How to compile new dependencies without restart elixir iex or phoenix server

Thank you in advance for your comment.
My project is an open source project right now and the codes are accessible(link).
It is the responsibility of the site administrator to install each plugin for him/her self CMS.

When we force the low elixir knowledge users to put some files and restart the server manually, I think they leave my cms and we are going to lose state!! Because of this problem, I want to try this way.
