dom-to-point

Q:What is this thing solving?

If you want to get an SVG like the red thing below

Install

yarn add dom-to-points // Package size: 795 B

Usage

import {getPolygonString} from 'dom-to-points'
// or const {getPointsArray, getPolygonString} = require('dom-to-points')

const points = getPolygonString('.item')
// or const points = getPolygonString([...document.querySelectorAll('.item')])

console.log('polygonString', points)

/*
0,0 300,0 300,100 0,100 0,100 200,100 200,200 0,200 0,200 200,200 200,300 0,300 0,300 300,300 300,400 0,400 0,400 0,300 0,300 0,200 0,200 0,100 0,100 0,0
*/

const points = getPointsArray('.item')
// or const points = getPointsArray([...document.querySelectorAll('.item')])

console.log('points', points)

/*
[ 
    [ 0, 0 ],
    [ 300, 0 ],
    [ 300, 100 ],
    [ 0, 100 ],
    [ 0, 100 ],
    [ 200, 100 ],
    [ 200, 200 ],
    [ 0, 200 ],
    [ 0, 200 ],
    [ 200, 200 ],
    [ 200, 300 ],
    [ 0, 300 ],
    [ 0, 300 ],
    [ 300, 300 ],
    [ 300, 400 ],
    [ 0, 400 ],
    [ 0, 400 ],
    [ 0, 300 ],
    [ 0, 300 ],
    [ 0, 200 ],
    [ 0, 200 ],
    [ 0, 100 ],
    [ 0, 100 ],
    [ 0, 0 ] 
]
*/

Q: What then?

You could make a polygon with the data and add it to an SVG.

You could use a library, such as SVG.js or paper.js

Check this jsfiddle demo.
