Question 1

How do I use glob imports in sass-rails?

Accepted Answer

In your Sass/SCSS files, use syntax like @import 'mixins/*' to import all files in a directory using Ruby glob patterns. This is sorted alphabetically, but avoid it for files with styles to prevent cascade ordering problems, as noted in the README.

Question 2

sass-rails vs using plain Sass gem in Rails?

Accepted Answer

sass-rails integrates seamlessly with Rails' asset pipeline, providing asset helpers and configuration via config.sass, while plain Sass requires manual setup and lacks Rails-specific features like glob imports. It's the official choice for native integration.

Question 3

Why does sass-rails warn against Sprockets require directives?

Accepted Answer

Sprockets directives like require are primitive and don't work well with Sass files. sass-rails uses native Sass @import for better functionality and integration, as explicitly stated in the README to avoid issues.

Question 4

How to change the default syntax from SCSS to Sass in sass-rails?

Accepted Answer

Set config.sass.preferred_syntax = :sass in your Rails configuration file. This changes the syntax used by Rails generators and defaults, but note that existing file extensions (.scss or .sass) still determine syntax during compilation.

Question 5

Can I use sass-rails with Rails 7 and import maps?

Accepted Answer

sass-rails works with Rails' asset pipeline, which includes Sprockets. In Rails 7, import maps are for JavaScript, but for CSS, sass-rails remains compatible, though newer alternatives like cssbundling-rails might suit different front-end setups.

Question 6

What's the difference between sass-rails and cssbundling-rails?

Accepted Answer

sass-rails is integrated with Sprockets and the asset pipeline, offering Rails-native features, while cssbundling-rails uses Node.js-based tools like Sass via Bun or npm for compilation, providing more modern build processes but less seamless Rails integration.
