ANSI escape codes for styling strings in the terminal
You probably want the higher-level chalk module for styling your strings.
$ npm install ansi-styles
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);
Each style has an open
and close
property.

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