@netcentric/stylelint-config

If StyleLint is new to you, you might want to check out what it does and how to configure it.

Install

npm install --save @netcentric/stylelint-config stylelint

Setup

.stylelintrc

Create or update your .stylelintrc file in the folder of your project's package.json:

{
  "extends": "@netcentric/stylelint-config"
}

Please do not add it as a property stylelint within the package.json as it is not supported by all essential IDEs (e.g. Webstorm wouldn't pick it).

Note that Stylelint is different to eslint as it uses cosmiconfig to load the configuration file. Biggest difference: the first config file it finds is used, and it will stop looking for further files in upper folders. That means, you only can define one .stylelintrc file, preferably on the same folder as your project's package.json.

IDE integration

Most IDEs should have an integration for Stylelint.

Build system integration

In your package.json

  "scripts": {
    "lint": "stylelint "\"<root-css-files>/**/*.css\""
  }

Make sure you do not accidently lint files you are not interested that are out of scope for your build; e.g. files within the node_modules folder.

Overwriting rules

Please stick to the Netcentric rules as they are battle tested and were created to form a company wide basis for CSS code quality. If there's a very specific case you want to deactivate a rule for consider using StyleLint inline comments instead.

If there's a rule you consider as outdated or simply wrong please contact the package's maintainer or file an issue in JIRA (bugs in package.json) or create a PR on the package's repository (repository in package.json).

If you have a very project specific case where adding or deactivating a rule makes perfectly sense, you can overwrite any rule using the rules property.

I don't understand why I violated rule X

You can find a description of all rules on the Stylelint Homepage.
