ansi-colors

Easily add ANSI colors to your text and symbols in the terminal. A faster drop-in replacement for chalk, kleur and turbocolor (without the dependencies and rendering bugs).

Please consider following this project's author, Brian Woodward, and consider starring the project to show your ❤️ and support.

Install

Install with npm:

$ npm install --save ansi-colors

Why use this?

ansi-colors is the fastest Node.js library for terminal styling. A more performant drop-in replacement for chalk, with no dependencies.

• Blazing fast - Fastest terminal styling library in node.js, 10-20x faster than chalk!

• Drop-in replacement for chalk.

• No dependencies (Chalk has 7 dependencies in its tree!)

• Safe - Does not modify the String.prototype like colors.

• Supports nested colors, and does not have the nested styling bug that is present in colorette, chalk, and kleur.

• Supports chained colors.

• Toggle color support on or off.

Usage

const c = require('ansi-colors');

console.log(c.red('This is a red string!'));
console.log(c.green('This is a red string!'));
console.log(c.cyan('This is a cyan string!'));
console.log(c.yellow('This is a yellow string!'));

Chained colors

console.log(c.bold.red('this is a bold red message'));
console.log(c.bold.yellow.italic('this is a bold yellow italicized message'));
console.log(c.green.bold.underline('this is a bold green underlined message'));

Nested colors

console.log(c.yellow(`foo ${c.red.bold('red')} bar ${c.cyan('cyan')} baz`));

Nested styling bug

ansi-colors does not have the nested styling bug found in colorette, chalk, and kleur.

const { bold, red } = require('ansi-styles');
console.log(bold(`foo ${red.dim('bar')} baz`));

const colorette = require('colorette');
console.log(colorette.bold(`foo ${colorette.red(colorette.dim('bar'))} baz`));

const kleur = require('kleur');
console.log(kleur.bold(`foo ${kleur.red.dim('bar')} baz`));

const chalk = require('chalk');
console.log(chalk.bold(`foo ${chalk.red.dim('bar')} baz`));

Results in the following

(sans icons and labels)

Toggle color support

Easily enable/disable colors.

const c = require('ansi-colors');

// disable colors manually
c.enabled = false;

// or use a library to automatically detect support
c.enabled = require('color-support').hasBasic;

console.log(c.red('I will only be colored red if the terminal supports colors'));

Strip ANSI codes

Use the .unstyle method to strip ANSI codes from a string.

console.log(c.unstyle(c.blue.bold('foo bar baz')));
//=> 'foo bar baz'

Available styles
