About SASS to Stylus

Convert SASS to Stylus syntax. Part of the DevTools Surf developer suite. Browse more tools in the CSS collection.

Use Cases

• Node.js developers converting Sass files for Stylus-based projects
• Teams migrating to Stylus for its more powerful built-in functions
• Developers switching from Sass to Stylus for Express.js middleware support
• Projects consolidating on Stylus for a unified Node.js toolchain

Tips

• Both are indentation-based, so check nesting depth is correct
• Verify that Sass's = and + become standard Stylus function calls
• Check that Sass string operations convert to Stylus equivalents

Fun Facts

• Sass and Stylus are the only two major CSS preprocessors that support indentation-based syntax as their primary form.
• Stylus was partially inspired by Sass, but TJ Holowaychuk added features like postfix conditionals that Sass lacks.
• Both Sass and Stylus support operator overloading for color and unit arithmetic, unlike LESS.

FAQ

Is Sass to Stylus common?

Very uncommon. Mostly used for code comparisons or porting small utility files into a legacy Stylus codebase.

How do @mixins convert?

Sass @mixin becomes a Stylus function. Calling syntax changes: @include becomes direct invocation.

Do variables carry values?

Yes. The $ prefix is the same; default values (`!default` in Sass) become Stylus's `= default`.

Should I use this for production?

Not advised. If you're on Sass/SCSS today, stay there — Stylus is effectively retired.
