Connecting laravel mix plugins?

Question

Laravel

Laravel 5.5
I'm trying to connect the "sweetalert2" plugin I did
"npm install --save sweetalert2"
In "assets/app.js" I wrote require('sweetalert2') I
ran npm run watch
I got a notification that everything was built.
When I try to display an example, it says "swal is not defined"
What am I doing wrong? And how do third-party plugins connect?

Answer 1

var swal = require('sweetalert');
