This is a Composer plugin that, when added as a dependency, causes Drupal package dependencies to be installed into a typical Drupal directory structure in web/
instead of a flat structure in vendor/
.
It's similar to using composer/installers
with composer-installers-extender
like Acquia Lightning
, except you can pull it in as a single dependency instead of setting up a bunch of stuff in composer.json
for every project.
