UI Styling Standard ESLint Plugin

The UI Styling Standard is a set of principles to guide styling UI code across Atlassian's frontend codebases and ecosystem.

These are the current ESLint rules that enforce and help comply with the UI Styling Standard today, but more are planned to support the standard over time.

Installation

You must use the recommended config to follow the styling standards at Atlassian, which will ensure compatability and performance with the design system.

module.exports = {
  extends: [
+    'plugin:@atlaskit/ui-styling-standard/recommended',
  ],
};

We don't recommended maintaining your own configuration. If you do not use our config you will need to specify individual rules and configuration. Add the plugin to your eslint.config.cjs file and enable individual rules as you're ready to adopt.

module.exports = {
  plugins: [
+    '@atlaskit/ui-styling-standard',
  ],
  rules: [
+    '@atlaskit/ui-styling-standard/convert-props-syntax': 'warn',
+    '@atlaskit/design-system/local-cx-xcss': 'error',
  ],
};

Rules

Rule	Description	Recommended	Fixable	Suggestions
atlaskit-theme	Ban certain usages of @atlaskit/theme that @compiled/react does not understand	Yes
convert-props-syntax	Convert props syntax that is unsupported by styled-components@<4 or @emotion/styled to props syntax that is supported.
