How to connect jQuery and plugins to it in Webpack (ES2015)?

Question

JavaScript

Good afternoon,
I have such a problem:
when connecting jQuery plugins, they do not see jQuery itself. I do it like this:

import $ from 'jquery'
    import jQuery from 'jquery'
    window.$ = $;
    window.jQuery = jQuery;
        import tooltip from 'bootstrap'

Please tell me the right way...
