Vaadin 14 without internet

how can i build a “vaadin 14 project” without internet? npm and nodejs are already installed
but needed “node_modules” are not. is it possible to provide this modules as
downloaded/installed “packages”?

Sebastian has created a docker configuration for a local NPM repository / nexus, so that after an initial download no internet connection is needed afterwards. Please have a look here:
