Integrating Puppeteer Plugins with Cluster Functionality in Web Scraping

Other Questions Puppeteer

I’m building a web scraping project with Puppeteer to handle React-based sites. I’ve incorporated stealth and ad-blocker plugins along with TOR for IP rotation, but the setup is still unreliable.

I’ve recently come across Puppeteer-Cluster, which promises better multi-page crawling and task tracking. However, I’m uncertain how to merge it with my existing configuration that includes stealth, ad blocking, and TOR.

Below is a simplified version of my current setup:

const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
const AdBlocker = require('puppeteer-extra-plugin-adblocker');

puppeteer.use(StealthPlugin());
puppeteer.use(AdBlocker());

async function scrape() {
  const browser = await puppeteer.launch({
    args: ['--proxy-server=socks5://127.0.0.1:9050', '--no-sandbox'],
    ignoreHTTPSErrors: true
  });

  const page = await browser.newPage();
  await page.goto('https://example.com');
  // scraping logic here
  await browser.close();
}

scrape();

How can I integrate Puppeteer-Cluster with this setup to maintain the stealth, ad-blocker, and TOR capabilities? The provided cluster example is too bare and doesn’t clearly explain the integration. Any guidance would be appreciated.

hey claire, i’ve messed with puppeteer-cluster before. here’s a quick way to do it:

const cluster = await Cluster.launch({
  concurrency: Cluster.CONCURRENCY_CONTEXT,
  maxConcurrency: 2,
  puppeteer,
  puppeteerLaunchOptions: () => puppeteer.launch({
    args: ['--proxy-server=socks5://127.0.0.1:9050', '--no-sandbox'],
    ignoreHTTPSErrors: true
  })
});

this keeps ur plugins and tor setup. just add ur scraping logic in cluster.task(). good luck!

I’ve successfully integrated Puppeteer-Cluster with similar setups. Here’s a streamlined approach:

Define a custom launcher function that includes your plugins and TOR configuration. Then, incorporate this into the Cluster setup.

const customLaunch = () => puppeteer.launch({
args: [‘–proxy-server=socks5://127.0.0.1:9050’, ‘–no-sandbox’],
ignoreHTTPSErrors: true
});

const cluster = await Cluster.launch({
concurrency: Cluster.CONCURRENCY_CONTEXT,
maxConcurrency: 3,
puppeteer,
puppeteerLaunchOptions: customLaunch
});

This method preserves your existing configuration while harnessing Cluster’s capabilities. Adjust concurrency based on your needs and implement robust error handling for production use. Remember to close the cluster when finished to release resources properly.

I’ve faced similar challenges integrating Puppeteer-Cluster with stealth and proxy setups. Here’s how I approached it:

First, create a custom Puppeteer launcher function that incorporates your plugins and TOR setup. Then, pass this function to the Puppeteer-Cluster configuration.

const { Cluster } = require('puppeteer-cluster');

const customLaunch = () => puppeteer.launch({
  args: ['--proxy-server=socks5://127.0.0.1:9050', '--no-sandbox'],
  ignoreHTTPSErrors: true
});

async function run() {
  const cluster = await Cluster.launch({
    concurrency: Cluster.CONCURRENCY_CONTEXT,
    maxConcurrency: 2,
    puppeteerOptions: {
      headless: true
    },
    puppeteer: puppeteer,
    puppeteerLaunchOptions: customLaunch
  });

  await cluster.task(async ({ page, data }) => {
    await page.goto(data.url);
    // Your scraping logic here
  });

  // Add URLs to queue
  cluster.queue({ url: 'https://example.com' });

  await cluster.idle();
  await cluster.close();
}

run();

This approach maintains your existing setup while leveraging Cluster’s benefits. Adjust concurrency and add error handling as needed.
