JavaScript rendering

If the page you wish to scrape requires loading JavaScript to dynamically load all required data into the DOM, instead of setting up and using a headless browser by yourself, you can include the "X-Oxylabs-Render: html" header with your requests. All requests with this header included will be fully rendered, and all data will be stored in an HTML file or PNG screenshot (depending on the passed parameter).

JavaScript rendering takes more time to scrape the page. When using JavaScript rendering, set client side timeout value to 180 seconds.

To ensure lowest traffic consumption, our system does not load unnecessary assets during page rendering.

This parameter has two available values:

• html (HTML of a rendered page)

• png (raw bytes that can be saved as PNG)

Code examples

cURL

curl -k -v -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://ip.oxylabs.io/location' \
-H 'X-Oxylabs-Render: html'

Python

# Print result page to stdout

Scraping a website HTML

In this example, we will render the YouTube home page and scrape the page content. Normally Youtube homepage would look like this if Web Unblocker is used without Javascript rendering:

Youtube page example without JavaScript rendering

Adding the "X-Oxylabs-Render: html" header, as provided in the examples below, will enable Javascript rendering and return an HTML of a rendered page:

Forcing rendering on specific pages

For successful scraping, some page types of specific domains require rendering due to their dynamic content. Our system automatically enforces rendering for these pages, even if not explicitly set by the user.

Please note that rendered jobs consume more traffic compared to non-rendered jobs.

We want our users to be fully aware of this when scraping the following pages:

6KB

Force render domains.csv

This approach provides the best possible scraping experience, ensuring data accuracy and reliability from these challenging pages.

If you wish to disable rendering, send the render header without a value
