Inject dependancy

    constructor(
        private spinnerService: NgxLoadingSpinnerService
    ) { }

Use show() method to display the loading spinner.

this.spinnerService.show();

Use hide() method to hide the loading spinner once the processing is done.

this.spinnerService.hide();

Example

    this.spinnerService.show();
    this.http.get(GLOBAL['CONFIG_URL'])
        .subscribe(data => {
            this.spinnerService.hide();
        });

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.

[timeout] : Accepts time in milliseconds to hide the spinner automatically. Default is 5000 ms.

default [loadingText] text would be blank.

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

<ngx-loading-spinner [threshold]="2000" [timeout]="4000" [template]="template" [loadingText]="'Please wait...'" [zIndex]="9999"></ngx-loading-spinner>

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

app.component.ts

template: string =`<img src="http://pa1.narvii.com/5722/2c617cd9674417d272084884b61e4bb7dd5f0b15_hq.gif" />`
