There are package managers like NPM and Yarn. They handle the package installations a bit different.
When all the packages has been installed, does the package managers do anything more? When starting for example Vue with
yarn dev or
npm dev does the package managers do anything or are they just let the packages run?
What I'm really after is if the package installers affect the performance even after the packages has already been installed.
Does package installers affect the packages only on installation or all the time?
