What is Ruby On Rails?

Ruby on Rails (known as Rails) is a full-stack web application framework written in the Ruby programming language. It streamlines the development process by providing a structured foundation and pre-built components for both the server-side (back-end) and client-side (front-end) of a web application.

Originally created by David Heinemeier Hansson in 2004, Rails gained popularity for its focus on developer productivity and its "convention over configuration" approach, which reduces the need for repetitive coding.

Core Features of Ruby on Rails

Ruby on Rails boasts a collection of features that contribute to its efficiency and developer-friendly nature. Here's a breakdown of some key features:

Convention over Configuration (CoC)

This core principle encourages consistent coding practices and reduces the need for excessive configuration. Rails enforces pre-defined conventions for tasks like naming files and structuring code, saving developers time and effort.

Model-View-Controller (MVC) Architecture

Rails adheres to the MVC architecture, which separates an application into three distinct layers:

• Model: Represents the data and business logic of the application.

• View: Handles the presentation layer, defining how data is displayed to the user.

• Controller: Acts as the intermediary between the Model and View, handling user requests and manipulating data as needed. This separation of concerns promotes clean code, easier maintenance, and better testability.

Built-in Libraries (Gems)

Rails comes bundled with a vast ecosystem of pre-written code modules called "gems". These gems provide functionalities for various tasks like authentication, database interaction, image processing, and more. This extensive library collection eliminates the need to reinvent the wheel and empowers developers to integrate desired features quickly.

Active Record

This powerful component acts as an Object-Relational Mapper (ORM). It bridges the gap between Ruby objects and relational databases, allowing developers to interact with databases using intuitive Ruby syntax. Active Record simplifies data access, manipulation, and migration, streamlining database interactions.

Automatic Testing

Rails encourages a test-driven development (TDD) approach by providing built-in tools for writing unit and integration tests. These automated tests ensure code quality, catch errors early on, and facilitate future code changes with confidence.
