![]() widely used to generate PDFs from web pagesĪ great place to start with npm libraries in this Full stack course.creation of server-side rendered versions of single-page apps (SPA's).Though its use case varies, some of the notable ones are as follows: Now we know what Puppeteer is, so let's check what all can be done using this powerful API. ![]() As it spins up a new Chrome instance every time it's initialized, it's not always performant but it's the most precise way to automate testing with Chrome as it uses the actual browser under the hood. This is the standard protocol that is used to expose Chrome's functionality to various development tools while chrome runs in headless mode for automation.Ī headless browser in this context chrome is a web browser, without a graphical user interface (GUI), which is mainly used for automated testing. It communicates with the browser using DevTools Protocol. It is powerful as it abstracts many nitty-gritty details we would have to deal with otherwise and therefore, makes things very easy for us. Puppeteer is nothing but a high-level API built by Google or in layman's terms it is a human-readable interface that's used to interact with the webpages through the browser (Chrome or Chromium). Let us get started by understanding what Puppeteer exactly is before we even start to see how it's utilized. KnowledgeHut provides a great resource to learn Node for the same. For a comprehensive understanding of how Puppeteer works you need basic knowledge of JavaScript, ES6+, and Node.js. It programmatically uses JavaScript to help us perform common actions on the Chromium browser, via a simple and easy-to-use API. Puppeteer is put together by the same team that was behind the making of Google Chrome the reason why it is so well maintained. Puppeteer runs headless by default but can be configured to run full (non-headless) Chrome or Chromium." "Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. The Puppeteer website describes it as follows. It assists developers in writing and maintaining simple and automated tests, due to which most of the things that were done in the browser manually can now be done by using the puppeteer. ![]() It is an open-source Node.js library that helps automate and simplify development by providing control over the browser Developer tools. Here is where 'Puppeteer' comes into the picture. Who doesn't want to automate mundane and repetitive manual tasks when it helps you become more efficient as a developer? Automating developer tools to simplify development and testing has become an integral part of web development as more teams are trying to focus on fast and efficient deliverables.
