rails
Rails is a command line tool and a web application framework written in the Ruby programming language. It is designed to make it easier to build web applications by providing a set of conventions for code organization and structure. The tool allows developers to quickly generate the basic components of a Rails application, such as models, views, and controllers.
Rails follows the Model-View-Controller (MVC) architectural pattern, making it easier to separate different aspects of an application and maintain clean code. It includes a powerful ORM (Object Relational Mapping) called ActiveRecord, which simplifies database queries and interactions.
The command line tool provides many useful features, including generating migrations for database schema changes, running built-in web servers for local development, and generating skeleton code for different aspects of an application.
Rails also comes with a wide range of built-in tools and libraries known as "gems" that extend its functionality. These gems cover various aspects such as authentication, testing, and deployment, allowing developers to quickly add commonly needed features to their applications.
One of the key strengths of Rails is its focus on developer productivity and ease of use. It encourages the use of conventions over configuration, which means developers can spend less time on tedious and repetitive tasks and more time on the core business logic of their applications.
Rails has a large and active community of developers, which means there are many resources available for learning and troubleshooting. The official Rails website provides comprehensive documentation and guides, and there are numerous online tutorials, forums, and books available for further learning.
Overall, Rails is a powerful command line tool and framework that simplifies web application development, providing a solid foundation and a wealth of tools and resources to build robust and scalable applications.
