AssetMapper is great and upgrading web apps to AssetMapper is also great and not too complex.

But, managing bundle's web assets with AssetMapper is not possible at the moment.

To make it work, we'd need, at least, two things:

(1) A way to run importmap commands when developing the bundle locally. Maybe include a small binary with the component like we do in other components?

(2) A way to reference to bundle's assets in {{ importmap('...') }} Twig function. Maybe allow to use the typical bundle logic path such as importmap('@AcmeBundle/app') ?

But before doing anything, we must decide if want to support AssetMapper in bundles.

I looked at the most starred GitHub repos that include the symfony-bundle tag and this is what I found:

So, not many popular third-party bundles need this feature.

But, there are others that could use it:

• Apps like Sylius which internally are made out of bundles and many of them inclde web assets
• Private apps that also use bundles internally to split their logic

Thanks!
