Inputs :

[loadingText] : Accepts a string to display the text while the loading process.

[threshold] : Accepts time in milliseconds for threshold through which you can conditionally show the spinner only for expensive calls. Default is 500 ms.

default [loadingText] text would be blank.

<ngx-loading-spinner [threshold]="2000" [template]="template" [loadingText]="'Please wait...'"></ngx-loading-spinner>
