@visionappscz/stylelint-config

VisionApps' collection of shareable configs for Stylelint:

• extends stylelint-config-standard with rules to encourage low specificity and avoid nesting,
• includes additional configs for checking order, SCSS and CSS Modules.

Installation

Install Stylelint and this config:

$ npm install --save-dev stylelint @visionappscz/stylelint-config

Basic Usage

Apply the config in your Stylelint config:

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

👉 To see the rules that this config uses, please read the main config itself.

Optional: Checking Properties Order

To further extend control over coding style of your stylesheets, you can also check for properties order:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@visionappscz/stylelint-config/order"
  ]
}

The order config enforces a consistent order of content in your declaration blocks:

1. Sass variables,
2. CSS custom properties,
3. Sass @extend,
4. single-line Sass @include,
5. declarations,
6. nested rules.

For better flexibility, block at-rules (like @media, @supports, and also Sass @if, @each, etc.) can be placed anywhere in the declaration block.

Furthermore, properties in the declarations must be ordered by following categories:

1. all properties,
2. content,
3. position,
4. appearance,
5. box model,
6. typography,
7. decorations,
8. effects and transforms,
9. interactions,
10. transitions and animations.

👉 To see the order of individual properties this config prescribes, please read the order config itself.

👉 order config is entirely independent on the main config and thus can be listed anywhere in the extends section of your config. However, that's not the case with our other extending configs.

Usage with SCSS

To lint SCSS files (i.e. *.scss, not *.sass), add the scss config that extends stylelint-config-standard-scss, fixes its incompatibilities with our main config, and overrides some rules to better work with complex stylesheets:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@visionappscz/stylelint-config/scss"
  ]
}

⚠️ Please mind the order of extended configurations, scss config must come after the main config.

👉 To see the rules that this config uses, please read the scss config itself.

Usage with CSS Modules

To lint CSS files in project that leverages CSS Modules, drop in the cssModules config that fixes key incompatibilities of CSS Modules syntax with the main config:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@visionappscz/stylelint-config/cssModules"
  ]
}

Or along with SCSS:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@visionappscz/stylelint-config/scss",
    "@visionappscz/stylelint-config/cssModules"
  ]
}

⚠️ Please mind the order of extended configurations, cssModules must come after the main config, or after the scss config, if present.

⚠️ Only essential features of CSS Modules are recognized by this config. Namely, just camelCase notation for class names and :global pseudo selectors are covered. All other features of CSS Modules (like composes, :local, @value, etc.) are considered non-essential as they can be implemented with Sass (which we encourage) and thus are not recognized by this config.

👉 To see the rules that this config uses, please read the cssModules config itself.

ℹ️ There is a popular stylelint-config-css-modules config that recognizes all features of CSS Modules.

Stylistic Rules

Stylistic rules (like indentation etc.) were dropped in Stylelint v16. If you need to enforce them, you can use @stylistic/stylelint-config:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@stylistic/stylelint-config"
  ]
}

Or, if you feel brave enough and don't need granular configuration of the stylistic rules, you can use Prettier.

Full Example

Example of all configs combined:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@visionappscz/stylelint-config/order",
    "@visionappscz/stylelint-config/scss",
    "@visionappscz/stylelint-config/cssModules",
    "@stylistic/stylelint-config"
  ]
}

FAQ

How do I change the indentation?

With Stylistic

If using the @stylistic plugin, just override the @stylistic/indentation rule in your Stylelint config:

{
  "extends": [
    "@visionappscz/stylelint-config",
    "@stylistic/stylelint-config"
  ],
  "rules": {
    "@stylistic/indentation": 2
  }
}

👉 See the @stylistic/stylelint-config documentation for more options.

With Prettier

If using Prettier, you can configure the indentation in your Prettier config:

{
  "tabWidth": 2
}

Or in your .editorconfig:

[*]
indent_size = 2

👉 See Prettier documentation for more options.
