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 import * as mdb from 'mdb-ui-kit/js/mdb.es.min' as an import statement in vector-maps.js. This import statement ultimately resolved the mdb is not defined error. See my Astro file below.

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

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.

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


Kamila Pieńkowska staff answered 3 months ago


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.


und_crc priority commented 3 months ago

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.


Kamila Pieńkowska staff answered 3 months ago


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


und_crc priority commented 3 months ago

That does not work


und_crc priority commented 3 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';
