colorette

What is colorette?

The colorette npm package is a Node.js library for colorizing text in the terminal. It provides a simple API to add colors and styles to console output, which can be useful for creating more readable and organized logs, command-line tools, and scripts.

What are colorette's main functionalities?

Text coloring

Colorette allows you to color text output in the terminal. You can use predefined color functions to wrap your text and make it appear in the specified color when logged to the console.

const { red, green, blue } = require('colorette');
console.log(red('This is red text'));
console.log(green('This is green text'));
console.log(blue('This is blue text'));

Text styling

In addition to coloring, colorette provides functions to apply various text styles such as bold, underline, and italic.

const { bold, underline, italic } = require('colorette');
console.log(bold('This is bold text'));
console.log(underline('This is underlined text'));
console.log(italic('This is italic text'));

Combining styles

Colorette allows you to combine multiple styles and colors for a single piece of text. This can be useful for highlighting important information or creating visually distinct messages in the terminal.

const { red, bold, bgGreen } = require('colorette');
console.log(bold(red(bgGreen('Red text on green background'))));

Quickstart

Here's the first example to get you started.

import { blue, bold, underline } from "colorette"

console.log(
  blue("I'm blue"),
  bold(blue("da ba dee")),
  underline(bold(blue("da ba daa")))
)

Here's an example using template literals.

console.log(`
  There's a ${underline(blue("house"))},
  With a ${bold(blue("window"))},
  And a ${blue("corvette")}
  And everything is blue
`)

Of course, you can nest styles without breaking existing color sequences.

console.log(bold(`I'm ${blue(`da ba ${underline("dee")} da ba`)} daa`))

Need to dynamically override color detection? You can do that too.

import { createColors } from "colorette"

const { blue } = createColors({ useColor: false })

console.log(blue("Blue? Nope, nah"))

Installation

npm install colorette

API

blue(text)

See all supported colors.

blue("I'm blue") //=> \x1b[34mI'm blue\x1b[39m

isColorSupported

true if your terminal supports color or false otherwise. Used internally and handled for you, but exposed for convenience.

createColors({ useColor })

Create a reusable instance of Colorette. Color support is automatically detected, but you can override it by setting the useColor boolean property.

import { createColors } from "colorette"

const { blue } = createColors({ useColor: false })

Environment

You can override automatic color detection from the CLI too via NO_COLOR= or FORCE_COLOR=.

$ FORCE_COLOR= node example.js | ./consumer.js
