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. Enabling/Disabling Colors The package will auto-detect whether your terminal can use colors and enable/disable accordingly. When colors are disabled, the color functions do nothing. You can override this with a command-line flag: node myapp.js --no-color node myapp.js --color=false node myapp.js --color node myapp.js --color=true node myapp.js --color=always FORCE_COLOR=1 node myapp.js Or in code: var colors = require('colors'); colors.enable(); colors.disable(); 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")); Combining Colors var colors = require('colors'); colors.setTheme({ custom: ['red', 'underline'] }); console.log('test'.custom); Protip: There is a secret undocumented style in colors. If you find the style you can summon him.
