[Vuejs]-Is it possible to setup development mode environment on running Ubuntu machine (Server) for vuejs project

If you want to continue your devlopements on this live machine you will not want to build it each time you modify something so just run your usual script (npm run serve / yarn serve). This script use development as default environment variable (see https://cli.vuejs.org/guide/mode-and-env.html).

If you still want to build it, I think you will must build it each time you modify something no matter the environment variable due to the generation of new files.

Hope this help you.
