sort-named-exports

💼 This rule is enabled in the following configs: recommended-alphabetical, recommended-line-length, recommended-natural.

🔧 This rule is automatically fixable by the --fix CLI option.

📖 Rule Details

Enforce sorted named exports.

Maintaining a consistent and sorted order of named exports can improve code readability.

💡 Examples

Alphabetical and Natural Sorting

// ❌ Incorrect
export {
  defineConfig,
  validateConfig,
  merge,
  baseConfig,
} from './config'

// ✅ Correct
export {
  baseConfig,
  defineConfig,
  merge,
  validateConfig,
} from './config'

Sorting by Line Length

// ❌ Incorrect
export {
  defineConfig,
  validateConfig,
  merge,
  baseConfig,
} from './config'

// ✅ Correct
export {
  validateConfig,
  defineConfig,
  baseConfig,
  merge,
} from './config'

🔧 Options

This rule accepts an options object with the following properties:

interface Options {
  type?: 'alphabetical' | 'natural' | 'line-length'
  order?: 'asc' | 'desc'
  'ignore-case'?: boolean
}

type

_{(default: 'alphabetical')}

• alphabetical - sort alphabetically.
• natural - sort in natural order.
• line-length - sort by code line length.

order

_{(default: 'asc')}

• asc - enforce properties to be in ascending order.
• desc - enforce properties to be in descending order.

ignore-case

_{(default: false)}

Only affects alphabetical and natural sorting. When true the rule ignores the case-sensitivity of the order.
