![]() The code snippet below is a simple example of running parallel downloads with Puppeteer.Ĭonst downloadPath = path. □ If you are not familiar with how child process work in Node I highly encourage you to give this article a read. We can combine the child process module with our Puppeteer script and download files in parallel. 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. This project has been integrated with puppeteer-to-istanbul module which helps in generating the coverage by puppeteer to istanbul reports.įor contributors who want to improve this repo by contributing some code, reporting bugs, issues or improving documentation - PR's are highly welcome, please maintain the coding style, folder structure, detailed description of documentation and bugs/issues with examples if possible.Const browser = await puppeteer. They can be customized according to user's specific needs. "test": "npm run cucumber & npm run report"Ĭurrently this project has been integrated with cucumber-html-reporter, which is generated in the reports folder when you run npm test. format 'json./reports/json/cucumber_report.json'",
