node-canvas error

Is there any other library I can use since `node-canvas` seems to be an issue, please recommend.

Is there any other library I can use since `node-canvas` seems to be an issue, please recommend.

I tried using node-canvas with jsbarcode to process barcode from a node application but node-canvas seems to be an issue ever since I tried implementing using it.I have tried rebuilding from source yet the error still a blocker.

const express = require('express');
const JsBarcode = require('jsbarcode');
const { createCanvas } = require('canvas');

const { handleErrors } = require('../helpers');

const router = new express.Router();

// Generate Barcode
router.get('/barcode', async (req, res) => {
const { data } = req.params;

try {
if (!data) {
return res.status(404).send();
}

const canvas = createCanvas(250, 100, 'image');
JsBarcode(canvas, data, {
fontSize: 24,
fontOptions: 'bold',
mod43: true,
});
const buffer = canvas.toBuffer();

res.set('Content-Type', 'image/png');
res.status(200).send(buffer);
} catch (e) {
handleErrors(e, res);
}
});

module.exports = router;

On the other hand, the error could be related to your Node version.
