Tell puppeteer where to download files Chrome defaults to downloading files in various places, depending on the operating system. Install Puppeteer Install NodeJS: NodeJs is a free open source server environment which can be run in different platforms. 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. Now that is done we can instrument puppeteer to use it as the directory to download files. Install Puppeteer To start the development of Puppeteer scripts, we need to install and configure the below components 1. Here we generate a CSV file and have the browser download it await page. Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol. ) Īwait page.Const puppeteer = require ( 'puppeteer' ) Ĭonst browser = await puppeteer.launch() The browser is downloaded to the HOME/.cache/puppeteer folder by default (starting with Puppeteer v19.0.0). Specifies wether it allows downloading multiple files or notĪwait page._nd('tDownloadBehavior', When you install Puppeteer, it automatically downloads a recent version of Chrome for Testing (170MB macOS, 282MB Linux, 280MB Windows) that is guaranteed to work with Puppeteer. With it, you can run tests in the browser and then see the results in real-time on your terminal. Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium. Puppeteer lets you automate the testing of your web applications. Most of the things that were done in the browser manually can be done by using puppeteer. It allows developers to write and maintain simple and automated tests.
My question is, is there a way to wait for a download to complete using Node+Puppeteer? I have tried using waitUntil: 'networkidle0 and networkidle2 but both seem to wait forever.Ĭode below: const path = require('path') Ĭonst browser = await puppeteer.launch() Puppeteer is a library which provides a high-level API to control Chrome, Chromium, or Firefox Nightly over the DevTools Protocol. Puppeteer is an open-source library for Node.js that helps in automating and simplifying development by providing control over the Developers tools. I have a script made using node.js and puppeteer which downloads a file from a button (which doesn't redirect to a url), so right now i'm using await await page.waitForTimeout(1000) to wait for the download to complete but it has a few flaws, such as:ĭepending on the connection, the download might take more than 1000ms to finish, as well as it might take less, which wouldn't make sense to wait more than what took to finish the download.
