ddev-puppeteer

Simple Puppeteer script for measuring DDEV performance.

This tries to use a DDEV Drupal 11 project as a measure of performance using a web install of the demo_umami profile.

• Make sure you have installed chromium somehow, and export PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true.
• If you don't have it installed, use sudo apt install chromium-browser or brew install chromium or whatever is appropriate for your system. On Apple Silicon, brew install chromium --no-quarantine (see blog). These are better than letting puppeteer download its own version of Chromium.
• Since you have manually installed chromium, export PUPPETEER_EXECUTABLE_PATH="$(which chromium)" to set the path to the chromium executable.
• Install with npm init && npm i puppeteer async.
• The project named in ddev-puppeteer.js should be a standard Drupal 11 install as per the DDEV Drupal 11 quickstart
• Edit site and sitedir in ddev-puppeteer.js.
• Set up the project with Mutagen or Colima or whatever permutation you like.
• The project should already be running.
• Run the test with node ddev-puppeteer.js.

Notes

• This is using the Drupal demo_umami profile, which takes longer than standard.
• The script resets php-fpm at the beginning to make sure we start without a PHP OPcache. This may or may not be fair.
• To see what’s happening in the install you can change puppeteer.launch({headless: true}) to puppeteer.launch({headless: false}).
• The Drush install is ddev mysql -e "DROP DATABASE IF EXISTS db; CREATE DATABASE db;" && ddev exec killall -USR2 php-fpm && rm -rf web/sites/default/files/* && ddev mutagen sync && time ddev drush si demo_umami -y

Thanks so much to @froboy and his inspiring measurements in https://gist.github.com/froboy/f237bf62cfde5350c0849c6e9aab0c71
