<p>I was able to fix this by copying the entire vector-maps plugin into my project (instead of importing via node_modules). Then I added <code>import * as mdb from 'mdb-ui-kit/js/mdb.es.min'</code> as an import statement in <code>vector-maps.js</code>. This import statement ultimately resolved the <code>mdb is not defined</code> error. See my Astro file below.</p>

<p>MDB could you please fix the plugin library so vector-maps can be loaded without using <code>type=module</code>? Thanks.</p>

<pre class="prettyprint"><code>---
import Layout from 'src/layouts/Layout.astro';
import 'src/components/mdb-vector-maps/css/vector-maps.min.css';
---

</div>

And how did you do it with umd import?

This will work:

  <!-- MDB ESSENTIAL -->
  <script type="text/javascript" src="js/mdb.umd.min.js"></script>
  <!-- MDB PLUGINS -->
  <script type="text/javascript" src="plugins/js/vector-maps.min.js"></script>

This is not a bug.

VectorMaps can be used without "module" script tag but not with es modules. It is clearly stated in our documentation that

Currently, the plugin is only compatible with the basic MDB package imported in UMD format.

und_crc priority commented 2 months ago

I tried both es and umd modules, but neither worked.

You may import Vector maps like this:

  <script type="module">
    import * as mdb from './js/mdb.es.min.js';
    window.mdb = mdb;
  </script>

  <script type="module">
    import * as VectorMap from './plugins/js/vector-maps.min.js';
  </script>

If you don't want to use script tags use the same syntax in JS files but make sure that mdb and VectorMap are imported in different files.

Importing the script as type=module won't work in our use case. How can I import vector-maps from the mdb node_module (similar to calendar)? Thanks.

Import mdb and plugin in separate script tags or separate JS files. It should help.

und_crc priority commented 2 months ago

That does not work

und_crc priority commented 2 months ago

For reference, I am able to import the calendar plugin using the following code without any issues.

import * as mdb from 'mdb-ui-kit/js/mdb.es.min';
window.mdb = mdb;
import Calendar from 'mdb-calendar';
