Recently I got to work on a task that included understanding how to test JavaScript requests with RSpec. One thing that I found missing during my time researching solutions was organized and detailed documentation explaining the solutions based on the version of Rails and RSpec the application runs on.

Ruby on Rails is a popular web application framework that is constantly evolving with new versions being released frequently. While upgrading to a newer Rails version can bring new features, better performance, and security patches/improvements, it can also be a challenging task.

In this blog post, we will discuss 7 common mistakes made while doing Rails upgrades and how to avoid them.

Since 2017 we have been focusing on upgrading Ruby on Rails applications. It’s been quite a fulfilling learning process as we continuously improve our workflow best practices, and internal tooling.

In this article I will go into detail to explain how we determine the best approach to create the roadmap for a successful upgrade project.

Smile.io is the world’s largest rewards program provider. Providing solutions for merchants and e-commerce businesses, its loyalty management software integrates with Shopify, BigCommerce, and Wix to reward customers with points and perks for purchases, referrals, and sharing content.

Does this sound interesting? Come and let’s dig into it.

A race condition is a type of software bug that occurs when multiple threads or processes access a shared resource simultaneously, and the outcome of the execution depends on the timing of these accesses.

When we allow users to upload images, they usually upload files without any optimization for the web. It’s up to us to add some measure to prevent those images from slowing down our app. Luckily, the different gems commonly used to handle user uploads also give us solutions for this problem.

This is the second part of the Optimizing Images series. In the first article we talked about the basic concepts and techniques to optimize raster images, and today we’ll talk about techniques to optimize SVG files.

Imagine this scenario: you open a website on your phone, you see an image loading really really slowly, you wonder what’s going on and download the image to see more details… turns out the image is 3000x3000px with a size of 1.5Mb!

So, let’s talk about different ways to optimize images, common problems, and ways to find these issues early.

As of May 1st, 2023, Heroku will no longer be supporting the Heroku-18 stack. The reason for this deprecation is to maintain synchronization with the Ubuntu Long Term Support releases. If you are currently running your Rails application on this stack, when you navigate to the Heroku dashboard you will notice a warning to upgrade to either Heroku-20 or Heroku-22 before the end of the Heroku-18 stack life on April 30th, 2023.

While Heroku-18 will not be supported, do not be alarmed or concerned that the apps running on this stack will stop working. Heroku has confirmed that all existing applications will not be interrupted and non-build functionality will still be available. However, to maintain access to security updates, technical support and the ability to perform new builds, an upgrade will be necessary and is highly recommended.

You might have extended classes or instances in Rails, but do you know you can also extend Rails associations?

class Account < ActiveRecord::Base
    has_many :people, -> { extending FindOrCreateByNameExtension }
end

In this article I’ll discuss a strategy for different readability: a simple way to split your routes file on a Ruby on Rails project.

Gems are a central part in a Rails application, they help us add new functionality to our apps so we don’t have to reinvent the wheel, but also allows us to extract code to better organize the codebase and to share logic between multiple apps. In many cases, we have custom made gems, and we need to ensure they will work properly with the two Rails versions we run when we use the Dual Boot technique during upgrades. But… How do you dual boot the gems?
