chalk-string

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'

const addStyles = chalkString()

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

addStyles('invalidStyle', 'input') // Invalid styles throw an error

Install

npm install chalk-string

This package is an ES module and must be loaded using an import or import() statement, not require().
