Using plug-ins with Ruby on Rails is really not hard. In fact, it is quite easy to use plug-ins because it already has a very well developed plug-in. This means that plug-ins can be easily installed and used in the application. It is not unusual for a developer to use up to six plug-ins for every single Rails application.
Plug-ins are quite helpful because during the process of development, the plug-ins already have the code that you need ready. You won’t even have to write it yourself. This is one reason why developing on Rails is so fast and easy.
