Usage

Linear gradient parser comes in handy when you need get a svg linear gradient as background. It can accepts both SVG linearGradient string / Json as input in order to produce it's background.

import parser from 'linear-gradient-parser';

// SVG String input
const linearGradientString = `
<linearGradient xmlns="http://www.w3.org/2000/svg" gradientUnits="userSpaceOnUse" x1="17.5001" y1="32" x2="17.5001" y2="2.9711">
    <stop offset="0" style="stop-color:#FCB3A4"/>
    <stop offset="1" style="stop-color:#DA5899"/>
</linearGradient>
`

const stringResult = parser.getBackground(linearGradientString);

console.log(stringResult) 
//outputs : {background: "linear-gradient(0deg, rgb(252, 179, 164) 0%, rgb(218, 88, 153) 100%)", angle: 0}

// JSON input
const linearGradient = {
    x1: '17.5001',
    y1: '32',
    x2: '17.5001',
    y2: '2.9711',
    stops: [
        { color: '#FCC3A4', offset: '0', opacity: 0.5 },
        { color: '#AAA899', offset: '1' }
    ]
};

const jsonResult = parser.getBackground(linearGradient);

console.log(jsonResult) 
//outputs : {background: "linear-gradient(0deg, rgb(252, 179, 164) 0%, rgb(218, 88, 153) 100%)", angle: 0}

// Using angle generator
const gradientCords = parser.getGradientCords(90);

//outputs : { x1: 0, x2: 1, y1: 0, y2: 0 }
