Is there a way to configure viewer.js without editing its code?

[chan-dev]

I'm having an issue where adding a file query parameter throws an error even if i don't use the value of the query parameter as the pdf source.

For instance, here's a sample URL
chrome-extension://extensionId/src/pdfviewer/web/viewer.html?file=http://localhost:3000/apis/pdfstorage/someRandomId

NOTE:

• it is just named viewer.html but it's our own custom html file

Here's how i actually use the library:
I just manually add the value in [src] @Input

<ngx-extended-pdf-viewer
  [src]="'assets/ws-checklist.pdf'"
  [handTool]="false"
  [showFindButton]="true"
  [useBrowserLocale]="true"
  zoom="100%"
  height="100vh"
></ngx-extended-pdf-viewer>

Upon searching the internet, it seems like they're all pointing to editing the source file.
One example is from this stackoverflow answer

Essentially, i have a couple of questions:

1. Does pdf.js looks at ?file=value query parameter even if you don't use it in your code?
2. Is the only solution right now is to edit the viewer.js?

Yes, you're right. I can't see how anybody benefits from the ?file= URL parameter, so I should remove it. This is the offending line:

Would you mind to open a ticket?

I've already converted this into a new issue ticket. Thanks a lot.
On a second thought, is there ever a use case for file query parameter when using this library? I know it's useful for using the raw pdf.js file.

It may also be put to good use in an Angular application, but I'm afraid most developers don't expect such a feature, so it only confuses them. It'd confuse me, FWIW. The default approach of Angular is using a router, so I assume most developer prefer to do just that.
