Compine Laravel Vue components into different js files

I have a big project in Laravel, which have several front-ends, depending on logged user.

I also have a shared directory, where common components (like table, modal, etc.) can be used by the different front-end.

I want to compile each front-end to a different js file, so I can include only the relevant file for each user.

What I have till now:

webpack.mix.js:

mix.js('resources/js/app.js', 'public/js')
    .js('resources/js/frontendUser.js', 'public/js')
    .js('resources/js/frontendAdmin.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css');

Under resources/js I have a separate file for each front-end, for example frontendAdmin.js:

require('./bootstrap');

window.Vue = require('vue');

Vue.component(
    'frontend-admin-component',
    require('./components/FrontendAdminComponent.vue').default
);

const app = new Vue({
    el: '#app',
});

When I run npm run dev fiels are compiled correctly, and I can include them from the blade file:

<script src="" defer></script>

However, I get in console this error:

[Vue warn]: Unknown custom element: <frontend-admin-component>
 - did you register the component correctly? For recursive components,
 make sure to provide the "name" option.

Looks like the component behaves well, however I assume the warning exists for some reason and would like to fix it.

Is what I try to do have sense? What is wrong?
