     Key security practices in Rails involve using 'strong parameters' to prevent mass-assignment vulnerabilities and implementing CSRF tokens in forms. It also focuses on robust user authentication and authorization, often using gems like Devise. Regularly updating Rails and its dependencies and using HTTPS for data transmission is essential for maintaining security.

5. What is New in Ruby on Rails Development

   Ruby on Rails, which was just about quick prototyping, is now about creating scalable and secure apps. The framework transforms and embraces innovations that optimize performance, security, developer productivity, and user experiences.

   Let's look at the key transformations in Ruby on Rails development for 2025 and beyond:

   • Rails 7.1 - Enhancing Productivity

     Rails 7.1 is a landmark release, and the improvements make the framework more capable of creating applications today. Here are some of its key features:

     • ActiveRecord Encryption: Developers can now securely support encrypting database columns without third-party libraries at the application level.

     • Multi-Database Sharding: This feature enables data sharding across several databases and high-traffic websites. As a result, these become easier to scale without interfering with legacy issues.

     • Enhanced Concurrency: With better thread safety and native asynchronous queries, Rails applications are becoming smarter and smarter.

     • Simplified Asset Management: Propshaft's new asset pipeline addition, which has a lighter setup and quicker build time, is popularly used in place of Webpacker.

   • Hotwire and Turbo

     Front-end Ruby on Rails developers use Hotwire, mainly Turbo Frames and Turbo Streams, to deliver interactivity, mitigate the dependency on JavaScript, and create high-performance apps. This reduces the need to work with complex front-end libraries like React or Vue.

     • Turbo Frames help update only a section of a page without refreshing the entire page, resulting in much faster, more responsive user experiences.
     • Turbo Streams supports live browser updates using WebSockets or Server-Sent Events, minimizing the usage of custom JavaScript.
   • Performance, Speed, and Security to the Core

     Security and performance are fundamentals of Rails applications now. Here are some trending features:

     • Improved for Core Web Vitals: Ruby on Rails developers make web pages better for Google's Core Web Vitals, like Largest Contentful Paint and First Input Delay. This enhances SEO and user experience.

     • Secure by Default: Rails 7.1 has tighter security defaults like Content Security Policies, SameSite cookies to secure sessions, and encrypted credentials.

     • Dynamic Rate Limiting: Rails applications can now use high-level throttling techniques to ensure thorough protection against threats and convenience to legitimate users.

   • CI/CD Automation - The Norm

     CI/CD deployment has now become integral in automating development workflows in 2025. Here are some of its features:

     • GitHub Actions: Developers use GitHub Actions to review and test code quality without inconvenience.

     • CircleCI and Semaphore CI: Teams with larger or more complex pipelines deploy them as they leverage parallelism, artifact cache, Docker integration, and cleaner integrations.

     • Automated Deployment Tools: Some tools include Capistrano and Hatchbox, which support easier deployment, less downtime risk, and faster releases.

     Integrating CI/CD tools guarantees better code quality, shorter delivery cycles, and better-equipped development teams.

   • AI-Based Development

     Artificial intelligence is helping Rails developers to code more wisely and efficiently. Trending features include:

     • GitHub Copilot: Functions as an AI collaborator that offers suggestions for code and helps developers learn how to refactor code

     • Amazon CodeWhisperer: Helps developers code more secure cloud applications and maintain compliance, using real-time suggestions and security best practices

     • Smarter Refactoring: AI identifies programming patterns and recommends smart refactoring and clean code steps

   • Internationalization (i18n) and Accessibility (a11y)

     Ruby on Rails developers focus on internationalization and accessibility, maintaining legal compliance, and enhancing user experiences. Here are some of its features:

     • Improved i18n Support: Mobility, now part of Rails' built-in I18n system, enables developers to build multilingual global applications with translations.

     • Accessibility First: Developers follow WCAG 2.2 standards and write apps using semantic HTML, the correct ARIA roles, and full keyboard navigation support.

     • Cultural Localization: Apps automatically adapt to users' local currency, date format, language, and regulatory needs.

     Modern Rails developers do more than write code; they also build inclusive and accessible digital experiences that follow the W3C WCAG 2.2 Guidelines.
