Display your Progressive Web App’s Offline Ability
Your progressive web app works offline, but do your users know that? You can use a Stimulus controller to manage your service worker, show the caching status, and hint to your user that the webpage will work offline.
Introducing Mailbox Tester
Do you send lots of emails with your Rails app, and wish you had a way to spot check them? Fix those typos, and make sure the dynamic content looks correct? It’s easy to verify there are no code bugs with Rail’s builtin Mailer preview. But how do you prevent sending someone’s wrong order or […]
Testing Tables in ActionText Using System Test
So you’ve built a fascinating, interactive addition to your ActionText page. How do you test that interactivity? You can use System Test, a feature built into Rails to run apps and test them in a web browser. This simulates real usage, especially since the browser supports CSS and Javascript.

Adding Tables to ActionText With Stimulus.js
First, I’d like to thank Chris Oliver for his wonderful Railsconf 2020.2 talk, Advanced ActionText: Attaching any model in rich text. I’d highly recommend you watching that first for context, as I’m going to implement this ActionText table based on his Youtube preview. Towards the end of the video, Chris mentions you could use the […]
Radio Selection Unselect with Stimulus.js
Radio buttons, modeled after physical buttons on old radios, allow for only one element in a list to be selected. The browser automatically unselects the other options. This simple behavior often fits your needs, but I recently found myself wanting to be alerted on an unselect action so that I could change what was displayed […]
Using CSS in Rails 6
I’ve been finally moving some of my Rails applications from Rails 5.2 to Rails 6 and I always seem to get caught up on the webpacker CSS locations. It’s not uncommon to spend a lot of time figuring out where the CSS went, and why it’s not being served. Pre-webpacker, there were two sprockets directives […]

HNPWA With Rails + Stimulus.js
Sometimes you want a development side project that will push you. A project that is non trivial, and provides lots of opportunities to build a complicated, data hungry application. Here is an example of such a project that rivals any complicated website in performance, and interactivity, built entirely in Ruby on Rails and Stimulus.js
Convert your jQuery snippet to a Stimulus controller
Getting started with Stimulus can be as easy as converting a small jQuery snippet into a Stimulus controller. Here are three conventions that will make the conversion really quick. This assumes you’ve setup Stimulus already. ’turbolinks:load’ to connect() Any setup that the jQuery snippet does when the page is loaded can be moved to the […]
