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);
[
'#3f2caf', '#522fa7',
'#6531a0', '#783498',
'#8b3790', '#9d3989',
'#b03c81', '#c33f79',
'#d64172', '#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);
[
'#3f2caf', '#5a30a4',
'#753499', '#90378e',
'#aa3b83', '#c53f79',
'#e9526d', '#ea6772',

]
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")
