shipsCRUD is not a function error if put js file in webpack.mix.js

Hello,
In my laravel 6 app I use js files which I attach in in blade file
resources/views/ship/index.blade.php like :

@endsection

@section('scripts')

<link rel="stylesheet" href="{{ asset('/css/jquery.dataTables.min.css') }}" type="text/css">

<script src="{{ asset('js/jquery.dataTables.min.js') }}"></script>
<script src="{{ asset('js/mustache.min.js') }}"></script>

<script src="{{ asset('js/pages/ship.js') }}"></script>

<script>
/*<![CDATA[*/

var oTable
jQuery(document).ready(function ($) {
var shipsCRUD = shipsCRUD('list', // must be called before jQuery(document).ready(function ($) {
<?php echo $appParamsForJSArray ?>
);
shipsCRUD.onCRUDPageInit('list')
});

/*]]>*/
</script>

@endsection
 

Code (JavaScript):

and that worked ok for me when I put js/pages/ship.js file under /public/ directory.
Having in resources/js/pages/ship.js :

let frontend_home_url
let this_id
let this_csrf_token

function shipsCRUD(page, paramsArray) { // constructor of backend Ship's editor - set all from referring page and from server

frontend_home_url = paramsArray.frontend_home_url;
this_dataTablesLengthMenuArray = paramsArray.dataTablesLengthMenuArray;
this_csrf_token = paramsArray.csrf_token;

if (page == "edit") {
this_id = paramsArray.id;
}
if (page == "list") {
this.ShipsLoad()
$(".dataTables_filter").css("display", "none")
$(".dataTables_info").css("display", "none")
}
} // function shipsCRUD(Params) { constructor of backend Ship's editor - set all from referring page and from server


shipsCRUD.prototype.onCRUDPageInit = function (page) { // all vars/objects init
initCRUD()
} // shipsCRUD.prototype.onCRUDPageInit= function(page) {
 

Code (JavaScript):

But I have got a hint that it is a wrong way to have editable file under /public/ and I put
file ship.js as resources/js/pages/ship.js
and I added 1 line in webpack.mix.js :

mix.js('resources/js/app.js', 'public/js')
.sass('resources/sass/app.scss', 'public/css')
...
.js('resources/js/pages/trip-details.js', 'public/js/pages')
.js('resources/js/pages/ship.js', 'public/js/pages')

and running command :
[code]
npm run watch-poll

I have a file moved at 
/public/js/pages/ship.js
with content :

Code (JavaScript):

But in in console I got error :

app.js:73188 Uncaught TypeError: shipsCRUD is not a function
at HTMLDocument.<anonymous> (ships:429)
at mightThrow (app.js:72895)
at process (app.js:72963)
 

Code (JavaScript):

1) Why I got error in this way and how to fix it ?

2) Also could you please advice a proper way to publish jquery.dataTables.min.css/js files? If I want to avoid putting them under /public/, which is valid way?

Thanks!

 

I got a hint and in the end of the resources/js/pages/ship.js
I added line :

window.shipsCRUD = shipsCRUD;
 

Code (JavaScript):

It fixed my error, but now I got a console error :

Uncaught TypeError: this.ShipsLoad is not a function

Code (JavaScript):

Method ShipsLoad is defined in the same resources/js/pages/ship.js file:

let frontend_home_url
let this_id
let this_csrf_token
function shipsCRUD(page, paramsArray) {  // constructor of backend Ship's editor - set all  from referring page and from server
  frontend_home_url = paramsArray.frontend_home_url;
  this_dataTablesLengthMenuArray = paramsArray.dataTablesLengthMenuArray;
  this_csrf_token = paramsArray.csrf_token;
  if (page == "edit") {
    this_id = paramsArray.id;
  }
  if (page == "list") {
    this.ShipsLoad() // I CALL this.ShipsLoad
    $(".dataTables_filter").css("display", "none")
    $(".dataTables_info").css("display", "none")
  }
} // function shipsCRUD(Params) {  constructor of backend Ship's editor - set all  from referring page and from server
shipsCRUD.prototype.onCRUDPageInit = function (page) {  // all vars/objects init
  initCRUD()
} // shipsCRUD.prototype.onCRUDPageInit= function(page) {
shipsCRUD.prototype.runSearch = function (oTable) {
  oTable.draw();
}
shipsCRUD.prototype.ShipsLoad = function () { // ShipsLoad DEFINITION
  oTable = $('#get-ship-dt-listing-table').DataTable({
    processing: true,
    ...
  }); // oTable = $('#get-ship-dt-listing-table').DataTable({
}

Code (JavaScript):

Actually ship.js has several methods, which I call from blade tamplate or from the other methods of ship.js file.
Which is correct way of ShipsLoad definition and calling ?
