Please checkout my new purgeTSS
CLI.
Just install it globally on your machine.
[sudo] npm i -g purgetss
Use any tailwind.tss, fontawesome.tss, materialicons.tss and lineicons.tss classes in your views.
Run purgetss
inside your project’s root folder before compiling your App.
purgetss
And as simple as that, you’ll have a purged app.tss
file with only the styles used in your App.
