PhpStorm 2021.1 Help

Stylelint

PhpStorm integrates with Stylelint so you can inspect your CSS code from inside the IDE. Stylelint wakes up automatically when you edit a CSS file and highlights the detected problems, see Lint your code below.

Install Stylelint

  • Open the embedded Terminal (Alt+F12) and type:

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

This installs Stylelint and its standard configuration. Learn more from the Stylelint official website.

Activate and configure Stylelint

  1. To activate Stylelint, open the Settings/Preferences dialog Ctrl+Alt+S, go to Languages and Frameworks | Style Sheets | Stylelint, and select the Enable checkbox. After that the controls in the dialog become available.

  2. In the Stylelint Package field, specify the location of the stylelint package installed globally or in the current project. If you followed the standard installation procedure, PhpStorm detects the package automaticaly.

  3. Optionally:

    In the Configuration file field, specify the location of your configuration file.

    By default, the field is empty and PhpStorm uses the Stylelint native mechanism to detect configurations automatically. With this auto-detection mode, Stylelint goes up the folder structure and looks for configurations defined in one of the following ways:

    • Through a stylelint property in a package.json file.

    • In a .stylelintrc.json, .stylelintrc.yaml, .stylelintrc.yml, or .stylelintrc.js file.

    • In a stylelint.config.js file that exports a JavaScript object.

    • In a stylelint.config.cjs file that exports a JavaScript object. When running Stylelint in JavaScript, packages with the "type":"module" property in their package .json.

    Learn more from the Stylelint official website.

    To use a custom configuration file, click the Browse button in the Configuration file field and select the path to the required configuration file in the dialog that opens.

  4. If you want Stylelint to also wake up automatically when you are editing a JavaScript file and check Style Sheet injections in it, select the Process JS files checkbox.

Lint your code

Stylelint wakes up automatically when you edit a Style Sheet file and highlights the detected problems.

To lint Style Sheet injections in JavaScript code, open the Settings/Preferences dialog Ctrl+Alt+S, go to Languages and Frameworks | Style Sheets | Stylelint, and select the Process JS files checkbox.
