README

This module generates an import-map script tag to be used with JS modules.
Cross browser support is provided by https://github.com/guybedford/es-module-shims.

Install

composer require ubermanu/magento2-es-import-map

Create a example.mjs file into your module view/frontend/web/mjs folder:

// app/code/Vendor/Module/view/frontend/web/mjs/example.mjs
export const something = 'Hello world';

Add the following to any *.phtml template file:

<script type="module">
  import { something } from '/Vendor_Module/mjs/example.mjs';
  alert(something);
</script>

To use named imports, create an import-map.json file into the view dir of your module (or theme):

// app/code/Vendor/Module/view/frontend/import-map.json
{
    "imports": {
        "jquery": "https://cdn.skypack.dev/jquery"
    }
}
