Export PDF annotations in Node.js

You can export annotations as Instant JSON using the instance.exportInstantJSON() API method:

import fs from "node:fs";
import { load } from "@nutrient-sdk/node";


const pdfDoc = fs.readFileSync("source.pdf");
const myInstantJSON = JSON.parse(
  fs.readFileSync("instantjson.json", "utf-8")
);


const instance = await load({
  document: pdfDoc,
  instantJSON: myInstantJSON
});
const output = await instance.exportInstantJSON();
await instance.close();


fs.writeFileSync("output.json", JSON.stringify(output));
