Options

Options shared by the:

You can use some of these options in the configuration object.

allowEmptyInput​

CLI flag: --allow-empty-input, --aei

Stylelint does not throw an error when glob pattern matches no files.

configFile​

CLI flag: --config, -c

Path to a JSON, YAML, or JS file that contains your configuration object.

Use this option if you don't want Stylelint to search for a configuration file.

The path should be either absolute or relative to the directory that your process is running from (process.cwd()).

configBasedir​

CLI flag: --config-basedir

Absolute path to the directory that relative paths defining "extends", "plugins", and "customSyntax" are relative to. Only necessary if these values are relative paths.

fix​

CLI flag: --fix

Automatically fix, where possible, problems reported by rules.

For CSS with standard syntax, Stylelint uses postcss-safe-parser to fix syntax errors.

When using the Node.js API, the autofixed code is available as the value of the code property in the returned object.

When a rule relies on the deprecated context.fix and a source contains:

  • a scoped disable comment, e.g. /* stylelint-disable color-named */, any problems reported by the scoped rule will not be automatically fixed anywhere in the source
  • an unscoped disable comment, i.e. /* stylelint-disable */, the entirety of the source will not be automatically fixed for that rule

customSyntax​

CLI flag: --custom-syntax

Specify a custom syntax to use on your code.

There are many styling languages, ranging from CSS language extensions like SCSS to entirely different notations, e.g. CSS-in-JS objects.

These styling languages can be embedded within other languages too. For example:

  • HTML <style> tags
  • markdown fences
  • JavaScript template literals

This option allows Stylelint to transform these into something that resembles CSS, which is the language that:

  • underpins all the other styling languages
  • is best understood by rules built into Stylelint

This option should be a string that resolves to a JS module that exports a PostCSS-compatible syntax. The string can be a module name (like my-module) or a path to a JS file (like path/to/my-module.js).

If you want to lint two or more different languages, you can combine customSyntax with the overrides configuration property.

Using the Node.js API, the customSyntax option can also accept a Syntax object. Stylelint treats the parse property as a required value. Also, Stylelint supports syntax modules written in ESM.

note

Stylelint can provide no guarantee that core rules work with custom syntaxes.

formatter​

CLI flags: --formatter, -f | --custom-formatter

Specify the formatter to format your results.

Options are:

  • compact - generates output similar to ESLint's compact formatter
  • github - generates messages via workflow commands for GitHub Actions (DEPRECATED)
  • json (default for Node API) - generates JSON that can be consumed by another tool
  • string (default for CLI) - generates human-readable strings
  • tap - generates Test Anything Protocol output
  • unix - generates messages like a C compiler, so that tools like Emacs' Compilation mode can hyperlink them
  • verbose - extends string to include a list of checked files and a tally for each rule

The formatter Node.js API option can also accept a function or a Promise function, whereas the --custom-formatter CLI flag accepts a path (either a filesystem path or a dependency) to a JS file exporting one. The function in both cases must fit the signature described in the Developer Guide.

cache​

CLI flag: --cache

Store the results of processed files so that Stylelint only operates on the changed ones. By default, the cache is stored in ./.stylelintcache in process.cwd().

The following values are used as cache keys:

  • Stylelint version
  • Options

Enabling this option can dramatically improve Stylelint's speed because only changed files are linted.

warning

Plugins version and implementation are not used as cache keys. We recommend that you delete the cache when updating plugins.

If you run Stylelint with cache and then run Stylelint without cache, Stylelint deletes the .stylelintcache because we have to assume that the second command invalidated .stylelintcache.

cacheLocation​

CLI flag: --cache-location

Path to a file or directory for the cache location.

If a directory is specified, Stylelint creates a cache file inside the specified folder. The name of the file is based on the hash of process.cwd() (e.g. .cache_hashOfCWD) so that Stylelint can reuse a single location for a variety of caches from different projects.

If the directory of cacheLocation does not exist, make sure you add a trailing / on *nix systems or \ on Windows. Otherwise, Stylelint assumes the path to be a file.

cacheStrategy​

CLI flag: --cache-strategy

Strategy for the cache to use for detecting changed files. Can be either "metadata" or "content".

The "content" strategy can be useful in cases where the modification time of your files changes even if their contents have not. For example, this can happen during git operations like "git clone" because git does not track file modification time.

maxWarnings​

CLI flags: --max-warnings, --mw

Set a limit to the number of warnings accepted.

It is useful when setting defaultSeverity to "warning" and expecting the process to fail on warnings (e.g. CI build).

If the number of warnings exceeds this value, the:

  • CLI process exits with code 2
  • Node.js API adds a maxWarningsExceeded property to the returned data

disableDefaultIgnores​

CLI flags: --disable-default-ignores, --di

Disable the default ignores. Stylelint will not automatically ignore the contents of node_modules.

globbyOptions​

CLI flags: --globby-options, --go

Options passed to globby. More info.

ignorePath​

CLI flags: --ignore-path, -i

Path to a file containing patterns that describe files to ignore. The path can be absolute or relative to process.cwd(). You can repeat the option to provide multiple paths. By default, Stylelint looks for .stylelintignore in process.cwd().

ignoreDisables​

CLI flags: --ignore-disables, --id

Ignore stylelint-disable (e.g. /* stylelint-disable block-no-empty */) comments.

You can use this option to see what your linting results would be like without those exceptions.

reportDescriptionlessDisables​

CLI flags: --report-descriptionless-disables, --rdd

Report stylelint-disable comments without a description.

The following patterns are reported:

/* stylelint-disable */
a {}
/* stylelint-disable-next-line block-no-empty */
a {}

But, the following patterns (stylelint-disable -- <description>) are not reported:

/* stylelint-disable -- This problem is ignorable. */
a {}
/* stylelint-disable-next-line block-no-empty -- This problem is ignorable. */
a {}

reportInvalidScopeDisables​

CLI flags: --report-invalid-scope-disables, --risd

Report stylelint-disable comments that don't match rules that are specified in the configuration object.

reportNeedlessDisables​

CLI flags: --report-needless-disables, --rd

Report stylelint-disable comments that don't actually match any lints that need to be disabled.

validate​

CLI flags: --validate, --no-validate

Force enable/disable the validation of the rules' options. Default: true. For example, your CI might be faster by skipping the validation if rules didn't change. e.g.

export default {
  // …
  validate: process.env["CI"] !== "true"
};

codeFilename​

CLI flag: --stdin-filename

A filename to assign the input.

If using code or stdin to pass a source string directly, you can use codeFilename to associate that code with a particular filename.

quiet​

CLI flag: --quiet

Only register problems for rules with an "error"-level severity (ignore "warning"-level).

quietDeprecationWarnings​

CLI flag: --quiet-deprecation-warnings

Ignore deprecation warnings.
