module verf Similar project?

Yes, i also checked it and both modules having same functionality.

I've spoken with el1_1el and we've taken a look at the differences between both modules. The conclusion is that they are complementary because Views Entity Reference Filter uses the Drupal\views\Plugin\views\filter\InOperator base class and Entity Reference Exposed Filters uses the Drupal\views\Plugin\views\filter\ManyToOne base class, each with their own specific use case. That said, we also concluded that both modules are solving a highly similar issue and are probably best combined to prevent duplication of work.

Both of us were also aware of [#2429699?], but agreed that this functionality needs to stay available in contrib for the foreseeable future, given the fact that core issues can take very long to land.

Given the fact that both modules have similar usage statistics, but Views Entity Reference Filter has cleaner code and test coverage, we've decided that it's best to merge Entity Reference Exposed Filters into Views Entity Reference Filter and provide an upgrade path for existing users.

#3062753: [PLAN] Merge Entity Reference Exposed Filters has been created to coordinate this effort.

Was just looking for a solution for this same use-case and came across this module. Did a bit more research and found the https://www.drupal.org/project/verf module as well.

There is a core issue that sounds like once it's committed (hopefully soon) that we may have the ability to create the entity reference dropdown select list for an exposed filter in native views. Maybe you can review https://www.drupal.org/project/drupal/issues/2429699 and comment.

In the mean-time maybe update the project page to indicate a similar project.

Thanks!
