PDF

Generate and process native PDF files with the public SDK. @runstamp/pdf is an internal binding name and is not published on npm.

Install

npm install @runstamp/sdk

Requires Node.js >=18.14.1.

Quick start

import { runstamp } from "@runstamp/sdk";
import { writeFileSync } from "node:fs";

const input = await fetch("https://runstamp.com/demo-evidence/operation-evidence/pdf/pdf.render/input.json").then(r => r.json());
const result = await runstamp.operations.run("pdf.render", input);
if (!result.ok) throw new Error(result.error.message);
writeFileSync("update.pdf", result.value.bytes);

Core API (workspace-only)

These engine helpers are for Runstamp workspace development. They are not exports of @runstamp/sdk, and @runstamp/pdf is not on npm. SDK users call runstamp.operations.run.

• PdfEngine.render(document, options?): returns a Uint8Array of the PDF.
• PdfEngine.renderStream(document, options?): returns a Node Readable adapter. The full PDF is buffered before the stream emits, so peak render memory is not reduced.

Rendering is native, with no Chromium or Puppeteer, and is deterministic for repeatable builds and tests. It supports text, layout, graphics, images, tables, links and bookmarks.

Commercial boundary

All local PDF rendering ships in @runstamp/sdk. Pro adds company-wide production support and commercial assurance, not a different package or fidelity gate. See License & Pricing.
