Is there a specific directive in Angular that allows for variable declarations using the "

This interesting piece discusses the usage of a let-name directive in the template:

<ng-template #testTemplate let-name>
   <div>User {{ name }} </div>        
</ng-template>

Can anyone tell me if this is a part of the standard angular/core directives or is it something unique to angular/cdk or perhaps an innovation by the author?

Answer №1

According to information sourced from the Angular Documentation

The concise Angular microsyntax allows for easy directive configuration using a user-friendly string format. This string is then translated by the microsyntax parser into attributes on the <ng-template>

For instance, within Angular, the microsyntax streamlines the following code:

<div *ngFor="let item of items">{{item}}</div>

Rather than having to write it out in a longer format like this:

<ng-template ngFor let-item [ngForOf]="items"><div>{{item}}</div></ng-template>.
