Playwright Browser Automation

Script-based browser automation across chromium, firefox and webkit: navigate, interact, wait, assert, capture.

Scope: cross-browser E2E flows and UI test scripts. For debugging a live page — console/JS errors, failed requests, Core Web Vitals, WebSocket frames, CDP domains — use chrome-devtools instead.

Quick Start

# Navigate and screenshot
node scripts/playwright.js navigate "https://example.com"
node scripts/playwright.js screenshot "https://example.com" --output page.png

# Interact with elements
node scripts/playwright.js click "https://example.com" --selector "button.submit"
node scripts/playwright.js type "https://example.com" --selector "input#search" --text "hello"
node scripts/playwright.js scroll "https://example.com" --direction down --amount 500

# Extract content
node scripts/playwright.js content "https://example.com"
node scripts/playwright.js evaluate "https://example.com" --expression "document.title"

# Generate PDF
node scripts/playwright.js pdf "https://example.com" --output page.pdf
