JS Rendering

js_render: boolean | false;

What's This?

Websites can display content in two main ways: static content that's always there when the page loads, and dynamic content that appears or changes due to JavaScript. The js_render option determines how our scraper views this content.

How Does it Work?

  • Default (js_render=false): The scraper quickly retrieves the website's initial content without processing any JavaScript. This method is efficient and less demanding.

  • With Rendering (js_render=true): The scraper processes the website's JavaScript, ensuring it captures all content, including the dynamic parts. This approach is thorough but might take a bit more time.

When Should I Use This?

Activate js_render if you're dealing with websites that use JavaScript to show or modify their content, especially if you notice missing information in your scraped data.
