Chalk with style strings.

Chalk adds styles to terminal strings. chalk-string is a thin wrapper around it which allows specifying those styles as a string. This enables user-defined or dynamic styling.

Example

import chalkString from 'chalk-string'

chalkString('red')('input') // Same as: chalk.red('input')
chalkString('red bold')('input') // Same as: chalk.red.bold('input')
chalkString('hex-ffffff')('input') // Same as: chalk.hex('ffffff')('input')
chalkString('rgb-10-20-30')('input') // Same as: chalk.rgb(10, 20, 30)('input')

chalkString('invalidStyle')('input') // Invalid styles throw an error

Install

npm install chalk-string

This package works in Node.js >=18.18.0.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.
