const exampleData = {
    title: 'Example HTML to PDF',
    type: 'html',
    data: {
      html: `
        <h1 class='header-one'>What is Lorem Ipsum?</h1>
        <p>
          Lorem Ipsum is simply dummy text of the printing and typesetting
          industry. Lorem Ipsum has been the industry's standard dummy text
          ever since the <strong>1500s</strong>, when an unknown printer took
          a galley of type and scrambled it to make a type specimen book.
        </p>
      `,
      css: `
        body { font-size: 14px; color: #171717; }
        .header-one { text-decoration: underline; }
      `,
    },
  }

  const anvilClient = new Anvil({ apiKey })
  const { statusCode, data } = await anvilClient.generatePDF(exampleData)

  console.log('Making HTML PDF generation request...')
  console.log('Finished! Status code:', statusCode) // => 200, 400, 404, etc

  // `data` will be the filled PDF binary data. It is important that the
  // data is saved with no encoding! Otherwise the PDF file will be corrupt.
  fs.writeFileSync(outputFilepath, data, { encoding: null })
  console.log('Generated PDF saved to:', outputFilepath)
