The lighter-colors module is a lightweight terminal color utility.
From your project directory, install and save as a dependency:
npm install --save lighter-colorsUpon requiring lighter-colors, the String prototype is modified so that all
strings have access to color properties which output color versions of
themselves:
require('lighter-colors')
console.log('Error'.red)
console.log('Warning'.yellow)
console.log('Confirmation'.green)If you would like to disable color, you can use a --no-color argument, use
the disable method:
var colors = require('lighter-colors')
colors.disable()
console.log('This will be colorless.'.magenta)
colors.enable()
console.log('This will become magenta.'.magenta)Here's the full list of exported colors:
{
reset: '\u001b[0m',
base: '\u001b[39m',
bgBase: '\u001b[49m',
bold: '\u001b[1m',
normal: '\u001b[2m',
italic: '\u001b[3m',
underline: '\u001b[4m',
inverse: '\u001b[7m',
hidden: '\u001b[8m',
strike: '\u001b[9m',
black: '\u001b[30m',
red: '\u001b[31m',
green: '\u001b[32m',
yellow: '\u001b[33m',
blue: '\u001b[34m',
magenta: '\u001b[35m',
cyan: '\u001b[36m',
white: '\u001b[37m',
gray: '\u001b[90m',
bgBlack: '\u001b[40m',
bgRed: '\u001b[41m',
bgGreen: '\u001b[42m',
bgYellow: '\u001b[43m',
bgBlue: '\u001b[44m',
bgMagenta: '\u001b[45m',
bgCyan: '\u001b[46m',
bgWhite: '\u001b[47m'
}In addition to the getter properties for the colors in the list above, there's
also a plain getter property which removes colors from a colorful string:
require('lighter-colors')
var colorful = 'Blue'.blue
var colorless = colorful.plainAnd if you would like to use the color sequences without invoking getter
properties, lighter-colors exports them for you:
var colors = require('lighter-colors')
var red = colors.red
var white = colors.white
var blue = colors.blue
var base = colors.base
console.log(red + 'Red' + white + 'White' + blue + 'Blue' + base)
