What is Ruby on Rails & Why Is It Useful?

Ruby on Rails (sometimes RoR) is the most popular open source framework for web applications. It is based on the Ruby programming language. With Rails, you can build any application, from simple to complex – and you can work with Rails without limits!

What does Rails actually do?

Rails helps you build websites. These are the websites you use every day. On these sites, you can log in, write comments and reviews, and make purchases. This handy seven-page PDF helps you quickly find the Ruby syntax you need, the Ruby method you’re looking for, or the built-in class whose name you can’t remember.

The paths consist of several parts, which makes them easy to use. You can also think of frameworks as Lego blocks. With a framework, you get ready-made code in the form of Lego bricks that you can combine, assign, and modify to create your own web application, which means you don’t have to start from scratch. Ruby on Rails uses the Model-View-Controller (MVC) architecture that many other web frameworks use – one of the most well-known patterns in development.The MVC pattern divides the code of a web application into three interconnected parts.

  • A model that contains the data structure of the application.
  • The view, which represents the visual part of the web application in the form of a web model.
  • The controller, which connects the data to the view and contains the business logic of the application.

What can Ruby and Rails be used for?

Ruby on Rails is best suited for creating online stores with good and comprehensive navigation and shopping options. Ruby on Rails can also be used to create an effective platform for marketing tools. Using Ruby on Rails is also beneficial for creating social networks.

If you need to create non-standard and complex projects, Ruby on Rails can be a good choice. Ruby on Rails is best for creating SaaS solutions because it has simple build options.

Is RoR the right choice for new projects?

The reason why Rails is so popular, especially among startups, is its rapid development. Time to market is key when creating what is known as a minimum viable product (MVP). You want to release your product quickly, get your first users, and start iterating. Ruby on Rails was developed with all of these needs in mind and is without a doubt the first choice for product launches.

With Rails, prototypes can be built very quickly – many are ready for their first users within weeks. The large number of gems (over 160,000 at the time of writing!) and the intuitive nature of the RR framework makes this possible. If you’ve proven your hypothesis or found another viable business model, you don’t need to switch to another framework; Ruby on Rails is ideal for large projects with complex backends, thousands of users, and lots of features. In my opinion, this solution is a game changer – not only does it open up new development opportunities, but it also increases the security and reliability of our applications.

The changes in Rails 6 also show the importance developers place on testing. Automated testing today often takes more and more time. Although we try to reduce the testing burden, in reality, as the application grows, the testing time increases. Unfortunately, more time for testing means less time for development and more money for continuous integration tools.
