How to use in a backend Node JS environment?

[Colton1070]

I'm not using this on a website.

I am frustrated to worlds end trying to find a working heatmap solution using node.js. This package tells you how to install it - and that's it. What?

How do I actually use it for that use? Is it not possible? I am ideally trying to take an image, take my data, map the data on the image, spit it out of my server. That shouldn't be that hard... Am I going to have to jerry rig my own solution with node-canvas? Why?

I tried the "alternative" npm packages but they have corroded into dust. What am I missing?

It would be nice to be able to do:

const heatmap = require('heatmap.js');
const Canvas = require('canvas');

const canvas = Canvas.createCanvas(1024, 512);
const ctx = canvas.getContext('2d');
let background = await Canvas.loadImage('./assets/image.png');
ctx.drawImage(profilecardbackground, 0, 0, canvas.width, canvas.height);

let map = heatmap.create({
    data: [{ x: 10, y: 15, value: 5}, ...],
    context: ctx
});

Or another way - it doesn't matter to me as long as it's possible!
