$ npm install stylelint-scss
A collection of SCSS-specific linting rules for Stylelint (in a form of a plugin).
Stylelint by itself supports SCSS syntax very well (as well as other preprocessors' syntaxes). Moreover, it introduces some specific rules that can be used to lint SCSS, e.g. to limit nesting
, control the way @-rules
are written. Yet Stylelint is in general focused on standard CSS.
stylelint-scss introduces rules specific to SCSS syntax. That said, the rules from this plugin can be used with other syntaxes, like Less or some PostCSS syntaxes. That's why the rules' names are not tied to SCSS only (at-function-pattern
instead of scss-function-pattern
).
The plugin follows Stylelint's guidelines (about rule names, testing and so on).
This plugin is used in the stylelint-config-standard-scss shared config. We recommend using that shared config, rather than installing this plugin directly.
However, the plugin can still be used in you're crafting a config from the ground up. First, install stylelint-scss
(and stylelint
, if you haven't done so yet) via npm:
npm install stylelint stylelint-scss
Create the .stylelintrc.json
config file (or open the existing one), add stylelint-scss
to the plugins array and the rules you need to the rules list. All rules from stylelint-scss need to be namespaced with scss
.
{
"plugins": ["stylelint-scss"],
"rules": {
// recommended rules
"at-rule-no-unknown": null,
"scss/at-rule-no-unknown": true,
// ...
// any other rules you'd want to change e.g.
"scss/dollar-variable-pattern": "^foo",
"scss/selector-no-redundant-nesting-selector": true
}
}
Please refer to Stylelint docs for detailed info on using this linter.
Here are stylelint-scss' rules, grouped by the thing they apply to (just like in Stylelint).
Please also see the example configs for special cases.

commands.The work on the plugin's rules is still in progress, so if you feel like it, you're welcome to help out with any of these (the plugin follows Stylelint guidelines so most of this is based on its docs):
We communicate via issues and pull requests.
There is also StackOverflow, which would be the preferred QA forum.
