Nodejs Puppeteer Tutorial #4 - Scrape multiple pages in parallel using puppeteer-cluster

This puppeteer tutorial is designed for beginners to learn how to use the node js puppeteer library to perform web scraping, testing, and creating website bots. Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Puppeteer runs headless by default but can be configured to run full (non-headless) Chrome or Chromium.

Man, you are holy
I'm struggling with parser long time, and server run out of resources cause of leaks
hope I will implement your code properly

This looks like that we can perform a specific task in parallel to all the pages, what if have unique tasks that need to be done on multiple pages in parallel ?

Great tutorial Mike! Thanks a lot. One question... how can I create json file from different scraped pages and keep update that json data every minute? Any suggestion for that task? Thanks

Please I need your help, I can’t scrape data on mobile devices using peppeteer cluster after setting the user agent to a mobile device

Amazing tutorial, i know its been a while but could you please answer my question? I got everything working and can scrape multiple pages at the same time but i want to make a request for each page. I currently make the request in the await.cluster.task function but each request can take a while (around 1 minute or even 2) and I want to make sure it finishes before continuing. I currently get the error: Error Crawling: "websiteurl": Timeout 30000

Hi, thanks a lot .

in the cuncureency_page mode, we can open mutiple tabs on the same single browser at the same time, but my problme is after the on url finish, the tab will be close and a new one will open for the next url, I think this closing and openning tab for each url will consume more time and machine resources, do you now how I can navigate to another url at the same tab instead of closing it and open a new one for the next url ?
