    How to call a configurable external JS URL in magento2

    How to call a configurable external JS URL in magento2

    Today I will explain in this article, that how you can create a configurable JS external URL and then map it with another js in magento 2. Suppose you stuck in a condition, i.e. you have to call only one JS with some conditions, like if mode is production then ABC.js should call and if mode is desug then XYZ.js should call , so this blog will be very helpful for you. So lets get started. At first you will need to call a template file on your page, i.e. test.phtml. In this file write the configurable JS url, for e.g. :

    <?php if ($mode == "production") {
        $url = "https://abc.production/payment.js";
    } else {
        $url = "https://abc.sandbox/payment.js";
    } ?>
    // $url is customized JS url
    <script>
       require.config({
           map: {
               '*': {
                   'customjs':  '<?php echo $url ?>'
               }
           }
       });
    </script>

    Whenever test.phtml is executed, above code will make an entry to requirejs-config.js  file. Now how do you call this in your other JS files. So lets have a look below in your other newcustomjs.js file.

    /*browser:true*/
    /*global define*/
    define(
        [
            'ko',
            'jquery',
            'Magento_Checkout/js/view/payment/default',
            'Magento_Checkout/js/model/quote',
            'customjs' // here the js file is mapped
        ],
        function (
            ko,
            $,
            Component,
            quote,
            custom // you can refer this object to use customjs functions
        ) {
            'use strict';
            
            ...........
            // and you can call your customjs functions easily
            .........
    });

    Now when newcustomjs.js is called then only your customjs file invoked. Hope this blog will help you to build applications in your module in a better way. Try this and if you have any query then just comment below 🙂
