ansi-styles

ANSI escape codes for styling strings in the terminal

You probably want the higher-level chalk module for styling your strings.

Install

$ npm install ansi-styles

Usage

const style = require('ansi-styles');

console.log(`${style.green.open}Hello world!${style.green.close}`);


// Color conversion between 16/256/truecolor
// NOTE: If conversion goes to 16 colors or 256 colors, the original color
//       may be degraded to fit that color palette. This means terminals
//       that do not support 16 million colors will best-match the
//       original color.
console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);

Advanced usage

By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.

• style.modifier
• style.color
• style.bgColor

Example

console.log(style.color.green.open);

Raw escape codes (i.e. without the CSI escape prefix \u001B[ and render mode postfix m) are available under style.codes, which returns a Map with the open codes as keys and close codes as values.

Example

console.log(style.codes.get(36));
//=> 39

256 / 16 million (TrueColor) support

ansi-styles uses the color-convert package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.

The following color spaces from color-convert are supported:

• rgb
• hex
• keyword
• hsl
• hsv
• hwb
• ansi
• ansi256

To use these, call the associated conversion function with the intended output, for example:

style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code

style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code

style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
