Another solution I tried was manually removing the HeadlessChrome substring from the userAgent in case the site was blocking it, but that didnt work either. The server will start and listen for requests on port 3000. This will build the Docker image and run a new container based on the image. To run the built image, use the following: docker run -rm -p 3000:3000 headless-chrome. 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. docker build -platform linux/amd64 -t headless-chrome. My research suggests that the browser is closing before the download completes possibly? Ive added a wait of about 15 seconds, which is much longer than it should need to download the file, but still not getting anything. Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol.
Im able to run it with no problems while headless: false, but when headless:true, the file does not download. Puppeteer creates its own browser user profile which it cleans up on every run.Im running a script that logs into an authenticated session on a website and clicks a button to download an excel file.
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. You can also use Puppeteer with Firefox Nightly (experimental support). Puppeteer is a Node library which provides a high-level API to control 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: Headless mode is a popular choice for browser automation through projects like Puppeteer or ChromeDriver. Puppeteer will be familiar to people using other browser testing frameworks. You can use it next to puppeteer, puppeteer-core or puppeteer-firefox, interchangeably. All examples below use async/await which is only supported in Node v7.6.0 or greater. npm install browserless puppeteer -save browserless is backed by puppeteer, so you need to install it as well. Starting from v3.0.0 Puppeteer starts to rely on Node 10.18.1+. Prior to v1.18.1, Puppeteer required at least Node v6.4.0.
