chalk

chalk (GitHub: sindresorhus/chalk, License: MIT) is a clean and focused alternative to colors (GitHub: Marak/colors, License: MIT), which is currently the most popular
string styling module, but it has serious deficiencies like extending
String.prototype which causes all kinds of problems. Although there are other ones, they either do too much or not enough.

1
npm install chalk

Why

  • Doesn’t extend String.prototype
  • Expressive API
  • Clean and focused
  • Auto-detects color support
  • Actively maintained
  • Used by 150+ modules

var chalk = require('chalk');
// style a string
console.log(  chalk.blue('Hello world!')  );
// combine styled and normal strings
console.log(  chalk.blue('Hello'), 'World' + chalk.red('!')  );
// compose multiple styles using the chainable API
console.log(  chalk.blue.bgRed.bold('Hello world!')  );
// nest styles
console.log(  chalk.red('Hello', chalk.underline.bgBlue('world') + '!')  );
// pass in multiple arguments
console.log(  chalk.blue('Hello''World!''Foo''bar''biz''baz')  );
