How to include external scripts in vue cli?

Question

webpack

Good afternoon.
The admin panel was bought and now the task is to implement it using vue.js and vue cli.

I can’t connect scripts, I also tried in public/index.html in the script tag - I get the error Uncaught SyntaxError: Unexpected token '<'

I tried one more way: I created the lib.js file in the scr folder and did import './assets/ in it ...', in this case the build didn't build at all, there wasn't even an error, so I ended up creating a new project with vue cli but didn't add eslint to check what was wrong.

As a result, I received an error - ReferenceError: jQuery is not defined

Screenshots below:


This is how they suggest doing it according to the instructions, but nothing about SPA is written there:

Answer 1

I manage to include jquery in public/index.html:

<title><%= htmlWebpackPlugin.options.title %></title>
<script src="/resources/jquery/3.4.1/jquery.min.js"></script>

where resources is a folder in public.
But I would still install not manually, but through npm . I checked, everything works.
