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.
Installation
For Node.js: Install the javascript-color-gradient npm module:
npm install javascript-color-gradientThen import the module into your JavaScript:
import Gradient from "javascript-color-gradient";Demo
A demo is worth a thousand words.
Note: All the examples are using ES6, be sure is supported in your browser or modify as needed, Chrome recommended.
Methods
| Method | Description | |
|---|---|---|
setColorGradient() |
Initializes {Gradient} with two or more hex color values. Should always be defined. |
|
setMidpoint(n) |
Defines number of midpoints. Defaults to 10. | |
getColors() |
Returns an array of hex color values . | |
getColor(n) |
Returns single hex color value corresponding to the provided index. |
Usage
Using 2 colors and default (10) midpoints to generate an array of hex color values:
import Gradient from "javascript-color-gradient";
const gradientArray = new Gradient()
.setColorGradient("#3F2CAF", "e9446a")
.getColors();
console.log(gradientArray);
// ["#502ea8", "#6131a1", "#72339a", "#833693", "#94388d", "#a53a86", "#b63d7f", "#c73f78", "#d84271", "#e9446a"]Using 4 colors and 20 midpoints to generate an array of hex color values :
import Gradient from "javascript-color-gradient";
const gradientArray = new Gradient()
.setColorGradient("#3F2CAF", "#e9446a", "#edc988", "#607D8B")
.setMidpoint(20)
.getColors();
console.log(gradientArray);
// ["#5930a5", "#72339a", "#8c3790", "#a53a86", "#bf3e7b", "#d84271", "#e94b6c", "#ea5f70", "#ea7375", "#eb8779", …]Using two colors and default (10) midpoints to return single hex color value corresponding to the provided index:
import Gradient from "javascript-color-gradient";
const colorAtIndexTwo = new Gradient()
.setColorGradient("#3F2CAF", "e9446a")
.setMidpoint(20)
.getColor(2);
console.log(colorAtIndexTwo);
