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.
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.
DynamoDB is a NoSQL database offered by AWS. It can be a great way to avoid adding load to your primary database when you need tens of thousands of reads/writes per second. In this article, Julie Kent walks us through the basics of using DynamoDB with Rails.
The #descendants method is part of Rails. It returns all subclasses that inherit from a given class. In this article, Jonathan Miles shows us how to use this method and how it's implemented. It's a great lesson in the ins and outs of Ruby's object model.
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.
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.
RailsConf videos are up. RubyConf 2021 will be in-person. A REXML CVE. Basecamp fallout. Discussion of testing and containers.
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.
Rbenv, RubyGems, and Bundler work together to give us a lot of control over our code's environment. If you know how they work, you'll be better prepared to troubleshoot any problems you encounter. In this article, Olasubomi walks us through the basics of how these three tools do what they do.
Code is never self-contained. It runs in an environment. Docker lets you define that environment in a simple and portable way. That's why pretty much every automated testing and deployment service works with docker containers. You give them a container, and done! But how do you set up a container to use for testing your Rails app? In this article, we'll show you.
Authentication is at the heart of most web development, yet it is difficult to get right. In this article, Diogo Souza discusses common security problems with authentication systems and how you can resolve them. Even if you never build an authentication system from scratch (you shouldn't), understanding these security concerns will help you make sure whatever authentication system you use is doing its job.
