Making the Most of Your Logs in Rails

Most people only realize the necessity of logs when they need them the most. But when your application breaks, user complaints start flooding in, and you have no clue how to fix it, it's too late to add some log messages that might have helped. Good logs pay for themselves tenfold. They make it a breeze to diagnose those tricky bugs, and if you do logs right, they can alert you of issues even before your users notice. But what does it mean to 'do logging right'?


Storing Ephemeral UI State with Kredis for Rails

Kredis (Keyed Redis) is a recent addition to the Rails developer's toolkit. It strives to simplify storing and accessing structured data on Redis. In this first part of a two-part series, we'll start by going into how Kredis works. We'll then run through an example use case for storing ephemeral UI state using a bespoke Redis key. Let's get started!


What's New in Rails 7.1

Rails 7 was a welcome release that brought a lot of significant features and changes. On the backend, Rails 7 introduced asynchronous query loading and Zeitwerk for autoloading. The frontend saw Hotwire becoming the default solution for new Rails apps. Rails 7.1 will add to these notable features. In this post, we'll discuss some noteworthy additions that are likely to be shipped.


A Guide to Rails View Helpers

Views in Rails don't do much besides showcasing what we want. Sure, they might render slightly different results depending on who's watching (an admin or a logged-in user has a different experience than a guest user, for example), but they don't do much processing on what they're given. Or at least they shouldn't. Often though, Rails projects wind up with a lot of logic in their views. In this post, we'll explore how to use Rails helpers to keep our views clean and readable.


Rails ActionCable - the good and the bad

ActionCable allows developers to move away from the typical request/response paradigm of old to one where persistent WebSocket connections are maintained from clients to your Rails servers. Event-driven and low-latency, WebSockets are an excellent choice for use cases like live chat, alerts & notifications, and realtime data broadcast.


Create a Business Language for a Rails Application

As web developers, we tend to approach problems with traditional low-risk solutions. When all you have is a hammer, everything looks like a nail. When you need complex input from the user, you use a form and JSON representation (even if, in retrospect, it is not the most efficient solution). In this post, we'll take a different approach. We'll leverage some tooling to create a business language that extends the functionality of a Rails application. Let's get started!
