Puppeteer creates its own browser user profile which it cleans up on every run. This article describes some differences for Linux users. See this article for a description of the differences between Chromium and Chrome.
See Puppeteer.launch() for more information.
Let’s install it using npm: npm install puppeteer Building Our Scraper Now, let’s start to build our scraper by creating a new file, called scraper.js. Get started Overview of Puppeteer An explanation of what Puppeteer is and the things it can do. Puppeteer is a Node.js API that allows us to talk to a headless Chrome instance programmatically. It can also be configured to use full (non-headless) Chrome or Chromium. You can also use Puppeteer with Firefox Nightly (experimental support). Puppeteer Puppeteer is a Node library which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. const puppeteer = require ( 'puppeteer' ) Ĭonst browser = await puppeteer. You create an instance of Browser, open pages, and then manipulate them with Puppeteer's API.Įxample: navigating to and saving a screenshot as example.png: Puppeteer will be familiar to people using other browser testing frameworks. This is the site I'm trying to download from The reason I'm using Puppeteer is because I can't find a supported API to get this data (if there is one happy to try it) The link is 'Download Raw Data' My script runs to the end, but doesn't seem to actually download any files. All examples below use async/await which is only supported in Node v7.6.0 or greater. Starting from v3.0.0 Puppeteer starts to rely on Node 10.18.1+. 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. Versions from v1.18.1 to v2.1.0 rely on Node 8.9.0+. Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol.
) Īwait page.Prior to v1.18.1, Puppeteer required at least Node v6.4.0. Specifies wether it allows downloading multiple files or notĪwait page._nd('tDownloadBehavior', 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() 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.
