Have you tried to implement pdf.js using asp.net core?

[imbenjogadia]

Hi everyone, I hope you are doing well. I need your help, I am trying to implement the pdf.js viewer using asp.net core, have anyone tried it before? I am getting an error on the /lib/pdfjs/web/locale/en-US/viewer.ftl. I am using the pdf.js version 4.0.269

Thank you.

By default, Kestrel doesn't recognize ".ftl" as a valid web extension.

Add this to your Program.cs or wherever you build the web app, where "app" is WebApplication:

var contentProvider = new FileExtensionContentTypeProvider();
contentProvider.Mappings[".ftl"] = "application/octet-stream";
app.UseStaticFiles(new StaticFileOptions
{
    ContentTypeProvider = contentProvider
});
