How does vuejs introduce the module?

this question has puzzled me all the time

import modules into components like this. For example, I have to rely on these things for many components.
and then import them one by one. Will you repeatedly package these modules into the code when packing?
has previously used webpack packaging scripts and found that all scripts entered by import will be packaged into the code.

does not repeat packing, which has nothing to do with vue.
webpack will do dependency analysis, and the same module will be reused.
