• デフォルトのsprocketsとimportmap-railsで良さそう
  • CSSはtailwind CSSで、フロントはHotwireを使う
• sprocketsかpropshaftかについては、propshaftはまだベータ版ということでsprocketsにする
• rails new --css=tailwindすれば、tailwindcss-railsgemが入るはず(Node.js不要)

その他のskipオプションは付けない。不要なら後から消せばいい。

You can specify extra command-line arguments to be used every time `rails new` runs in the .railsrc configuration file in your home directory, or in $XDG_CONFIG_HOME/rails/railsrc if XDG_CONFIG_HOME is set. Note that the arguments specified in the .railsrc file don't affect the default values shown above in this help message. You can specify which version to use when creating a new rails application using `rails __ new`. Examples: `rails new ~/Code/Ruby/weblog` This generates a new Rails app in ~/Code/Ruby/weblog. `rails __ new weblog` This generates a new Rails app with the provided version in ./weblog. `rails new weblog --api` This generates a new Rails app in API mode in ./weblog. `rails new weblog --skip-action-mailer` This generates a new Rails app without Action Mailer in ./weblog. Any part of Rails can be skipped during app generation. ```

実行予定のコマンド

• rails new . -d postgresql --skip-test --css=tailwind

[djkazunoko]

rails newしてから1度もrails起動してないことに気づいたので、以下を実行。

1. bin/setupを実行(db/schema.rbが作成された)
2. bin/devを実行して、ブラウザからlocalhost:3000にアクセスできた
3. db/schema.rbを削除

$ bin/setup
== Installing dependencies ==
The Gemfile's dependencies are satisfied

== Preparing database ==
Created database 'nijikaigo_development'
Created database 'nijikaigo_test'

== Removing old logs and tempfiles ==

== Restarting application server ==
