> 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](https://github.com/doowb), and consider starring the project to show your :heart: and support.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ 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](https://github.com/chalk/chalk).
* _No dependencies_ (Chalk has 7 dependencies in its tree!)

* _Safe_ - Does not modify the `String.prototype` like [colors](https://github.com/Marak/colors.js).
* Supports [nested colors](#nested-colors), **and does not have the [nested styling bug](#nested-styling-bug) that is present in [colorette](https://github.com/jorgebucaran/colorette), [chalk](https://github.com/chalk/chalk), and [kleur](https://github.com/lukeed/kleur)**.
* Supports [chained colors](#chained-colors).
* [Toggle color support](#toggle-color-support) on or off.

## Usage

```js
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

```js
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

```js
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](https://github.com/jorgebucaran/colorette), [chalk](https://github.com/chalk/chalk), and [kleur](https://github.com/lukeed/kleur).

```js
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.

```js
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.

```js
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.

### Style modifiers

* dim
* **bold**

* hidden
* _italic_

* underline
* inverse
* ~~strikethrough~~

* reset

## Aliases

Create custom aliases for styles.

```js
const colors = require('ansi-colors');

colors.alias('primary', colors.yellow);
colors.alias('secondary', colors.bold);

console.log(colors.primary.secondary('Foo'));
```

## Themes

A theme is an object of custom aliases.

```js
const colors = require('ansi-colors');

colors.theme({
  danger: colors.red,
  dark: colors.dim.gray,
  disabled: colors.gray,
  em: colors.italic,
  heading: colors.bold.underline,
  info: colors.cyan,
  muted: colors.dim,
  primary: colors.blue,
  strong: colors.bold,
  success: colors.green,
  underline: colors.underline,
  warning: colors.yellow
});

// Now, we can use our custom styles alongside the built-in styles!
console.log(colors.danger.strong.em('Error!'));
console.log(colors.warning('Heads up!'));
console.log(colors.info('Did you know...'));
console.log(colors.success.bold('It worked!'));
```
