Ruby on Rails is currently in major version 7.1 and rolling towards Rails 8, the next comprehensive new release. Before Rails 8, though, there’s a significant version that will help bridge the gap: Ruby on Rails 7.2. In this post, we’ll dive into several noteworthy changes in Ruby on Rails 7.2, focusing on the support for database changes in Active Record. You'll come away with hands-on opportunities to work with these features. Let's get started!

DynamoDB is a fully managed NoSQL database service provided by AWS. It is highly available, scalable, and a great fit for applications that need to handle large amounts of data with low latency. DynamoDB is a key-value document database, meaning that it is schema-less and can store any kind of data. It is also a serverless service, so you don’t have to worry about managing and scaling servers. In this take, we will model data in DynamoDB using TypeScript.

Do you write Elixir but sometimes miss the benefits of type safety we have in other languages? If the answer is "yes", you may want to take a look at Gleam. It is a relatively young language that runs on top of the BEAM platform, which means it can be added as an enhancement to an Elixir codebase without you having to rewrite everything. In this article, we will add Gleam code to an Elixir project.

The inclusion of a stable test runner in Node.js(version 18+) has generated significant debate in the community, given the abundance of established third-party testing frameworks. While its arrival naturally sparks comparisons to existing tools, this article won't focus on justifying its place in the ecosystem. Instead, we'll embark on a hands-on exploration of the test runner's core capabilities, from writing and executing tests to organization and customization features.

From custom-made to plug-and-play forms of authentication, Ruby developers have plenty to choose from these days. Yet, as you may know, building your own solution can be costly and dangerous. If Devise is the de facto standard for most teams, an alternative might simplify the lives of most. This article will cover the setup and use of Auth0 in a Ruby on Rails application, including everything you need to get going properly, from handling roles to relying on multiple providers to authenticate users.

Debugging is a valuable skill for any software engineer to have. Unfortunately, most software engineers are not trained in it. And that's not just specific to developers going through boot camps; even in universities, we are not often taught and trained to use a debugger. My teachers and mentors were more interested in getting me to write programs rather than debugging them. If we are fortunate, debugging comes at the end of the semester, in a short, last session.
