How to display empty ng2-pdfjs-viewer when no file provided

Question

I'm using ng2-pdfjs-viewer to display pdfs in my angular page:

<ng2-pdfjs-viewer [pdfSrc]="src">
</ng2-pdfjs-viewer>

Behavior : i get src from server, when it's not empty or null it's working correctly, but when null or emty ng2-pdfjs-viewer crashes.

Expeced : display an empty ng2-pdfjs-viewer when src is null or empty (or a loading indicator inside)

Does browser console say anything? any error there? – Shumail Sep 27 '19 at 14:43 — Shumail, Sep 27 '19 at 14:43

Put *ngIf with this component. It will solve null or empty src case.

    <ng2-pdfjs-viewer *ngIf="src" [pdfSrc]="src"> 
</ng2-pdfjs-viewer>
