Worked for me…! Thanks!
Hi, i have the same problem to build my PWA, so, i try to replace ionic cordova build browser --prod by
ionic cordova build browser --aot --minifyjs --minifycss --optimizejs --release
And it also freeze. I noticed that when i remove --oprimizejs flag the build process finish successfully so it seems that optimization process provides an issue during building process with --prod flag.
My problem is that without optimization process, the server does not detect changes in my PWA and i must always double cache clean my browser to see my modifications…
Thanks, this solved my issue
It worked for me, thanks.
