import axios from 'axios';
import Handlebars from 'handlebars';

const templateSource = fs.readFileSync('./templates/certificate.hbs', 'utf8');

  description: 'In recognition of successfully completing the program.',
  year: '2026',
  signatureLeft: 'Program Director',

};

const html = template(params);

const response = await axios.post(

  { html },
  {
    responseType: 'arraybuffer',
    headers: {
      'X-API-Key': process.env.HTML2PDF_API_KEY,

);

fs.writeFileSync('./certificate.pdf', response.data);
