I have a similar project with 5 pages of PDF applications along with Personal info for people we are keeping track of. I choose Firebase for this as it has a separate Database and Storage sections. No matter what File Format (mine are PDFs) you have, you can store the files on Storage. You can upload right on the Firebase Console or at a command line with their gsutil command:
gsutil -m acl ch -r -u firstname.lastname@example.org:O gs://<your-cloud-storage-bucket>
// Get a non-default Storage bucket
var storage = firebase.app().storage("gs://my-custom-bucket");
So we already have the tools to deal with Storage files built-in to Firebase.
The docs are in PDF format, which we all know to be unilaterally available to all. The client wanted a horizontal “slide show” of those PDF docs. I was working with Ionic’s ion-slide as I have done on other projects. I have NOT (yet) been able to use any PDF utility inside of the component. I have not given up on that and also looking at showing a single PDF with Back and Fwd buttons. I have been working with the ng2-pdf which I know works fine for displaying single PDF. Not done with this subject.
