Adding subdomains for Progressive Web Apps

Site URL: http://http/yourhistoryapps.com

I have set up a website to provide access to my Progressive Web App samples. I am using a PWA builder (Thorium Builder) that requires that the server has a PHP engine with the SQLite3 extension enabled. Is this configuration available on the SquareSpace personal plan or do I need to upgrade to a higher level plan to import and format my PWA?

Thanks.

I am not entirely sure what you want to do, but if you want to host your PWA on Squarespace, I'm afraid that it isn't possible😕 

This is what I do with my application:

1. My app is hosted on Sitegrounds as a subdomain - app.sparkplugin.com.
2. My website is hosted on Squarespace on the main domain - sparkplugin.com.

I use some DNS records for this to work.
