Learn Stimulus in Ruby on Rails by Building a Toggle)

Hey HN!

For those new to Rails, Stimulus (https://stimulus.hotwired.dev/) is a way to sprinkle frontend javascript code into your Rails views.

I held off using Stimulus in my Rails apps for a long time because I didn't understand it — the data= attributes looked weird, and the connection between my Rails views and Stimulus javascript controllers was confusing.

So I decided to write the guide I wish I had when I was learning Stimulus.

Hope you enjoy it! I'm happy to answer any questions, feel free to ask any.

Thanks, Harrison

Great write-up!

I appreciate that you went the extra mile by showing how a generic enough controller can be used for various use cases.

People coming a from traditional JS background tend to make very specific Stimulus controllers, but when you make them a bit more abstract and modular they become more usable and easier to maintain.

Thank you! I agree - I've seen other articles creating very specific controllers, which gets you into the issue of having heaps of specific controllers which could just be 1.

Glad you found the article useful!

It's not weird. It's just a different way of triggering javascript without using much javascript. Just use jQuery or pure javascript and stop having to learn new, not necessarily better, ways to do the same thing. Which is the main problem with Rails. They hide so much from the developer. Even hide the table id in the schema. It's as if a developer can't handle a extra line or something.

That's because they can't handle it. I've seen a number of systems with 200-300+ tables that grew over 10+ years with 20+ developers working on it. This wasn't a Rails app btw, it's using a framework with much less opinions in a different language where an ORM wasn't being used.

You end up with `id` in some tables or `tablename_id` such as `post_id` as the primary key. It makes interacting with the app feel like a surprise depending on what section of the code base you're working on.
