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.

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.

  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

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.

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

> This is an extremely trivial bit of JavaScript, but it is made difficult because it is trying to use a JavaScript

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

He does mention running it on a macbook

Not as simple if you are using any "advanced" PG feature. If you testing simple select statements thats probably fine.
