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 with npm:
$ npm install --save ansi-colors
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.
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!'));
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'));
console.log(c.yellow(`foo ${c.red.bold('red')} bar ${c.cyan('cyan')} baz`));
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)
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'));
Use the .unstyle
method to strip ANSI codes from a string.
console.log(c.unstyle(c.blue.bold('foo bar baz')));
//=> 'foo bar baz'
Note that bright and bright-background colors are not always supported.
