For testing purpose, we have modified the core file post-code.js which is in the path /vendor/Magento/module-ui/view/base/web/js/form/element and see it's working fine. So we have decided to override the file post-code.js.

For overriding, we have followed the below steps:

  1. Created and copied the files on


  1. Run the below commands

    php bin/magento setup:upgrade
    php bin/magento setup:di:compile
    php bin/magento setup:static-content:deploy -f

But it's not working as expected.

Could anyone please tell me how to override the "post-code.js"?


Try this,

You must rename your module-ui to Magento_Ui

Copy the file from below path




then run the below commands.

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

Hope this helps.

  • Thanks. Could you please explain why we need to change the module name from module-ui to Magento_Ui? – Siva Apr 24 at 12:15
  • It is your module name will reside in registration.php inside module-ui module, that should be placed there – Prathap Gunasekaran Apr 24 at 13:16
