Review comment:
Actually it gets even better: with setting custom prefix in Docker -> this
way node_modules will be installed and used from /cache/node_modules - not
messing with the code of the application. So even if we mount the sources from
local directory we will keep node_modules installed via Docker (and you need
both package and package-lock to make 'npm ci' works :)). Just checked.
