I have a NextJs application with an api route, which calls an internal page to generate a pdf file.

This method generate the pdf file in my API route:

function serialize(obj) {
  var str = [];
  for (var p in obj)
    if (obj.hasOwnProperty(p)) {
      str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
    }
  return str.join("&");
};

async function generatePdf(body) {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  // Allows you to intercept a request; must appear before
  // your first page.goto()
  await page.setRequestInterception(true);

  // Request intercept handler... will be triggered with
  // each page.goto() statement
  page.on("request", (interceptedRequest) => {
    // Here, is where you change the request method and
    // add your post data
    var data = {
      method: "POST",
      postData: serialize(body),
      headers: {
        ...interceptedRequest.headers(),
        "Content-Type": "application/x-www-form-urlencoded",
      },
    };

    // Request modified... finish sending!
    interceptedRequest.continue(data);

    // Immediately disable setRequestInterception, or all other requests will hang
    page.setRequestInterception(false);
  });

  const response = await page.goto(process.env.GEN_PDF_URL, {
    waitUntil: "networkidle2",
  });

  const pdf = await page.pdf({
    path: "test.pdf",
    printBackground: true,
    format: "a4",
  });
  const responseBody = await response.text();
  console.log(responseBody);
  await browser.close();

  return pdf;
}

This method (sendEmail) is being called from the frontend, with the data (req.body) provided to generate the pdf page properly. I am passing that data as a parameter to the generatePdf method.

async function sendEmail(req, res) {
  const pdf = await generatePdf(req.body);
  ...

I am wondering if it is possible to generate that page using the provider data from the req.body in nextjs. So that I can generate the pdf files dynamically since the content of the Pdf page changes depending on what data I sent.
