2019 may or may not be the year, but I'm sure it's coming - this inexplicably expansive land grab of web application functionality by client-side technologies is going to peak, and things will start to swing back towards the server side.
Why the client-side has seen such an era of fecundity in recent years is beyond me. Perhaps because there was a real problem with leaving the job to jquery. Regardless, eventually there's just going to be too many available solutions but not enough solidified and proven methods where everything you need has been packaged together neatly because trial and error and years of iteration have pulled the optimal toolchains together and left the others by the wayside.
The way everything client oriented is just sort of floating around with no real scheme to it creates a lot of possibilities but at the same time much confusion and exhaustion. Eventually, (hopefully) there will come the standards.
