@mnrendra/chalk-ansi-styles

Refactored ansi-styles code to support both CommonJS (CJS) and ES Modules (ESM) with mixed exports. This allows users to import or require the module without needing to access the .default property.

Benefits

✅ Supports both CommonJS (CJS) and ES Modules (ESM)
✅ Mixed exports (no need to access .default for default value)
✅ Minified distribution package
✅ Well-tested (100% code coverage)
✅ TypeScript source code for easier development

Reference

Refactored from the original source code since version v6.2.1, commit 7e35811. This module will be kept updated with the original source code; contributions are welcome. 🙏

Types

import type {
  Layer,
  CSPair,
  Modifier,
  ModifierName,
  ForegroundColor,
  ForegroundColorName,
  BackgroundColor,
  BackgroundColorName,
  StyleNumbers,
  ColorName,
  StyleName,
  Styles,
  AnsiStyles
} from '@mnrendra/chalk-ansi-styles'

The default type is Styles, which only provides the public properties. If you want to expose all defined properties, use AnsiStyles. Examples:

import type { AnsiStyles } from '@mnrendra/chalk-ansi-styles'

import styles, { ansiStyles } from '@mnrendra/chalk-ansi-styles'

console.log(styles.color) // Will show an error:
// Property 'color' does not exist on type 'Styles'.

// To solve the above error, use the `AnsiStyles` type as shown below:
console.log((styles as AnsiStyles).color)

// Or you can import `ansiStyles`, which has the same value as the default export (`styles`),
// but uses the `AnsiStyles` type:
console.log(ansiStyles.color)
