By popular demand, colors now ships with two types of usages!

The super nifty way

var colors = require('colors');

console.log('hello'.green); // outputs green text console.log('i like cake and pies'.underline.red) // outputs red underlined text console.log('inverse the color'.inverse); // inverses the color console.log('OMG Rainbows!'.rainbow); // rainbow console.log('Run the trap'.trap); // Drops the bass

or a slightly less nifty way which doesn't extend String.prototype

var colors = require('colors/safe');

console.log(colors.green('hello')); // outputs green text console.log(colors.red.underline('i like cake and pies')) // outputs red underlined text console.log(colors.inverse('inverse the color')); // inverses the color console.log(colors.rainbow('OMG Rainbows!')); // rainbow console.log(colors.trap('Run the trap')); // Drops the bass

I prefer the first way. Some people seem to be afraid of extending String.prototype and prefer the second way.

If you are writing good code you will never have an issue with the first approach. If you really don't want to touch String.prototype, the second usage will not touch String native object.

Disabling Colors

To disable colors you can pass the following arguments in the command line to your application:

node myapp.js --no-color Console.log string substitution

var name = 'Marak'; console.log(colors.green('Hello %s'), name); // outputs -> 'Hello Marak' Custom themes

Using standard API

var colors = require('colors');

colors.setTheme({ silly: 'rainbow', input: 'grey', verbose: 'cyan', prompt: 'grey', info: 'green', data: 'grey', help: 'cyan', warn: 'yellow', debug: 'blue', error: 'red' });

// outputs red text console.log("this is an error".error);

// outputs yellow text console.log("this is a warning".warn); Using string safe API var colors = require('colors/safe');

// set single property var error = colors.red; error('this is red');

// set theme colors.setTheme({ silly: 'rainbow', input: 'grey', verbose: 'cyan', prompt: 'grey', info: 'green', data: 'grey', help: 'cyan', warn: 'yellow', debug: 'blue', error: 'red' });

// outputs red text console.log(colors.error("this is an error"));

// outputs yellow text console.log(colors.warn("this is a warning"));
