colorboy

Easily add color to your console.logs in Node.js.

Installation

npm install colorboy

Usage

require("colorboy").addDefaults();
console.log("Globgogabgalab".red);
console.log("Potato chips".cyan.underline.italic);
console.log("The Eden Project".color("#067CB6").bgColor(25, 25, 150).bold);

Colors

Below you can see how to specify colors. To specify a background color, simply use .bgColor() instead of .color().

• Colors added by addDefaults():

  'Sonic'.cyan

  Can be red, black, green, yellow, blue, pink, cyan, white or gray
• A CSS keyword: 'Sonic'.color('crimson')
• A hex code:

  'Sonic'.color('#FF00FF')

• An rgb code:

  'Sonic'.color(220, 20, 60)

• An rgb code:

  'Sonic'.color(220, 20, 60, 'rgb')

• An hsl code:

  'Sonic'.color(32, 100, 100, 'hsl')

• An hsv code:

  'Sonic'.color(32, 100, 50, 'hsv')

• An hwb code:

  'Sonic'.color(32, 0, 50, 'hwb')

Passing arrays works too:

// the following are equivalent:
'Sonic'.color(220, 20, 60)
'Sonic'.color([220, 20, 60])
 
// the following are equivalent:
'Sonic'.color(32, 100, 100, 'hsl')
'Sonic'.color([32, 100, 100, 'hsl'])

Styles

Use styles added by addDefaults():

'Sonic'.bold

Can be bold, dim, italic, underline, inverse and strikethrough

When specifying custom styles, you can pass a string or an array of strings. These are the possible strings:

• "bold"
• "dim"
• "italic"
• "underline"
• "inverse"
• "strikethrough"
• "reset"
• "hidden"
• "visible"

Custom colors & styles

let currentBgColor = 'red';
 
require('./index.js')
  .addColor("crimson", {color:"crimson"})
  .addColor('greenish', {
    color: '#000000',
    bgColor: '#00FE7C',
    style: ['bold', 'italic'],
  })
  .addColorFunction('error', (color) => {
    return {
      color: color,
      bgColor: currentBgColor,
    }
  })
console.log('Custom:');
console.log('Unlike Pluto'.greenish);
console.log('Unlike Pluto'.error('white'));
currentBgColor = 'cyan'
console.log('Unlike Pluto'.error('black'));

colorboy.addDefaults(functions = true, colors = true, styles = true)

colorboy.addColor(name, options)

Adds a color prototype.

• name: The prototype name
• options: A color object (see below)

colorboy.addColorFunction(name, optionsCallback)

• name: The prototype name.

color object

An object that defines colors and styles, in this format:

}
