Browser Automation

Browser Automation

Lightweight browser automation using 6 simple Node.js scripts. Use this for web scraping, SEO analysis, or extracting data from JavaScript-heavy sites.

When to use: Multi-page scraping, authenticated content, screenshots, JavaScript-rendered content When to use WebFetch: Simple HTML, single pages, no auth needed

Scripts

Located in ~/.claude/skills/browser-automation/resources/:

• browser-start.js - Launch Chrome with debugging
• browser-navigate.js <url> - Navigate to URL
• browser-eval.js '<javascript>' - Run JavaScript in page context
• browser-screenshot.js - Capture screenshot
• browser-cookies.js - Export cookies
• browser-close.js - Shutdown browser

Basic workflow

cd ~/.claude/skills/browser-automation/resources
node browser-start.js --headless
node browser-navigate.js "https://example.com"
node browser-eval.js 'Array.from(document.querySelectorAll("h2")).map(h => h.textContent.trim())' --json > headings.json
node browser-close.js
