\n\n---\n\n \n\n## Highlights\n\n- Expressive API\n- Highly performant\n- Ability to nest styles\n- [256/Truecolor color support](#256-and-truecolor-color-support)\n- Auto-detects color support\n- Doesn't extend `String.prototype`\n- Clean and focused\n- Actively maintained\n- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020\n\n## Install\n\n```console\n$ npm install chalk\n```\n\n## Usage\n\n```js\nconst chalk = require('chalk');\n\nconsole.log(chalk.blue('Hello world!'));\n```\n\nChalk comes with an easy to use composable API where you just chain and nest the styles you want.\n\n```js\nconst chalk = require('chalk');\nconst log = console.log;\n\n// Combine styled and normal strings\nlog(chalk.blue('Hello') + ' World' + chalk.red('!'));\n\n// Compose multiple styles using the chainable API\nlog(chalk.blue.bgRed.bold('Hello world!'));\n\n// Pass in multiple arguments\nlog(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));\n\n// Nest styles\nlog(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));\n\n// Nest styles of the same type even (color, underline, background)\nlog(chalk.green(\n\t'I am a green line ' +\n\tchalk.blue.underline.bold('with a blue substring') +\n\t' that becomes green again!'\n));\n\n// ES2015 template literal\nlog(`\nCPU: ${chalk.red('90%')}\nRAM: ${chalk.green('40%')}\nDISK: ${chalk.yellow('70%')}\n`);\n\n// ES2015 tagged template literal\nlog(chalk`\nCPU: {red ${cpu.totalPercent}%}\nRAM: {green ${ram.used / ram.total * 100}%}\nDISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}\n`);\n\n// Use RGB colors in terminal emulators that support it.\nlog(chalk.keyword('orange')('Yay for orange colored text!'));\nlog(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));\nlog(chalk.hex('#DEADED').bold('Bold gray!'));\n```\n\nEasily define your own themes:\n\n```js\nconst chalk = require('chalk');\n\nconst error = chalk.bold.red;\nconst warning = chalk.keyword('orange');\n\nconsole.log(error('Error!'));\nconsole.log(warning('Warning!'));\n```\n\nTake advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):\n\n```js\nconst name = 'Sindre';\nconsole.log(chalk.green('Hello %s'), name);\n//=> 'Hello Sindre'\n```\n\n## API\n\n### chalk.`
