slim-rails provides Slim generators for Rails:

• Any time you generate a controller or scaffold, you'll get Slim templates (instead of ERB)
• When your Rails application loads, Slim will be loaded and initialized automatically
• Slim templates will be respected by the view template cache digestor

To use it, add this line to your Gemfile:

gem "slim-rails"

And that's it.

Every time you generate a controller or scaffold, you'll get Slim templates.

If you have existing .erb templates, check out our guide How to convert your .erb templates to .slim on how to achieve this.

This gem is tested with Ruby on Rails 5.2+.

slim-rails was based on haml-rails and it does basically the same thing.

From the version 0.2.0, there is no need to include gem "slim" in your Gemfile.
