Not able to capture image while generating pdf using puppeteer API

Could you try one of these two approaches? This script tries to scroll to the bottom by comparing scroll heights (as you did) or waiting for the element marking the stream end to be visible. All scroll logic is placed inside functions evaluated in the browser context. Both functions return tweet count in the full page to compare the result with the user tweet count declared at the top of the timeline. Also, I've changed the delay to 3 sec for the first approach as it seems sometimes 1 sec is a too small amount for scroll height to be changed.

https://stackoverflow.com/questions/55073738/puppeteer-scrolling-down-twitter-timeline-stops

You have two options:

Wait until the request/response is finished
Wait until the second dropdown box is filled

Option 1: Wait for the request

Use page.waitForResponse to wait for a specific response to happen, before you want your script to continue. Example:

await page.waitForResponse(response => response.url().includes('/part-of-the-url'));

Option 2: Wait for the second dropdown box to be filled

As you are saying that the request populates another dropdown box (I'm guessing a select element), you could use the page.waitForFunction function to wait until the select box is filled. Example:

await page.waitForFunction(() => document.querySelector('#selector-of-second-selectbox').length > 0);

The length attribute on a select box will check how many option elements are inside. So by checking if length is non-zero, this is wait until the select box is filled. This assumes, that the select box is empty at the start (length is 0).

https://stackoverflow.com/questions/56530424/puppeteer-wait-for-request-to-finish-after-dropdown-selection

The answer is Yes and No.

You can connect to an existing using the connect function:

const browserURL = 'http://127.0.0.1:21222';
const browser = await puppeteer.connect({browserURL});

But, if you want to use those 2 lines you need to launch Chrome with the "--remote-debugging-port=21222 argument.

elementHandle.getProperty('parentNode')

You can use elementHandle.getProperty() to obtain the parentNode property of the current ElementHandle:

const current_element = await page.$('#example');
const parent_node = await current_element.getProperty('parentNode');

await parent_node.click();

https://stackoverflow.com/questions/60492723/puppeteer-how-to-get-parentnode-without-using-evaluate

It seems this is what you need to achieve your goal with puppeteer:

const hrefs = await page.evaluate(() => {
  let links = [];
  let elements2 = document.querySelectorAll('a');
  for (let element2 of elements2)
    links.push(element2.href);
  return links;
});

https://stackoverflow.com/questions/67945354/puppeteer-get-all-a-href-links

You have to register localStorage item like this:

await page.evaluate(() => {
  localStorage.setItem('token', 'example-token');
});

You should do it after page page.goto - browser must have an url to register local storage item on it. After this, enter the same page once again, this time token should be here before the page is loaded.

Here is a fully working example:

const puppeteer = require('puppeteer');
const http = require('http');

const html = `
<html>
  <body>
    <div id="element"></div>

    <script>
      document.getElementById('element').innerHTML = 
        localStorage.getItem('token') ? 'signed' : 'not signed';
    </script>
  </body>
</html>`;

http
  .createServer((req, res) => {
    res.writeHead(200, { 'Content-Type': 'text/html' });
    res.write(html);
    res.end();
  })
  .listen(8080);

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.goto('http://localhost:8080/');

  await page.evaluate(() => {
    localStorage.setItem('token', 'example-token');
  });

  await page.goto('http://localhost:8080/');

  const text = await page.evaluate(
    () => document.querySelector('#element').textContent
  );

  console.log(text);
  await browser.close();

  process.exit(0);
})();

https://stackoverflow.com/questions/51789038/set-localstorage-items-before-page-loads-in-puppeteer

Since Puppeteer does not currently support navigation to a PDF document in headless mode via page.goto() due to the upstream issue, you can use page.setRequestInterception() to enable request interception, and then you can listen for the 'request' event and detect whether the resource is a PDF before using the request client to obtain the PDF buffer.

After obtaining the PDF buffer, you can use request.abort() to abort the original Puppeteer request, or if the request is not for a PDF, you can use request.continue() to continue the request normally.

Here's a full working example:

'use strict';

const puppeteer = require('puppeteer');
const request_client = require('request-promise-native');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.setRequestInterception(true);

  page.on('request', request => {
    if (request.url().endsWith('.pdf')) {
      request_client({
        uri: request.url(),
        encoding: null,
        headers: {
          'Content-type': 'applcation/pdf',
        },
      }).then(response => {
        console.log(response); // PDF Buffer
        request.abort();
      });
    } else {
      request.continue();
    }
  });

  await page.goto('https://example.com/hello-world.pdf').catch(error => {});

  await browser.close();
})();

https://stackoverflow.com/questions/53487375/puppeteer-how-can-i-get-the-current-page-application-pdf-as-a-buffer-or-file

I think document would only be available within page.evaluate (according to puppeteer documentation )

Try:

async function gallery(page) {
   await page.waitFor(3000);
   await page.evaluate(() => {
      document.querySelector('div.image').click();
   })
}

https://stackoverflow.com/questions/55702626/why-i-got-document-is-not-defined-error-in-puppeteer

In your example code you're using page.$eval, not page.$$eval. Since the former uses document.querySelector instead of document.querySelectorAll, the behaviour you describe is the expected one.

Also, you should change your pageFunctionin the $$eval arguments:

const hrefs = await page.$$eval('a', as => as.map(a => a.href));

Why You Should Use Puppeteer For Testing

Over the past decade the world has seen emergence of powerful Javascripts based webapps, while new frameworks evolved. These frameworks challenged issues that had long been associated with crippling the website performance. Interactive UI elements, seamless speed, and impressive styling components, have started co-existing within a website and that also without compromising the speed heavily. CSS and HTML is now injected into JS instead of vice versa because JS is simply more efficient. While the use of these JavaScript frameworks have boosted the performance, it has taken a toll on the testers.
