Puppeteer utilises the Node library that gives a top-class API for managing Chromium or Chrome browsers. If we follow the npm trends for Puppeteer download for the last few years, we shall observe an upward trend towards the use of Puppeteer (available from the below link) − Puppeteer is like a development tool as it is capable of performing a majority of tasks performed by a developer like handling requests and responses, locating elements, network traffic and performance, and so on. We can open DevTools in the Chrome browser, by pressing F12 or Command+Option+C(in MacOS).

It is mostly used to manage the internal features of the Chromium browser. Puppeteer is not considered as an automation tool like Selenium, Cypress, Protractor, and so on. The actions like web page crawling and scraping can be performed with Puppeteer. It can be used to test applications developed in Angular and Angularjs. Puppeteer can be used for the automating majority of UI testing, keyboards, mouse movements, and so on. However, it can also be used for non-headless execution on browsers like Chrome/Chromium/Edge/Firefox.

Puppeteer contains APIs to interact and manage Chrome browser in headless mode or Chromium (following the protocols in DevTools). Puppeteer is based on the Node.js library and is open-source. Puppeteer is used for automation and streamlining of the frontend development and testing respectively.

You should find Puppeteer executes successfully, provided proper Chrome flags are used.

Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction.

disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.

If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host.

no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container).

Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering.

disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host.
