If you are looking to create a simple fade in and out effect for a component using Angular, you can achieve this by utilizing the :enter and :leave events:
import { Component, HostBinding } from '@angular/core';
import { animate, style, transition, trigger } from '@angular/animations';
@Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss'],
animations: [
trigger('host', [
transition(':enter', [
style({ opacity: 0 }),
animate('240ms linear', style({ opacity: 1 })),
]),
transition(':leave', [
style({ opacity: 1 }),
animate('240ms linear', style({ opacity: 0 })),
])
]),
]
})
export class TestComponent {
@HostBinding('@host') host() {
return true;
}
}
To use the component with the fade effect, include it in your HTML like this:
<app-test *ngIf="someBoolean"></app-test>The animation should work properly on entering the component. However, if the element is not fading out when the component is being removed (when someBoolean is set to false), it may be due to a missing piece of code or configuration.
If the fade-out effect is not working as expected, you may need to troubleshoot and determine what is causing the issue.
