What is kleur?

The kleur npm package is a library for formatting terminal text with ANSI colors. It provides a simple and chainable API to style strings that are output to the console with various colors, backgrounds, and text styles.

What are kleur's main functionalities?

Coloring text

This feature allows you to apply text color to your console output. The example shows how to color the text green.

const kleur = require('kleur');
console.log(kleur.green('Hello world!'));

Chaining styles

Kleur supports chaining multiple styles together. In this example, the text 'Error!' is styled to be red, bold, and underlined.

const kleur = require('kleur');
console.log(kleur.red().bold().underline('Error!'));

Background colors

You can also set background colors for your text. Here, the text 'Info' has a blue background with white foreground color.

const kleur = require('kleur');
console.log(kleur.bgBlue().white('Info'));

Conditional styling

Kleur allows conditional styling, where you can enable or disable colors based on certain conditions. In this example, the red color is applied only if the environment is not production.

const kleur = require('kleur');
const enabled = process.env.NODE_ENV !== 'production';
console.log(kleur.enabled(enabled).red('Only styled if not in production'));
