ANSI escape codes for styling strings in the terminal

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

$ npm install --save ansi-styles

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

console.log(ansi.green.open + 'Hello world!' + ansi.green.close);

Each style has an open and close property.

• reset
• bold
• dim
• italic (not widely supported)
• underline
• inverse
• hidden
• strikethrough (not widely supported)

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white
• gray

• bgBlack
• bgRed
• bgGreen
• bgYellow
• bgBlue
• bgMagenta
• bgCyan
• bgWhite

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.

• ansi.modifiers
• ansi.colors
• ansi.bgColors

console.log(ansi.colors.green.open);
