Build / transpile everything on npm build

[vikoivun]

Currently a very large swath of build stuff happens on the first run of node server. Causing major downtime on upgrades.

Most everything should be done on npm build.

I'd say this sort of depends on #414. It's silly to implement a new build pipeline using an obsolete Webpack.

Yeah, so this should be ready to be done now!

[jonnetanninen]

Would this be easiest for @akx to implement as he already has the knowledge of the current implementation? It will take me quite some time to understand what is going on here...

[Rikuoja]

Probably @vikoivun has the best understanding of how we want to get the static build up to date now.

@vikoivun so, what may be your preference ? The yarn start already transpiles everything into /dist as static files, which can be used. So, how'd you want the build script to be different ? we can add certain optimisations

[vikoivun]

kerrokantasi-ui will have minimal server side rendering for FB. So the build only needs to be neat and clean. It would be nice if "production mode" would serve all client side stuff from previously processed files. Ie. it should start fast.

[Rikuoja]

Well, this is a big thing. But should be done if there is time.
