Validate CSS (and SCSS, Less, SugarSS) to RSCSS conventions
This repository is a maintenance fork of rstacruz/stylelint-rscss. It has been rewritten in TypeScript and is compatible with stylelint v16.
stylelint-rscss is a plugin for stylelint to validate your code against RSCSS conventions. It supports SCSS (Sass), SugarSS and Less, as supported by stylelint.
As a stylelint plugin, it can be used with stylelint's hundreds of rules or other stylelint configs to validate other good CSS practices as well.
Quickstart guide
Install: Install stylelint and stylelint-rscss to your project.
npm install --save-dev stylelint @elecdeer/stylelint-rscss
Configure: Create a .stylelintrc
in your project. Use the stylelint-rscss/config
configuration, which has defaults for strict RSCSS conventions.
// .stylelintrc
{
"extends": [
"@elecdeer/stylelint-rscss/config"
]
}
Add a script: Add an npm script to your package.json
.
// package.json
{
"scripts": {
"lint:css": "stylelint path/to/css/**/*"
}
}
Run it!
npm run lint:css
Recommendations
These steps are not required, but are highly recommended:
- Add stylelint-config-standard as well!
- Configure your text editor to use stylelint. (See text editor support)
- Add
npm run lint:css
to your CI script.
Text editor support
You need to install stylelint globally (npm install -g stylelint
) for text editor support.
npm install -g stylelint
After that, here are the plugins I'd recommend:
- Neovim: neomake (no setup needed)
- Vim: syntastic (use the
stylelint
checker) - Atom: atom-linter + linter-stylelint
Also see stylelint's complimentary tools documentation.
Examples
Here are some valid examples according to RSCSS rules.
.component-name { }
// ✓ Components should be two or more words, separated by dashes.
.component-name > .element { }
// ✓ Elements should be one word. Use `>` to denote markup structure.
.component-name > .element.-foo { }
// ✓ Variant classes begin with a dash (`-`).
.component-name.-variant { }
// ✓ Components can have variants.
._helper { }
// ✓ Helpers start with an underscore (`_`).
Some cases not allowed:
.component-name .element { }
// ✗ Use `>` to denote markup structure.
.component-name.variant { }
// ✗ Variants must begin with a dash.
.componentname { }
// ✗ Components should be two or more words.
.component-name.other-component { }
// ✗ Only one component name is allowed.
.component-name > .-foo { }
.-foo { }
// ✗ Variants should be attached to components or elements.
Also OK:
h2 { }
// ✓ Bare elements can be styled.
.component-name > h2 { }
// ✓ Bare elements can be styled as elements.
.component-name > a:hover[aria-hidden="false"] { }
// ✓ Pseudo-classes and attributes are OK.
.component-name:hover > .element { }
// ✓ They're ok for components too.
