A Rails Engine is like a mini-application. Think of it as a nested Rails app. By “mounting” the engine in your routes file you are providing access to the mini-application via the specified path.
Rails::Engine allows you to wrap a specific Rails application or subset of functionality and share it with other applications or within a larger packaged application. Every Rails::Application is just an engine, which allows for simple feature and application sharing.
