Getting a PDF from an URL in a secured session in NodeJS using Puppeteer, FileSystem, Axios and HTTPS

puppeteer-axios-pdf.js

/**
* Download a file (PDF in this case) from a secure URL after puppeteer login
**/

// Puppeteer init
const browser = await puppeteer.launch(puppeteerOptions);
const page = await browser.newPage();
page.setViewport({ width: 1366, height: 768 });

// Add login logic

// Save the cookies after login
const cookies = await page.cookies();

// Create a string to pass in request's headers
let cookiesString;
cookies.forEach((cookie) => {
  cookiesString += `${cookie.name}=${cookie.value};`;
});

// Get the PDF from the URL using saved cookies, https might be needed (https://www.npmjs.com/package/https)
axios
    .get("https://www.example.com/example.pdf", {
      responseType: "stream",
      headers: {
        Cookie: cookiesString,
      },
      withCredentials: true,
      httpsAgent: new https.Agent({
        rejectUnauthorized: false,
      }),
    })
    .then((response) => {
      response.data.pipe(fs.createWriteStream("example.pdf"));
    });
