express - NodeJS/ExpressJS production deployment -

ok, may dumb question, or entirely unnecessary, i'll risk sounding idiot know sure.

i have prototype application frontend using angular2 , backend (really restapi server) using node/express. have frontend stuff building/minifying/browserfying etc. production deployment.

is there typically done backend server same? bundling js files , minifying them or anything?

i can't seem find without including steps using express server views/content. in prototype, expressjs restapi server, frontend deployed separate web server. may moot this, since it's not going large of system, i'm curious.
