@e-sig/react

Framework-agnostic React UI for the self-contained PDF e-sign flow. No Next.js / Supabase / design-system coupling — pass a signEndpoint + callbacks.

npm i @e-sig/react react react-dom

import { SelfSignFlow, SelfSignedReceipt, SignaturePadCanvas } from "@e-sig/react";

<SelfSignFlow
  documentId={doc.id}
  signer={{ name, email }}
  preview={<YourDocumentPreview html={doc.body} />}
  signEndpoint="/api/esign/sign"   // POSTs { document_id, signature_image_data_url }
  onSigned={(result) => router.refresh()}
/>;

// once signed:
<SelfSignedReceipt
  signedPdfUrl={doc.signed_pdf_url}
  signatureImageUrl={doc.signature_image_url}
  signatory={doc.signatory}
  signedDate={doc.signed_at}
  downloadHref={(p) => `/api/esign/download/${encodeURIComponent(p)}`}
  backHref="/"
/>;

Components

• SignaturePadCanvas — wraps signature_pad; imperative handle (getImageDataURL → PNG data URL, clear, isEmpty). Fully prop-styled.
• SelfSignFlow — optional preview + canvas + consent checkbox + Sign button; POSTs to signEndpoint, calls onSigned(result). Labels/consent text are props.
• SelfSignedReceipt — download link + signature image + cert-fingerprint / IP metadata; downloadHref maps a storage path → a fetchable URL.

Uses Tailwind utility classes (incl. shadcn-style theme tokens like bg-primary, text-muted-foreground); they degrade gracefully without Tailwind and are overridable via className. Peer deps: react, react-dom. Dep: signature_pad. License: MIT.
