  • is it possible to run a custome user script after each page load?
    1 project | | 25 Jun 2022
    AFAIK, you could also use the remote api of firefox to inject scripts. But for that you need a framework like ref.

    Literally just went to a Github Project (puppeteer in our case) and sorted issues by most comments/reactions. The number one was "How to run on Ubunutu" or something similar. Actually, it's this issue right here:

    1 project | | 14 Jun 2022
    First, we need to create a Node.js* project and add npm packages puppeteer, puppeteer-extra and puppeteer-extra-plugin-stealth to control Chromium (or Chrome, or Firefox, but now we work only with Chromium which is used by default) over the DevTools Protocol in headless or non-headless mode.

  • Is there a way to scrape a website's inventory pages to have them populate on my site?
    1 project | | 10 Jun 2022
    It's really not that hard. I've used Puppeteer ( in the past for similar projects. If you don't have any programming background, search for third party scraping tools with a built-in rotating proxy service - there are a few about, just give it a Google.
  • How We Automated our End-to-End Testing from the First Line of Code
    2 projects | | 8 Jun 2022
    After some research and understanding of what we need to design and build, we chose Docker Compose, RPyC, and Puppeteer for our test automation suite. The tech stack for our E2E testing is completely independent of the stack we chose for our product of course (we’ll dive into this in a separate post), and it can run with any product that is able to run Docker and Docker Compose in their environment.
  • How can I get browser automation solely in backend?
    1 project | | 8 Jun 2022
    I'd recommend using Puppeteer, which can drive Chrome in headful or headless modes. In dev mode, you can spin up a headful browser so that you can watch what your script is doing and debug it. In production, you'll just flip the condition to headless.
