Copy my VS Code settings here: https://blog.corsego.com/vscode-cursor-extensions-rails

The extensions I use in every app:
esbenp.prettier-vscode, - lint CSS and JS
bradlc.vscode-tailwindcss, - Tailwind CSS lookup
heybourn.headwind, - order Tailwind styles
eamodio.gitlens, - Git change lookup
Shopify.ruby-lsp, - Ruby parser
elia.erb-formatter, - erb identation
marcoroth.stimulus-lsp, stimulus autocomplete and
rubocop.vscode-rubocop, - ruby linter

In settings.json I define the rules for each of the extensions.
