Thanks for pointing out Primefaces, I did not know it. It looks really good - I am just not sure about their licensing and price (I developed apps for personal use). The components look great and apparently one can also use TailwondCSS natively.

VueRequest also looks nice - I use fetch to get the data but this library avoids the boilerplate.

Thansk for these ideas - I will jump once again in something new :)
