The first working version of SharePDF is now live, and all features are working as expected. Currently, it supports the following features:
PDF upload is correctly working, with proper sharing links
Shows view counts in dashboard whenever someone opens a shared PDF
PDF viewer has better controls now like jump to page, zoom in/out, fit to width, fit to page, rotate, etc. options.
Supports custom slug options for shared PDF URLs
I am still working on improving the performance and adding some more required features.
