Module: PlaywrightRuntime

Defined in:
app/services/playwright_runtime.rb

Overview

Resolves the Playwright CLI executable path for the current environment.

Lookup order:

  1. node_modules/.bin/playwright (dev, where yarn install provides it)
  2. ~/.playwright-driver/ (production standalone driver, bundles its own Node)
  3. npx playwright (fallback)

The standalone driver is installed with:
wget https://playwright.azureedge.net/builds/driver/playwright--linux.zip
unzip -d ~/.playwright-driver/
