When you click add buildpack, simply paste that url into the input, and click If you do, # you'll need to launch puppeteer with: # browser.launch(). # If running Docker >= 1.13.0 use docker run's -init arg to reap zombie processes, otherwise # uncomment the following lines to have `dumb-init` as PID 1 # ADD /usr/local/bin/dumb-init # RUN chmod +x /usr/local/bin/dumb-init # ENTRYPOINT # Uncomment to skip the chromium download when installing puppeteer. & apt-get install -y google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst fonts-freefont-ttf libxss1 \ & sh -c 'echo "deb stable main" > /etc/apt//google.list' \ # Install latest chrome dev package and fonts to support major charsets (Chinese, Japanese, Arabic, Hebrew, Thai and a few others) # Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer # installs, work. To fix, you'll need to install the missing dependencies and the latest Chromium The bundledĬhromium that Puppeteer installs is missing the necessary shared library Getting headless Chrome up and running in Docker can be tricky. Instructions below might be still helpful if you are building your own image.
Starting from v16.0.0 we are shipping a Docker image via the In a Docker container until v3.0.x - see our historicalįor reference. 👋 We used Cirrus Ci to run our tests for Puppeteer To fix this, set jest -maxWorkers=2 in your test command. This is likely caused by Jest autodetecting the number of processes on theĮntire machine ( 36) rather than the number allowed to your container ( 2). Puppeteer creates its own browser user profile which it cleans up on every run.Jest args: -e2e -spec -max-workers=36Īt ChildProcess.spawn (internal/child_process.js:394:11) 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). 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. 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+. Prior to v1.18.1, Puppeteer required at least Node v6.4.0.
