As you wrote in the comment yes: vCards JS uses NodeJS.

According to the vCards-js/README.md:

Install:

npm install vcards-js --save

Usage:

Simple example of how to create a basic vCard and how to save it to a file, or view its contents from the console:

const vCard = require('vcards-js');

//create a new vCard
vCard = vCard();

//set properties
vCard.firstName = 'Eric';
vCard.middleName = 'J';
vCard.lastName = 'Nesser';
vCard.organization = 'ACME Corporation';
vCard.photo.attachFromUrl('https://avatars2.githubusercontent.com/u/5659221?v=3&s=460', 'JPEG');
vCard.workPhone = '312-555-1212';
vCard.birthday = new Date('01-01-1985');
vCard.title = 'Software Developer';
vCard.url = 'https://github.com/enesser';
vCard.note = 'Notes on Eric';

//save to file
vCard.saveToFile('./eric-nesser.vcf');

//get as formatted string
console.log(vCard.getFormattedString());

Also you can use vCards JS on your website. Below is an example of how to get it working on Express 4:

const express = require('express');
const router = express.Router();

module.exports = function(app) {
  app.use('/', router);
};

router.get('/', function(req, res, next) {

  const vCard = require('vcards-js');

  //create a new vCard
  vCard = vCard();

  //set properties
  vCard.firstName = 'Eric';
  vCard.middleName = 'J';
  vCard.lastName = 'Nesser';
  vCard.organization = 'ACME Corporation';

  //set content-type and disposition including desired filename
  res.set('Content-Type', 'text/vcard; name="enesser.vcf"');
  res.set('Content-Disposition', 'inline; filename="enesser.vcf"');

  //send the response
  res.send(vCard.getFormattedString());
});
