Ruby on Rails excels on the backend with its convention over configuration and simplicity, while Angular provides a dynamic and user-friendly frontend. Together, they create a seamless full-stack experience.

In this blog, we’ll explore how pairing Ruby on Rails with Angular can be the perfect approach for developers aiming to build high-performance, advanced web applications.

How Rails Works?

Ruby on Rails (RoR) is a web application framework that follows the Model-View-Controller (MVC) architecture, which helps organize application code and promote a clear separation of concerns. Here’s an overview of how Rails works, detailing its components and workflow:

1. Request-Response Cycle

The core of any web application is the request-response cycle. When a user interacts with a web application, a request is sent to the server, which processes it and sends back a response. In Rails, this cycle can be broken down into several key steps:

a. Routing

When a request is received by the server, Rails first checks the routing configuration (defined in config/routes.rb) to determine which controller and action should handle the request. Routes define how URLs correspond to controller actions, allowing Rails to map incoming requests to the appropriate code.

b. Controller

Once the appropriate route is matched, Rails invokes the corresponding controller action. Controllers are responsible for processing incoming requests, interacting with the model, and preparing data to be sent to the view.

2. Models

Models represent the data and business logic of the application. In Rails, models are typically backed by a database and are responsible for data manipulation, validation, and associations. Rails uses Active Record, an Object-Relational Mapping (ORM) system, to interact with the database seamlessly.

3. Views

After the controller processes the request and interacts with the model, it prepares data to be rendered in a view. Views are responsible for presenting the data to the user and are usually written in Embedded Ruby (ERB) or other templating languages. Views can include HTML and Ruby code, making it easy to generate dynamic content.

4. Asset Pipeline

Rails includes an asset pipeline that manages CSS, JavaScript, and image files, optimizing and serving them efficiently. It allows for features like concatenation, minification, and preprocessing (e.g., using Sass for CSS).

5. Middleware

Rails uses middleware to process requests before they reach the application and after the response is generated. Middleware can perform tasks such as handling sessions, logging requests, or managing security features.

6. Database Interaction

Rails automatically generates SQL queries based on Active Record methods, allowing developers to interact with the database without writing raw SQL. The framework supports various databases, including PostgreSQL, MySQL, and SQLite.

7. Testing

Rails promotes a test-driven development (TDD) approach by providing built-in testing frameworks for unit tests, functional tests, and integration tests. Developers can write tests to ensure their code works as expected.

8. Gems and Plugins

Rails has a rich ecosystem of gems (libraries) that can extend its functionality. Gems can be used for various purposes, such as authentication, authorization, payment processing, and more. Developers can easily integrate these gems into their applications to add new features.
