ansi-rainbow

Rainbowify string with https://github.com/sindresorhus/ansi-styles

Install

npm install ansi-rainbow

Basic example

 
var rainbow = require('ansi-rainbow')
 
console.log(rainbow.r("I am in the pony world"))
//or
console.log(rainbow.r("I", "am", "in", "the", "pony", "world"))
 
//what about background rainbows?
 
console.log(rainbow.bg("I am a background in the pony world"))

That outputs:

Features

Rainbow is skipping black and white colors (did you ever seen these on a rainbow?). But, we could imagine that in a world where Pony's are flying, black could be part of a rainbow so:

rainbow.add('black white') //adds black and white

Let's write all features together to print a rainbow flag \o/:

 
rainbow
    .add('black', 'white')
    .reset() //we do not want black and white anymore - note it does not reset options only colors
    .skip(rainbow._backgrounds) //skips backgrounds
    .add('bgBlue bgMagenta bgCyan') //this will keep order when rainbowified
    .options({color_space: true, gap: 3}) //this will force color spaces and change color every 3 characters
 
    console.log(rainbow.bg('         '))
    console.log(rainbow.bg('123456789'))
    console.log(rainbow.bg('         '))
 

That outputs:
