Introduction Migrating a legacy application to Ruby on Rails 7 can be challenging, but it offers massive improvements in performance, security, and maintainability. With Hotwire, Turbo, and eschewing Webpacker in favor of import maps, Rails 7 brings modern development practices to the framework. In this guide, we’ll cover: ✅ Why migrate to Rail... Read More

Introduction In web applications, certain tasks can be slow and should not be executed in real-time—like sending emails, processing large files, or making API calls. Rails provides background job processing to handle these tasks asynchronously, improving performance and user experience. In this guide, we’ll cover: ✅ Why you need background jobs... Read More

Introduction Performance is crucial for modern web applications, and asset management plays a key role in reducing load times and improving user experience. Rails provides the Asset Pipeline, a powerful tool that helps developers: Organize and minify assets (CSS, JavaScript, images) Reduce HTTP requests for faster page loads Enable effic... Read More

Introduction Relational databases like PostgreSQL and MySQL are commonly used with Ruby on Rails. However, as applications grow, NoSQL databases offer greater scalability, flexibility, and performance improvements for handling large-scale data and high concurrency. This guide explores how to integrate NoSQL databases with Rails, covering MongoD... Read More

Introduction Security is a critical aspect of web application development. As Rails applications handle sensitive user data, they become attractive targets for hackers. Failure to implement proper security measures can lead to data breaches, account takeovers, and application compromise. In this guide, we will explore advanced security strategi... Read More

Introduction As a Ruby on Rails application grows, so does its complexity. Without a solid testing strategy, development can become slow and error-prone. A well-tested codebase ensures: Code Reliability: Catch bugs before they reach production. Scalability: Make large-scale refactors with confidence. Developer Productivity: Reduce time s... Read More

Introduction Docker and Kubernetes have revolutionized application deployment and scalability. By containerizing Ruby on Rails applications with Docker and deploying them on Kubernetes, we can achieve: Scalability: Easily scale services up or down based on demand. Portability: Run the same containerized app in development, testing, and pro... Read More

Introduction Multi-tenancy is a crucial architectural pattern for SaaS applications where multiple users or organizations (tenants) share the same Rails application while maintaining data isolation. Implementing it correctly ensures scalability, security, and maintainability. This guide explores schema-based and row-based multi-tenancy in Rails... Read More
