ngx-spinner

What is ngx-spinner?

ngx-spinner is an Angular library that provides a variety of customizable loading spinners to indicate the loading state of a web application. It is easy to integrate and offers a wide range of spinner types and configurations.

What are ngx-spinner's main functionalities?

Basic Spinner

This feature allows you to add a basic spinner to your Angular application. You can customize the background color, size, color, and type of the spinner.

<ngx-spinner bdColor="rgba(51,51,51,0.8)" size="medium" color="#fff" type="ball-scale-multiple"></ngx-spinner>

Conditional Spinner

This feature allows you to display the spinner conditionally based on a boolean variable. In this example, the spinner will be shown only when `isLoading` is true.

<ngx-spinner *ngIf="isLoading" bdColor="rgba(51,51,51,0.8)" size="medium" color="#fff" type="ball-scale-multiple"></ngx-spinner>

Custom Template

This feature allows you to use a custom template for the spinner. You can place any HTML content inside the ngx-spinner tag to create a custom loading indicator.

<ngx-spinner><div class="custom-spinner-template">Loading...</div></ngx-spinner>

Spinner Service

This feature provides a service to control the spinner programmatically. You can use the `show` and `hide` methods of the `NgxSpinnerService` to display or hide the spinner.

import { NgxSpinnerService } from 'ngx-spinner';

constructor(private spinner: NgxSpinnerService) {}

showSpinner() {
  this.spinner.show();
}

hideSpinner() {
  this.spinner.hide();
}
