It has extensive capabilities when it comes down to coding certain tasks like server-side applications or peer-to-peer networking protocols like Websockets. Node.js has become immensely popular over the years as an essential part of many software development projects. It was first released in 2009 by Ryan Dahl who was one of its original contributors (with some help from Douglas Crockford). Node.js is an open-source JavaScript runtime built on Chrome's V8 engine that runs on Linux, Mac OS X, and Windows operating systems. Puppeteer uses the WebDriver protocol to connect with the browser and simulate user interaction with HTML elements or pages. With it, you can run tests in the browser and then see the results in real-time on your terminal. Puppeteer lets you automate the testing of your web applications. It is a tool for automating testing in your application using headless Chrome or Chromebit devices, without requiring any browser extensions like Selenium Webdriver or PhantomJS. Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol. How to run headless Chrome tests on a CI server.How to set up your first test with Puppeteer.In this guide, we'll explore the basics of using Puppeteer with Node.js so you can start automating your tests. Let me know your thoughts on this solution to creating server-side pdf reports, and if you run into any issues, feel free to contact me.Puppeteer is a JavaScript library that allows you to script and interact with browser windows. Html templating framework from the Mustache family. This allows for Partial templating (fancy talk for components) and custom and built-in helper functionality to expand on our logic.Įxample using partials and built in blocks The tools we need to make this happen: 1. We're all set to feed our sweet, sweet data into a report. We already have the base of our project up and running Node/Express, and some type of ORM and DB solutions. Generating a report can take a while depending on file size.Puppeteer itself adds extra build time and size to your deployments.We won't be able to use dev tools to debug irregularities once the PDF is compiled and rendered.We won't have access to css media props other than "screen." (no "page-break-after" or the print media type).Pages will manually need to be constrained.The challenges of creating these PDF reports:īecause we’re using a template framework to access standard web technologies along with puppeteer to manage the pdf, we'll need to think about these things during development: An example of a PDF page generated using this method.
