Turbolinks is no longer being developed. It's been superceeded by Turbo, which is part of Hotwire. In this article, Julio Sampaio shows us how to port our existing Turbolinks apps to Turbo.

In the third and final article of our series on the OWASP Top 10 Web Application Security Risks, we’ll explore the lesser-known risks associated with the development of web applications on Rails when it comes to threats involving security misconfiguration, JSON escaping, etc.

Kubernetes is a popular way to deploy web services and applications using containers. In this, the second of a two-part series, Geshan finishes his step-by-step tutorial for getting up and running with Rails and k8s.

AWS Lambda lets you run your code without worrying about the nuts and bolts of server management or scaling. You might even say it's "serverless." In this article, Jeffrey Morhous shows us how to get started writing Lambda functions in Ruby.

It's not every day that you learn a new approach to error handling for Ruby. In this article, Abiodun walks us through a novel error-handling process called Railway Oriented Programming and shows us how to implement it with dry-rb's monads.

Kubernetes has become very popular in recent years as a way to deploy applications using containers. In this article, Geshan shows us how to get a Rails app up and running inside a local K8s cluster.

Google's Cloud Functions let developers run their code in production in a scalable way without worrying about the minutiae of server administration. In this article, Subomi shows walks us through building a real-world service using GCF.

In this article, Petr Hlavicka will give you a solid foundation of knowledge about multi-factor authentication and will walk you through implementation with Rails, Webauthn, and Devise

Turbo and ActionCable make it a snap to create Rails applications that respond to user behavior in real-time. In this article, Abiodun shows us how to use them together to create a full-featured chat application in Rails.

Google Cloud Platform provides developers with many tools to build scalable apps in a way friendlier than AWS. In this article, Olasubomi Oluwalana shows us how we can use the Google Cloud Engine, Storage, and PubSub offerings to build an uptime monitoring system in Ruby.

Hotwire is a way to build modern web applications without much JavaScript by sending HTML over the wire. In this article, Renata Marques introduces us to Hotwire and walks us through a simple example.

Tailwind CSS is a popular CSS framework that helps developers quickly build and style web pages with a unique utility-based approach. Unlike other CSS frameworks, it comes with its own build tooling. In this article, Jeffery Morhous walks us through setting up Tailwind CSS with Rails and Webpacker.

Vue is a popular front-end that is especially useful for Rails developers since it was designed to be incrementally adoptable. That means you can use Vue for parts of your UI without having to rebuild everything from scratch. In this article, John Emmanual will introduce us to Vue, show us how to set it up in Rails, and walk us through a simple project.

This article is the next in our series about building a toy programming language in Ruby. Alex Braha Stoll shows us how to implement the interpreter for function definitions, variable declarations, and more.

Race conditions are arguably the most insidious kind of bug; they're intermittent, subtle, and most likely to occur in production. ActiveRecord's update_counter provides us with a convenient way to avoid race conditions when incrementing or decrementing values in the database. In this article, Jonathan Miles shows us how to use it, how it's implemented, and other approaches to avoiding race conditions.

Lambda is an excellent option for deploying lower-traffic web services when you don't want to maintain another server and you want easy access to all of AWS's other services. In this article, Godwin Ekuma shows us step-by-step how to deploy our Rails apps to AWS Lambda.

Good docs make happy customers. But documentation is HARD. You have to figure out what's important and write it up in a way that's tailored to your audiences and consistent across the site. Now you need to set up a website, publish the docs and maintain them as your product changes. Fortunately, we have seasoned technical writer Kate Bartolo here to walk us through the whole process.

Rails apps tend to start simple, with clean models and controllers. Then you start adding features. Before you know it, your models and controllers are big, unwieldy, and hard to understand. Refactoring into service objects is a great way to split these big pieces up, so they're easier to understand, test, and maintain.
