The Rails (Edge) Guides got a new facelift today! Read about it on the blog: https://rubyonrails.org/2024/3/20/rails-guides-get-a-facelift

Use this commands for new Rails app:

"rails new myapp --main -d=postgresql -c=tailwind -a=propshaft"

"--main" ensures that I have all the goodies that are not available with Rails 7, and will only be released with Rails 8 (presumably around RailsWorld 2024 in September)

New features:

✅ Built-in PWA (Progressive Web App) support
✅ Default Github CI config
✅ Propshaft - lightweight version of sprockets
✅ Brakeman - security scanner
✅ Rubocop code linter

You can learn more about all the "rails new" options by typing "rails new --help" in your terminal.

Save Time with Custom Rails Generators

Learn to create time-saving reliable custom generators quickly and efficiently.

It's time to quit the copy-paste-search-replace dance.
Duplicate an existing file. Then duplicate the corresponding test file. Open them in your editor. Search and replace throughout both files. Manually update or delete a few more things.

Run the tests. Track down spots the search and replace didn't catch. Fix those issues, and run the tests again. Then you can get back to the real work.
That's no way to do things, and yet, we've all done it far too often.

You already apply and re-use basic patterns on a regular basis. You're just doing it the hard way—either because you didn't know or because you believed custom generators required more effort than they're worth.
