Handling PDF/DocX/Excel Documents

I have three file types I would like to handle in my app: PDF, .docx, and Excel files. What should be the strategy to open these? I first have to download them from the server. Do I store them using the FuseJS/Storage and then open them with LaunchUri pointing to their locally stored file?

I haven’t tested, but yes, that sounds like the strategy. Fuse doesn’t know how to handle those files, but your OS hopefully does. There is no guarantee that iOS and Android devices have installed the neccessary apps to support those files though.
