A PDF SDK built on a design schema, not a viewer

import { pdfToJson } from "@polotno/pdf-import";
import { jsonToPDFBlob } from "@polotno/pdf-export/browser";
import { createStore } from "polotno/model/store";

// 1. Parse — text, images, and vector paths come back as typed elements
const json = await pdfToJson({ pdf: await file.arrayBuffer() });

const store = createStore({ key: "YOUR_KEY" });
store.loadJSON(json);
await store.waitLoading();

// 2. Edit — programmatically, or hand the store to the editor UI
store.pages[0].children
  .filter((el) => el.type === "text" && el.text.includes("{{name}}"))
  .forEach((el) => el.set({ text: el.text.replace("{{name}}", customer) }));

// 3. Export — vector PDF, text still selectable
const blob = await jsonToPDFBlob(store.toJSON());
