I'm not sure when to use what.
with nuxt build you get two directories(client & server) that means you are actually deploying node.js server(i.e. express, right?)
with nuxt generate you get .html
It seems both ways you can have good SEO which nuxt aims at. And to me, nuxt generate option seems more consize since it doesn't envolve server.
What am I missing here? Why should I use nuxt build and get server code mixed up?
