## Highlights - Expressive API - Highly performant - No dependencies - Ability to nest styles - [256/Truecolor color support](#256-and-truecolor-color-support) - Auto-detects color support - Doesn't extend `String.prototype` - Clean and focused - Actively maintained - [Used by ~86,000 packages](https://www.npmjs.com/browse/depended/chalk) as of October 4, 2022 ## Install ```sh npm install chalk ``` **IMPORTANT:** Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now. [Read more.](https://github.com/chalk/chalk/releases/tag/v5.0.0) ## Usage ```js import chalk from 'chalk'; console.log(chalk.blue('Hello world!')); ``` Chalk comes with an easy to use composable API where you just chain and nest the styles you want. ```js import chalk from 'chalk'; const log = console.log; // Combine styled and normal strings log(chalk.blue('Hello') + ' World' + chalk.red('!')); // Compose multiple styles using the chainable API log(chalk.blue.bgRed.bold('Hello world!')); // Pass in multiple arguments log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz')); // Nest styles log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!')); // Nest styles of the same type even (color, underline, background) log(chalk.green( 'I am a green line ' + chalk.blue.underline.bold('with a blue substring') + ' that becomes green again!' )); // ES2015 template literal log(` CPU: ${chalk.red('90%')} RAM: ${chalk.green('40%')} DISK: ${chalk.yellow('70%')} `); // Use RGB colors in terminal emulators that support it. log(chalk.rgb(123, 45, 67).underline('Underlined reddish color')); log(chalk.hex('#DEADED').bold('Bold gray!')); ``` Easily define your own themes: ```js import chalk from 'chalk'; const error = chalk.bold.red; const warning = chalk.hex('#FFA500'); // Orange color console.log(error('Error!')); console.log(warning('Warning!')); ``` Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args): ```js import chalk from 'chalk'; const name = 'Sindre'; console.log(chalk.green('Hello %s'), name); //=> 'Hello Sindre' ``` ## API ### chalk.`
