Installation

npm install javascript-color-gradient

or

yarn add javascript-color-gradient

Usage

Using two color gradients

import Gradient from "javascript-color-gradient";

const colorGradient = new Gradient();

const color1 = "#3F2CAF";
const color2 = "#8BC2E3";

colorGradient.setGradient(color1, color2);

Or more:

import Gradient from "javascript-color-gradient";

const colorGradient = new Gradient();

const color1 = "#3F2CAF";
const color2 = "#e9446a";
const color3 = "#edc988";
const color4 = "#607D8B";

colorGradient.setMidpoint(20);

colorGradient.setGradient(color1, color2, color3, color4);

Methods

To set two or more hex color values. Should always be defined.

setGradient(color1, color2);

To set the number range to n. By default n is 10.

setMidpoint(n);

To return an array of hex colors. Requires no parameters.

getArray();

To return certain hex color corresponding to the number.

getColor(n);

Let's see them in action:

console.log(colorGradient.getArray());
// outputs ["#4e4ab9", "#5d68c4", "#6d86ce", "#7ca4d9", "#8bc2e3"]

console.log(colorGradient.getColor(3));
// outputs #6d86ce

Example

Implementing javascript-color-gradient library into React.js application, using two gradient colors and 10 midpoints.

The following example is using four gradient colors and 20 midpoints.
