Child process is how Node.js handles parallel programming. We can fork multiple child_proces in Node. Our CPU cores can run multiple processes at the same time. □ Learn more about the single threaded architecture of node here Therefore if we have to download 10 files each 1 gigabyte in size and each requiring about 3 mins to download then with a single process we will have to wait for 10 x 3 = 30 minutes for the task to finish. It can only execute one process at a time. You see Node.js in its core is a single-threaded system. However, if you have to download multiple large files things start to get complicated. In this next part, we will dive deep into some of the advanced concepts. I hope you found this article helpful.Const browser = await puppeteer. This same approach can be used to convert arbitrary pages to PDF in your. This code was effortless to slip into their automation script, and successfully generated PDF versions of their invoices.

Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium. Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. This isn't the type of task I usually do, but my first instinct was to use Puppeteer. The freelancer's existing workflow was to manually open each invoice in Chrome, and use the "Print to PDF" functionality to generate a PDF. They'd automated everything up until that point, but some of their clients wanted the invoices sent as PDF documents. They were tech savvy, and were using a templating engine to generate beautiful HTML documents from a template and some data files. I recently had a freelancer ask me for help with the automated generation of their invoices.
