color-map-rainbow

Create rainbow of colors with minimal dependency.

Inspired from color-rainbow

createRainbow(shades)

import { createRainbow } from 'color-map-rainbow'
import { rgbHex, rgbaString } from 'color-map'

// rainbow = array of [r,g,b,a=1]
const rainbow = createRainbow(72)

// transparentRainbow = array of [r,g,b, 0...0.8]
const transparentRainbow = createRainbow(72, [0, 0.8])

// use `color-map` conversion function to get
// '#000000' or 'rgba(...)`
const hexRainbow = rainbow.map(c => rgbHex(c))
const rgbaRainbow = rainbow.map(c => rgbaString(c))

NPM Commands

There are a few useful commands you can use during development.

# Run tests (and lint) automatically whenever you save a file.
npm run watch

# Run tests with coverage stats (but won't fail you if coverage does not meet criteria)
npm run test

# Manually verify the project.
# This will be ran during 'npm preversion' so you normally don't need to run this yourself.
npm run verify

# Build the project.
# You normally don't need to do this.
npm run build

# Run tslint
# You normally don't need to do this as `npm run watch` and `npm version` will automatically run lint for you.
npm run lint
