googlemaps/v3-utility-library : ReferenceError: InfoBox is not defined

Can someone provide some help?

I am using Laravel 5.5 . I successfully implemented Google Maps APIs in my project (InfoWindows displaying with data). In order to customize the infoWindow, i use locally through a script the infobox.js downloaded from github link https://github.com/googlemaps/v3-utility-library/blob/master/infobox/src/infobox.js but every attempt to display an InfoBox fail. After many hours, digging in the code, i spotted that my code is failing at

var ib = new InfoBox(myOptions);

To confirm it is not related with my project code, i achieved a page with copy paste of the basic example of github at https://github.com/googlemaps/v3-utility-library/blob/master/infobox/examples/infobox-basic.html: But still have the same error :

ReferenceError: InfoBox is not defined

which Firebug related again to : var ib = new InfoBox(myOptions);

In case you doubt here is my copy of code rendering the error :

I am wondering if the setting of mix (for .js, .css etc...) on my Laravel Framework could be in cause? Did someone encounter such issue? ...I opened an issue on https://github.com/googlemaps/v3-utility-library/issues/423

Update------ Here below is my Mix File :

let mix = require('laravel-mix');

mix.js('resources/assets/js/app.js', 'public/js')
   .js('resources/assets/js/slider.js', 'public/js')
   .js('resources/assets/js/globalstat.js', 'public/js')
   .js('resources/assets/js/infobox.js', 'public/js')
   .sass('resources/assets/sass/app.scss', 'public/css').sourceMaps();

Solution

For Laravel Mix, mix.js() uses Webpack to bundle such as CommonJS or AMD modules.

For the infobox.js you included, it is not a javascript module and therefore it is not possible to use webpack bundle the assets.

Instead, you should use mix.scripts() to combine the plain js:

mix.scripts([
    'resources/assets/js/infobox.js'
], 'public/js/infobox.js');
