Puppeteer Headful

Github Action for Puppeteer that can be ran "headful" or not headless.

Versioning of this container is based on the version of NodeJS in the container

Purpose

This container is available to Github Action because there are some situations, mostly testing Chrome Extensions, where you can not run Puppeteer in headless mode.

Usage

This action installs Puppeteer on top of a NodeJS container, so you have access to run npm scripts using args. For this hook, we hijack the entry point of the Dockerfile, so we can start up Xvfb before your testing starts.

name: CI
on: push
jobs:
  installDependencies:
    name: Install Dependencies
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install Dependencies
        uses: actions/setup-node@v2
        env:
          PUPPETEER_SKIP_CHROMIUM_DOWNLOAD: "true"
        with:
          args: install
      - name: Test Code
        uses: mujo-code/puppeteer-headful@16.6.0
        env:
          CI: "true"
        with:
          args: npm test

Note: You will need to let Puppeteer know not to download Chromium. By setting the env of your install task to PUPPETEER_SKIP_CHROMIUM_DOWNLOAD = 'true' so it does not install conflicting versions of Chromium.

Then you will need to change the way you launch Puppeteer. We export out a nifty ENV variable PUPPETEER_EXEC_PATH that you set at your executablePath. This should be undefined locally so it should function perfectly fine locally and on the action.

browser = await puppeteer.launch({
  args: ['--no-sandbox'],
  executablePath: process.env.PUPPETEER_EXEC_PATH, // set by docker container
  headless: false,
  ...
});
