Ruby on Rails is considered as one of the greatest frameworks for web development.

And еhere's a reason for that. Rails framework has a clear and standardized syntax, great community and lots of libraries and tools.

What are ‘Gems’ in Ruby on Rails

Ruby on Rails gems are tools and libraries created inside the RoR community by Rails developers. These gems help developers to implement various features with less code and time.

The greatest thing about the RoR gems is that all the tools and libraries are absolutely free for commercial use: the only thing you need to do is to find a suitable solution. The widest selection of Ruby gems designed for both routine and highly specialized tasks is stored in the github.com and rubygems.org repositories.

The interesting point is that the whole Ruby on Rails community is open and active, so we have more and more new gems created with each day. What are the most trending Rails gems in 2020? We’ll talk about them below.

This gem allows you to sign in multiple models at a time

2. Brakeman
