Ruby on Rails is well known for its very easy and fast implementation of web functionalities in any of the authentication, searching, testing, API services, sending emails, cropping images, scrapping-etc and that makes possible by using gems.
As we know that Rails is an open-source web framework and due to that so many developers have made lots of contributions in terms of making gems so that anyone can make use of them.
When we talk about the top 10 people in this world then automatically it means the top 10 famous people in the world in the same way when we are talking about the top 10 ruby gems it means the gems which are well known and very popular to all the ruby developers.
So based on the total number of downloads we can figure out the top 10 ruby gems which are given below
Selenium-webdriver: Do you want to test your web application with testers that make your business profitable by not paying extra salary to testers then go with these gems. Currently, I am using these gems and it is very useful especially for testing purposes. This gem provides an automated testing tool so we can test every single feature of our web application.
Exception_notifications: I love this gem because automatically the developer/web administrator get email notifications if something goes wrong or breaks any feature on the production server with every single detail. So it is mandatory to install this gem on the production server.
Capistrano: How you will deploy the code on the server? You need to first SSH to your server then pull the code run migrations, background task so many things manually you have to do. Is it possible to run a single command which performs a task for deployment? Capistrano makes it possible. From your local, you can do everything on the server.
Devise: I think no web application exists without authentication and for that, we used this gem. Using devices the authentication can be integrated within a few hours which takes days without it. From signup, sign in, forgot password, update account to Devise also used in API authentication token.
Activeadmin: Great gem for admin GUI. Making the admin panel is really fun using this gem. It is easy to integrate with lots of customization.
Jbuilder: As we can say nowadays apps are replacing the web application so we need to make the implementation of APIs very efficient and Jbuilder does this. It helps back end developers to make the JSON response in any format very efficiently.
Elasticsearch: Search is a very common feature of web applications and the elastic search engine is a very famous search engine based on the Lucene library. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. This gem is a wrapper for Elasticsearch.
Delayed job: Background processing is very important to any web application to give the immediate response to the user and is actually the process is running in the background like when a user does sign up then immediately we can give the response to the user that “We have sent a confirmation link into your email” but actually the email sending process running in the background.
Figaro: Every web application store configuration parameters also called environment variables and for that, we used this gem. It creates yml files to store the confidential parameters.
Simple form: Makes the form implementation with lots of customization and powerful components become fun by using this gem.
Apart from the above gems, there are also various gems widely used. I will keep updating this document for, especially Rails beginners 🙂
