Reverse routing for live routes: given a path can I get the module that's responsible for it?

Given live routes like these:

live "/projects/:id/config", ProjectsLive.Config
live "/projects/:id/config/calendar", ProjectsLive.Config.Calendar
live "/projects/:id/config/maintenance", ProjectsLive.Config.Tickets
live "/projects/:id/config/vendors", ProjectsLive.Config.Vendors

is there a way I can get the module name if I know the url path? Rails has this method: Rails.application.routes.recognize_path

Do you need it at runtime? If not, mix phx.routes works

3

Yes, I want it at runtime to return the user to a path that I save as a last known location.

May this help?
