Are you still having fun when you code? Have you ever wanted to make a game with Ruby? @matheusrich.bsky.social is here to reignite that fire in you!

Nice addition in Rails: now when validates_uniqueness_of fails, you'll be able to access the ID of the record that caused the conflict github.com/rails/rails/...

Just deleted ~1.6k LOC and ~770 KB of JS by replacing a chart library (and all of its deps) with a Ruby helper that renders the charts as plain HTML/CSS. CSS Anchor Positioning made this basically JS-free.

Inspired by @nateberkopec.bsky.social, I wrote about why and how you should enable MFA for your gems! If you don't have any gems, this can be one of the easiest open-source contributions you can make! Check it out: thoughtbot.com/blog/lets-en...

No one sets out to write a slow test, and yet it happens. Prevent slow tests from creeping into your test suite again! Tests are not enough, we need *fast* tests! thoughtbot.com/blog/introdu...

Here's one of those things that are easy to miss on code review and will make your tests super slow. Good news: it's easy to fix! thoughtbot.com/blog/combine...

TIL about Rails' image_submit_tag api.rubyonrails.org/v8.1.2/class...

This was a fun one to write!

Today I learned about Rails' Time.days_in_month and Time.days_in_year. So handy!

🎉 end_of_life 1.0.0.alpha is released! It includes: - Macos install via homebrew - Support for scanning EOL Node.js versions - Support for detecting versions from `mise.toml`. - A new `check` command to check if specific product releases are EOL - A revamped CLI Stay updated!

TIL about Git LFS: An open source Git extension for versioning large files git-lfs.com

Just shaved 200-250ms from a CLI app by just requiring dependencies only when they're needed. It might not seem much, but it really matters to get that snappy feel.

This is my favorite 404 page

Did you know that Rails 7.1 stops receiving security updates in 3 weeks? Wished that you had a tool that would inform you about this kind of stuff? Well, end_of_life v0.5 was just released and it now supports Rails! Check it out: github.com/MatheusRich/...

I've hacked the first version of end_of_life in a weekend. I had limited time, so I decided to only support Ruby. It served me well for years, but I thought it was time to expand support for other tools (Rails, Node, Python, databases, etc).

If you wanna use Rails 8.1 today, you can check if there's anything new in the dotfiles, Dockerfile, or the generated authentication system using rails-diff: github.com/MatheusRich/...

The amount of event listeners LLMs suggest when writing Stimulus controllers makes me think most people are not making the most out of Stimulus targets.

TIL about the Zen browser. Looks cool! zen-browser.app

Join me at @thoughtbot.com’s Open Summit this year! I’m extremely excited to be part of this event. Even better, it’s *free* and *online*, so I hope I can see you there! timriley.info/posts/join-m...

This is exciting!

I remember a time where GitHub had a team dedicated to fixing small user pain points. Now everyone complains about it being slow and adding AI features. What a change.

TIL about `ActiveRecord.to_param`. I've always defined `#to_param` manually ``` class User < ActiveRecord::Base to_param :name end user = User.find_by(name: 'Fancy Pants') user.id # => 123 user_path(user) # => "/users/123-fancy-pants" ```

I forgot to share, but about a month ago I got my first commit into Crystal! You can use this if you're on Crystal >= 1.17

How hard can extracting an emoji from a string be? Well..

Rails now has a `credentials:fetch` command. This is useful to extract a credential and add to Kamal secrets, for example: KAMAL_REGISTRY_PASSWORD=$(rails credentials:fetch kamal.registry_password) No need to use rails runner just for that anymore! github.com/rails/rails/...

Hey, I'm on This Week in Rails world.hey.com/this.week.in...

TIL you can download an .epub version of the Rails guides! guides.rubyonrails.org/epub/ruby_on...

Ever wondered how Ruby works under the hood? No need to take a compilers class to get that! You can watch my #RailsConf talk to understand the basics. Along the way you might even write your first programming language. www.youtube.com/watch?v=ozay...

I feel like half of my web problems would be solved if 1. styling select fields was widely available, and 2. select multiple=true had a good default experience (select on click + search + better styles)

🎉 rails-diff v0.6.0 is released! This version includes: - a `--only` option to only include specific files or directories in the diff - a new `dotfiles` command to compare dotfiles (configuration files like .rubocop.yml) Enjoy! rubygems.org/gems/rails-d...

All the talks from the final RailsConf are now posted! www.youtube.com/playlist?lis...

I just made an app test suite 3x faster by just using rack test instead of selenium on every system test that didn't need JS interactions!

I *think* I found a bug on Stimulus (or Chrome?). When clicking on a autocomplete suggestion, it triggers an action even if it doesn't match the KeyboardEvent filters. Reproduction here: codepen.io/matheusrich/...

In Rails 8.1, when you get an error you will be able to click the line number and it will open your editor on that exact spot! PR: github.com/rails/rails/...

CSS might get an if function soon: developer.chrome.com/blog/if-arti... ``` button { aspect-ratio: 1; width: if(media(any-pointer: fine): 30px; else: 44px); } ```

I've used AI to write so many useful little scripts for me. It is such a time saver!

Do we really need to manually invalidate Russian doll caches on many-to-many relationships on Rails? This doesn't seem right. evrim.io/invalidating...

Rails (via @fxn.bsky.social) just added support for marking associations as deprecated: ``` has_many :posts, deprecated: true ``` With that, Active Record will report any usage of the posts association. There are three reporting models: warn, raise, and notify. github.com/rails/rails/...

I'd love if Rails had e2e encryption (built-in). Has anyone build something like that before?

TIL about the name_of_person gem. Pretty cool! github.com/basecamp/nam...

If you're building a PWA with Rails don't forget to ensure that you're rendering valid JSON on routes like /manifest.json. I've added a test for that:

accent-color is so easy and useful. CSS gets better everyday!

The Ruby dev iceberg

So now that I have a Bluesky account I have to check X, Mastodon and Bluesky to follow Ruby-related stuff. I'm glad @shortruby.com exists, but still... I'm almost building my own stuff that joins it all.

There has been a push towards fixtures for a while, but this global shared state is hurting me. It's hard to know which records are available for any given test, or if I should just modify a particular record for the current test. You change one thing, it breaks a test elsewhere.
