Key Advantages

• One Line of Code: Start scraping instantly with Zenrows’ Browser Sessions. No complicated setup. Just a simple API call that does all the heavy lifting for you.
• Dynamic Web Content Extraction: Many websites rely on JavaScript to display content dynamically. Browser Sessions simulates a real user session, allowing you to extract data even from single-page applications (SPAs) or websites that load content asynchronously.
• Handling User Interactions: Simulate user actions like clicking, scrolling, or waiting for elements to load, all while avoiding IP blocks and ensuring the data is extracted seamlessly.
• Geolocation Targeting: Access localized content by selecting from millions of IPs across 190+ countries, bypassing geo-restrictions to scrape the data you need.
• IP Auto-Rotation: Rotate IPs with every request to avoid bans and blocks, ensuring your scraping remains undetected.

Tips for Optimal Performance

1. Manage Session Duration: Keep session durations as short as possible since session time is billed by the minute.
2. Reuse Browser Sessions: For multiple operations on the same site, reuse the browser session rather than creating a new one each time.
3. Use Proper Page Closure: Always close pages when done to free up resources:
   // Close individual pages when done
   await page.close();
   
4. Set Reasonable Timeouts: Use appropriate timeouts for your operations to prevent long-running sessions:
   // Set navigation timeout
   await page.goto(url, { timeout: 30000 });
   
   // Set selector timeout
   await page.waitForSelector('.element', { timeout: 15000 });
   
5. Optimize Resource Usage: Block unnecessary resources when they’re not needed:
   // Block images, fonts, etc.
   await page.setRequestInterception(true);
   page.on('request', (request) => {
     if (request.resourceType() === 'image' || request.resourceType() === 'font') {
       request.abort();
     } else {
       request.continue();
     }
   });
   
6. Target Specific Countries Wisely: Only specify a country when needed for your use case, as more specific targeting might have different success rates.
