ansi-colors

Contributing

> 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 :heart: 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

Note that bright and bright-background colors are not always supported.
