How important is the app.js library (conflicts with another library from Bootstrap) in Laravel?

Question

JavaScript

Hello.
Some app.js is initially installed in Laravel, which (as it was found out by poke) does not allow the Dropdown button from Bootstrap to work, namely, it does not get along with Popper.js.
So far, it has been removed from the project.
But this is Vue (do I understand correctly?) - what if you need it later.
What to do?

Answer 1

So in app.js, out of the box, bootstrap is fully working, if you connected another one from above, then it’s clear that everything will break.
In app.js this is not a library, but your built application i.e. the whole front.
Out of the box, there immediately stands vue, bootstrap and all sorts of little things. Optionally changes to react altogether with a single artisan command.
