Ruby gems are pieces of software on a Rails app to do things. The following examples are gems:

 

  • Devise lets you make/create users. It can also let you have authentication in your apps.

 

 

  • Kaminari lets you paginate things so they don’t overflow the page.

 

 

  • Can can can lets users have certain permissions to do certain things or visit certain pages.

 

The gem in Ruby is a library. The word “Gem” reminds me of something precious. In some of the books I read, I have come across gemstones. How precious these stones are! Ruby gem allows authentication. Authentication includes logging into an app and creating new accounts. Ruby gem is a perfect fit.
