I think the htmx counterpart from Rails folks would be Turbo not Stimulus

Such a weird take. Of course "self hosting" means "self hosting".

Sure it could be easier/safer to manage, everything can be better.

Over the last couple of years hosting it I had a single issue with an upgrade but that was because I simply ignore the upgrade instructions and YOLOed the docker compose update.

Again, is it perfect? No. Would I expect a non tech savy user to manage their own instance? Again no.

I like Hotwire but I admit its a bit confusing to get started with and the docs dont help. Form submits + redirects are a bit weird, you cant really make the server "break out" of a frame during a redirect if the form was submitted from inside a frame (there are workarounds, see https://github.com/hotwired/turbo/issues/257).

Also, custom actions [https://turbo.hotwired.dev/handbook/streams#custom-actions] are super powerfull, we use it to emmit browser events, update dom classes and attributes and so on, just be careful not to overuse it.

Felt a similar way when playing Expedition 33 earlier this year. Such a great game.

Maybe worth mentioning that ruby has a very similar feature https://bundler.io/guides/bundler_in_a_single_file_ruby_scri...

So... train tracks?

Not that I think this is pratical or even looks good, but its also doable with rails

  require 'bundler/inline'

  gemfile(true) do
    source 'https://rubygems.org'

    gem 'rails', '~> 7.1'
    gem "sqlite3", "~> 1.4"
  end

  require 'rails'
  require 'active_record/railtie'
  database = 'app_development.sqlite3'

  ENV['DATABASE_URL'] = "sqlite3:#{database}"
  ActiveRecord::Base.establish_connection(adapter: 'sqlite3', database: database)
  ActiveRecord::Schema.define do
    create_table :my_table, force: true do |t|
      t.integer :my_table_id
    end
  end

  class App < Rails::Application
    routes.append do
      root to: 'home#index'
    end
  end

  class HomeController < ActionController::Base
    def index
      render inline: 'HOME'
    end
  end

  App.initialize!

  run App

For very small apps on ruby land sinatra and roda are the right choices. On python the choice would be flask instead of the single file django.

Is the db mandatory in Rails or could the db specific lines be removed from the code if no db is needed?

Not mandatory, you could remove that

Cool. What would be the steps from a fresh Debian to get it running and see it in action?

Not sure debian has (a modern) ruby installed by default, but I think you only need to have a working ruby installation and running the script. On a sidenote, this came out recently and could interest you https://dashbit.co/blog/announcing-phoenix-playground

I tried it like this:

    1: apt install ruby
    2: Put your code in test.rb
    3: ruby test.rb

I then I got:

    Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
    \e[0m
        current directory: /var/lib/gems/3.1.0/gems/stringio-3.1.1/ext/stringio
    /usr/bin/ruby3.1 -I /usr/lib/ruby/vendor_ruby -r ./siteconf20240626-4044-iylnuy.rb extconf.rb
    mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

    You might have to install separate package for the ruby development
    environment, ruby-dev or ruby-devel for example.

So I tried:

    4: apt install ruby-dev
    5: ruby test.rb

Then I got:

    [4147, #<Thread:0x00007f9a4af6bc60 run>, #<NameError: uninitialized constant Gem::Source
    (defined?(@source) && @source) || Gem::Source::Installed.new
                                         ^^^^^^^^

He seems a bit biased maybe? Its fair that a rails controller does not exactly screams what its doing (implicit view rendering, routing etc).

But then, for someone not deep into react, a magic string like "use server" also does not clarify anything.

Also, he argues that just because you can it does not mean you should scatter sql queries around your views. But again, just because you can do a bunch of implicit stuff on a Rails controller it does not mean you should.

I belive you are thinking about Niobium and not Graphene

> Could be, but TFA doesn't specify it

If I understood correctly it does. They are handling promo codes outside of stripe.

I feel like you are missing the point of the article

Yes, it is trivial javascript, and it was trivially solved by a couple of javascript lines
