It’s a useful tool that can help you write and maintain simple and automated tests in your application using headless Chrome or Chromebit devices, with no need for any browser extensions. It helps automate and simplify development with a high-level API that lets you control headless Chrome over the DevTools Protocol. Puppeteer is an open-source Node.js library developed by Google. To start, let’s take a closer look at the API we’ll use: Puppeteer. With the right API, you can run KeyLines or ReGraph in a virtual Chrome browser, and generate high-res exports whenever you need them. It means that applications built with our toolkits can deliver quick and clear digital or printed exports that don’t compromise on image quality.īut what if you’re working offline, on a local server? Our libraries usually run in your browser so that they can do things like handle new fonts, and measure the size of the text and font icons in your charts. KeyLines and ReGraph, our graph visualization toolkits, include a high-res export function so your users can share visualizations as images or customized PDF summaries. In this Puppeteer tutorial, I’ll show you how to create a simple server application using the Puppeteer library with KeyLines.
