Custom template

template : Accepts HTML which generates the loading spinner. You can apply additional css to design your own spinner, or can just pass *.gif image to show the loading spinner.

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

zIndex : Accepts a z-index css property for loading text.

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.

app.component.html : both are optional if not provided default would be shown.

<ng4-loading-spinner [threshold]="2000" [template]="template" [loadingText]="'Please wait...'" [zIndex]="9999"></ng4-loading-spinner>

threshold="2000" : This will show the loading bar for the only processes which will take time more 2 secs.
