i'm deploying remote server local development environment ( vagrant / homestead ). in project have huge directories both node_modules , bower_components . want use rsync deploy project on remote server think it's ok skip mentioned giants. why? by writing question confirm 2 things: 1) since triggered gulp tasks on local, right not copy 2 vendor directories if assets copied, minified , versioned using laravel elixir? compiled styles , scripts synced. (that's non-laravel project) use elixir in gulpfile.js it's simplicity 2) or should deployment process include installing assets (like npm install ) on remote server , running tasks? think it's wrong in case. if example won't able install , run npm on remote? so in nutshell. can consider node_modules , bower_components essential resources during development , redundant once deployed? yes right in once javascript app has been transpiled, dependencies(node_modules, bower_componenets, etc)
