Managing and maintaining stylesheets can become daunting especially for large files.

The following is a script i use to lint my stylesheets.

This helps maintain an uniform coding standard across my stylesheets.

Installation

npm install --save-dev stylelint stylelint-config-standard

This will install the node package stylelint for running the actual lint check.

Additionally to get you started, the stylelint-config-standard is installed which is a set of rules with which the stylelint uses.

Configuration

Now that you’ve installed the necessary packages, you’ll want to configure you project to reference these packakges

These next steps will create your own lint config for your project

touch .stylelintrc.json

This will create an empty file called .stylelintrc.json. This file will be used when deciding on what rules to check against when running the lint.

echo '{
  "extends": "stylelint-config-standard"
}' > .stylelintrc.json

This will add the following text to this newly created file

{
  "extends": "stylelint-config-standard"
}

Since we don’t have any rules yet, it’s helpful to inherit a set of rules from somewhere to get started.

This text basically states that your own rules should inherit from the stylelint-config-standard we installed earlier.

Everything you’ve read up until here is taken from Stylelint GitHub Documentation.

At this point we can run the following script to run lint checks on our *.css files

node_modules/.bin/stylelint "**/*.css"

But that’s not really ideal…

Creating the script alias

Now that you’ve installed and configured stylelint, we’ll want an easy to reference way to run our lint checks

In your package.json, add this new config to the scripts

"scripts": {
    "lint": "stylelint '**/*.css'"
}

Now you can simply run

npm run lint
