   .
5. Streamlined Deployment: Rails 8 also introduces Kamal, a deployment solution aimed at reducing dependency on large cloud providers. The new GitHub CI integration helps streamline deployment processes, adding a default workflow for code quality checks, testing, and vulnerability scanning

What are the Key Features of Ruby on Rails 8?

1. Enhanced Performance with TurboPack Integration

Rails 8 introduces TurboPack, an evolution of the popular Hotwire framework, aimed at speeding up both server-side and client-side performance. TurboPack provides a more seamless experience when building Single Page Applications (SPAs) without needing complex frontend frameworks. It integrates deeply with Rails to offer enhanced caching, faster load times, and smoother page transitions. This update empowers developers to build responsive and dynamic user interfaces directly within Rails.

 TurboPack Integration

• Benefit: Improved performance for both server-side and client-side interactions.
• What’s New: TurboPack is the latest enhancement to the Hotwire framework, optimizing page loading times, reducing the need for heavy JavaScript frameworks, and enabling faster, more interactive web applications.

2. Native Support for Server-Side Components

With Rails 8, we see the introduction of server-side components. Inspired by the success of the ViewComponent library, this new feature allows developers to create reusable, encapsulated UI elements that render directly on the server. Server-side components in Rails 8 are designed to improve code reusability and maintainability while reducing the complexity of frontend JavaScript code.

Server-Side Components

• Benefit: Simplified frontend and UI development.
• What’s New: This feature allows developers to build reusable, encapsulated components that render server-side, reducing the complexity of client-side code and improving maintainability.

3. Improved Active Record Performance

Active Record, the ORM (Object-Relational Mapping) layer of Rails, has received significant performance improvements in version 8. The new batch processing capabilities allow for better handling of large datasets and more efficient database queries. Rails 8 introduces advanced query caching and optimizations that reduce database load, leading to faster data retrieval and processing.

Enhanced Active Record

• Benefit: Faster data processing and improved query handling.
• What’s New: Active Record has received updates like batch processing and more efficient query caching, allowing for better performance when working with large datasets and complex queries.

4. Enhanced Asynchronous Capabilities

Rails 8 expands its asynchronous processing features, making it easier to handle background jobs and real-time updates. The framework now offers improved integration with Active Job et Câble d'action. This enhancement allows developers to create real-time features like live notifications and chat applications with minimal effort, enhancing the interactivity and responsiveness of their apps.

Improved Asynchronous Capabilities

• Benefit: Enhanced handling of real-time features and background tasks.
• What’s New: Rails 8 offers better support for asynchronous programming, making it easier to implement real-time features like live notifications, chat applications, and data streaming using Rails’ ActionCable.

5. Stronger Security Features

Security is a top priority in Rails 8, with several new features designed to protect against common web vulnerabilities. The framework includes improved protection against Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), et SQL Injection attacks. Enhanced encryption mechanisms and updated libraries also make it easier to secure user data and maintain compliance with privacy regulations.

Benefit: Enhanced protection against web vulnerabilities.

What’s New: Rails 8 includes updates to its security mechanisms, offering better protection against SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and other common threats. The framework also features more robust encryption and authentication tools.

6. Streamlined API-Only Mode

API-only mode has become a popular choice for building backend services that interact with modern JavaScript frameworks like React and Angular. Rails 8 offers a streamlined experience for developers building API-only applications, with improved tools for RESTful API development, JSON serialization, and error handling. These enhancements make it simpler and faster to set up a robust API backend.

Benefit: Streamlined development of API-first applications.

What’s New: Rails 8 has improved its API-only mode, making it easier to build and manage RESTful APIs. It offers better tools for JSON serialization, error handling, and faster API responses, making it a solid choice for backend services and microservices.

7. Hotwire and Turbo Ready by Default

Hotwire, the framework for building interactive applications without much JavaScript, is now fully integrated and ready by default in Rails 8. Turbo et Stimulus are set up out of the box, making it easier for developers to create rich user experiences with less client-side code. This change simplifies the process of adding interactivity and enhances performance by relying on server-rendered HTML.

Benefit: Increased productivity and ease of use.

What’s New: Updates to the Rails command-line interface (CLI) provide better error messages, auto-suggestions, and interactive debugging tools. The improved integration with Hotwire also speeds up frontend development, reducing the time needed to build interactive features.
