angular elements in angular applications

#Create an Angular project with the angular 12 version
