javascript-color-gradient

Lightweight JavaScript library, used to generate an array of color gradients by providing start and finish colors, as well as the required number of midpoints.

Demo

See Live Preview on CodeSandbox.

Note: All the examples are using ES6, be sure is supported in your browser or modify as needed, Chrome recommended.

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.
