Using Magento 2.4. I want to add some custom JS in the admin area.


var config = {
    map: {
        '*': {
            adminTheme: 'ClientQuote_AdminTheme/js/client-admin'

    paths: {
        'custom-script': 'ClientQuote_AdminTheme/js/client-admin'

I can see the above in the source of /static/adminhtml/Magento/backend/en_US/requirejs-config.js


], function () {
    'use strict';



Nothing is output.

Looking at the other scripts in requirejs-config.js they all seem to added in different ways.

Steps to Add Custom JS File in Magento 2 Admin Panel:

  1. Create app/code/ClientQuote/AdminTheme/view/adminhtml/requirejs-config.js file with the following code:

var config = { paths: { 'custom-script': 'ClientQuote_AdminTheme/js/custom-script' }, shim: { 'js-file-alias': { deps: ['jquery'] } } };

  1. Upload the JavaScript custom-script.js file at app/code/ClientQuote/AdminTheme/view/adminhtml/web/js/

  2. Put the following code in your .phtml file to load the JavaScript file

Note : add .phtml file via layout.xml

<script> requirejs(['jquery', 'custom-script'], function($){ // Your Code }); </script>

  1. Run the following commands:

php bin/magento setup:upgrade

php bin/magento setup:static-content:deploy -f

php bin/magento cache:clean

    I put my JS code in custom-script.js and a .phtml file? This is the confusion I have. Some tutorials say JS file and others .phtml

  • You can create .phtml file according to you. It is not fixed...
