I have a custom module that uses a js file defined in:


Works fine. I want to use a different file within a theme; from the documentation it looks like I should drop the new js file in


but it does not seem to be working. After running setup:static-content:deploy the pub/static/etc directory contains the same myfile.js that is in the Vendor/Module rather than in the theme. (pub/static/frontend/vendor/theme/en_US/Vendor_Module/js/sub/directory/myfile.js)

How do I override a modules javascript file (contained in a sub directory) in a theme?

You have to use requirejs-config.js to override js files of module :

Step-1: To do this, place requirejs-config.js file in your theme root folder ( same path where your registration.php, theme.xml is placed ) and content will be like :

* See COPYING.txt for license details.

var config = {
    "map": {
        "*": {
            "jsmodule-identifier": "js/file-override"

Step-2: copy js file from module folder and place that file in your theme/web/js/file-overrid.js folder

NOTE : to verify file mapping identifier, view source of your site html page and check requireis-config.js file
