+> Terminal string styling done right
+
+[](https://travis-ci.org/sindresorhus/chalk) [](https://www.youtube.com/watch?v=Sm368W0OsHo)
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
+
+**Chalk is a clean and focused alternative.**
+
+
+
+
+## Why
+
+- Highly performant
+- Doesn't extend `String.prototype`
+- Expressive API
+- Ability to nest styles
+- Clean and focused
+- Auto-detects color support
+- Actively maintained
+- [Used by ~3000 modules](https://www.npmjs.com/browse/depended/chalk)
+
+
+## Install
+
+```
+$ npm install --save chalk
+```
+
+
+## Usage
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+var chalk = require('chalk');
+
+// style a string
+chalk.blue('Hello world!');
+
+// combine styled and normal strings
+chalk.blue('Hello') + 'World' + chalk.red('!');
+
+// compose multiple styles using the chainable API
+chalk.blue.bgRed.bold('Hello world!');
+
+// pass in multiple arguments
+chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz');
+
+// nest styles
+chalk.red('Hello', chalk.underline.bgBlue('world') + '!');
+
+// nest styles of the same type even (color, underline, background)
+chalk.green(
+ 'I am a green line ' +
+ chalk.blue.underline.bold('with a blue substring') +
+ ' that becomes green again!'
+);
+```
+
+Easily define your own themes.
+
+```js
+var chalk = require('chalk');
+var error = chalk.bold.red;
+console.log(error('Error!'));
+```
+
+Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
+
+```js
+var name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> Hello Sindre
+```
