Installation

npm install @docuseal/signature-maker-js

<script src="https://cdn.jsdelivr.net/npm/@docuseal/signature-maker-js/dist/index.cjs.min.js"></script>

Usage

Basic Usage with standard styles and default signature saving behavior:

<signature-maker
  id="signatureMaker"
  data-download-on-save="true"
>
</signature-maker>

---

Usage with default styles but custom signature saving behavior, such as uploading the signature to a server:

<signature-maker id="signatureMaker"><signature-maker>

<script>
  window.signatureMaker.addEventListener('save', (e) => {
    fetch('/save-signature', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ file: e.detail.base64 }),
    });
  })
</script>

---

Usage without a save signature button, embedded in another form. The signature will be stored in a form field named signature:

<form id="myForm" method="POST" action="/submit-form">
  <input name="name" type="text">
  <signature-maker
    id="signatureMaker"
    data-with-submit="false"
  >
    <input type="hidden" type="file" name="signature">
  </signature-maker>
  <button type="submit">Submit</button>
</form>

---

Usage without a save signature button and tracking each signature change:

<signature-maker
  id="signatureMaker"
  data-with-submit="false"
>
</signature-maker>
<script>
  window.signatureMaker.addEventListener('change', (e) => {
    if (e.detail.base64) {
      fetch('/background-save-signature', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ file: e.detail.base64 }),
      });
    } else {
      console.log('No signature to save');
    }
  })
</script>

---

<signature-maker
  class="block my-8"
  data-save-button-text="Télécharger"
