PDF

Generate native PDF files from JSON and TypeScript.

Install

npm install @paperjsx/json-to-pdf

Requires Node.js >=18.

Quick Start

import { PdfEngine } from "@paperjsx/json-to-pdf";
import { writeFileSync } from "node:fs";

const buffer = await PdfEngine.render({
  meta: { title: "Monthly Update" },
  page: { size: "Letter", margin: 48 },
  children: [
    { type: "heading", value: "Monthly Update" },
    { type: "paragraph", value: "Revenue grew 18% month over month." },
  ],
});

writeFileSync("update.pdf", buffer);

Core API

• PdfEngine.render(document, options?) — returns a Uint8Array of the PDF.
• PdfEngine.renderStream(document, options?) — returns a Node Readable adapter. The complete PDF is buffered before the stream emits, so it does not reduce peak render memory.

Rendering is native — no Chromium, no Puppeteer — and deterministic for repeatable builds and tests. Supports text, layout, graphics, images, tables, links, and bookmarks.

Pro

@paperjsx/json-to-pdf-pro adds advanced typography, digital signatures, timestamps, PDF/A, linearization, and production/self-hosted commercial rights.

npm install @paperjsx/json-to-pdf-pro
