Hello,

When I try to use PdfViewer with Angular 8, compiling with Ivy, I get :

Error: Type PdfViewerModule does not have 'ngModuleDef' property.
at getNgModuleDef (VM8703 vendor.js:68747)
at verifySemanticsOfNgModuleDef (VM8703 vendor.js:88543)

I guess the package is not ready yet ?

When you build without Ivy, you don't get the error

Which ng2-pdf-viewer version did you use?

Fixed in 5.3.1
